mysql数据库安装不了了！mysql最后一步安装不上！mysql就是安装不上！是不是很头疼，很伤脑筋，现在大家不用着急了，小编为大家整理了mysql安装失败的原因以及mysql安装失败的解决方法，抓紧来看看吧！

困难1：MySQL 5.1 安装过程中报apply security setting错误

1.卸载MySQL。

2.删除目录 C:\Documents and Settings\All Users\Application Data\MySQL。

3.重新安装MySQL就OK啦。

困难2：MySQL提示Could not start the service MySQL提示

安装mysql 5.1.33，在运行Server Instance Configuration wizard时的Execute configurattion步骤中的第三项Start Service进出错，错误提示为Could not start the service MySQL

分析：这种情况一般是因为装过mysql，卸载不干净造成的，卸载后重启后再重装。注意看下服务，如果未能卸载，可以用mysqld-nt -remove卸载。

具体方法如下：

1.查看服务中有没有mysql,如果有将该服务停掉。

2.在控制面板中运行添加删除程序，将mysql卸载。

3.卸载后打开注册表，查看HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services 下的键值，如果有相关mysql键值(mysql、mysqladmin)则删掉，即可。

4.重启，将mysql的安装残余目录删掉 (查看服务，此时服务中已没有mysql)。

5.重新安装mysql.安装后先不要运行Server Instance Configuration wizard，重启后在开始菜单中运行该向导，即可。

困难3：msyql安装到最后一步start service错误

1.到控制面板里面先把mysql删除。

2.到c盘C:\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

有的话，全部删除！（技巧：用F3循环查找“mysql”）5.如果任务管理器里有关mysql内容也删除。

5.把防火墙关了。

6.重新装mysql（这里我没有重启计算机）。

重装时候有必要的话,重启计算机，停用IIS，和删除temp里的临时文件。

实在不行的话，配置mysql时候,把mysql服务换个服务名。

以上就是在安装mysql时经常遇到的错误，更多相关内容请关注PHP中文网（www.php.cn）！
