Configure PHP-FPM processes

NOTE: The Approach A sections referred to below do not apply to Bitnami native installers. Users of Bitnami native installers should refer only to the Approach B sections.

It is possible to configure PHP-FPM processes per application. If you have a lot of applications, this may result in excessive CPU usage.

• You can configure your application’s PHP-FPM processes to start automatically when needed. Add this option to the PHP-FPM pool configuration file:

  NOTE: Depending on your installation type, you can find the PHP-FPM pool configuration file for your application in the following locations:

  • Approach A (Bitnami installations using system packages): installdir/php/etc/php-fpm.d/www.conf
  • Approach B (Self-contained Bitnami installations): installdir/apps/APPNAME/conf/php-fpm/pool.conf

    pm=ondemand
  

• You can also reduce the number of PHP-FPM processes per application by modifying the files below.

  • If you configured the processes to start dynamically, modify the installdir/php/etc/common-dynamic.conf as below:

      pm=dynamic
      pm.max_children=5
      pm.start_servers=2
      pm.min_spare_servers=1
      pm.max_spare_servers=3
    

  • If you configured the processes to start on demand, modify the installdir/php/etc/common-ondemand.conf as below:

      pm=ondemand
      pm.max_children=5
      pm.start_servers=2
      pm.min_spare_servers=1
      pm.max_spare_servers=3
