MySQL reinstallation troubleshooting _ MySQL

Solve the problem of MySQL reinstallation bitsCN.com

I recently encountered a problem of MySQL reinstallation at work. today I will record my solution process.

First of all, for some reason, I have to uninstall mysql and then reinstall mysql. no matter how I use the control panel to uninstall and delete programs or the security guard, I will encounter a problem, it is installed to a location like this. When server start is started, the program will not respond, and it will always die there:

As a result, I tried to find a solution everywhere on the internet. according to most people's statements, I tried not to do it. I died:

The installation of MySQL shows no response. generally, it shows that the 2 or 3 items in the last step of installing the MySQL program will not change.

This is generally because the MySQL database service item you have installed is occupied.
Solution:
One way: when you can install MySQL, the default service name is "MySQL" in this step. you only need to change this name.

Two methods: 1. uninstall MySQL 2. delete the installation directory and data storage directory 3. query mysql in the registry (regedit) 4. query MySQL on disk C, delete all 5. reinstall
Note that the registry cmd-> regedit
1. HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Services/Eventlog/Application/MySQL Directory
2. HKEY_LOCAL_MACHINE/SYSTEM/ControlSet002/Services/Eventlog/Application/MySQL Directory
3. HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Eventlog/Application/MySQL Directory
4. HKEY_LOCAL_MACHINE/SYSTEM/CurrentControl001t/Services/MYSQL Directory
5. HKEY_LOCAL_MACHINE/SYSTEM/CurrentControl002/Services/MYSQL Directory
6. HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/MYSQL Directory
7. delete the C:/Documents and Settings/All Users/Application Data/MySQL Directory
You can choose either of the above two methods. it is OK to reinstall the new MYSQL version.

Note: After the deletion is complete, you must restart the computer before installing it.

I installed it for one afternoon using the above method, but it still won't work.

Finally, because my Server is Windows Server 2008 RC

So I want to see if it is a compatibility issue. here is the latest mysql5.5.28.

So in this step, I removed the check:

Find the program named mysqlinstanceconfig.exe under the binfile folder in the mysqlinstallation directory, and right-click the property, as shown in settings:

Double-click mysqlinstanceconfig.exe!
