cpanel의 PHP 실행 모드는 fast-cgi 모드의 구성 방법을 사용합니다.

# Fastcgi configuration for PHP5
LoadModule fcgid_module modules/mod_fcgid.so
MaxRequestsPerProcess 15
MaxRequestLen 15728640
ProcessLifeTime 120
IdleTimeout 30
DefaultMinClassProcessCount 0
DefaultMaxClassProcessCount 3
IPCConnectTimeout 60
IPCCommTimeout 30
AddHandler fcgid-script .php5 .php4 .php .php3 .php2 .phtml

# End of autogenerated PHP configuration.

保存好之后，重启apache。

4.由于大量php进程长期占用内存，可以每小时执行一次清空php进程。 crontab -e 把光标弄到最下 0 * * * * ps aux | grep php | egrep -v grep | awk ‘{print }’ | xargs kill -9 Ctrl O保存，Enter，Ctrl X退出

对于第3步，也另有老外总结出其它方法： 登录 WHM->Apache Configuration->Include Editor->Pre Virtual host Include

特别关注地是: - DefaultMinClassProcessCount 0 (necessary to make Idle timeout work) - ThreadStackSize (default is too high, wastes memory, the setting below is good for most and will save enough memory to allow another php thread!)
