Could not connect to the MariaDB - MySQL database

The error message "Could not connect to the MariaDB" can occur for a number of reasons. Some of the most common causes include:

  • The MariaDB server is not running.
  • The database user you are trying to connect with does not have the correct permissions.
  • You are using the wrong host, port, or socket information.
  • There is a network problem between your computer and the MariaDB server.

To troubleshoot this error, you can try the following steps:

1. Check to make sure that the MariaDB server is running. If you have access to the command line, you can do this by running the following command:

sudo service mariadb status


2. Check the permissions of the database user you are trying to connect with. You can do this by running the following command:

sudo mysql -u root -p

 

Once you are logged in to the MySQL shell, you can run the following command to see the permissions of the user:

SELECT user, host, password FROM mysql.user;


3. Check the host, port, and socket information you are using to connect to the MariaDB server. You can find this information in the MariaDB configuration file, which is typically located at /etc/my.cnf.


4. Check for network problems between your computer and the MariaDB server. You can do this by running a ping test to the server's IP address.


If you have tried all of these steps and you are still getting the error message, you may need to contact your hosting provider for assistance.

Here are some additional resources that you may find helpful:

All databases and username will have your username appended to the beginning to prevent your information from being overwritten by other users using the same names. Because of this you will also want to keep database and usernames short as some applications have problems with longer names.

Keep passwords simple to alpha-numeric. Don't include dots and special characters as some apps have problems with this.

Make sure you have added the username to the database and the correct permissions were selected before adding. This is typically the "all" setting.

Hostname will always be "localhost" unless you are trying to connect to the database remotely using an application such as MySQL Navigator.

When connecting remotely MariaDB / MySQL is accessible via the standard port of 3306.
