Install PHP and PHP-FPM

PHP-FPM is used together with a web server like Apache or NGINX, PHP-FPM serves dynamic content, while the web server serve static content and act like a reverse proxy in front of PHP-FPM.

PHP-FPM introduces the concept of pools, each pool can receive connections on a TPC/IP (IP:Port) socket or on a UNIX socket, and can run under a different user and group also each pool has its configuration file, to install PHP and PHP-FPM execute the following command:

# pkgin install php80-fpm

Manage the PHP-FPM service

In this section we learn how to start, restart and stop the php-fpm service, for this task we are going to use the excelent tools: init, rc and service.

Add init script

The php80-fpm package provides us and example script located under /usr/pkg/share/examples/rc.d/php_fpm and we can use it as our init script copying it to /etc/rc.d/php_fpm.

# cp -v /usr/pkg/share/examples/rc.d/php_fpm /etc/rc.d/
/usr/pkg/share/examples/rc.d/php_fpm -> /etc/rc.d/php_fpm

Automatic start

I love how *BSD handle services automatic start, simply add to the /etc/rc.conf file this line:

php_fpm=YES

The above line instructs to the init system that the php_fpm will start automatically after a system reboot.

Check status

# service php_fpm status 
php_fpm is not running.

Start

# service php_fpm start
Starting php_fpm.

Check the status again :

# service php_fpm status
php_fpm is running as pid 1995.

Restart

If you did any modification to the configuration files you need to refresh the changes with:

# service php_fpm restart
Stopping php_fpm.
Starting php_fpm.

In the next post we are going to show how to integrate PHP-FPM with NGINX.
