Why Am I Getting 'Access Denied' When Granting MySQL Privileges as Root?
Nov 30, 2024 am 07:00 AMTroubleshooting "Access Denied" Error When Granting Privileges as Root
Encountering the error "Access denied for user 'root'@'localhost' (using password: YES)" when granting privileges can be frustrating, especially if you have confirmed the correct password and have sufficient privileges. This issue often arises when attempting to grant privileges on essential system tables, such as the mysql.users table.
The Root of the Problem:
MySQL's security architecture reserves certain tables, including the mysql.users table, for exclusive access by root-level users. Granting privileges on these tables to non-root users is prohibited as a security measure.
The Solution:
To successfully grant privileges while avoiding the access denied error, modify the grant statement to exclude the mysql.users table. Instead of ., use %.* to grant privileges on all other database objects:
GRANT ALL PRIVILEGES ON `%`.* TO '[user]'@'[hostname]' IDENTIFIED BY '[password]' WITH GRANT OPTION;
By excluding the mysql.users table, you respect the security restrictions and allow the grant operation to complete successfully.
