New OS - which to use?

morrow95

Currently using centos 7 - two different VMs... one with whm/cpanel and our sites and the other dedicated to MariaDB and a remote connection through WHM for it.  This is a production environment with very high traffic.

It looks like Almalinux 9 would be the best bet, but I am just now seeing it doesn't support mod_lsapi which considering our traffic and amount of hits comes in very handy.

I see Almalinux 8 DOES support mod_lsapi, but the EOL support with cpanel/whm looks to end in '29 whereas Almalinux 9 is '32.

I want to stay away from Cloudlinux for various reasons as well as the additional costs involved.

Not sure if Rockylinux 9 supports mod_lsapi or not - can't seem to find that information.  I was leaning away from it as well since it isn't community and might be sold or have other things happen in the future which might pose a problem for us if using it.

What is the recommendation?  Pros/cons?  Would like to get this taken care of in the next month or so as our Centos 7 is already stale with the latest whm/cpanel versions.

    I would do Alma 8. It is well supported already and you will have a seamless way to upgrade to further versions later on.

    Thanks for the reply Andrew - just to confirm - 8 supports mod_lsapi right?  Coming from CentoOS 7 might little research so far kind of comfirms this would be the most straightforward OS to go for... other than not being the 'latest' offered.

    We had a for the most part painless migration to Almalinux 8 / CloudLinux 8 for about 500 companies
    lsapi is supported by default in EA4


    It is important to note that only from the 2024 LTS will have official Alma and Rocky Linux 9 support
    The other ones Stable, Release, Current are supported but if you want to run LTS it is something to keep note of.

    Also the 9 series does not allow PHP older than 8.0 which might or not be a obstacle in your case.

    I always make it a habit of updating any code for php so have been running php 8 since it became available.  lspai was the main thing I found that would pose a problem - lots of php pages that are hit very frequently so it makes a huge impact on performance for us.

    I have this odd feeling that shortly after I make this change that almalinux 9 is going to be fully supported and have lsapi compatibility.  I kind of remember something similar happening with our last os update - we had to use centos 7 instead of 8.

    Current plan is to spin up a new vm and start from scratch and get everything copied over and setup.  Once that is done I can shutdown the database vm and export/import it over.  Seems to be the safest method and while I did run into a few problems last time it got all sorted out.
