修改完成  之后 在当前目录 按键盘 shift 左键：在此处打开命令窗口

输入 ：mysqld install

成功后 输入 ：net start mysql

1、mysql安装之后默认root密码是空

输入mysql -uroot 即可进去mysql

进去之后怎样设置初始密码呢：

执行

use mysql ;
update user set password=password("new_pass") where user="root"; 
flush privileges; 
exit ;

即可。

2、设置新密码跟1中一样

3、忘记密码

在my.ini中加入

[mysqld]
#跳过密码验证
#skip-name-resolve

然后在cmd中直接输入mysql -uroot 进去，然后执行1中的步骤
