12 PHP is a widely-used general-purpose scripting language that is espe‐
13 cially suited for Web development and can be embedded into HTML. This
14 is a variant of PHP that will run in the background as a daemon, lis‐
15 tening for CGI requests. Output is logged to /var/log/php-fpm.log.
16
17 Most options are set in the configuration file. The configuration file
18 is /etc/php-fpm.conf. By default, php-fpm will respond to CGI requests
19 listening on localhost http port 9000. Therefore php-fpm expects your
20 webserver to forward all requests for '.php' files to port 9000 and you
21 should edit your webserver configuration file appropriately.

80 php-fpm.conf The configuration file for the php-fpm daemon.
81
82 php.ini The standard php configuration file.
83
85 For any unix systems which use init.d for their main process manager,
86 you should use the init script provided to start and stop the php-fpm
87 daemon.
88
89 sudo /etc/init.d/php-fpm start
90
91 For any unix systems which use systemd for their main process manager,
92 you should use the unit file provided to start and stop the php-fpm
93 daemon.
94
95 sudo systemctl start php-fpm.service
96
97 If your installation has no appropriate init script, launch php-fpm
98 with no arguments. It will launch as a daemon (background process) by
99 default. The file /var/run/php-fpm.pid determines whether php-fpm is
100 already up and running. Once started, php-fpm then responds to several
101 POSIX signals:
102
103 SIGINT,SIGTERM immediate termination
104 SIGQUIT graceful stop
105 SIGUSR1 re-open log file
106 SIGUSR2 graceful reload of all workers + reload of
107 fpm conf/binary
108
110 The PHP-FPM CGI daemon will work well with most popular webservers, in‐
111 cluding Apache2, lighttpd and nginx.
