准备工作：三台配置好的服务器(centos7.0 + mysql5.7 + php7.0 + nginx/1.10.3)

配置nginx.cong文件

[root@localhost conf]# vim /usr/local/nginx/conf/nginx.conf

在http段配置(采用hash策略):
upstream cluster{
server 192.168.2.8:80;
server 192.168.2.23:80;
ip_hash;
}

在server端配置:

server {
listen 80;
server_name cluster;
location / {
proxy_pass http://cluster/; proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

重启nginx服务,访问http://localhost/index.php
