Unsolved Fedora Server for production use?
-
I need to run RabbitMQ and Erlang and planned to deploy CentOS, but EPEL is totally outdated when it comes to RabbitMQ: Packages are 7-9 months behind the official releases. There doesn't seem to be another RPM repository for RabbitMQ. Sure, I could compile everything from source or use the RPM packages provided by rabbitmq.com, but I always try to stick to maintained packages due to updates.
Luckily, Fedora (RedHat based) has up to date packages, same for Ubuntu (Debian based).
Top-most requirements:
- Up to date RabbitMQ packages
- Reliabilty / stability
- Small disk and memory footprint
Question: Is Fedora something you would use for a production system?
UPDATE: It looks like that Fedora doesn't match my (super) low memory footprint requirement. Sadly, I don't have time to investigate any further here and will fall back to Ubuntu.
PS: Thanks for tagging the thread, Scott.

Yes, definitely. It would not be my first choice for most systems, I'd stick to CentOS, but it is very stable and solid on its own and no reason not to run it when warranted.

Great, thanks. Was exactly what I thought: Not my first choice, but still a good one.
Just thought about another requirement (mono and webserver for ASP.NET), but this should do fine too:

Interesting: Fedora 25 starts to panic with RAM < 512MB at the beginning of the kernel init phase, even in text mode. Just had a look at the manual which clearly says that Fedora requires 1GB of RAM.
Looks like I'm out of luck and have to stick to Ubuntu / Debian.

That's super weird. I've not tried to compress it that far, but that's ridiculous.

Yeah, seems to be a hard constraint of some sort. They are probably loading tons of hard compiled kernel drivers. Maybe some weird initrd setup, large ramdisks (I don't think so, that's more in the userland area). Who knows

Just googled for "fedora 256MB" and found this: http://forums.fedoraforum.org/showthread.php?t=291559
Looks like there are workarounds, but "should work" is not what I'm looking for.

That's what testing is for

It's only a memory check, not an actual technical issue. I would go ahead with it.

A check in the kernel phase? It happens right after choosing the kernel command line.

It has to be in the installer.

That's what I thought. So the kernel panic is likely caused by something else.

Raised the VMs memory to 1GB, did a text mode install, as suggested.
But the "blank" system alone is already using 256MB of RAM. There's some kind of management webserver installed and lots of other processes running in the background.
-
This is going to be one of these days...
Currently installing Ubuntu 16.04.1 using the ~700MB server ISO. It won't find the installation source mount point when I try to run the machine with just 256MB...
Works fine with 512MB.

Cockpit. You have to "leanify" Fedora.

Why an old version? Current has the best chance of success and for production use, support is critical so that should rule out the older versions that are limited support.

Because it's the current stable LTS release.

Ubuntu 16.04.1, not yet updated. Looks way better.

That's not a reason. LTS is not the fully supported product from Canonical. There is nothing current about 16.04. 16.10 is the only fully supported Ubuntu product today. If this is for production, you need support. Don't skip support just to get an LTS moniker. LTS is three letters, it is not a support agreement.

You're right. Just had the ISO here and didn't thought about the 16.10 release.
