6、运行mysql

以管理员身份运行cmd，win10菜单栏里找到

依次执行命令：mysqld --install

　　　　　　    mysqld --initialize

 　　　　　　   net startt mysql

7、登录mysql 

　　mysql -uroot -p

 刚开始时，你随机输入会提示错误，不要慌。去我们刚才配置的data目录下找到一个.err的文件

 输入密码后就成功登录了。

8、修改mysql密码

　　　1）如果你此时进入到mysql中，使用exit退出

　　　2）net stop mysql 停止mysql服务

　　    3）mysqld --skip-grant-tables 使用无验证方式启动mysql服务

　　    4）使用管理员权限打开新的cmd命令行窗口，输入mysql  你就可以无密码进入到mysql中

　　　 5）use mysql   

　　     6）UPDATE user SET authentication_string = PASSWORD(‘新密码‘) WHERE user = ‘root‘;

再次登录使用设置的新密码就可以了！

 希望能够帮到大家！！！
