centos环境下搭建LNMP

本文描述了如何在centos5.9环境下搭建LNMP环境

吐槽: 之前在ubuntu下面搭过一次，这次因为某种需要再来一次，无语。。。

使用网页的软件源

1
2

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget http://mirrors.163.com/.help/CentOS5-Base-163.repo -O /etc/yum.repos.d/CentOS-Base-163.repo

安装php

卸载系统默认php

1

yum remove php php-common

安装php5.3

1

yum install php53 php53-devel php53-cli

安装spawn-fcgi, php-fastcgi

1
2

wget http://centos.alt.ru/repository/centos/5/i386/centalt-release-5-3.noarch.rpm
yum install spawn-fcgi

php-fastcgi脚本

/usr/bin/php-fastcgi

#!/bin/sh
/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 6 -u nginx -g nginx -f /usr/bin/php-cgi

tips

  • 由于centos默认的iptables是开着的，所以上述装好之后，需要关闭iptables或者配置规则才能使用。
