负载均衡

http {
    upstream upstream_name{
        server 192.168.0.28:8001 weight=2;  # 50%的访问机会
        server 192.168.0.28:8002;
        server 192.168.0.28:8002;
    }

    server {
        listen       8080;
        server_name  localhost;

        location / {
            proxy_pass http://upstream_name;
        }
