Apache Check is an little PHP script that checks Apache HTTP Server (or Nginx) configuration on a LAMP server (Linux-Apache-Mysql-PHP) or LEMP server (Linux-Nginx-Mysql-PHP).
The script looks at the Apache or Nginx config files, its processes, the memory usage, the CPU and disk IO. It also looks at PHP-FPM and MySql (or MariaDB) resources usage to guess overall usages in various situations. It does some checks on parameter values, indicates critical problems, give warnings and recommendations. You apply the recommendations of this software at your own risk, and you are solely responsible for the consequences of modifications you may apply to your system.
This script try to avoid dependencies, but as it has to look at processes and files descriptors in /proc, it has to be executed as root on the server.
First download the last version (2.0.2) of the script here, uncompress it (for example with unzip apachecheck_v2.0.2.zip), and copy the PHP script on your server.
If PHP CLI (Command Line Interpreter) is not installed, install it (for example apt-get install php-cli on Debian based systems).
As root user, execute the script : php apachecheck.php
you should have this kind of result :
root@Server:~# php apachecheck.php
