How to 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) and delete all
4. query MySQL on drive C and delete all
5. just reinstall it.

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.
