1、修改数据库密码

>mysql -u root -p
Enter password: ******
mysql> use mysql;
mysql> update user set password=password('new_password') 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：要切换到mysql数据库 就是use mysql命令
