1)如果您没有忘记密码的情况下,可以通过UPDATE直接编辑user表来修改密码:

进入数据库mysql -u root
mysql> use mysql;
mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';
mysql> FLUSH PRIVILEGES;
或者
 /etc/init.d/mysql stop
 /etc/init.d/mysql start


2)如果您已经忘记密码:
# /etc/init.d/mysql stop                                  1、结束当前正在运行的mysql进程。
# /usr/bin/mysqld_safe --skip-grant-tables    2、用mysql安全模式运行并跳过权限验证。
# mysql -u root                                              3、重开一个终端以root身份登录mysql。


mysql> use mysql;                                          4、修改root用户口令。
