nginx upstream负载均衡模块

前言

• upstream 与 proxy 搭配使用

配置upstream

upstream server_www.xxx.com_backend {
    server 192.168.1.128:8081 weight=1;
    server 192.168.1.128:8082 weight=2;
}

配置 server

server {
    listen       80;
    server_name www.xxx.com;
    ...
    location / {
        proxy_pass http://server_www.xxx.com_backend;
        ...
    }
    ...
}
