  1. Check if it is a permission issue:
  1. First, check the firewall, network, and port occupancy, and check the network connectivity.

Was it normal during initialization?

Check if the tidb user has read and write permissions for /tmp.

Did you deploy using the tidb user or the root user?

Did you previously conduct deployment tests in that directory? Are there any residual files in the directory? You can specify a directory instead of using the default one and give it a try.

Hello, it was started by the root user, so there shouldn’t be any permission issues. The firewall is not enabled, and the port query shows it is not in use. It was started by the root user on the local machine, so it does not involve network connectivity with other machines.

Hello, does initialization refer to the step of tiup cluster deploy? There were no errors in this step. It was started using the root user, not the tidb user.

Hello, it is the root user.

Hello, I tried using tiup cluster destroy, cleared all the directories, but after re-executing, it’s still the same.

Could you please provide the configuration details of your local test machine, such as disk size, number of CPU cores, and memory size?
