PHP-FPM(8)

NAME

php-fpm - PHP FastCGI Process Manager 'PHP-FPM'

SYNOPSIS
php-fpm [options]

DESCRIPTION
PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. This is a variant of PHP that will run in the background as a daemon, listening for CGI requests. Output is logged to @php_fpm_localstatedir@/log/php-fpm.log.

Most options are set in the configuration file. The configuration file is @php_fpm_sysconfdir@/php-fpm.conf. By default, php-fpm will respond to CGI requests listening on localhost http port 9000. Therefore php-fpm expects your webserver to forward all requests for '.php' files to port 9000 and you should edit your webserver configuration file appropriately.

FILES

php-fpm.conf
    The configuration file for the php-fpm daemon.

php.ini
    The standard php configuration file.

EXAMPLES
For any unix systems which use init.d for their main process manager, you should use the init script provided to start and stop the php-fpm daemon.

    sudo /etc/init.d/php-fpm start

For any unix systems which use systemd for their main process manager, you should use the unit file provided to start and stop the php-fpm daemon.

    sudo systemctl start php-fpm.service

If your installation has no appropriate init script, launch php-fpm with no arguments. It will launch as a daemon (background process) by default. The file @php_fpm_localstatedir@/run/php-fpm.pid determines whether php-fpm is already up and running. Once started, php-fpm then responds to several POSIX signals:

    SIGINT,SIGTERM immediate termination
    SIGQUIT graceful stop
    SIGUSR1 re-open log file
    SIGUSR2 graceful reload of all workers + reload of fpm conf/binary

TIPS
The PHP-FPM CGI daemon will work well with most popular webservers, including Apache2, lighttpd and nginx.
