MariaDB: Enable remote connections

To enable remote connections to a MariaDB server, you typically need to follow these steps:

  1. Configure MariaDB to Listen on All Interfaces: By default, MariaDB might be configured to listen only on the localhost (127.0.0.1), which means it will not accept connections from remote machines. To change this, you need to edit the MariaDB configuration file.Locate the MariaDB configuration file, which is usually named my.cnf or my.ini depending on your operating system and MariaDB version.Add or modify the bind-address parameter in the [mysqld] section of the configuration file to listen on all interfaces:[mysqld] bind-address = 0.0.0.0
  2. Grant Remote Access Privileges: After configuring MariaDB to listen on all interfaces, you need to grant remote access privileges to the user account you want to use for remote connections. By default, remote access is not granted for security reasons.Connect to your MariaDB server using a MySQL client such as mysql or phpMyAdmin:bashCopy codemysql -u username -p Replace username with your MySQL username.Then, run the following SQL command to grant remote access to the user. Replace remote_user with the actual username and remote_host with the IP address or hostname of the remote machine:GRANT ALL PRIVILEGES ON *.* TO 'remote_user'@'remote_host' IDENTIFIED BY 'password' WITH GRANT OPTION; Replace 'password' with the password for the user account.Note: Using ALL PRIVILEGES is quite permissive. You may want to limit the privileges to the specific databases or tables the user needs access to.
  3. Firewall Configuration: Ensure that your firewall allows incoming connections on the MariaDB port (usually 3306). You might need to open this port if it’s blocked.
  4. Restart MariaDB: After making changes to the configuration file, restart the MariaDB service to apply the changes.sudo systemctl restart mariadb Use the appropriate command for your operating system if you’re not using systemd.

After following these steps, your MariaDB server should be configured to accept remote connections from the specified user account. Make sure to consider security implications and follow best practices when enabling remote access.
