# 登录MySQL数据库
D:\MySQL\bin>mysql -u root -p

mysql> use mysql;
mysql> update user set password=password("123456") where user="root";
mysql> flush privileges;
Copy after login

3、关闭以上两个窗口,启动MySQL服务

# 启动MySQL服务
C:\>sc start mysql
Copy after login

Linux下重置密码的操作与Windows下类似。

# 停止MySQL服务
[root@www ~]# /etc/init.d/mysql stop

# 以安全模式启动MySQL
[root@www ~]# /usr/local/mysql/bin/mysqld_safe --skip-grant-tables &
Copy after login
