MySQL service cannot be started automatically

I don't know when to start.
The MySQL service on the computer cannot be started automatically.
Every time you want to use a data warehouse, you must run mysqld-nt.exe in the bindirectory.
Or at the command prompt, run the following command:
Very troublesome
I thought of the control panel --> the MySQL service is automatically started in the service.
But I didn't expect any MySQL service to exist.
At the command prompt mysqld-NT -- install
Register the service and go to the control panel --> service to set the MySQL service to automatically start.
Restart a computer
OK
