MYSQL 修改root密码命令小结,需要的朋友可以参考下。

一、请问在win2K命令提示符下怎样更改mysql的root管理员密码?

>mysql -u root -p
Enter password: ******
mysql> use mysql;
mysql> update user set password=password('new_password') where user='root';

通过这种方法就可以直接修改密码了。至于在CMD下能否登陆MySQL,就要在Windows环境变量PATH中添加“C:\Program Files\MySQL\MySQL Server 5.0\bin;”(请改为你自己的安装路径)了。

二、MYSQL 修改root密码命令

cmd下切换到 mysql 安装目录

d:/mysql/bin
前提:mysql用户root密码为空.
输入 mysql -u root mysql
mysql> 状态下输入 update user set password=password('新密码') where user='root';
回显
Query OK, 0 rows affected (0.00 sec)
Rows matched: 2 Changed: 0 Warnings: 0
mysql> 状态下输入 FLUSH PRIVILEGES;
回显
Query OK, 0 rows affected (0.00 sec)
mysql> 状态下输入 quit
退出 sql

注意每个命令后都要加上一个分号 ";"
mysql 才开始执行该行命令
而第二个指令会让已载入记忆体的 mysql 系统资料库更新

重起 mysql .
停止MYSQL
net stop mysql
开始MYSQL
net start mysql
