Solve the Problem of MySQL reinstallation

 
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:
Www.2cto.com
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. Just install MySQL and show it unresponded, it is usually displayed that the 2 or 3 items in the last step of installing the MySQL program do not move. 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 ents 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.
Www.2cto.com was installed in the above method for one afternoon, but it still won't work. Finally, because my Server is Windows Server 2008 RC, I want to check whether it is compatible. My next question is the latest mysql5.5.28. So I removed the check when taking this step: then, find the program named mysqlinstanceconfig.exe under the binfile folder in the mysqlinstallation directory, right-click the property, such as setting: Double-click mysqlinstanceconfig.exe, and install it step by step!
