安装MySQL的时候出现这个报错:a windows service with the name MYSQL already exists.Please uninstall this service correctly or choose a different name for the new service.
开始--运行--输入 regedit,删除残留的注册表信息HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services下面找到MySQL注册表信息把它整个删掉后,重装mysql成功了!
接着到regedit把注册表
HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Services/Eventlog/Applications/MySQL
HKEY_LOCAL_MACHINE/SYSTEM/ControlSet002/Services/Eventlog/Applications/MySQL
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Eventlog/Applications/MySQL
