2 weight

 upstream myserver {
        server 39.102.128.122:8081 weight=10;   #  這裏配置
        server 39.102.128.122:8082 weight=10;
    }
    server {
        listen       80;
        server_name  39.102.128.122;
        location / {
            root   html;
            proxy_pass   http://myserver;
            index  index.html index.htm;
    }

3 ip_hash

每個請求按訪問 ip 的 hash 結果分配，這樣每個訪客固定訪問一個後端服務器 

 

    upstream myserver {
    	ip_hash;							//  這裏配置
        server 39.102.128.122:8081 ;   
        server 39.102.128.122:8082 ;
    }
    server {
        listen       80;
        server_name  39.208.128.122;
        location / {
            root   html;
            proxy_pass   http://myserver;
            index  index.html index.htm;
    }
