Why the need for another 'Installing Moodle' guide? Two reasons, Systemd and SELinux.
The steps are presented as a Bash script, which may be run on a virgin system, installing a complete working Moodle stack in one go, including enforcing SELinux.
In addition to the absolute basics it also includes adding ClamAV virus for file uploads and Memcached for sessions and 'MUC'.
It does not cover any extras you will need to get your site up to production, e.g. securing your database or updating your virus definitions automatically. Neither does it do any extra PHP configuration (upload limits, execution time etc.) or any extra complexities that might be desirable. For all of this you should goto docs.moodle.org.
