PHP-FPM(8)

📦 version 8.4.27, in alpine 3.24

💅 PHP-FPM(8) — the php-fpm girlies' manual

okay so bestie, you're reading the php-fpm manpage, from the PHP-FPM(8) manual set, in the Scripting Language section — and honestly? you came to the right place. let's get into it 🫶

✨ NAME ✨

php-fpm — the PHP FastCGI Process Manager, aka 'PHP-FPM'. that's her full government name 💅

🌸 SYNOPSIS 🌸

php-fpm [options]

like, that's it. options only. she's low maintenance like that.

🦋 DESCRIPTION 🦋

so PHP is this widely-used general-purpose scripting language, right? and it's especially suited for Web development and can be embedded into HTML. that's the whole vibe.

this version of PHP is the one that runs in the background as a daemon, listening for CGI requests. and where does her output go? /var/log/php-fpm.log. periodt, that's the log file.

most options are set in the configuration file — which lives at /etc/php84/php-fpm.conf. by default, php-fpm responds to CGI requests listening on localhost http port 9000. so she's literally expecting your webserver to forward all requests for '.php' files to port 9000, and you should go edit your webserver configuration file appropriately. no cap, that part matters. 🔥

💅 OPTIONS 💅

  • -C — do not chdir to the script's directory
  • --php-ini path|file, -c path|file — look for the php.ini file in the directory path, or use the specified file
  • --no-php-ini, -n — no php.ini file will be used, none, zero, nada 🙈
  • --define foo[=bar], -d foo[=bar] — define INI entry foo with value bar
  • -e — generate extended information for debugger/profiler
  • --help, -h — this help
  • --info, -i — PHP information and configuration
  • --modules, -m — show compiled in modules
  • --version, -v — version number
  • --prefix path, -p — specify alternative prefix path (the default is /usr)
  • --pid file, -g — specify the PID file location
  • --fpm-config file, -y — specify alternative path to FastCGI process manager configuration file (the default is /etc/php84/php-fpm.conf)
  • --test, -t — test FPM configuration file and exit. and ooh, if called twice (-tt), the configuration is dumped before exiting 👀
  • --daemonize, -D — force to run in background and ignore the daemonize option from the configuration file
  • --nodaemonize, -F — force to stay in foreground and ignore the daemonize option from the configuration file
  • --force-stderr, -O — force output to stderr in nodaemonize even if stderr is not a TTY
  • --allow-to-run-as-root, -R — allow pool to run as root (disabled by default — and honestly bestie, keep it that way 💀)

🎀 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

and if your installation has no appropriate init script? just launch php-fpm with no arguments. she'll launch as a daemon (background process) by default, main character energy fr fr. the file /var/run/php-fpm.pid determines whether php-fpm is already up and running.

once started, php-fpm then responds to several POSIX signals — like, this is the whole signals moment, pay attention:

SIGINT,SIGTERM      immediate termination
SIGQUIT             graceful stop
SIGUSR1             re-open log file
SIGUSR2             graceful reload of all workers + reload of
fpm conf/binary
the SIGINT,SIGTERM one is immediate termination — no gentle goodbyes, she's just gone. SIGQUIT is your graceful stop bestie. 💀

🌈 TIPS 🌈

the PHP-FPM CGI daemon will work well with most popular webservers, including Apache2, lighttpd and nginx. she's versatile, she's friendly, she gets along with everyone 🧚
