1、升级系统、卸载Apache释放80端口
Yum update -yYum remove httpd -y
2、安装EPEL repo
rpm -Uvh http://mirror.ancl.hawaii.edu/linux/epel/6/i386/epel-release-6-8.noarch.rpmEPEL
3、安装Nginx，并设置
安装Nginx
yum install nginx -y调整Nginx配置
cd /etc/nginx/conf.dmv default.conf default.conf.disabled
4、创建Nginx反代配置文件
cd /etc/nginx/conf.dvi yourdomain.com
粘贴以下内容：
server {listen 80;server_name yourdomain.com;access_log off;error_log off;location / {proxy_pass http://需要反代的服务器IP/;proxy_redirect off;proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_max_temp_file_size 0;client_max_body_size 10m;client_body_buffer_size 128k;proxy_connect_timeout 90;proxy_send_timeout 90;proxy_read_timeout 90;proxy_buffer_size 4k;proxy_buffers 4 32k;proxy_busy_buffers_size 64k;proxy_temp_file_write_size 64k;}}
然后保存。
5、设置防火墙，允许80端口访问
iptables -I INPUT 5 -m state --state NEW -p tcp --dport 80 -j ACCEPTservice iptables saveservice iptables restart
6、启动Nginx
service nginx start
