1, CMD command line to start or stop mysql, the system displays a message indicating that the service name is invalid

Net start = net start = net start = net start = net start = net start = net start = net start You can check whether the mysql service exists by right clicking on this computer – > Administration – > Services and Applications – > Services.

If not, go to the mysql installation directory bin folder and enter mysqld –install. If Service successfully install is displayed, the installation is successful. Net start mysql: net start mysql: net start mysql

2. The mysql service cannot be started due to an exception

Tried various solutions, finally shut down mysql process, restart success…

(The underlying cause of this problem is not yet understood, but the solution is recorded and will be updated later…)
