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　　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MysqL\bin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) .
