It appears that you are correctly trying to install Moodle from scratch.
Have you also read the instructions? https://docs.moodle.org/402/en/Installing_Moodle
Do you know that your server meets all of Moodle's requirements?
Do you know that your website, unikrew.org, is working? Try putting a simple HTML web page there and see if it shows. When I go to unikrew.org/, nothing is showing. Try putting this "info.php" file into your web. Then go to unikrew.org/info.php, it should show your PHP configuration.
