We used 4 servers to form a cluster, and it has been running successfully for a while. After restarting this time, it prompts that tiup cannot be found when starting again.

  1. Did you use the wrong machine?
  2. Check if there are any tiup entries in the environment variables.
  3. Check if the /root/.tiup directory exists.

Did you forget to switch users? Generally, you need to switch to the tidb user to execute.

Check if the tiup file is missing?

Confirm whether the error reported by tiup is from the control machine.

Find the location of tiup, locate the directory path and try running it directly.

Is tiup available now?
