一直没有看到详细关于IP切换的配置方法,终于在一份文档里找到了几句话,感觉过于简单了
自动IP切换(不推荐)
There are two ways to associate the application takeover IP address with an application cluster resource group (CRG) managed. The easiest way, which is the default, is for Cluster Resource Services to manage the IP address. This method directs Cluster Resource Services to create the IP address on all nodes in the recovery domain, including nodes that were subsequently added to the recovery domain. When this method is selected, the IP address cannot currently be defined on any node in the recovery domain.
手动IP切换(推荐)
The alternative way is to manage the IP addresses yourself. This method directs Cluster Resource Services not to take any steps to configure the IP address. The user is responsible for the configuration. You must add the takeover IP address on all nodes in the recovery domain (except on replicate nodes) before you start the CRG. |
