How to install Webmin?

Step 1: First, you will need to login to SSH Client using your root account.

Then enter these four commands:

yum install wget -y
wget http://prdownloads.sourceforge.net/webadmin/webmin-1.941-1.noarch.rpm
yum -y install perl perl-Net-SSLeay openssl perl-IO-Tty perl-Encode-Detect perl-Data-Dumper unzip perl-Encode-Detect
rpm -U webmin-1.941-1.noarch.rpm

Note: Installation can take a few minutes and will depend on your server speed. Once it is complete, you will see a message with your Webmin admin URL.

Step 2: Next, open Webmin in a browser, https://ip-address here:10000

On CentOS 7/8, if the URL does not work, you need to open port 10000. You can do so by running this command:

firewall-cmd --zone=public --add-port=10000/tcp --permanent
firewall-cmd --reload

The Webmin Dashboard will open. The New Design of WebMin looks nice.
