笔者的nginx安装目录为/usr/local/nginx
虚拟机配置文件为/usr/local/nginx/conf/vhosts.conf
目前php fast-cgi已支持
以下操作均在su下完成
=====================
安装perl cgi模块
wget
tar -zxvf FCGI-0.67.tar.gz
cd FCGI-0.67
perl Makefile.PL
make && make install
安装FCGI-ProcManager:
wget
tar -xzxf FCGI-ProcManager-0.18.tar.gz
cd FCGI-ProcManager-0.18
perl Makefile.PL
make make install
===================
先在/bin目录下放置一个perl写的分发器，取名叫perl-fcgi
vi /bin/perl-cgi

给这个脚本执行权限
