After migrating the .tiup control center as per the following method, executing the tiup cluster list command keeps hanging without returning. How can I troubleshoot this issue? Passwordless SSH has already been set up, and ssh ip hostname can be executed successfully.

If the tiup cluster list command gets stuck, you can try the following methods to troubleshoot the issue:

  1. Check Network Connection: Ensure that the network connection between all nodes in the TiDB cluster is normal. You can try using the ping command to check the connectivity between hosts to ensure there are no network issues.

  2. Check TiDB Cluster Status: Use the tiup cluster display <cluster-name> command to view the status of the TiDB cluster. Ensure that all components are running normally and there are no error messages.

  3. Check TiUP Version: Make sure you are using the latest version of the TiUP tool. You can use the tiup update command to update the TiUP tool.

  4. Check TiUP Configuration File: Check the TiUP configuration file ~/.tiup/config.yaml to ensure the configurations are correct.

The reason is that the new central control system cannot access the external network. After enabling the external network, it worked fine.

It seems that external network access for tiup can be disabled.

Cousin is correct…

The central control can mirror to the local source.
