心跳让我心痛

我有 2 台 Ubuntu 11.04 VM，并在其上安装了 Heartbeat + apache2 以实现“高可用性”设置。Heartbeat 在两台虚拟机上都已启动并运行，但我无法 ping 虚拟 IP（集群 IP）

根据我遵循的指南，Heartbeat 应该自动在活动节点上创建别名。但我在两个虚拟机中都没有看到任何别名

设置如下：

crm_mon -1告诉我配置了 0 个资源。但我已IPaddr在 haresources 中明确添加了资源。我无法 ping 或浏览虚拟 IP。我在设置中做错了什么吗？

答案1

0 Resources configured表示故障转移 IP 是未配置作为 HA 资源。

顺便说一句，如果您只需要 IP 故障转移，那么 CARP（通过 ucarp/ucarpd）就简单得多。
