Installing MariaDB on Ubuntu 18.04

MariaDB is an open-source, community-developed relational database management system. It is a drop-in replacement for MySQL and offers improved performance, scalability, and security features.

To install MariaDB on Ubuntu 18.04, follow these steps:

1. Update the package index on your system:
   sudo apt update
2. Install MariaDB:
   sudo apt install mariadb-server
3. During the installation process, you will be prompted to set a password for the MariaDB root user. Enter a secure password and remember it.
4. Start the MariaDB service and enable it to start on boot:
   sudo systemctl start mariadb
sudo systemctl enable mariadb
5. Secure your MariaDB installation by running the following command:
   sudo mysql_secure_installation
6. Answer the prompted questions to secure your installation. The recommended options are typically to set a root password, remove anonymous users, disallow root login remotely, remove test databases, and reload privileges.
7. You can now access MariaDB using the root user and the password you set during the installation process.

After the successful installation, you can start creating databases and managing data with MariaDB. It is compatible with existing MySQL applications and tools, making it easy to migrate from MySQL to MariaDB if needed.
