Adding Webmin to a fresh CentOS 7 Box

May 11, 2019

As a quick refresh from an earlier post, I'm going to use a new CentOS image with Webmin as the control panel of choice.

Happily, the only thing that's changed in the documentation is the way the gpg key is imported - documentation is here:

So, on a fresh CentOS 7 1901-01 box on AWS, let's begin.

# Update all base packages
sudo yum -y update
# Install nano (my preferred text editor)
sudo yum -y install nano
# Edit the /etc/yum.repos.d/webmin.repo file
sudo nano /etc/yum.repos.d/webmin.repo

Copy in the snippet below, then exit and save (Ctrl + X, then Y and Enter).

name=Webmin Distribution Neutral

This differs from a post in 2017 on adding Webmin as the gpgkey is captured here rather than imported separately.

The resulting dependencies are included here for reference:
