After re-operating with Super Pipeline Manager, it prompts that the service cannot be started.
It is the same after configuring the environment variables and trying again. I try to start it through services.msc, but the result is also a prompt. I don’t know how to solve it?

I am using Xiaoniao Cloud Server. I had a similar problem when I installed MySQL before. This is the solution I found on the Internet at that time. I think it is quite useful. You can refer to it: 1. First, control Uninstall the names related to mysql one by one in the panel. 2. Then find the mysql installation directory and delete all mysql folders, even empty folders. 3. Open C:\ProgramData, find the MySQL folder, and delete it (a critical step). The C:\ProgramData directory is hidden by default. You cannot see this directory directly. You can directly search in the search box on the c drive. Copy the path C:\ProgramData to find the MySQL folder and delete it. 4. Query mysql in the registry (regedit) and delete all; cmd -> regedit1.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 5. Restart the computer after deletion 6. Reinstall (if the last installation was not deleted cleanly, the installation may fail, please be careful before installing again Check if it has been deleted
