MySQL: Enabling Universal Remote Connections
MySQL differs from SQL Server in its approach to remote database access. While SQL Server allows developers to connect remotely with credentials, MySQL requires additional configuration for each remote connection. This article aims to clarify the process of enabling universal remote connections, similar to what is offered by SQL Server.
The command that achieves this is:
GRANT ALL ON *.* to user@'%' IDENTIFIED BY 'password';
However, MySQL documentation notes that another MySQL account for the same user must be created on the localhost to avoid conflicts with the anonymous account created by mysql_install_db. Thus, for successful remote access from any server, two accounts must be created:
GRANT ALL ON *.* to user@localhost IDENTIFIED BY 'password';
GRANT ALL ON *.* to user@'%' IDENTIFIED BY 'password';
This ensures that the user has both a localhost and universal access account. The wildcard character '%' in the host field permits connections from any host.
While granting universal access can be convenient, it is important to consider its potential security implications. Ensure that appropriate security measures, such as firewalls and strong passwords, are in place to protect your database. Additionally, consider implementing role-based access control to limit user permissions to only the data and functionality they require.
