.TH PHP-FPM 8 "2018" "The PHP Group" "Scripting Language"
.SH NAME
.TP 15
php-fpm \- PHP FastCGI Process Manager 'PHP-FPM'
.SH SYNOPSIS
.B php-fpm
[options]
.LP
.SH DESCRIPTION
\fBPHP\fP 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.
.LP
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.

.SH 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.
.P
.PD 1
.RS
sudo /etc/init.d/php-fpm start
.RE
.TP
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.
.P
.PD 1
.RS
sudo systemctl start php-fpm.service
.RE
.TP
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:
.P

.TP
.B SIGUSR1 			\fPre-open log file
