不同域名实现负载均衡

upstream backend{\tserver 192.168.1.2:80 weight=5;\tserver 192.168.1.3:80 weight=2;\tserver 192.168.1.4:80;  #默认weight=1}

URL重写的负载均衡

upstream searchbox_searchbox-po_server_name {    keepalive 8;    server 10.23.240.136:8210;    server 10.23.240.149:8210;}server {    listen       8080;    server_name  baijiahao.baidu.com;    location / {    \tproxy_pass http://searchbox_searchbox-po_server_name;    \tbreak;    }}
