corosync起搏器节点显示为在线

Question

我使用corosync，pacemaker和crmsh为HA设置了两个集群节点。现在所有服务都已启动，我发现两台计算机无法正常同步的问题，因为应用程序和VIP都是并行运行的。我该如何同步这些应用程序？

Answer 1

您的配置看起来是错误的

corosync.conf（5） - Linux手册页

bindnetaddr这指定corosync执行程序应绑定到的网络地址。例如，如果本地接口为192.168.5.92，网络掩码为255.255.255.0，则将bindnetaddr设置为192.168.5.0。如果本地接口是192.168.5.92，网络掩码为255.255.255.192，则将bindnetaddr设置为192.168.5.64，依此类推。

所以在你的情况下可能是bindnetaddr：10.193.30.0

Answer 2

1. 运行corosync-cfgtool -s命令检查标准输出。 corosync不应绑定到127.0.0.1环回地址。如果绑定到环回地址检查/ etc / hosts。节点的主机名不应映射到127.0.0.1
2. 要知道如果有裂脑运行pcs cluster status它应该始终是partition with quorum [root @ dmrfv1-mrfc-1~] #pcs cluster status群集状态：堆栈：corosync当前DC：DMRFV1-MRFC-2（版本1.1.16- 12.el7_4.8-94ff4df） - 具有法定人数的分区最后更新时间：Wed Apr 3 06:47:35 2019最后更改：Wed Apr 3 06:41:57 2019 by root via cibadmin on DMRFV1-MRFC-1 2个节点配置11资源配置
