配置Nginx运行CGI(Perl-cgi)

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 http://www.cpan.org/modules/by-module/FCGI/FCGI-0.67.tar.gz    

tar -zxvf FCGI-0.67.tar.gz     
cd FCGI-0.67     
perl Makefile.PL    
make && make install

安装FCGI-ProcManager:
wget http://search.cpan.org/CPAN/authors/id/G/GB/GBJK/FCGI-ProcManager-0.18.tar.gz    
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

#!/usr/bin/perl -w
