    #设定负载均衡的服务器列表 支持多组的负载均衡,可以配置多个upstream  来服务于不同的Server.

    #nginx 的 upstream 支持 几 种方式的分配

    #1)、轮询（默认） 每个请求按时间顺序逐一分配到不同的后端服务器，如果后端服务器down掉，能自动剔除。

    #2)、weight 指定轮询几率，weight和访问比率成正比，用于后端服务器性能不均的情况。 跟上面样，指定了权重。

    #3)、ip_hash 每个请求按访问ip的hash结果分配，这样每个访客固定访问一个后端服务器，可以解决session的问题。 

    #4)、fair      

    #5)、url_hash #Urlhash

    upstream mysvr {

      #weigth参数表示权值，权值越高被分配到的几率越大

      #1.down 表示单前的server暂时不参与负载

      #2.weight 默认为1.weight越大，负载的权重就越大。

      #3.backup： 其它所有的非backup机器down或者忙的时候，请求backup机器。所以这台机器压力会最轻。

      #server 192.168.1.116  down;

      #server 192.168.1.116  backup;

      server 192.168.1.121  weight=1;
