由于之前安装过MySQL,卸载重装之后,每次到最后一步,start server就无响应,原因在于之前的MySQL没有卸载干净。 卸载步骤: 1,到控制面板里面卸载mysql 2.到安装盘:\Program Files目录下把mysql目录删除 3.如果在其他盘还有设置目录也要删除,空目录也要删

由于之前安装过MySQL,卸载重装之后,每次到最后一步,start server就无响应,原因在于之前的MySQL没有卸载干净。

卸载步骤:

1,到控制面板里面卸载mysql

2.到安装盘:\Program Files目录下把mysql目录删除

3.如果在其他盘还有设置目录也要删除,空目录也要删除

4.到regedit修改注册表,删除:

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

5.一定要删除目录 C:\Documents and Settings\All Users\Application Data\MySQL 

由于目录C:\Documents and Settings\All Users\Application Data\MySQL 是受系统保护目录,所以要先修改用户权限进入该文件夹。


重新安装就安装成功了。
