MariaDB is a multi-threaded and open-source database management system which will organize and provide access to databases where your site can store information. It is a replacement of MySQL and developed by some of the original developers of the MySQL. With the release of Debian 9, MySQL was replaced with MariaDB as the default database system. In this tutorial we will show you how to install MariaDB on Debian 10 Buster.
Install MariaDB on Debian 10
In this tutorial you will learn step by step how to install MariaDB on a Debian 10 server.
At first, you need Debian 9 server with a non-root sudo enabled user account.
By default, MariaDB version 10.3 is included on Debian 10 in the APT package repositories.
At first, update the package index on your server with apt.
sudo apt update
After that, install MariaDB server and client packages by by typing :
sudo apt install mariadb-server
It will start automatically MariaDB service.
Run below command to check MariaDB service status:
sudo systemctl status mariadb
It will show output as following :
● mariadb.service - MariaDB 10.3.15 database server Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled) Active: active (running) since Fri 2019-07-12 11:32:30 UTC; 8min ago Docs: man:mysqld(8) https://mariadb.com/kb/en/library/systemd/ Main PID: 4509 (mysqld) Status: "Taking your SQL requests now…" Tasks: 32 (limit: 4820) CGroup: /system.slice/mariadb.service 4509 /usr/sbin/mysqld
To increase security of MariaDB installation run the included security script. This will remove less secure default options such as root remote login and remove sample users. Run the below command :
At first, it will prompt you to enter current root user password. Next, it will ask you weather you want to change or set password for root. Press N and hit Enter key. After that it will prompt series of questions, press Y and hit Enter to accept the defaults for all the subsequent questions.
This will remove some anonymous users and the test database, disable remote root logins, and load these new rules so that MariaDB immediately respects the changes you have made.
Connect to MariaDB from the command line
You can also connect MariaDB server through the terminal as the root account by typing:
mysql -u root -p
You will be prompted to enter the root password. Enter root user password which you set at securing step.
Once you will enter correct password it will show MariaDB shell.
