CentOS Stream suitability as a production webserver
by Jamie Burchell 25 Jan '21

25 Jan '21

Hello I've recently discovered the announcement regarding the change in direction for the CentOS project and I imagine like many others, I'm confused and concerned about what this means moving forward. I work for a small web development agency and we offer hosting as part of our package to clients who need it. We have many CentOS 7 web servers (DigitalOcean droplets) (LAMP/LEMP) that I look after and today I'm thankful I have only migrated one of those to CentOS 8, given the recent announcement about its curtailed EOL. I literally just went to the Wiki today to confirm the EOL date for EL7 and boy am I glad I spotted it. Given we are not developing drivers or applications (other than websites and web applications), is the change a non-issue for my use-case? I've seen it written that CentOS Stream is the "development version" of RHEL but also that we shouldn't have considered RHEL to be the beta for CentOS. Others have said to think of CentOS more like RHEL RC-1. I just don't know how the stability will compare and we have historically always chosen CentOS for its stability (and of course price). Sure, I could migrate to Ubuntu (I use this locally in WSL), but I've become somewhat "comfy slippers" with CentOS and have built our setup around it (including custom ansible scripts etc) and don't want to change everything unncessarily. Of course, a lot of this is somewhat dependent on what DigitalOcean will decide to provide image wise moving forward. I'm sorry if this has already been answered, I spent a good few hours reading through the respective threads in the devel list and ended up more confused than I started. Cheers, Jamie

simple http server grab data posted and send to another server - slightly off topic
by Jerry Geis 22 Jan '21

22 Jan '21

Hi All, anyone know how to make a "simple" http server (python -m SimpleHTTPServer 8000) type of stuff - but simply take the incoming data, (should be real small) and when received - send that to a different server . This is different than "redirect" as that is the issue. The device does not understand the redirect response that is happening now. So I was looking for a way to "consume" the post - then re-send the post. It has to be independent of httpd as that is in use. CentOS 7 is my platform. Thanks Jerry

KVM support on RT Kernerl
by Danishka Navin 21 Jan '21

21 Jan '21

Hi, I have deployed CentOS 7.6 and then installed RT kernel. Later KVM installed on the same box. I noticed that KVM module was not loaded and then switched to the generic kernel. KVM module was loaded in the generic kernel. Is this a known issue? I would like to use KVM with RT kernel. Regards, -- Danishka Navin

Compiling Qt applications in docker
by H 21 Jan '21

21 Jan '21

I am working on compiling an application using Qt and am a newbie. I already have Qt on my CentOS 7 system but this application requires a later version of Qt not available for C 7. It also requires postgreSQL libraries and I am using the latest version of that, ie pgsql 13. I have successfully compiled it in a docker environment and I can launch it on the desktop. I have, however, not tested it against postgreSQL on my computer - yet. I do not want to run it in docker though but on my "regular" computer outside docker, as well as be able to move it to other computers I have. I am only using docker as a sandbox while working on compiling etc. I am not sure how I should set it up - outside docker - so that the Qt libraries it needs do not foul up the rest of my system but are only seen by this particular application. Can anyone offer a suggestion? Should the compiled application eventually reside in its own directory under /usr/local/bin and where should the Qt libraries be? In the same directory as the app? If not, where should they be placed? I tried to compile it to use the Qt libraries statically linked but the app does not run that way in docker but crashes with a segmentation fault. Suggestions/best practices appreciated!
