apiscp-webapp-discourse VS almalinux-deploy

For my professional stuff I bought ApisCP and installed it on a $27/month SoYouStart server.

You could try ApisCP : https://apiscp.com/

ApisCP can do this :) It has a few one-click apps, and Discourse is among them.

Some examples of these approaches include ARA builds, which is a flask app using Passenger; Discourse using ProxyPass to a Unicorn instance without Passenger (also available as a one-click), and Ghost (also available as a one-click) using Node with Passenger.

Running another 8.x? Move to AlmaLinux using almalinux-deploy.

I mention that because you had to be at CentOS 8 latest, and since CentOS is now a stinkin pile of nothingness, there are adjustments path wise to point at Alma's capture of that in order to prep to make the jump. I think all that is documented here: https://github.com/AlmaLinux/almalinux-deploy

You can also convert an Oracle Cloud to Alma or Rocky then install ApisCP. If you do, append -s has_low_memory=1 to the installer.

If going with Oracle Linux it's necessary to convert to Alma or Rocky before installing the 30-day trial. This also doubles as a great hack for a free 1 GB DNS-only server.

Just follow those steps to migrate centos to almalinux: https://github.com/AlmaLinux/almalinux-deploy

I understand from here that it is recommended to update to CentOS 8.5. I have carefully inspected the recommended approaches from the README and this issue and attempted to cobble together something that I believe should work but I am facing some issues.

I used the Almalinux deploy script to switch to Alma.

A version of our Open Source hosting control panel (BlueOnyx 5210R) was initially shipped with CentOS 8 as base OS before we switched the installation media to AlmaLinux. Those that were still running CentOS 8 were informed via the GUI to convert to AlmaLinux by running the AlmaLinux conversion script that we had bundled with an update or ours.

Thanks for the questions. We already have several migration options. If you're currently on CentOS 8 or any other EL8 you can use this: https://github.com/AlmaLinux/almalinux-deploy. If you are on CentOS 7.x you can use our ELevate project: https://almalinux.org/elevate.
