Crucial provides Webmin control panel  as an alternative option to Cpanel/WHM with its Linux VPS server. For installing Webmin you need to have root SSH access to your Linux server.

Installation of Webmin on CentOS 5

First run this command to update the system’s package

# yum update

Then you need to install the Perl module Net::SSLeay

# yum -y install perl-Net-SSLeay wget

Download and install webmin

# wget http://prdownloads.sourceforge.net/webadmin/webmin-1.590-1.noarch.rpm

or

# wget http://sourceforge.net/projects/webadmin/files/webmin/1.590/webmin-1.590-1.noarch.rpm/

then run this command to install webmin

# rpm -Uvh webmin-1.590-1.noarch.rpm

It will install Webmin and you can access it using https://[serverIP]:10000

Webmin installation on Ubuntu 9 or Debian 5 using(.deb) Packages

Before installing any packages it’s always a good idea to get a full up to date list of packages. This can be done by running the follow command

# apt-get update

If you are getting error of repositories, Then you can replace the source list with the new repositories URLs:

# vi /etc/apt/sources.list

For example:

deb http://old-releases.ubuntu.com/ubuntu/ jaunty main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ jaunty-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ jaunty-security main restricted universe multiverse

Before downloading or installing the .deb Webmin package, run the following command to install the tool wget for downloading packages from the internet.

# apt-get install wget

The next command will install some perl-related libraries required by webmin.

# apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl

Run the following command

# apt-get update

Now you can download the Webmin .deb package

# wget http://sourceforge.net/projects/webadmin/files/webmin/1.590/webmin_1.590_all.deb/download

Install the Debian package with dpkg, not Aptitude

# dpkg -i webmin_1.590_all.deb

This will give you an error like this:

——————————SNIP————————–
dpkg: dependency problems prevent configuration of webmin:
webmin depends on libnet-ssleay-perl; however:
Package libnet-ssleay-perl is not installed.
webmin depends on libauthen-pam-perl; however:
Package libauthen-pam-perl is not installed.
webmin depends on libio-pty-perl; however:
Package libio-pty-perl is not installed.
webmin depends on apt-show-versions; however:
Package apt-show-versions is not installed.
dpkg: error processing webmin (–install):
dependency problems – leaving unconfigured
Errors were encountered while processing:
webmin
—————————————————————

This is good, we want it to error out, there is a little known function of apt-deb that when you have dependencies missing, it will add it to a fix-deps database internally in aptitude system, so that we can issue a command to do all the installation for us!

# apt-get -f install

After the successful installation of Webmin, You will get a message with the following URL in order to access the Webmin control panel.

This URL will be in the form of

“https://hostname:10000” (where “host name” is the host name of your Linux server)

You can use your server IP instead of host name in the above URL to access Webmin Control Panel.
