原因：由于centos没有默认的nginx软件包，需要启用REHL的附件包

rpm -Uvh http://download.Fedora.RedHat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm
yum -y install nginx

设置开机启动

chkconfig nginx on

安装spawn-fcgi来运行php-cgi

yum install spawn-fcgi

下载spawn-fcgi 的启动脚本

wget http://bash.cyberciti.biz/dl/419.sh.zip
unzip 419.sh.zip
mv 419.sh /etc/init.d/php_cgi
chmod +x /etc/init.d/php_cgi

启动php_cgi

/etc/init.d/php_cgi start

查看进程

netstat -tulpn | grep :9000

若出现如下代表一切正常

tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 4352/php-cgi

配置nginx(详细配置见nginx.conf详细说明)

location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
include fastcgi_params;
}

查看phpinfo
phpinfo();

安装phpmyadmin
修改/var/lib/php/session的权限和nginx和php_cgi一致

chown -R www.www /var/lib/php/session

vi /etc/yum.repos.d/CentOS-Base.repo
更改内容如下

# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

二、update yum

yum -y update
