So I got the job. Here's a story, never let anyone stop you from accomplishing your dreams!
It all started in 2010. Windows just crashed unrecoverably for the 3rd time in two years. Back then I wasn't good with computers yet so we got our tech guy to look at it and he said: "either pay for a windows license again (we nearly spend 1K on licenses already) or try another operating system which is free: Ubuntu. If you don't like it anyways, we can always switch back to Windows!"
Oh well, fair enough, not much to lose, right! So we went with Ubuntu. Within about 2 hours I could find everything. From the software installer to OpenOffice, browsers, email things and so on. Also I already got the basics of the Linux terminal (bash in this case) like ls, cd, mkdir and a few more.
My parents found it very easy to work with as well so we decided to stick with it.
I already started to experiment with some html/css code because the thought of being able to write my own websites was awesome! Within about a week or so I figured out a simple html site.
Then I started to experiment more and more.
After about a year of trial and error (repeat about 1000+ times) I finally got my first Apache server setup on a VirtualBox running Ubuntu server. Damn, it felt awesome to see my own shit working!
From that moment on I continued to try everything I could with Linux because I found the principle that I basically could do everything I wanted (possible with software solutions) without any limitations (like with Windows/Mac) very fucking awesome. I owned the fucking system.
Then, after some years, I got my first shared hosting plan! It was awesome to see my own (with subdomain) website online, functioning very well!
I started to learn stuff like FTP, SSH and so on.
Went on with trial and error for a while and then the thought occured to me: what if I'd have a little server ONLINE which I could use myself to experiment around?
First rented VPS was there! Couldn't get enough of it and kept experimenting with server thingies, linux in general aaand so on.
Started learning about rsa key based login, firewalls (iptables), brute force prevention (fail2ban), vhosts (apache2 still), SSL (damn this was an interesting one, how the fuck do you do this yourself?!), PHP and many other things.
Then, after a while, the thought came to mind: what if I'd have a dedicated server!?!?!?!
I ordered my first fucking dedicated server. Damn, this was awesome! Already knew some stuff about defending myself from brute force bots and so on so it went pretty well.
Finally made the jump to NginX and CentOS!
Made multiple VPS's for shitloads of purposes and just to learn. Started working with reverse proxies (nginx), proxy servers, SSL for everything (because fuck basic http WITHOUT SSL), vhosts and so on.
Started with simple, one screen linux setup with ubuntu 10.04.
Running a five monitor setup now with many distro's, running about 20 servers with proxies/nginx/apache2/multiple db engines, as much security as I can integrate and this fucking passion just got me my first Linux job!
It's not just an operating system for me, it's a way of life. And with that I don't just mean the operating system, but also the idea behind it :).20 -
Before anyone starts going batshit crazy, this is NOT a windows hate post. Just a funny experience imo.
So I was tasked with installing ProxMox on a dedicated server at my last internship. The windows admin was my guider (he could also do debian). (he was a really nice/chill guy)
So we were discussing what VM's we wanted and the boss (really cool dude by the way) said he wanted a VPS for storing some company stuff as well. Fair enough, what would we use? I suggested debian and centos. Then we started discussing what we'd do if the systems would fuck up etc (at installation or whatever).
So I didn't wanna look like a Linux Nazi so I suggested windows. Then the happy/positive guider/windows admin suddenly became dead serious (I was actually like 'woah' for a second) and said this:
No. We're not going to fucking use windows for this. For general servers etc sometimes, fair enough but we're talking about sensitive company data here. I don't want that data to be stored on a proprietary/closed source system, hell what if there's some kinda fucking backdoor build in, who can fucking verify that? We're using Linux, end of discussion.
😓
I was pretty flabbergasted as he's a nice guy and actually really likes windows!
Linux it became.5 -
CIO: what kind of web server do you want for your dev environment? WordPress?
Me: Uhm, Linux centos running apa-
CIO: whoa that's dangerous you need to think of the people who are going to support this.
Me: right...
CIO: we're going to pick something and stick with it.
FML company is just starting to do in house dev. CIO is heavily involved and knows more than I do... My life is a Dilbert comic strip9 -
Spend half the day setting up a dedicated server at work (including getting all the hardware together) and installing CentOS and tweaking around.
For a client? Oh no, there just literally wasn't anything else to do and I didn't want to sit around doing nothing or working on shell scripts AGAIN. (working in support (+ linux server management) and due to the holidays hardly any support requests come in)
*Hmmm, lets install nginx for fun*
"yum install ngi..."
*wait, let's compile from source and make it more fun!*
So yeah, that was my day, I guess.5 -
one day my dad brings home an old blade server from work and a centos distro. we set it up in the garage of our hot Florida house and he gave me his old perl programming books and showed me a few things. I was 12 or 13. that summer I moved my bed to the garage and barely slept as I learned everything I could. I've never looked back.2

Proxmox, i love you but kindly to fuck yourself.
It shouldn't be such a pain to get you up and running.
Let's go for CentOS or Ubuntu server, then.
😤10 -
Got to a client, we are taking over their software dev and IT.
"you're not touching my code ". Listen fuck twit, a robocopy script is not fucking code.
"I wrote a 3500 line code for this company" no fuck twit, you wrote a whole lot of fucking gibberish that looks like someone shat out BASH and it met html along the way. It doesn't compile, it doesn't run, it's a fucking dormant file. You charged people for shit all.
Setting up exchange is also not a big whoop.
Moving them over to CentOS server (he had them on XP still), and writing enough code to qualm my frustration at people.4 -
Fucking cloud providers always trying to steal your shit and spy on your things, fucking prying eyes. That's why i've decided to go back hosting my own private cloud from home. Running on some very energy efficient shit: dual core intel atom cpu (so slow that it can't fucking run windows normally), 16gb of ram, because why the fuck not? and 1tb 2.5"hdd, along with unlimited data - 100/100 Mbit/s internet connection with a server response time less than 95ms just to backup my shitty Iphone selfies and cat pics, host some very important files and regularly back up my contacts. This shit runs CentOS, Nginx, https, bitch! This platform is more trustworthy than your shitty dropbox or whatever other shit they offer you. I can choose whether i back-up my shit from local network or over internetz, Costing me no more than 25€ annually(just to keep the machine on 24/7/365).14

Meet my new toy, Centos7 as of this afternoon (once I get the usb burned and installation done)
She's not much to look at, but she's mine.10 -
It is once again that time of year when we say farewell to our current interns and say hello to a brand new batch.
The two groups overlap for a few days. During this time the old interns show the new interns the ropes, while the mentors silently weep in the lunchroom having realized that nothing that they've said over the last 12 months has had any effect whatsoever.
Some choice quotes:
---
New Intern: It says 'uncaught exception'.
Old Intern: Oh don't worry that will fix itself on production.
---
OI: Did you pull the code?
NI: Yeah, but I have all these weird brackets everywhere... [merge conflict]
OI: Oh yeah that happens sometimes, just delete them.
---
NI: It says "push to master rejected". [we enforce code reviews]
OI: Ohh that means the server is broken. You should tell someone, they have to reboot it.
---
NI: Where did that file save to? [we use ONLY macOS and Linux]
OI: C:\Users\<your name>\My Documents\...
---
OI: You can use either pgAdmin or MySQL Workbench. I like Workbench better but I couldn't get it to work, it kept giving me errors.
---
And of course...
---
OI: No, we don't use Linux. We use CentOS.

I did the math today. Only 35 more years and I can retire.5 -
My first job was actually nontechnical - I was 18 years old and sold premium office furniture for a small store in Munich.
I did code in my free time though (PHP/JS mostly, had a litte browsergame back then - those were the days), so when my boss approached me and asked me whether I liked to take over a coding project, I agreed to the idea.
Little did I know at the time: I was supposed to work with a web agency the boss had contracted to build their online shop. Only that he had no plan or anything, he basically told them "build me an online shop like abc(a major competitor of ours at the time)"
He employed another sales lady who was supposed to manage the shop (that didn't exist yet). In the end, I think 80% of her job was to keep me from killing my boss.
As you can imagine, with this huuuuge amout of planning and these exact visions of what was supposed to be, things went south fast and far. So far that I could visit my fellow flightless birds down in the Penguin's republic of Antarctica and still need to go further.
Well... When my boss started suing the web agency, I was... ahem, asked to take over. Dumb as I was, I did - I was a PHP kid and thought that Magento, being written in PHP, would be easy to master. If you know Magento, you know that was maybe the wrongest thing I ever said.
Fast forward 3 very exhausting months, the thing was online. Not all of it worked yet, but it was online and fairly secure.
I did next to everything myself, administrating the CentOS box the shop was running on, its (own) e-mail server, the web server, all the coding required for the shop (can you spell 12 hour day for 8 hour pay?)
3 further months later, my life basically was a wreck, I dragged myself to work, the only thing I looked forward being the motorcycle ride home. The system worked though.
Mind you, I was still, at the time, working with three major customers, doing deskside support and some admin (Win Server 2008R2 at the time) - because, to quote my boss, "We could not afford a full time developer and we don't need one".
I think i stopped coding in my free time, the one hobby I used to love more than anything on the world, somewhere Decemerish 2012. I dropped out of the open source projects I was in, quit working on my browser game and let everything slide.
I didn't even care to renew the domains and servers for it, I just let it die without notice.
The little free time I had, I spent playing video games and getting drunk/high.
December 2013, 1.5 years on the job, I reached my breaking point and just left, called in sick at least a week per month because I just could not see this fucking place anymore.
I looked for another job outside of ALL of what I did before. No more Magento, no more sales, no more PHP. I didn't have to look for long, despite what I thought of my skills.
In February 2014, I told my boss that I quit. It was still seven months until my new job started, but I wanted him to know early so we could migrate and find a replacement.
The search for said replacement started in June 2014. I had considerably less work in the months before, looks like he got the hint.
In August 2014, my replacement arrived and I got him started.
I found a job, which I am still in, and still happy about after almost half a decade, at a local, medium sized ISP as a software dev and IT security guy. Got a proper training with a certificate and everything now.
My replacement lasted two months, he was external and never really did his job - the site, which until I had quit, had a total of 3 days downtime for 3 YEARS (they were the hoster's fault, not mine), was down for an entire month and he could not even tell why.
HIS followup was kicked after taking two weeks to familiarize himself with the project. Well, I think that two weeks is not even barely enough to familiarize yourself with nearly three years of work, but my boss gave him two days.
In 2016, the shop was replaced with another one. Different shop system, different OS, different CI. I don't know why and I can't say I give a damn.
Almost all the people that worked at the company back with me have left for greener pastures, taking their customers (and revenue) with them.
As for my boss' comments, instructions and lines: THAT might not be safe for work. Or kids. Or humans in general. And there wouldn't be much left if you put it through a language filter...
Moral of the story: No, it's not a bad thing to leave a place if you're mistreated there. Don't mistake loyalty with stupidity!
And, to quote one of my favourite Bands: "Nothing matters when the pain is all but gone" (Tragedy + Time by Rise Against).8 -
Like, seriously, bruh. Some junior have managed to run Notepad++ that consumed a lot of RAM... on our development server... on CentOS... using Wine.15

Should’ve posted this after it happened, but it requires a bit of background anyway.
There’s this guy that oversees our OpenStack environment. My team often make jokes and groan about him in private because he’s so overbearing. A few months back, he had to take us to our data center to show us our new racks, and he kept saying stupid stuff like “you break this and it costs me $30,000” as if he owns everything. He’s just... one of THOSE people. Always speaks in such a condescending way. We make jokes that he is our “best friend”.
Our company is shifting most of our products to the cloud in response to the coronavirus (trying to make it an opportunity for “innovation”). This has involved some structural and responsibility changes in our department, and long story short, I’m now heading the OpenStack environment alongside other projects.
This means going through grueling 1-on-1 meetings with our “best friend”. It’s not too bad, I can be pretty patient with people, so I didn’t mind too much at first. Then a few things happened.
1. He sent a shared folder that he owned containing info related to the environments. Several documents were outdated and incomplete, so I downloaded them, corrected them, and then uploaded the documents to my teams file share, as I was supposed to since we now own the projects.
2. Several files were missing, and when I asked about them, he said “Oh, did you refresh the browser?”. I told him no, that I downloaded them locally and republished them to my teams server, because he was supposed to hand everything off to us at once. He says “Well, silly, how are you going to get updates if you’re looking at them locally?” and kind of chuckles at me like I’m stupid.
3. He insists on training me how to remote into one of the servers to check on cluster space, which in itself is fine. I understand others wanting to make sure things will be done right by the people who come after them. But he tells me to download SuperPutty. I tell him, “oh no, that’s alright. I don’t need putty”. He says “oh cool, what tool do you use for ssh?”. I answer him “Just Git. If I want to I can use a CentOs bash terminal too, because we have WSL installed”. He responds “You can’t ssh through Git”.
I was actually a little shocked. I didn’t know if he was serious or not so I was silent for a few seconds before hesitantly saying “yes you can”. He says “this is news to me” and I so I tell him “every single one of our build jobs fetches code from Git with ssh” and he seemed genuinely shocked and surprised by that.... so then it occurs to me to show him that you can ssh in Powershell and that REALLY blew his mind. He would not shut up about it for several minutes. I was amused until it just got annoying.
Needless to say, my team had been previously teasing me about having to work with him, so they found it hilarious when I told them afterwards.8 -
You know the worst thing about being a freelancer? You're expected to wear every fucking hat and you don't get normal hours.
Over the past few days I have been working with a client of a client attampting to fix his server. He's running CentOS on VMWare and somehow ended up breaking the system.
Upon inspection there was no way to fix his system remotely. It wouldn't even boot in recovery mode. So we've been attempting to recover his data so that we can reinstall CentOS and not have to start completely from scratch.
So for the past 3 days straight I have been remotely logging in to a Debian Live CD and manually sending folders to a FTP server of his. He has somewhere close to 30 sites on this server, and upwards of 1 million files in total.
Yesterday either the system freaked out or he did something, but the entire fucking system stopped responding which forced me to reboot it, reinsert the live CD, reinstall evertything, and re-mount his broken systems drives.
Here we are 3 days in, we're still not done, and I'm getting slightly pissy because if you don't know Linux well enough to fix this shit yourself, you shouldn't be acting as your own sysadmin for 30+ sites.
Also, backups are a thing right? VMWare also has snapshots. I know the extra storage isn't cheap, but it's a hell of a lot cheaper than paying soemone like me $35/hr to go and fix all of your shitty mistakes.2 -
Got pulled out of bed at 6 am again this morning, our VMs were acting up again. Not booting, running extremely slow, high disk usage, etc.
This was the 6 time in as many weeks this happened. And always the marching orders were the same. Find the bug, smash the bug, get it working with the least effort. I've dumped hundreds of hours maintaining this broken shitheap of a system, putting off other duties to keep mission critical stations running.
The culprits? Scummy consultants, Windows 10 1709, and Citrix Studio.
Xen Server performed well enough, likely due to its open source origins and Centos architecture.
Whelp. DasSeahawks was good and pissed. Nothing like getting rousted out of bed after a few scant hours rest for patching the same broken system.
DasSeahawks lost his temper. Things went flying. Exorcists were dispatched and promptly eaten.
Enough. No consultants, no analysts, and no experts touched it. No phone calls, no manuals, not even a google search. Just a very pissed admin and his minion declaring blitzkrieg.
We made our game plan, moved the users out, smoked our cigs, chugged monster, and queued a gnu-metal playlist on spotify.
Then we took a wrecking ball to the whole setup. User docs were saved, all else was rm -r * && shred && summon -u Poseidon -beast Land_Cracken.
Started at 3pm and finished just after midnight. Rebuilt all the vms with RDP, murdered citrix studio (and their bullshit licenses), completely blocked Windows 10 updates after 1607, and load balanced the network.
So what do we get when all the experts are fired? Stabbed lightning. VMs boot in less than 10 seconds, apps open instantly, and server resources are half their previous usage state. My VMs are now the fastest stations in our complex, as they should be.
Next to do: install our mxgpu, script up snapshots and heartbeat, destroy Windows ads/telemetry, and setup PDQ. damn its good to be good!
What i learned --> never allow testing to go to production, consultants will fuck up your shit for a buck, and vendors are half as reliable over consultants. Windows works great without Microsoft, thin clients are overpriced, and getting pissed gets things done.
This my friends, is why admins are assholes.4 -
Progress. The backend is deployed and works on my server. Tomorrow, deploying my fronted code to work with the backend.4
-
I salute all server admins here. I might never understand how you guys get through with all those terminals and debugging and greb and runlevel and all these weird things.
I spent two weeks trying to set up a dev server on CentOS installed on a VM. Just configuring the server took hours of trying to figure out what goes where and in the end I realized that the only thing I did wrong was the runlevel! Which I found out today is actually a thing!!!!
I thank you all for existing. Without you, us web developers would go crazy!2 -
Finally, I can play around with a proper server.
HP ProLiant DL380 G6 = dual 8-core Xenons @ 2.4GHz with 32GB RAM and 12TB / RAID1-0 of WD Purples (we happened to have them for some reason).
Already pissed at HP because they don't support JBOD and already pissed at myself for using CentOS, but other than that, enjoying the hell out of it!
And it's ALL MINE! ... Well, technically it's the org's, but it won't go into production for half a year and I'm the only one with the root access so, for now, it's MINE! 😅13 -
NewLifeNewHope update No.2 / Day 5
My Server Is finally opened and i installed 2x8 TB WDC Harddrives and SATA 128 SSD. I know this server is freaking garbage, but i got this PC for free, and have somewhat good-ish upgrade path, so heres the spec :
-Gigabyte H110m-S2 LGA1151
-Intel i3-6300
-8GB DDR4 single channel RAM
-128 GB SSD
-2x8TB Harddrives
-TP-Link 1000mbps NIC
so the plan is to make this server as the Main Repository -- yes no offsite backup plan for now -- and also i want to make this server as an Email Server and for hosting my company's website. I've already asked for static IP from my ISP and will take effect tommorow.
I need help for choosing the Operating System (i like centOS) for my server. and to setting this Server to work like what i planned but i don't know where to start, Any help and/or References will be great !14 -
I was setting up a small home server running CentOS to my closet and was fighting with a USB Wifi adapter that wouldn't stay "awake". Googled the error messages and nothing...
Decided to about it on the CentOS forums and mentioned (MENTIONED, WASNT THE POINT) CWP (CentOS WebPanel) in my question, an admin came, COMMENTED A LINK TO A FORUM POST THAT TOLD "CWP IS NO WAY LINKED TO CENTOS" AND CLOSED THE QUESTION!
FUUUCKKKKK, i wanted to hit something sooo hard. The admin basically turned my point from A to X.4 -
Sometimes life takes unexpected turns:
I studied mechanical engineering and did some "computer stuff" in my free time, you know, "programming" with Java, toyed around with HTML/CSS/PHP a few years ago, some local server stuff with a raspberry pi, nothing fancy.
Half a year ago i got hired as engineer first but they said they needed an "IT Guy" also.
What i did since then
*Researching, Testing and Planning the introduction of an ERP software
*Planning, coordinating and (partially) setting up a new server for the company (actually two cause redundancy (heavy lifting got done by our IT partner, its not like i suddenly know how to do the entire windows server administration)
*Writing 3 minor tools for some guys in the company in java
*Creating numereous excel vba scripts that make work a lot easier
*doing all the day to day business that comes up when absolutly noone know how to use a pc in the company
*consulting the boss about webshops and websites in general and finding a decent partner
*and some engineering
Did i mentioned that i studied mechanical engineering? I know nothing about all this, or rather, i know enough to know that i know not enough.
My current side project is creating a small intranet, so creating a new VM in Hyper V, setting up some OS (probably slim CentOS), getting a Webserver running and making it somewhat secure. Then i need to create some content, i am very close to just install a mediawiki and call it a day. If i write anything in PHP i fear that i make way to many erros or just reinvent the wheel, on the other hand, i couldnt find anything resembling what i need. I also had to create the front end side, i knew CSS around 2010, there is probably tons of stuff i dont know and i will make so many errors.
This is frustrating, everything i touch feels like i am venturing the beaten path but noone ever showed me the ropes so everything i do feels like childs play. I need an adult. Also the biggest Question remains: What i am?1 -
I've every been a Arch Linux fag. It's my main OS from 5 years. With a small parenthesis of two months of FreeBSD recently, I've used before Arch Kubuntu, Ubuntu, Fedora KDE, OpenSolaris (randomly), CentOs, plus a lot of others distro for tests.
But I've never tested Debian!
So I've installed it on my small server.
Oh... My... God.... It's fantastic. PACMAN >>> apt, but damn it's really stable and out of the box even if minimal. A very surprise. I think it can be my favorite remote Linux for a long time....
But a question rises. Why with a father like Debian... Ubuntu after the 11.04 is such a shame? The last I've tested is the 12.04 I think, but I've hated it, and I hate it even now. (Crash, driver not found, apt problem, very heavy repos and my internet sucks, UNITY, etc...)
Ubuntu, what happened to you ...? With Kubuntu 8 you were such a good guy...4 -
Helping a client to update their 5 years old payment system to support the new mobile PayPal library via Braintree.
Found out you need to install a server SDK that requires PHP 5.4.
Installed and then realised the server is still on PHP 5.3 (CentOS 6).
Panic.
Told my client that they require a new server just so that I don’t need to manage the PHP 5.3 to 5.4 update on their live server and I can install Node to use the Braintree NodeJS SDK 😇.
Feels like heaven.2 -
So I'm trying out docker and see how I can make use of it, current setup:
1. Ubuntu on VM and Mac for Asp.Net core development
2. Windiws for MS only stuff like SQL Server
3. Ubuntu Server on VM and is running docker images: MS image for SQL and Ms image for dinner core.
What I did so far one script which will handle updating SQL Server database on windows with the changes done on docker SQL image
Then publish website from Mac or Ubuntu to docker image. I have yet to find a way to execute scripts remotely on a docker image using bash script from a remote
What should I do next? And for home setup go for Ubuntu server or CentOS? Any recommended packages for server administration? Workflow ..etc.?2 -
So I got access to a new Centos server. I had to install applications like Mysql, tomcat etc. The install was easy but configuration to be done were fucking headache. Admin guys were such Assholes that they dint care much to help. It took me 3 days to finally sort out and got things running. Yay! I believe I learnt a lot about Linux. Thank you Admin for being such an asshole✌️1

What the fuck is this piece of shit called Ubuntu? I was writing an automation tool on my local PC (ArchLinux) in c++ 17 (c++1z or whatever). Finished it today. Working and compiling so everything is fine. Went to my server, git clone, make.
Okay some errors because I havent installed my networking libs yet. So I installed them.
Make.
Error because I was using a c++ feature only available in c++ 17. But wtf. I told g++ I wanted to compile with c++ 17 support. I mean... On arch it compiled fine. On centOS it at least told me that it doesn't know c++1z (it was some really old centOS). BUT JUST TELLING ME ITS BECAUSE I SUCK AT PROGRAMMING?? THAT IS SO NOT OKAY. MY CODE IS LEGIT ISO C++ 17. FUCK UBUNTU. Installing Arch on my server now because I can't handle this shit anymore...16 -
Discovered this dumb backdoor into http://tutorialspoint.com/codinggro... months ago (June 2019). It's in Project>Compilation Options
It lets you execute any command on their server. I found a lot out:
The system is Red Hat based (Fedora/CentOS/RHEL)
It uses Linux kernel 3.20
It has 251GB of RAM
It has an 800GB HDD
Its IP is 172.17.0.2
Its main username is cg
It uses systemd init8 -
Trying to install Centos7 onto my proliant g6, red screen, try a fix, red screen, try another fix, red screen, finally find a fix that seems like it is the exact problem, screen dies can't see bios... god damnit.18

TL:DR linux newbie, looking for advice/links (skip to bottom for questions)
!rant
After i had been looking for a job for quite some time, a couple of months ago i got hired by "smaller" company doing web stuff. So far it have been a great place, good colleagues, and overall just having a great time!.
They seem to value me alot, so that's great!.
Anyway, yesterday i got called into a meeting - and got told they wanted me to start learning "Server stuff (linux)". That got me quite excited, because it always was something i wanted to learn - but never really got around to doing.
But i never touched a linux installation before, so i'm really on ground zero - but im not afraid, i'm a quick learner and quite efficient at googling :)
I figured i would ask here, since other people here always seems to be happy to help other people out.
So far i have manage to setup a server, install various stuff (php, mysql and so on) and done setup a couple of domains/subdomains on my server. Also got a vestacpinstallation working - so overall im quite happy so far.
I figured maybe somebody had some good links/advice for a linux newbie :).
* Performance/Security, will obviously be a big focus - anything i should look at? - any must look at?
* Monitoring tools, how do i monitor various websites running on my server? Here i'm thinking bandwitch, cpu/ram usage and so on pr site basis.
* Any other stuff i should be looking at?
Little about what the server will/should be running :)
* Centos
* vestacp
* WordPress installations only (e-commerce mainly)
* PHP 7 / MySQL / phpmyadmin5 -
It was about 2:30am.. The darkness had been dominating the outside for a while, and I was having issues with my partitions on my CentOS server. Yup that's correct. I think.
I really wanted to go to bed. Last thing I had to do, was re-allocate some space from centos-home to centos-root. But I fucked up, of course I did.
After about half an hour of making food and trying different stuff to solve the "Can't read superblock error" error, I found an answer that just lead to "Can't read secondary superblock error, sorry".
At least they apologize now lol.
I ended up trashing the centos-home volume (is volume and partition the same ?) and just smashing it all onto centos-root. I lost some data, but screw that, stuff is working and I'm not going to bed.
Yeah, stuff is working. I hope. No errors encountered yet.
Moral of the story: Home partition isn't needed and it's okay to kill it1 -
My group set up a Linux Dev server. We got hacked by Chinese hackers. We set it up again but even more secure with only people inside the uni can access it. We got hacked again.Turns out one of the modules in a container was using an outdated CentOS version. P.S The malicious file on the server was called kk.love.1
-
why.... why on this freaking earth would you go an enable Hypervision on me?
seriously #Windows, you are starting to drive me over the edge.
theres nothing like powering up a centos server - yea not even a DE, (that had no issues yesterday) and getting "VT-x is not available".

Any recommended reading material for someone deploying a go web application for the first time?
I am trying to see if I can deploy a go app into one of my institution's test linux servers. I would have one of the technicians create the server, so It doesn't really matter what it is, but lets say for argument's sake that the servers in question are either an ubuntu server or a red hat/centos server. Any recommendations before I dive in?6 -
I've been wondering about renting a new VPS to get all my websites sorted out again. I am tired of shared hosting and I am able to manage it as I've been in the past.
With so many great people here, I was trying to put together some of the best practices and resources on how to handle the setup and configuration of a new machine, and I hope this post may help someone while trying to gather the best know-how in the comments. Don't be scared by the lengthy post, please.
The following tips are mainly from @Condor, @Noob, @Linuxxx and some other were gathered in the webz. Thanks for @Linux for recommending me Vultr VPS. I would appreciate further feedback from the community on how to improve this and/or change anything that may seem incorrect or should be done in better way.
1. Clean install CentOS 7 or Ubuntu (I am used to both, do you recommend more? Why?)
2. Install existing updates
3. Disable root login
4. Disable password for ssh
5. RSA key login with strong passwords/passphrases
6. Set correct locale and correct timezone (if different from default)
7. Close all ports
8. Disable and delete unneeded services
9. Install CSF
10. Install knockd (is it worth it at all? Isn't it security through obscurity?)
11. Install Fail2Ban (worth to install side by side with CSF? If not, why?)
12. Install ufw firewall (or keep with CSF/Fail2Ban? Why?)
13. Install rkhunter
14. Install anti-rootkit software (side by side with rkhunter?) (SELinux or AppArmor? Why?)
15. Enable Nginx/CSF rate limiting against SYN attacks
16. For a server to be public, is an IDS / IPS recommended? If so, which and why?
17. Log Injection Attacks in Application Layer - I should keep an eye on them. Is there any tool to help scanning?
If I want to have a server that serves multiple websites, would you add/change anything to the following?
18. Install Docker and manage separate instances with a Dockerfile powered base image with the following? Or should I keep all the servers in one main installation?
19. Install Nginx
20. Install PHP-FPM
21. Install PHP7
22. Install Memcached
23. Install MariaDB
24. Install phpMyAdmin (On specific port? Any recommendations here?)
I am sorry if this is somewhat lengthy, but I hope it may get better and be a good starting guide for a new server setup (eventually become a repo). Feel free to contribute in the comments.24 -
What linux OS would you recommend for a little home server/nas? I guess I want something debian based but CentOS is also apparently good8

Went through 60 python packages to see which fails installing on the serve. Took hrs as I have no terminal access but just via jenkins pipeline. So "edit/gitpush requirements.txt and wait" many times. Eventually looped them 1 by 1 in shell. By end of day got the list that installs.
Finally sent the whole list....with confidence
-Takes full 10 mins & Fails......
(panic mode starts)
+Changed the sequence = fails, somewhere else
+1 by 1 again = installs.....
+few random without the culprit =works
+again, whole list = fails, somewhere else

Im setting up a cPanel Dev server for the very first time. I need to install CentOS and will be doing it through a USB. I was able to burn the iso but it wont boot :( How do I boot into the installer? :((2

How much ram do you generally need in a Linux server? I'm already using 70% out of 2GB on my LAMP stack, and I'm planning to deploy my website prototype to show off in interviews next year. Is 8-16GB of EEC RAM a better option for future proofing? The only thing holding me back is I don't plan to make money on this server in the immediate future so I'm trying to weigh the pros and cons. 🤔
This CentOS server runs on CLI only so the GUI isn't a factor. Eventually I'll have it host Java Spring API's which will easily take up what RAM I have left. On top of that I have 10 db on mySQL so that's another likely culprit.7 -
Just bought Intel NUC and installed CentOS on it. Mounted NFS from my NAS. Installed docker, downloaded factorio image and started server. Now I have my own game server lol.

I love python, when it works.
Im really new and retarded at the language, but i managed to make a small useful program for my dad.
It works perfectly on Windows, yay.
It needs to run on a CentOS server, and for some reason, smtplib wont allow me to log into my gmail when i run it on CentOS :(
And yes, i did install all packages with pip, and i do run it with Python3, same version as i wrote it in.
I also added that nifty shebang that doesnt appear to do shet for me xD3 -
"Okay I'll try Centos 7 on my personal server (kinda old hardware).. Wired network does not work with my eth card? Centos 6 it is then.. " what is your favourite Linux server os?2

My current "file/media server" is a crappy old falling apart windows box with a stupid mismash of internal and external drives with no redundancy. That sucks for a number of reasons, so planning on dropping around a grand or so (including drives) on doing it properly.
Space requirement would be around 20TB-ish of usable space, with 1 disk's worth of redundancy. That can include a newish 5TB drive I have lying around however. Would also run either Plex / Jellyfin, so some horsepower for transcoding would be nice (but no need for more than a single 1080 stream at once.) 24/7 operation, so don't want anything too power hungry.
Current (loose) thinking on the hardware side is an AM4 board and a reasonably low end CPU, 3x8TB WD golds. Software side, probably CentOS, then mergerfs + snapraid. Anyone got any insight as to other options? Hardware not my speciality in particular, so open to suggestions.14 -
Holy fucking shit, I hate ubuntu SO much.
So what it happened..
I was tryin to set up an Ubuntu server on my machine using virtual box, and I know what you are thinking, "VirtualBox?" yeah its the only machine I had lying around and it had windows and I didn't wanna re-format its hard drive.
So Here how it goes...
Install went fine.. But when I was trying to manage multiple network interfaces, it was Terrible & pain in the ASS 😡...
So initially I needed 2 network interfaces, one for NAT adapter and another Host-only interface for SSH and stuff.. so I made changes in virtualbox settings and rebooted the VM. and it stuck on "a start job is running for wait for network to be configured" I was like okayy and removed host-only adapter and rebooted, it booted fine :/ then I tried combo of bridged adapter with my Ethernet and a host-only adapter, and what? it booted finally! but this wasn't an optimal solution because it had and IP address within subnet of other devices with my router and half the bandwidth (like 50mbps or something).. I reverted back to NAT network & I checked with ifconfig and it STILL didn't had an IP address assigned to it for Host-only adapter!! FFS I deleted the VM and reinstalled the whole thing again but this time both interfaces attached..
after installing it stuck on same shit again :'(
"a start job is running for wait for network to be configured"... FUCK!
after about an hour of troubleshooting and trying different configurations, I still couldn't get it to work.. I never had such problems with centOS.
Fuck you ubuntu.. fuck you in the ass7 -
What are types of load issues occurs in a Linux (Cent os) server and it is troubleshooting methods???15
