In view of the other information on the Internet is too miscellaneous, in this summary, hoping to help those who are equally confused friends!

about the installation of MySQL tutorial, there is an online step, the novice on the road-mysql installation, follow the installation on the line. But sometimes installing to the end will not prompt "APPLY Security Settings Error", let a person a little bit of mind.

In fact, the direct cause of the error is that when uninstalling MySQL does not completely delete the file, you must manually clear all the relevant files. In this note, My Computer system is Windows8.1, may be different system file directory path is not the same.

Workaround:
The first step: Remove the MySQL installation directory, generally C:\Program files directory.
The second step: delete the MySQL data storage directory, generally in the C:\ProgramData\MySQL directory (Note that this folder is hidden by default, to view the hidden items).
The third step: Delete the registry data, through Regedit, delete the following several files:

hkey_local_machine/system/controlset001/services/eventlog/applications/mysqlhkey_local_machine/system/ Currentcontrolset/services/eventlog/applications/mysql

Reinstall your MySQL program. After the installation is complete, you can check the service of the system, whether MySQL has been started, if not started, right-click, click Start (My Computer---management services and applications, services), find MySQL boot on the line.

hope to help everyone!
