Compared with Spawn-FCGI, PHP-FPM has better control over CPU and memory, and the former is easy to crash and must be monitored with crontab, while PHP-FPM has no such troubles. PHP5.3.3 has already integrated php-fpm and is no longer a third-party package. PHP-FPM provides a better way of PHP process management, can effectively control the memory and process,

process is about 3 m memory, but some memory cannot be released after they have processed some requests, the occupied memory can reach 20 M-30M. For applications with a tight memory and a low concurrency, you can use static mode to control the total memory consumption of php-fpm, make the system run more smoothly. In addition, because the concurrency is small, you can set pm. max_requests to a smaller value, so that the php-fpm process can be restarted and the occupied memory can be released. U

It provides a better PHP process management method, which can effectively control the memory and processes, and can smoothly reload PHP configurations. it has more advantages than spawn-fcgi, so it is officially recorded by PHP. You can enable PHP-fpm with the enable-FPM parameter in./configure. Use PHP-FPM to c
