Question

我在Ubuntu 14 LTS上安装了一个MemSQL服务器集群。我无法连接到端口3306上的memsql，但群集正在端口9000上运行。看起来像一片叶子了。当我尝试将memsql升级到版本4.0.1时，我收到此错误： -

Starting MemSQL Upgrade
Currently on state OfflineClusterUpgrade.Init
Currently on state OfflineClusterUpgrade.SnapshottingDatabases
Currently on state OfflineClusterUpgrade.OfflineClusterUpgradeFail
MemSQL node 8D84F89D6716F03A44EACB9E3AF6565FA76B9DE9 failed to upgrade: Could not connect to MemSQL node 8D84F89D6716F03A44EACB9E3AF6565FA76B9DE9. Is the MemSQL node online?

如何重新启动MemSql？

Answer 1

集群管理器在端口9000上提供了帮助。首先，它清楚地显示了所有节点的状态。

点击警告图标显示解决方案。

我运行了命令

memsql-ops cluster-start

它导致节点恢复并重新启动。这真的很好。

MemSql在单服务器群集上向下移动
