lb_algo 实现keepalive，
这块的参数在如果进行多个memcache进行连接时很重要：
LVS的10个调度算法 :
keepalived 配置有个 lb_algo的参数，参照下面的文章设置 http://chqz1987.blog.163.com/blog/static/51438311201272804410941/

virtual_server 61.164.122.8 80 {  
    delay_loop 6                  #(每隔10秒查询realserver状态)  
    lb_algo wrr                  #(lvs 算法)  
    lb_kind DR                  #(Direct Route)  
    persistence_timeout 60        #(同一IP的连接60秒内被分配到同一台realserver)  
    protocol TCP                #(用TCP协议检查realserver状态)  
  
    real_server 61.164.122.9 80 {  
        weight 3               #(权重)  
        TCP_CHECK {  
        connect_timeout 10       #(10秒无响应超时)  
        nb_get_retry 3  
        delay_before_retry 3  
        connect_port 80  
        }  
    }  
    real_server 61.164.122.10 80 {  
        weight 3  
        TCP_CHECK {  
        connect_timeout 10  
        nb_get_retry 3  
        delay_before_retry 3  
        connect_port 80  
        }
