MYSQL实例4、在解压目录D:Program Filesmysql-5.7.14-winx64下新建data文件(不用在文件夹做其他操作)

MYSQL实例5、以管理员身份进入cmd界面(必须是管理员)

MYSQL实例6、切换至mysql解压目录bin下,初始化data目录

MYSQL实例输入命令：mysqld --initialize-insecure (生成无密码的root用户)

MYSQL实例或：mysqld --initialize(生成带随机密码的root用户)

MYSQL实例7、初始化完成后启动mysql服务

MYSQL实例输入命令：net start mysql

MYSQL实例8、开始使用mysql

MYSQL实例输入命令：mysql -u root -p

MYSQL实例9、停止mysql服务

MYSQL实例输入命令：net stop mysql

MYSQL实例10、忘记root密码后如何登录

MYSQL实例　　101、 关闭正在运行的MySQL服务.

MYSQL实例　　10.2、 打开DOS窗口,转到mysqlbin目录.

MYSQL实例　　10.3、输入mysqld --skip-grant-tables 回车.--skip-grant-tables 的意思是启动MySQL服务的时候跳过权限表认证.

MYSQL实例　　10.4、再开一个DOS窗口(因为刚才那个DOS窗口已经不能动了),转到mysqlbin目录.

MYSQL实例　　10.5、输入mysql回车,如果成功,将出现MySQL提示符 >.

MYSQL实例　　10.6、连接权限数据库： use mysql; .

MYSQL实例　　10.7、改密码：update user set password=password("123") where user="root";(别忘了最后加分号) .

MYSQL实例　　10.8、刷新权限(必须步骤)：flush privileges;　.

MYSQL实例　　10.9、 退出 quit.

MYSQL实例　　10.10、注销系统,再进入,使用用户名root和刚才设置的新密码123登录.

MYSQL实例11、修改root用户密码

MYSQL实例5.7版本以前：

MYSQL实例
update user set authentication_string =password( 'root') where user = 'root;

MYSQL实例5.7版本以后：

MYSQL实例
update user set password=password( 'root') where user = 'root;
