Transition apache_high_php_limits: -> nginx_high_php_limits: False/True [for Nextcloud, WordPress, Moodle]

[holta]

1. Does IIAB's apache_high_php_limits: False/True (as set in /etc/iiab/local_vars.yml) work with NGINX today?

2. If not, what's needed to get it working? This is needed by schools requiring intensive usage of WordPress, Nextcloud, Moodle etc.

3. Should the variable be renamed to high_php_limits to serve both Apache and NGINX?

1. no, but there are articles on optimizing php in nginx. also, except for wordpress, the php apps are still served by apache.
2. how do you know it's needed by nginx, that the performance profile is the same as apache? Is it an apache setting or a php setting?
3. don't think we know yet

Is it an apache setting or a php setting?

It's set in /etc/php/7.2/apache2/php.ini (on Ubuntu 18.04) or /etc/php/7.3/apache2/php.ini (on Raspbian Buster) as explained here: https://github.com/iiab/iiab/blob/master/roles/httpd/tasks/enable.yml#L1-L14

Can someone (@ericnitschke?) make any kind of NGINX recommendation here (for larger schools & computer labs) even if worst case we have to revise that later, based on field experience?

Nextcloud isn't yet natively served by NGINX, but FYI to help @m-anish & all of us navigate this...a fresh install of IIAB (on Ubuntu 19.10) shows:

Security & setup warnings
...
The PHP memory limit is below the recommended value of 512MB.

You can get to this page (http://10.8.0.46/nextcloud/index.php/settings/admin/overview) by clicking http://10.8.0.46/nextcloud > (circle containing 'A' in top-right) > Settings (in dropdown) > Overview (in Administration section, in left panel).

Variable apache_high_php_limits: False/True has been replaced by nginx_high_php_limits: False/True
