Hello,

I would recommend following this step by step tutorial here on how to install and configure Laravel on Ubuntu 18.04:

https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-laravel-with-lemp-on-ubuntu-18-04

Once you have everything setup you can deploy your Laravel code either by pulling it from git or uploading it from your local PC via SFTP.

If you decide to use SFTP you can follow the steps here on how to do that:

Hope that this helps! Let me know if you have any questions!
Regards,
Bobby
