Optimize MySQL & Apache on cPanel/WHM server
Optimize MySQL & Apache on cPanel/WHM server
On this optimization process, we will go over the Apache core configuration and modules that are part of Apache core. We think that with the correct settings of Apache and MySQL you can get excellent results and the correct level of resource use without installing third-party proxy and cache modules. So let’s start,
Apache & PHP
In the first stage we run the Easy Apache and selected the following:
- Apache Version 2.4+
PHP Version 5.6+
In step 5 “Exhaustive Options List” select
– Deflate
– Expires
– MPM Worker
After Easy Apache finished go to your WHM » Service Configuration » Apache Configuration » “Global Configuration” and set the values by the level of resources available on your server.
Apache Directive (From 2GB memory or less and to 12GB+ memory) StartServers 4 8 16 MinSpareServers 4 8 16 MaxSpareServers 8 16 32 ServerLimit 128 256 512 MaxRequestWorkers 150 250 500 MaxConnectionsPerChild 1000 2500 5000 Keep-Alive On On On Keep-Alive Timeout 1 1 1 Max Keep-Alive Requests 30 30 30 Timeout 60 60 60
Now go to WHM » Service Configuration » Apache Configuration » Include Editor » “Pre VirtualHost Include” and allow users minimal cache and data compression to allow the server to work less for the same things by pasting the code below into the text field.
# Cache Control Settings for one hour cache <FilesMatch ".(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$"> Header set Cache-Control "max-age=3600, public" </FilesMatch> <FilesMatch ".(xml|txt)$"> Header set Cache-Control "max-age=3600, public, must-revalidate" </FilesMatch> <FilesMatch ".(html|htm)$"> Header set Cache-Control "max-age=3600, must-revalidate" </FilesMatch> # Mod Deflate performs data compression <IfModule mod_deflate.c> <FilesMatch ".(js|css|html|php|xml|jpg|png|gif)$"> SetOutputFilter DEFLATE BrowserMatch ^Mozilla/4 gzip-only-text/html BrowserMatch ^Mozilla/4.0[678] no-gzip BrowserMatch bMSIE no-gzip </FilesMatch> </IfModule>
Go to WHM » Service Configuration » “PHP Configuration Editor” and set the parameters according to your needs:
– memory_limit
– max_execution_time
– max_input_time
MySQL
For MySQL you need to update the configuration file that usually in /etc/my.cnf
