Try to start and report an error:

Answer 1

This situation is more likely because there are problems with the path and permissions of the log file.

The landlord himself found the solution is to change the path of the log file to/home/<user>Absolute path.

Use~On behalf of home is an alias provided by the shell and can only be used in the shell.
