心脏起搏器节点在线显示

Question

我已经为HA设置了两个集群节点，它们分别使用corosync、定搏器和crmsh。现在所有的服务都结束了，我发现了一个问题，那就是两台机器不能正确同步，因为应用程序和VIP都是并行运行的。如何同步这些应用程序？

Answer 1

你的配置看起来不对

corosync.conf(5) - Linux手册页

bindnetaddr --这指定了corosync执行人员应该绑定到的网络地址。例如，如果本地接口为192.168.5.92和net掩码255.255.0，则将bindnetaddr设置为192.168.5.0。如果本地接口为192.168.5.92，则将bindnetaddr设置为192.168.5.64，以此类推。

所以在您的例子中，可能是bindnetaddr: 10.193.30.0。

1. 运行corosync-cfgtool -s命令检查标准输出。Cor产c不应绑定到127.0.0.1回送地址。如果它绑定回回地址，检查/etc/主机。节点的主机名不应映射到127.0.0.1
2. 要知道，如果存在拆分大脑运行的pcs cluster status，则始终应该是partition with quorum root@dmrfv1-mrfc-1 ~# DC集群状态群集状态:堆栈:COMRFFV1-MRFC-2(版本1.1.16-12.el7_4.8-94ff4df) -分区与法定人数:W得4月3日06:47:35 2019最后更改: on 04月3日06:on 04月3日06:41:57 2019
