Webmin installation on CentOS

There are two ways using which we can install Webmin on our CentOS machines

1- Using Webmin repository (YUM)

2- Using RPM package

Let's discuss both methods one by one,

1- Using Webmin repository (YUM)

To install Webmin using Yum, we will first create a repository for the Webmin, Create a file named ' webmin.repo' in ' /etc/yum.repos.d/' with the following repository information,

$ sudo vi /etc/yum.repos.d/webmin.repo

[Webmin]

name=Webmin Distribution Neutral

#baseurl=http://download.webmin.com/download/yum

mirrorlist=http://download.webmin.com/download/yum/mirrorlist

enabled=1

Next we need to install the GPG key with which the packages are signed. To install key, run the following command,

$ wget http://www.webmin.com/jcameron-key.asc

$ sudo rpm --import jcameron-key.asc

Now install the webmin,

$ sudo yum install webmin

All the dependencies will also be installed along with Webmin.

2- Using RPM package

If using RPM package to install Webmin, we firstly have to install some dependencies for Webmin. To install all the required dependencies, run the following

$ sudo yum install perl perl-Net-SSLeay openssl perl-IO-Tty perl-Encode-Detect

Than download the rpm with the following command ,

$ wget http://prdownloads.sourceforge.net/webadmin/webmin-1.850-1.noarch.rpm

& lastly install the downloaded rpm package with the following command,

$ sudo rpm -U webmin-1.850-1.noarch.rpm

This complete our installation of webmin on CentOS. We will now proceed for installation on Ubuntu system.

Webmin installation on Ubuntu

Like CentOS installation, there are two ways using which we can install Webmin on Ubuntu as well,

1- Using Webmin repository (APT)

2- Using DEB package

1- Using Webmin repository (APT)

To install Webmin using the official Webmin repository, open '/etc/apt/sources.list' file,

$ sudo nano /etc/apt/sources.list

& add the following line,

deb http://download.webmin.com/download/repository sarge contrib

Next install the GPG key with which package have been signed ,

$ cd /root

$ wget http://www.webmin.com/jcameron-key.asc

$ sudo apt-key add jcameron-key.asc

We are now ready to install Webmin on our Ubuntu sytems. To install Webmin, run the following commands,

$ sudo apt-get update

$ sudo apt-get install apt-transport-https

$ sudo apt-get install webmin

These commands will install Webmin along with all the dependencies required.

2- Using DEB package

While installing Webmin using the .deb packages, firstly install all the dependencies. Open terminal & execute the following command to install all the dependencies requried by Webmin,

$ sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python

Once the dependencies have been installed, download the Webmin .deb package using the following command,

$ wget http://prdownloads.sourceforge.net/webadmin/webmin_1.850_all.deb

& than install it,

$ sudo dpkg --install webmin_1.850_all.deb

Starting the service & accessing it

Now after the installation has been complete, we will start the service & enable it at boot time,

$ sudo service webmin start           OR             sudo systemctl start webmin

$ sudo chkconfig webmin on           OR             sudo systemctl enable webmin

Once the Webmin is up, we can access it using the Web browser with the following URL,

https://localhost or IP address:10000

Default user name for Webmin is 'root' & password is 'password'. Also we might an SSL warning while accessing the webmin portal for first time as webmin uses a self-signed certificate which gives warning , but we can add exception for it. Once logged in, we can use the Webmin to administer our server with a nice & clean GUI.

Our tutorial is now complete, in our future tutorial we will learn to add modules to Webmin. For now if facing any trouble or have any query , please leave them in the comment box below & we will surely address them.
