have i missed something?
Thanks in advance for any help.

Hi,

I suggest not installing on CentOS 8 purely because it goes EOL on 31.12.2021 - so in about 11 days your system will no longer be supported or get updates.

I personally recommend using Debian 10 (Debian 11 package of Gitlab isn’t out yet, but you can install the Debian 10 one without problems), or utilise Ubuntu 20.04 LTS for Gitlab. If you really need a RHEL clone like CentOS, then I recommend Rocky Linux but you might have to jump through some extra hoops to get Gitlab installed (I haven’t tried to install on Rocky personally but it should work) - hence my previous recommendations for Debian/Ubuntu since that just works.

Good to know about CentOS going EOL in 11 days… i apparently didn’t get the memo, and my whole domain runs CentOS… that is a lot of migration to do, with the risk of accidentally formatting my data, and no budget for a backup server…
now i have to learn the in’s and out’s of a completely new distro.

anyway, thanks! i will look into Debian.

If you stick with Rocky Linux 8, then it’s just the same as RHEL/CentOS 8 so everything you know up until now will work on Rocky in just the same way. If you are willing to learn something new, then setting up Debian/Ubuntu is not so bad. Linux is Linux pretty much, each distro has their own way of doing things, but I feel that it’s great to have experience of a few distros. By default Debian doesn’t have a firewall set up like Rocky 8/RHEL 8/CentOS 8 has firewalld running by default. Ubuntu also doesn’t, but ufw is installed and can be configured.

Providing Rocky gets detected as EL8, then Gitlab will install without any extra steps to tell it that it’s RHEL8, or something. There is info in the documentation about it, so if you want to get something up and running in a familiar environment like CentOS, then Rocky would be the way to go. We can help out if their are any problems. I have a minimal Rocky instance, but can easily set one up with Gitlab CPU/RAM specs if you get stuck and then help you out with the steps needed to get it running.

i may just switch to debian. my CNC machine runs Debian (linuxcnc.org), so i at least have “some” experience with it. just a PITA to get all the services back up and running, and remembering how i did it…
hopefully on my main server, i can just use the established /home folder as is, as it would be a shame to lose all my data there. i know i can install under CentOS without affecting the /home, but haven’t tried it on Debian.
Fortunately, i even have Debian 10 on a flash drive from my CNC machine OS install.

Yes, you can mount home and use it under Debian without any issues. I normally just copy the data and install to a new machine, but it is possible to re-use a partition and not format it.

The only thing you will need to do is make sure if creating users for a home directory that already exists is to reset permissions later if the uid/gid changed when adding the user. Or alternatively, make a note of the existing uid/gid of the user’s home directory and pass this when creating the new user.
