During MySQL installation, the underlying encoding method was neglected and the default ASCII encoding format was used. As a result, the problem of Chinese conversion followed one after another. I wanted to uninstall MySQL and reinstall it, an error occurred while uninstalling the package. As a result, the package cannot be installed and cannot be installed after being found online for more than an hour.
Reinstalling the system is always a good solution, but who would like to do so :(
Later, I did not intend to find that the uninstallation was not completely caused by the uninstallation. The following describes how to unmount MySQL 5.1:
1. add and delete programs in the control panel to delete them (close MySQL service first, right-click my computer-Manage-Service)
2. Delete the my. ini file in the MySQL folder. If the file is backed up, delete all the folders directly.
3. Start-> Run-> Regedit. Check whether the registry has been deleted.
HKEY_LOCAL_MACHINE \ SYSTEM \ controlset001 \ Services \ Eventlog \ Application \ mysql directory Deletion
HKEY_LOCAL_MACHINE \ SYSTEM \ controlset002 \ Services \ Eventlog \ Application \ mysql directory Deletion
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Eventlog \ Application \ mysql directory deletion (I did not find the directory when I uninstalled it, and it was still completely uninstalled after I skipped it .)
4. This article is critical.
C: \ Documents ents and Settings \ All Users \ Application Data \ mysql
MySQL files must be deleted.
Note: The application data folder is hidden. To open a folder, choose menu bar tool> folder option> View> hide file and folder. All files and folders are displayed.
After completing the above four steps, restart OK! Install it again
