In the PHP-FPM configuration file, you can adjust the process pool size to control the number of PHP-FPM processes. This can be done by editing the php-fpm.conf file or the pool configuration file. Here are some common settings options:

  1. pm = dynamic: setting the process management mode to dynamic, allowing PHP-FPM to automatically determine the number of processes.
  2. pm.max_children = 50: This sets the maximum number of child processes to 50. This number should be adjusted based on the server’s performance and load.
  3. pm.start_servers = 5: Sets the initial number of child processes started to 5.
  4. pm.min_spare_servers = 2: Configure the minimum number of idle child processes to be 2.
  5. Set the maximum number of spare child processes to 8 by configuring pm.max_spare_servers.

By adjusting these parameters, you can set the number of PHP-FPM processes according to the server’s requirements to achieve better performance and stability. After making changes to the configuration file, you will need to restart the PHP-FPM service for the changes to take effect.
