Unable to update WordPress due to incorrect file permission

I am getting error while updating plugin. This is Oracle Linux Arm Ampere instance.

An error occurred while updating Akismet Anti-Spam: Could not create directory.

I have applied following permission on files and folders.

sudo chown -R nginx:nginx /var/www/mysite/html
sudo find /var/www/mysite/html -type d -exec chmod 755 {} \;
sudo find /var/www/mysite/html -type f -exec chmod 644 {} \;

I have another WordPress site on VirMach VPS with same permission and there it updates fine. Here's result of ls -l

Site Health in WordPress says:

Shows whether WordPress is able to write to the directories it needs access to.

The main WordPress directory    Not writable
The wp-content directory    Not writable
The uploads directory   Not writable
The plugins directory   Not writable
The themes directory    Not writable

But the other site on VirMach VPS says these folders are writeable.

SELinux is disabled.

    Before someone who actually knows anything offers a solution (and/or corrects me), did you try re-setting the permissions a bit higher up the directory hierarchy (provided that doesn't affect security in a bad way)?

    How's Akismet working for you - beside the update problem?

    Ok after much trial and error I managed to fix the issue. I compared www.conf of both VPS and noticed the following:

    Debian 11 on VirMach
    sudo nano /etc/php/8.1/fpm/pool.d/www.conf
    user = www-data
    group = www-data

    Oracle Linux 8 on Oracle Cloud
    sudo nano /etc/php-fpm.d/www.conf
    user = apache
    group = apache

    Aha so the user is actually apache and not nginx as I thought. So running following command fixed the issue.

    sudo chown -R apache:apache /var/www/mysite/html

    Why not a standard user “www-data” or “website?”

    Edit:
    Based on response below,
    Maybe CentOsWebPanel might be a better fit. Debian I would have recommended Webinoly - best wishes

    Because apache is defined in Oracle Linux 8 in phpfpm config. I can try to change it to www-data but it may require some extra work fiddling with permission as I am a Linux noob.

    Are you alilet on LET? Questions seem the same on both forums.
    You have mentioned your Server OS as Debian11. Here you mention Oracle Linux 8.
    What OS exactly are you using or planning to use?

    Yeah. Debian 11 is VirMach VPS. Oracle Linux is Arm Ampere for which I posted this issue.

    I had suggested CWP (Centos web panel) which will not work afaik. See if Ajenti works. If your end goal is WordPress, then you should be focusing on WP management, not server admin :-)
    See if any of these projects have an arm equivalent

  • Oracle Linux is similar to Fedora, FWIW - Some (Most?) tutorials for Fedora should work on Oracle Linux as well.

    Failing that, Ubuntu is available for ARM instances on Oracle Cloud.

    Cheap dedis are my drug, and I'm too far gone to turn back.
