The goal of this tutorial is to install and run PHPmyAdmin 5.1 on a Mac using Big Sur as Operative System. There are several ways to install PHPmyAdmin on a Mac, and from my perspective, the easiest way to do so is by using MAMP, which is a free Apache or Ngnix web server app that will spin a virtual instance of a web server in your local computer, which you can access through a local browser by pointing it to http://127.0.0.1:8888 or http://localhost:8888. Note that “local” means in your own computer. Apache an d Ngnix uses what they call a “public folder”, which is the directory located at /var/www/html for Apache and /usr/local/nginx/html for Ngnix, and any files placed there will be executed when you go to http://127.0.0.1:8888 or http://localhost:8888.
Open your browser and point it to http://127.0.0.1:8888 and you will see the PHPmyadmin screen, indicating that you did everything allright.
