解决ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

登录Mysql的时候提示没有权限登录, 一定是密码不对, 但是又不记得密码了. 那么重置下root密码吧

/etc/init.d/mysql stop

mysqld_safe --skip-grant-tables &

mysql -u root
Setup new MySQL root user password

use mysql;
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
flush privileges;

修改密码的时候出现的如下错误

错误描述：

mysql> grant all on cactidb.* to dbuser@'localhost' identified by '123';

ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

解决方法：

先刷新一下权限表。

mysql> flush privileges;

Query OK, 0 rows affected (0.01 sec)

mysql> grant all on cactidb.* to dbuser@'localhost' identified by '123';

Query OK, 0 rows affected (0.00 sec)
