Be careful

• There is no need to manually create  tidb  user ,TiUP cluster The component will automatically create the user on the target host . You can customize the user , It can also be consistent with the users of the central control computer .
• If the deployment directory is configured as a relative path , It will be deployed in the user's home directory .
