### 记一次重装mysql遇到的坑 ###

*  首先先卸载mysql
 *  清空注册表
 *  删除mysql的安装目录
 *  重装mysql

今天安装mysql的时候手贱卸载掉了想重装，结果再次重装的时候卡在了 start service 那里，后来上网搜索才知道需要删除mysql在注册表上面的信息才行。

# 首先先卸载mysql #

1、打开控制面板（cmd 运行control panel ）

2、选择类别，点击卸载程序

# 清空注册表 #

1、打开注册表（cmd 运行regedit ）

2、ctrl + f 或 “编辑–>查找”，输入mysql，查找下一个

搜索一会后，锁定到了对应的注册项，右键删除；然后F3（笔记本是fn+F3）或者编辑–>查找下一个，搜索到后进行删除，知道删除完为止。

# 删除mysql的安装目录 #

默认安装的目录在C盘C:\\Program Files下，讲MYSQL文件夹删除掉

# 重装mysql #

运行mysql的msi文件进行安装，到 start service 的时候提示：Mysql 错误：cannot create windows service  
**解决：**  
1、打开服务（cmd 运行services.msc）

2、找到mysql，停止掉它

3、在win10左下角输入cmd，右键管理员运行

4、输入 sc delete mysql，删除掉mysql的服务。

5、查看服务里面的MYSQL删除没有，然后再重新运行mysql的msi文件，安装成功。
