Craft CMS Server Check
This script checks if a server meets the minimum requirements to run a Craft 3 installation.
You can upload the
server folder to your web server's public html folder and load
checkit.php from your browser
server anywhere on your server and execute
php checkit.php from the console to see the results.
If you supply credentials in
config/db.php to your database, then the script will perform some additional database checks as well.
