FastCGI Process Manager (FPM)
&fpm.intro;
These features include:
advanced process management with graceful stop/start;
pools that give ability to start workers with different
uid/gid/chroot/environment, listening on different ports and using
different php.ini (replaces safe_mode);
configurable stdout and stderr logging;
emergency restart in case of accidental opcode cache destruction;
accelerated upload support;
"slowlog" - logging scripts (not just their names, but their PHP
backtraces too, using ptrace and similar things to read remote
process' execute_data) that are executed unusually slow;
fastcgi_finish_request - special function to finish
request and flush all data while continuing to do something
time-consuming (video converting, stats processing etc.);
dynamic/ondemand/static child spawning;
basic and extended status info (similar to Apache mod_status) with
various formats like json, xml and openmetrics supported;
php.ini-based config file.
