Mysql – Grant permissions error on MySQL

MySQL

I'm new my MySQL admin from the command line and typically use Phpmyadmin or MySql workbench to admin machines. I'm getting a problem while trying to grant a user access to DBs and hoping I could get some help to figure it out.

    [root@server20039]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 21

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> GRANT ALL ON *.* TO 'maintenance'@'localhost' IDENTIFIED BY 'qwerty' WITH GRANT OPTION;
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Then I tried this and still got the same error

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'qwerty' WITH GRANT OPTION;

and this

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'
    IDENTIFIED BY PASSWORD 'qwerty'  
    WITH GRANT OPTION;
FLUSH PRIVILEGES;

I could really use a hand figuring this out!

Check user:

mysql> SELECT CURRENT_USER();
+----------------+
| CURRENT_USER() |
+----------------+
| root@localhost |
+----------------+
1 row in set (0.00 sec)

Check privileges:

mysql> SHOW GRANTS;
+----------------------------------------------------------------------------------------------------------------------------------------+
| Grants for root@localhost                                                                                                              |
+----------------------------------------------------------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY PASSWORD '*03465AB87C2B44D98228458669A91479C2BAAA6C' WITH GRANT OPTION |
| GRANT PROXY ON ''@'' TO 'root'@'localhost' WITH GRANT OPTION                                                                           |
+----------------------------------------------------------------------------------------------------------------------------------------+

If you have recently updated MySQL run: mysql_upgrade and then restart MySQL daemon.
