How to install php fpm

PHP FPM is a FastCGI process manager for PHP that can handle high-traffic websites and improve performance. In this article, we will show you how to install PHP FPM.

Installing PHP FPM

PHP FPM is shipped with PHP, so by default, no separate installation is required. However, if you are using Linux, you need to install the FPM package. To install run the following commands:

Debian/Ubuntu:

sudo apt-get install php-fpm

CentOS/RHEL:

sudo yum install php-fpm

Start PHP FPM

Once you have installed PHP FPM, you can start it using the following command:

sudo systemctl start php-fpm

You can check the status of FPM using the following command:

sudo systemctl status php-fpm

If FPM is running, you should see the message "active (running)".

Configuration PHP FPM

By default, PHP FPM uses the configuration file "/etc/php/fpm/php-fpm.conf". You can open the file with a text editor to make changes.

For example, you can change the following setting:

listen = /run/php/php7.4-fpm.sock
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35

This configuration file configures PHP FPM to use Unix sockets for communication and sets max_children to 50 in order to handle more ask.
