主机要求：Centos系统，内存64MB及以上、80端口没有被占用

1、升级系统、卸载Apache释放80端口

Yum update -y

Yum remove httpd -y

2、安装EPEL repo

rpm -Uvh http://mirror.ancl.hawaii.edu/linux/epel/6/i386/epel-release-6-8.noarch.rpm

EPEL repo下载地址：https://fedoraproject.org/wiki/EPEL

3、安装Nginx，并设置

安装Nginx

yum install nginx -y

调整Nginx配置

cd /etc/nginx/conf.d mv default.conf default.conf.disabled

4、创建Nginx反代配置文件

cd /etc/nginx/conf.d

vi 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 ACCEPT

service iptables save

service iptables restart

6、启动Nginx

service nginx start
