假设需求访问谷歌

[root@LNMP vhosts]#vim  /usr/local/nginx/conf/vhosts/proxy.conf

server {

     listen 80;

     server_name www.baidu.com;

     location / {

           proxy_pass http://180.97.33.107/; #百度的IP

           #proxy_set_header Host $host;

     }

}

--------------------------

访问测试

-----------------------------------------------------------------

nginx 实验负载均衡：用dig 命令查出百度的另一个IP

[root@LNMP vhosts]#vim  /usr/local/nginx/conf/vhosts/proxy.conf

upstream baidu{

      server 180.97.33.108:80;

      server 180.97.33.107;

}

server {

     listen 80;

     server_name www.baidu.com;

     location / {

           proxy_pass http://baidu/;

           proxy_set_header Host $host;  # 这行要打不开，不然访问的时候会报 502

           #proxy_set_header X-Real-IP $remote_addr;

     }

}
