To test Apache2 setup, open your browser and browse to the server hostname or IP address and you should see Apache2 default test page as shown below. When you see that, then Apache2 is working as expected.
Install MariaDB Database Server
MariaDB database server is a great place to start when looking at open source database servers to use with Magento. To install MariaDB run the commands below.
sudo apt-get install mariadb-server mariadb-client
After installing MariaDB, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.
Run these on Ubuntu 16.04 LTS
sudo systemctl stop mysql.service sudo systemctl start mysql.service sudo systemctl enable mysql.service
Run these on Ubuntu 17.10 and 18.04 LTS
sudo systemctl stop mariadb.service sudo systemctl start mariadb.service sudo systemctl enable mariadb.service
After that, run the commands below to secure MariaDB server by creating a root password and disallowing remote root access.
