Dont Leave Web Server Performance on the Table

Written by: Robert R. Russell on Saturday, August 29, 2020.

If you followed the WordPress Install Guide you are leaving performance on the table for your website. The WordPress Install Guide defaults to Apache’s mod_PHP which is definitely leaving performance on the table.

Here is how to fix that in Ubuntu 20.04:

  1. install php-fpm: sudo apt install php-fpm
  2. disable mod_php and mpm_prefork: sudo a2dismod php mpm_prefork
  3. enable mpm_event proxy_fcgi and setenvif: sudo a2enmod mpm_event proxy_fcgi setenvif
  4. enable the php-fpm configuration file: sudo a2enconf php7.4-fpm
  5. mark apache2 as a manually installed package: sudo apt-mark manual apache2
  6. remove mod_php: sudo apt purge libapache2-mod-php*

That takes care of the general Apache configuration. The next configuration adjustments need to be done at the vhost level. Substitute the correct information for YOUREMAIL, YOURDOMAIN, and WPDIR, and you are good to go.

<VirtualHost *:443>
Protocols h2 http/1.1
ServerAdmin [email protected]

DocumentRoot "WPDIR"

<Directory "WPDIR">
    <FilesMatch "\.php$">
 #Proxy php files to php-fpm
        SetHandler  "proxy:unix:/run/php/php-fpm.sock|fcgi://localhost/"
    Options All
    AllowOverride All
    DirectoryIndex index.php
    Require all granted

#Protect the uploads directory.
<Directory "WPDIR/wp-content/uploads/">
    <FilesMatch "\.php$">
        SetHandler  none
        Require all denied

#snip extraneous stuff
