mysql_secure_installation

Next we will need to log in to the MariaDB console and create a database for the Attendize. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Attendize installation:

MariaDB [(none)]> CREATE DATABASE attendize;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON attendize.* TO 'attendize'@'localhost' IDENTIFIED BY 'strongpassword';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> \q

Now sometime we may want to change some settings (for example, the port, and root login permission) . This can be done by editing the configuration file via command:

nano /etc/ssh/sshd_config

The first thing you may want to do is to change the default SSH listening port. Open the file and locate the line that specifies the listening port:

Port 22

Change it to something else. For example, to 323:

Port 323

Save the file and close it. Then restart the service for the changes to take effect:

systemctl restart sshd.service
