MemSql在单服务器群集上向下移动

Question

我在Ubuntu 14 LTS上安装了一个MemSQL的服务器集群.我无法连接到端口3306上的memsql,但群集正在端口9000上运行.看起来像一片叶子已关闭.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?

我怎样才能再次启动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.

点击它的警报图标显示了解决方案.

我跑了命令

memsql-ops cluster-start

它导致节点恢复并重新启动.这真的很好.
