反向代理

在 nginx.conf 中添加参数

server {
        listen       80;
        server_name  localhost;
    // 将 / 路由的消息转发到 http://127.0.0.1:8080
    location / {
            root   http://127.0.0.1:8080;
    }
}

负载均衡

在 http 配置中增加 upstream 配置

http {
        include       mime.types;
    default_type  application/octet-stream;
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';
    #access_log  logs/access.log  main;
    sendfile        on;
    #tcp_nopush     on;
    #keepalive_timeout  0;
    keepalive_timeout  65;
    #gzip  on;
      # server_name 表示服务器的名字
        upstream server_name {
                server 192.168.1.116 8080  weight=2; # weight 表示权重， 权重最高的服务器最常选择
        server 192.168.1.116 8181  weight=1; #
        }    
    location / {
            root   http://server_name; # 从 server_name 中获取1个 服务器地址
    }
}
