defaults
    mode   http   ###默认的模式mode { tcp|http|health },tcp是4层,http是7层,health只会返回OK
    log    global     ###采用全局定义的日志
    option  dontlognull   ###不记录健康检查的日志信息
    option  httpclose    ###每次请求完毕后主动关闭http通道 
    option  httplog     ###日志类别http日志格式 
    option  forwardfor   ###如果后端服务器需要获得客户端真实ip需要配置的参数,可以从Http Header中获得客户端ip  
    option  redispatch   ###serverId对应的服务器挂掉后,强制定向到其他健康的服务器
    timeout connect 10000  #default 10 second timeout if a backend is not found
    timeout client 300000  ###客户端连接超时
    timeout server 300000  ###服务器连接超时
    maxconn     60000  ###最大连接数
    retries     3    ###3次连接失败就认为服务不可用,也可以通过后面设置
