MariaDB

MariaDB is a relational database.
It is free, the source code is open, and it is popular
for providing data on web servers.

The official Debian repository contains MariaDB:

apt install mariadb-server mariadb-client

To have a secure setup of the installation, execute:

mysql_secure_installation

Open the SQL command prompt:

mysql -u root [-p]

Create a new user:

CREATE USER 'user'@'localhost' IDENTIFIED BY 'password';

Create a new database:

CREATE DATABASE mydb;

Allow the new user to access the created database:

GRANT ALL PRIVILEGES ON mydb.* TO 'user'@'localhost';
FLUSH PRIVILEGES;

Dump a database to an SQL script and compress it:

mysqldump -u user -p mydb | gzip > mydb.sql.gz

Decompress and execute the SQL script to restore the database:

zcat mydb.sql.gz | mysql -u user -p mydb

To access a MariaDB database from PHP, install the connector:

apt install php-mysql
