nginx开启负载均衡

nginx.conf 配置文件如下：

upstream myServerSetting {
    server 127.0.0.1:8081 weight=5;
    server 127.0.0.1:8082 weight=2;
    server 127.0.0.1:8082 weight=2;
    ip_hash; #每个ip只对应一个server，避免session问题
    fair; #性能时间响应优先
}

location / {
    proxy_pass http://myServerSetting;
    root   html;
    index  index.html index.htm;
}
