PHP-FPM(8)

💅 php-fpm — the PHP-FPM manual, but make it make sense

okay so bestie, this is the page for php-fpm, aka the PHP FastCGI Process Manager (they literally call it 'PHP-FPM', quotes and all, iconic). come sit, we're learning this together 🫶

---

✨ SYNOPSIS ✨

php-fpm [options]

that's it. that's the whole summoning ritual 💅

---

🌸 DESCRIPTION 🌸

so. PHP is a widely-used general-purpose scripting language that's especially suited for Web development and can be embedded into HTML. you knew that. we all knew that. but this variant — this one right here — runs in the background as a daemon, just sitting there listening for CGI requests like a loyal little guard dog 🐕. its output gets logged to /var/log/php-fpm.log.

most options? not set here, babes. they live in the configuration file, and that file is /etc/php85/php-fpm.conf. by default, php-fpm responds to CGI requests listening on localhost http port 9000. so basically it expects your webserver to forward all requests for .php files to port 9000, and you should edit your webserver configuration file appropriately. no cap, that part's on you 🙈

🎀 OPTIONS 🎀

one bullet per flag, let's go, no skipping, we're eating this whole menu 🍓

• -C — do not chdir to the script's directory. just don't. stay put.
• --php-ini path|file, -c path|file — look for the php.ini file in the directory path, or just use the specified file. your call, main character 💅
• --no-php-ini, -n — no php.ini file will be used. none. zero. empty. the void. 💀
• --define foo[=bar], -d foo[=bar] — define INI entry foo with value bar.
• -e — generate extended information for debugger/profiler. detective mode 🔍
• --help, -h — this help. hi, this is the help. you're looking at it.
• --info, -i — PHP information and configuration.
• --modules, -m — show compiled in modules. show me what you're made of ✨
• --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 the FastCGI process manager configuration file (the default is /etc/php85/php-fpm.conf).
• --test, -t — test the FPM configuration file and exit. and if you call it twice (-tt), the configuration is dumped before exiting. double-tap for the tea ☕
• --daemonize, -D — force it to run in the background and ignore the daemonize option from the configuration file.
• --nodaemonize, -F — force it to stay in the 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). scary. powerful. use responsibly 👑

🦋 FILES 🦋

• php-fpm.conf — the configuration file for the php-fpm daemon.
• php.ini — the standard php configuration file.

🌈 EXAMPLES 🌈

okay so if you're on a unix system that uses init.d as its main process manager, you should use the init script provided to start and stop the php-fpm daemon. like this:

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

and if your unix system uses systemd as its main process manager, you should use the unit file provided to start and stop the php-fpm daemon. like this:

sudo systemctl start php-fpm.service

now. if your installation has no appropriate init script (it happens, don't panic), just launch php-fpm with no arguments. it'll launch as a daemon (background process) by default, because it's an independent queen 💅 the file /var/run/php-fpm.pid determines whether php-fpm is already up and running. and once it's started, php-fpm 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

heads up bestie: SIGINT/SIGTERM is the immediate termination vibe — no soft launch, no goodbye. SIGQUIT is the graceful stop if you're feeling polite. choose accordingly 💀

💖 TIPS 💖

the PHP-FPM CGI daemon will work well with most popular webservers, including Apache2, lighttpd and nginx. it's giving "gets along with everyone" energy, we love a social butterfly 🦋
