12.24 PHP-FPM Process Management

PM = dynamic/Active process management, also can be static
Pm.max_children = 50//maximum number of sub-processes, PS aux can be viewed
Pm.start_servers = 20//Number of processes that will start when the service is started
Pm.min_spare_servers = 5//Defines the minimum number of child processes in the idle period, and if this value is reached, the PHP-FPM service automatically derives the new child process.
Pm.max_spare_servers = 35//Defines the maximum number of child processes in the idle period, or, if higher than this value, to start cleaning up idle child processes.
Pm.max_requests = 500//defines the maximum number of requests processed by a child process, that is, a PHP-FPM child process can handle so many requests, and when this value is reached, it exits automatically.
