本来以前装过MySQL，但是密码忘了，在网上百度重置root密码方法，感觉很麻烦，就想着作死卸载重新装，然后就碰到了这个问题

然后一直卡在这个问题1，2个小时，在网上也百度了很多方法

结果还是一脸懵，真的是大部分方法都试过了，例如：自建的data文件夹；修改my.ini和my-default.ini配置文件等

发现还是没有用，后来还是在这里突然想起干嘛不看自己的日志，不就知道原因了吗

当时抱着试一试的心态

进入DOS界面，到MySQL文件夹下输入mysqld --console

C:\Windows\system32>cd C:\Program Files\MySQL\MySQL Server 5.7\bin

看到错误，一下想起了自己做的死，简直泪流满面啊，

IP被另一个服务占用了，然后高兴坏了，小手一点，然后困扰了我一个多小时问题就解决了。
