cpanel中的php运行方式使用fast-cgi模式的配置方法

# 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
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php5
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php4
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php3
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php2
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .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 $2}’ | 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!)

ThreadStackSize 4000000
ServerLimit 2
