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 Cacti installation:
The newly created database user (cactiuser) should have access to the mysql.time_zone_name Table. To do that, import the mysql_test_data_timezone.sql to mysql database:

Once the installation process is complete, you will have to restart all services to reflect the changes made:
Step 5. Accessing cacti.
