Root account wont work in MySQL - mysql

Question

I am logged in as root in my MySQL database. I try to run the following commands:
mysql> GRANT ALL ON *.* TO 'root'#'%'
-> IDENTIFIED BY '[password]'
-> WITH GRANT OPTION;
ERROR 1045 (28000): Access denied for user 'root'#'%' (using password: YES)
mysql>
I get the following error:
ERROR 1045 (28000): Access denied for user 'root'#'%' (using password: YES)
Im assuming my root user isnt set up correctly. Any ideas?
Edit
mysql> show grants for root
-> ;

Answer 1

You might be logged into the database with an account named root, but the account you are in as does not have the correct privileges.
mysql> select user();
And follow that up with a:
mysql> select * from mysql.user\G
Look for the user and host columns to match exactly as the output. Look for grant_priv and it needs to say Y. More than likely there is additional root accounts without the grant_priv.
mysql> select * from mysql.user\G

When I enter the select * from mysql.user\G command, I get : ERROR 1142 (42000): SELECT command denied to user 'root'#'localhost' for table 'user' ERROR: No query specified
This means you're not logged in as 'root'#'%'. You're logged in as 'root'#'localhost', which are two different users. If you run SELECT USER(); as mentioned above, it will likely show you 'root'#'localhost'.
If you are logged in as 'root'#'localhost', you are logging in via local socket. Logging in through a TCP connection will get you access as 'root'#'%', which will then give you access to change grants based on the output you listed initially. To do so, login with:
mysql -u $user -p $pass -h 127.0.0.1
