Note

  • You do not need to manually create the tidb user in the configuration file. The TiUP cluster component automatically creates the tidb user on the target machines. You can customize the user, or keep the user consistent with the control machine.
  • If you configure the deployment directory as a relative path, the cluster will be deployed in the home directory of the user.
