Database Development Tutorials, Guides & Insights

• MySQL treats connections from localhost (via Unix socket) and 127.0.0.1 (via TCP/IP) as distinct connections. By default, the root user may only have privileges for localhost, causing an "Access Denied" error when trying to connect from 127.0.0.1.

This tutorial explains how to grant privileges to the MySQL root user for connections over TCP/IP (127.0.0.1). By following these steps, you can resolve access denied errors and ensure smooth connections to your MySQL database for both local development and remote applications.

   GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION;

This grants the new root user full access to all databases and tables, as well as the ability to grant permissions to other users.
