6.1.1安装问题

[huiliaoning]

使用6.1.1 添加集群-从主机开始安装，在高级配置里面配置了外部数据库mysql。但是在下一步初始化平台过程中，集群组件(9/10)，9个状态全部为running了。除了rbd-db之外，且rbd-db一直没有安装成功，且无法点击下一步。

按理说在配置了外部数据库mysql情况下， 在在下一步初始化平台过程不应该再安装rbd-db了，麻烦看一下是不是安装脚本逻辑问题，还是我操作有问题

Title: 6.1.1 Installation issues

Use 6.1.1 to add a cluster - start the installation from the host, and configure the external database mysql in the advanced configuration. However, in the next step of initializing the platform, all nine statuses of the cluster component (9/10) are running. Except for rbd-db, rbd-db has not been successfully installed and cannot click Next.

It stands to reason that when the external database mysql is configured, rbd-db should not be installed in the next step of initializing the platform. Please check if there is a problem with the installation script logic or if there is something wrong with my operation
