nginx代理

vim /usr/local/nginx/conf/vhosts/proxy.conf

server {

listen 80;

server_name www.baidu.com;

localtion / {

proxy_pass http://ip/;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

}

}

dig www.baidu.com

查看百度有多少ip

如果后端的机器有多台，还可以用upstream来实现负载均衡

upstream 自定义名字

service ip:端口

service ip

server {

listen 80;

server_name www.baidu.com;

localtion / {

proxy_pass http://自定义的名字/;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

}

}
