To Start With: What Do You Need?
To complete this process, you will require a working installation of the CentOS 7 operating system with root privileges. It is expected that a MariaDB server is already installed and running and you have read and applied the Managing a MariaDB database process for an understanding of permissions and how to test (local) database connections.
The Process
In our example, we want to access a MariaDB database server with the IP address 192.168.1.12 from a client computer in the same network, with the IP address 192.168.1.33. Please change appropriately to fit your needs:

After this, we configured which IP addresses were allowed to access our database server, which is done on a database level using the MariaDB shell.
