    Wow that was fast. It's probably why I naturally lean to AlmaLinux due the known past history with CloudLinux. They've now also announced Alma are for Enterprise paid support which is another good sign to their intentions https://tuxcare.com/tuxcare-launche...and-compliance-capabilities-for-almalinux-os/

    Same goes for Rocky Linux. If anyone wants Enterprise paid support. You can get it.
    CIQ is the company of Gregory Kurtzer. Same person founded Rocky Linux and CentOS back in the days.

    Why should you purchase "official" support from a company that forked/cloned software?
    Then you could also look into Red Hat support and services from the source itself.

    Problem is that if you want services certified. For example for mission critical services.
    Really everything has to be certified, including the hardware.

    To my knowledge, forks are not certified. Binary compatible does not exist in insurance land.
    You can get Enterprise Linux (EL) certified hardware only with Red Hat and/or Oracle certified. To my knowledge. But I did not investigate that further because it is not relevant to me.

    Based on that fact, Oracle Linux is the only fork and EL binary compatible that is fully certifiable.

    Why run Red Hat's Cockpit on Ubuntu?
    Are there any special reasons why you are running Ubuntu?

    It's like HetrixTool but self hosted and free.
    I'd like to monitor the server with nice looking graphs.

    Main reason is hardware compatibility, like CMM stable is only for Centos7.
    Some other server I got is ARM based and it does work with Debain and Ubuntu only.

    Yeah ARM based servers is definitely something Ubuntu has better handling of right now. EL8/EL9 is alot better for ARM than EL7 so game will be changing - Centmin Mod on ARM is something to look at once EL8+ is settled.

    To my knowledge. Cockpit is a browser-based administration tool for Linux.
    Are we talking about the same Cockpit here?
    CentOS 7 and EL7 are ARM64 compatible.
    Do you mean that CMM is only for X64? Because that is right.
    Or are you using ARM32.

    Yes and I mean this:
    https://cockpit-project.org/

    It has realtime stats and graphs.
    Hetzner only offer Debian and Ubuntu Install for ARM servers.

    Yeah, originally that road block was in early days of CentOS 7 ARM64 YUM repos for MariaDB <10.3 and 3rd party wasn't at parity at the time. It's a lot better now but no where near as good as EL8+ ARM64 for 3rd party and MariaDB >10.3

    So you use cockpit not for management but for statistics? Interesting and nice to see.
    About your matrix rx server.

    You are using Ubuntu with your already known stack based on CMM?
    In other words you copied the CMM configuration files (Nginx, PHP, Mysql) to your Ubuntu server?

    Some nice-to-have features of it that I mostly use are:
    - Real-time statistics and graphs
    - Be able to dig to old statistics/graphs
    - So much easier to create and modify users, add public key, view login history, etc.
    - So much easier to read server logs
    - Access to terminal without any SSH client needed
    - It has so much to offer
    I basically created my own LEMP stack, depends on what needed for the web app.
    There was no source compile, but all were installed from default Ubuntu LTS repository or from deb.sury.org (for the latest PHP).
    Nginx mainline, PHP 8.x, MariaDB 10.6, Redis, ElasticSearch... very easy to update, and very stable.
    No but I use this as base for my Nginx config:
    GitHub - h5bp/server-configs-nginx: Nginx HTTP server boilerplate configs

    What about performances: h5bp/server-configs-nginx v.s. centminmod - Overview ?

    Btw https://deb.sury.org/ is non LTS. Upstream release, directly from the the source.

    I will do a benchmark later using loader.io, but last time I did it, CMM Nginx was quicker to respond by roughly 5-8%.

    Thanks for the upcoming benchmark.

    Question. Why did you choose a relatively weak Ampere Altra Q80-30 based server?
    Based on the responses below. Per core, the processor is comparable to an entry-level, consumer x64 CPU, of 2019.

    Correct me if I'm wrong, but Nginx, PHP, and MySQL are multi-threaded applications/services.
    And that ARM has 80 CPU cores; with a very busy XF2 board, it's flawless now with that ARM-based server.

    I can see a significant drop in pageload (non-cached) stats after we switch to that server from CMM-based CentOS 7.

    You are (seems to be) shuffling data. First you state that it is "quicker" with CMM "by roughly 5-8%", and thus the old server (the new server is not compatible with CMM). Then you come up with contradictory data and "a significant drop in pageload". Which is true? Finally, the benchmarks per core of the Ampere Altra Q80-30 CPU is not my benchmark nor research. See hyperlink for more info.

    That comparison I did was on a different but identical-spec Vultr test server.
    Ubuntu LTS Nginx vs. CentOS 7 CMM Nginx, and the previous test I did was just for Nginx alone (no PHP or MySQL involved).

    Nothing to do with our previous and current live/production servers.
    But I think the ARM-based server is faster compared to the previous Xeon server.

    I will find some time later and do a complete comparison of:
    Ubuntu 22.04 LTS / Nginx / PHP / MariaDB
    versus
    CentOS 7 with / CMM / Nginx / PHP / MariaDB

    Could be. Several users (see above) reports a relatively weak core. Perhaps that is why there are 80 cores in the Ampere Altra Q80-30 CPU. Then on that front, you can easily compensate.
    So that was not written there. That's probably why I was confused. Please fully describe the subject next time. That avoids possible confusion. Thanks buddy;).
    Now let's get back on topic. CentOS, EOL and the legacy.
