MySQL ERROR 1410, commonly encountered as ERROR 1410 (42000): You are not allowed to create a user with GRANT, occurs when a user attempts to create another user with administrative privileges but lacks the required permissions. This error is primarily related to improper use of the GRANT statement, inadequate privileges, or changes in MySQL‘s user management policies.
This documentation explains the causes of MySQL ERROR 1410, provides detailed troubleshooting steps, and outlines best practices to avoid similar issues in the future.
TL;DR
- Cause: The user issuing the
GRANTstatement does not have sufficient privileges to assign the specified privileges or create users with administrative rights. - MySQL 8.0 and later: Starting MySQL 8.0 onwards, it is no longer possible to create a user directly from the GRANT command. The user must be created first before GRANTing privileges.
- Solution: Ensure the issuing user has the
CREATE USERandGRANT OPTIONprivileges, and verify the MySQL version’s privilege requirements. - Example Fix:
GRANT CREATE USER, GRANT OPTION ON *.* TO 'admin_user'@'localhost'; For MySQL 8.0+:
CREATE USER 'new_user'@'localhost' IDENTIFIED BY 'password';
GRANT SELECT, INSERT ON `db_name`.* TO 'new_user'@'localhost'; Understanding MySQL ERROR 1410
In MySQL, user privileges and roles are managed using the GRANT statement. ERROR 1410 is raised when a user without the GRANT OPTION privilege attempts to assign privileges to another user. This restriction prevents privilege escalation and enhances database security.
Causes of MySQL ERROR 1410
- Changes in MySQL Version:
- MySQL 8.0 introduced enhanced privilege management, making older practices incompatible or restricted.
- Insufficient Privileges:
- The user executing the
GRANTstatement does not have theGRANT OPTIONprivilege or lacks sufficient privileges to create new users.
- The user executing the
- Misconfigured Privilege Hierarchy:
- MySQL enforces strict privilege checks to ensure that only users with appropriate roles can delegate privileges.
Steps to Troubleshoot MySQL ERROR 1410
Use the CREATE USER Command Separately
In MySQL 8.0 and later, creating users and assigning privileges are often handled as separate operations.
Example:
CREATE USER 'new_user'@'localhost' IDENTIFIED BY 'password';
GRANT SELECT, INSERT ON `db_name`.* TO 'new_user'@'localhost'; Verify the Privileges of the Current User
Check the privileges assigned to the user executing the GRANT statement.
Command:
SHOW GRANTS FOR 'current_user'@'localhost'; Example Output:
GRANT USAGE ON *.* TO 'current_user'@'localhost';
GRANT SELECT ON `db_name`.* TO 'current_user'@'localhost';Ensure the user has the CREATE USER and GRANT OPTION privileges.
Assign Necessary Privileges
If the user lacks privileges, assign the required permissions using a privileged account.
Example Command:
GRANT CREATE USER, GRANT OPTION ON *.* TO 'current_user'@'localhost'; After granting privileges, flush the privileges table to apply changes:
FLUSH PRIVILEGES; Example Scenarios
1: Fixing Privilege Escalation Errors
Issue: A non-privileged user attempts to grant access to a new user.
Fix: Log in as a privileged user and grant appropriate permissions:
GRANT CREATE USER, GRANT OPTION ON *.* TO 'admin_user'@'localhost';
FLUSH PRIVILEGES; 2: Migrating to MySQL 8.0
Issue: The GRANT statement fails after upgrading to MySQL 8.0.
Fix: Modify the workflow to separate user creation and privilege assignment:
CREATE USER 'new_user'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON `db_name`.* TO 'new_user'@'localhost'; Common Issues and Troubleshooting MySQL ERROR 1410
Cannot Grant Global Privileges:
- Ensure the user has
GRANT OPTIONandSUPERprivileges for global-level grants.
FLUSH PRIVILEGES Not Applied:
- Forgetting to flush privileges may cause privileges not to take effect immediately.
Role Mismanagement:
- Improper role assignments may restrict privileges unintentionally.
