我试图从完整的 AMI 映像在不同的 EC2 主机（具有不同的 ip 地址）上启动我的 MemSQL、社区版、单主机集群。 我已经尝试了如何更改memsql节点的IP地址中的建议，但我无法使其工作。 我可以通过Web界面连接到MemSQL-ops。 它在具有新 IP 地址的新本地主机上显示主聚合器。 但是，它仍在旧 IP 地址处查找群集。 我试图取消监视/监视主聚合器和叶子。命令和错误的输出如下：
10.0.0.232: ~$ sudo memsql-ops memsql-start --all

Would you additionally like to remove the leaf node from the MemSQL cluster? (You can specify this behavior with --remove-leaf.) [y/n] n

看起来 memsql ops 正在使用 memsql-ops 代理的 IP 地址。要修复它，您需要一个额外的步骤：
- Memsql-ops MemSQL-Unmonitor for each Memsql node
- sudo memsql-ops stop
- sudo memsql-ops start --host 127.0.0.1
- memsql-ops memsql-monitor [-h 127.0.0.1] [-P PORT] for each memsql node
