<spanmicrosoft yahei'; font-size:20px; color:rgb(255,0,0)">3）、如果master服务器上的nginx服务挂了，则vip资源转移到backup服务器上

<spanmicrosoft yahei'; font-size:20px; color:rgb(255,0,0)">4）、检测后端服务器的健康状态

<spanmicrosoft yahei'; font-size:20px">Master和Backup两边都开启nginx服务，无论Master还是Backup，当其中的一个keepalived服务停止后，vip都会漂移到keepalived服务还在的节点上，

<spanmicrosoft yahei'; font-size:20px">如果要想使nginx服务挂了，vip也漂移到另一个节点，则必须用脚本或者在配置文件里面用shell命令来控制。

<spanmicrosoft yahei'; font-size:20px">首先必须明确后端服务器的健康状态检测keepalived在这种架构上是无法检测的，后端服务器的健康状态检测是有nginx来判断的，但是nginx的检测机制有一定的缺陷，后端服务器某一个宕机之后，nginx还是会分发请求给它，在一定的时间内后端服务响应不了，nginx则会发给另外一个服务器，然后当客户的请求来了，nginx会一段时间内不会把请求分发给已经宕机的服务器，但是过一段时间后，nginx还是会把分发请求发给宕机的服务器上。
