I uninstalled MySQL today and re-installed a new version. Which of the following is an error occurred while starting the MySQL service during configuration: "The MySQL service cannot be started on the local computer. Error 1067: the process was unexpectedly terminated. "After an hour on the internet, I modified my. ini and finally failed. In desperation, I backed up the configuration file under the MySQL installation directory as my. ini. bak, and delete my. INI, and then restart the MySQL Configuration Wizard from the Start Menu. After the configuration, the MySQL service is started, but there is a problem with the application. Check the error message, if MySQL is just uninstalled, the original data directory will not be deleted, so the original password is still valid. Click "Skip", cancel the operation, and configure it again, on the "set Root Password" Page, enter the original password in the password. The password must be the same as that in the previous version. Then click "execute", haha ......, Actually OK.
