How to restart PHP-FPM

Here’s how to restart PHP-FPM on various operating systems:

Debian/Ubuntu:

1. Use the following command:
   • sudo systemctl restart php8.0-fpm (Replace “php8.0” with your specific PHP version if different)

CentOS/RHEL:

1. Use this command:
   • sudo systemctl restart php-fpm  

Fedora:

1. Use this command:
   • sudo systemctl restart php-fpm.service

Alternative Methods (if the above commands don’t work):

• Check for specific service name:
  • sudo systemctl list-units | grep php-fpm  Use the exact service name from the output in the restart command.
• Directly restart the process:
  • sudo killall -HUP php-fpm

Troubleshooting:

• Check status: Verify if PHP-FPM is running with:
  • sudo systemctl status php-fpm  
• View logs: Look for errors in the PHP-FPM logs (usually in /var/log/php-fpm) for more clues.

Important Notes:

• Root privileges: You’ll need root privileges (using sudo) to restart PHP-FPM.
• Service names: Service names might vary slightly depending on your system and configuration.
• Multiple PHP versions: If you have multiple PHP versions, specify the correct one in the restart command.
• Web server integration: Ensure your web server is configured to use the correct PHP-FPM socket or port after restarting.
