Linux MySQL 密码修改
1)如果没有忘记密码
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
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> update user set Password = PASSWORD('root') where User ='root';
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 0
mysql> exit
# /etc/init.d/mysql restart
5、结束mysql安全模式,用正常模式运行mysql
mysql> update mysql.user set password=PASSWORD('新密码') where User='root';
6、试试你新修改的口令
mysql> flush privileges;
mysql> quit
