nginx配置http负载均衡转发

在http内新增如下代码

//要被转发到的地址
upstream mqttservice{
        server ip1:18083 weight=1;
        server ip2:18083 weight=1;
        server ip3:18083 weight=1;
    }

    server {
        listen       9816;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_pass http://mqttservice;
        }
    }
