In the previous steps, if the installation fails, or the installation stops midway, you must delete the installed files, otherwise the installation will fail. Today I wanted to take a screenshot during the installation, and then took a step back. When I installed it again, the installation was still unsuccessful. After restarting the computer, the installation still failed. After uninstalling the installation file, the installation can be performed.

2. Starting the server is abnormal

This abnormal error cannot be skipped directly, it can only be executed by Execute, but it is this error again. Either Back returns, or Cancel cancels.

However, during the installation, there was still starting the serveran abnormal error of ** **. In fact, at this point, the mysql community has been installed, and the next step is to save the previous configuration items, but the error of server startup is reported, so the previous configuration cannot be saved.

Find the installed mysql installer Community, click into it.

Win+R, enter regedit to run, enter the registry editor, press the path in the figure, find MySQL and delete the MySQL registry information .

Note: This account is checked before this position. Then change to the local system account, and check Allow the service to interact with the desktop. After the change, no error will be reported, and the exception of starting the server is indeed gone. I originally thought that I would change it back after the installation was complete and change it to this account, but what happened? I just can’t change it back. After the change, apply and then go back to the local system account option. It will still report an error when it is turned on for the first time every day, but it does not affect the use. Fortunately, it has not caused serious problems.
