How do I install and setup phpMyAdmin on a LAMP Droplet with Virtual Hosts

Original question here

I am trying to add phpMyAdmin to a droplet I am trying to follow this tutorial the tutorial is written for Ubuntu 16.04 I run 18.04.

I have currently

• Installed LAMP stack
• Added SSH key
• Enabled HTTPS: https://www.digitalocean.com/docs/marketplace/lamp/
• Setup a virtual host: https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-ubuntu-16-04

Besides the above, I have run this in the terminal

• sudo apt-get update
• sudo do-release-upgrade
• apt-get upgrade
• apt-get dist-upgrade

I am now trying to install phpMyAdmin from this tutorial

The problem occurs when I run:

sudo phpenmod mcrypt 

It gives me this error: Module mcrypt ini file doesn’t exist under /etc/php/7.2/mods-available

If I run sudo phpenmod mbstringnothing happens.

So I can’t get any further with the tutorial

This person have/had the same problem as me and one guy reply to him and said:

“If you installed it in a different way or have multiple VirtualHosts, then we might need to do a little adjusting to get it running.”

The thing is, this tutorial encouraged me to add VirtualHosts so I did that following this tutorial as I also mentioned above, but now I have no idea on how to proceed and install phpMyAdmin on one of the virtual host’s websites
