Granting All Privileges to 'root' in MySQL 8.0

In MySQL 8.0, granting all privileges to the 'root' user using the conventional method may encounter errors. This is because MySQL 8.0 has introduced changes in user management.

Error 1064:

When attempting to grant privileges using GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;, you may encounter error 1064. This error occurs because MySQL 8.0 no longer allows implicit user creation.

Error 1410:

Trying to grant privileges with GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION; can also result in error 1410. This error indicates that you are not authorized to create a user with the GRANT option.

Resolution:

To grant all privileges to 'root' in MySQL 8.0, you need to follow these steps:

1. Create the user using CREATE USER 'root'@'%' IDENTIFIED BY 'PASSWORD';.
2. Grant the privileges using GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;.
3. Refresh the privileges to apply the changes using FLUSH PRIVILEGES;.

Caution:

The GRANT OPTION allows the user to grant privileges to other users. While convenient, it can pose security risks. Consider carefully before granting this option to any user.
