yum –y install zlib zlib-devel openssl openssl--devel pcre pcre-devel
检查现有系统是否安装Nginx：
Find –name ngxin
如果有nginx信息输出，则卸载原有的nginx。

将安装包上传到/usr/local中之后执行之下操作：
cd /usr/local
tar –zxvf nginx-1.4.7.tar.gz
rm –rf nginx-1.4.7.tar.gz
mv nginx-1.4.7 nginx
cd /usr/local/nginx
./configure –prefix = /usr/local/nginx
Make
Make install
修改防火墙配置：
Vi +/etc/sysconfig/iptables
添加配置项目：
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT（80端口加入安装端口，防火墙不拦截）
重启防火墙
Service iptables restart
启动nginx
Cd /usr/local/nginx/sbin
./nginx
停止Nginx
查询nginx住进程号
Ps –ef |grep nginx
停止进程
Kill -9 住进程号
重启Nginx
/usr/local/nginx/sbin/nginx –s reload
测试Nginx是否启动成功
Netstat –na | grep 80
浏览器中测试：直接访问服务器IP地址，出来Nginx欢迎界面即表示成功。
