In this way, you can then drop or remove a database by using the following command: However, this command can be modified to invoke the need to check if a database name is already in use by using: CREATE DATABASE IF NOT EXISTS. For historical reasons and to keep MariaDB backward-compatible with the older server versions, the default character set is latin1 and latin1_swedish_ci, but for any modern databases, you should always prefer to use utf-8 instead as it is the most standard and compatible encoding for international character sets (non-English alphabets). A character set is how the characters are encoded in the database and a collation is a set of rules for comparing the characters in a character set. We also specified utf8 as the character set of our new database together with a utf8_general_ci collation. By doing this, we were then able to create a database with a simple SQL function called CREATE DATABASE, providing a custom name for the field. We started the process by accessing the MariaDB shell as the root user with the mysql command. So what did we learn from this experience?

This feature is signified by the MariaDB shell prompt: On successful login, you will be greeted with the MariaDB command-line interface.To begin, log in on your CentOS 7 server with any system user you like and type the following command in order to access the MariaDB server using the MariaDB shell with the main MariaDB administration user called root (use the password created in the previous process):.The MariaDB command-line tool supports executing commands in both the batch mode (reading from a file or standard input) and interactively (typing in statements and waiting for the results).

It is expected that a MariaDB server is already installed and running on your server. To complete this process, you will require a working installation of the CentOS 7 operating system. The shell provides you with complete control over your database server, and for this reason, it represents the perfect tool for you to start your MariaDB work.

MariaDB can be used in conjunction with a wide variety of graphical tools (for example, the free MySQL Workbench), but in situations where you simply need to create a database, provide an associated user, and assign the correct permissions, it is often useful to perform this task from the command line. In this process, we will learn how to create a new database and database user for the MariaDB server.
