Webmin Installation and Configuration in Ubuntu Linux

Webmin is a web-based interface for system administration for Unix. Using any browser that supports tables and forms (and Java for the File Manager module), you can setup user accounts, Apache, DNS, file sharing and so on.
Webmin consists of a simple web server, and a number of CGI programs which directly update system files like /etc/inetd.conf and /etc/passwd. The web server and all CGI programs are written in Perl version 5, and use no non-standard Perl modules.
Installing Webmin in Ubuntu
You can use the above procedure but if you want to install latest version you can download from webmin site download section


Prerequisites
Perl 5 interpreter and libnet-ssleay-perl
sudo apt-get install perl5 libnet-ssleay-perl
Now you need to download the latest webmin from the above downloadlink
Download ‘webmin-1.310.tar.gz’ (at the time of writing) to some location in your machine ex:- /usr/local/src
wget http://prdownloads.sourceforge.net/webadmin/webmin-1.310.tar.gz
cd /usr/local/src
sudo tar xzvf webmin-1.310.tar.gz
cd webmin-1.310
sudo sh setup.sh
This will start the installation and now it will prompt for several questions answer them as follows
Config file directory [/etc/webmin]:
Leave as default, or change as you wish
Log file directory [/var/webmin]:
Leave as default, or change as you wish
Full path to perl (default /usr/bin/perl):
Leave as default, or change as you wish
Operating system:
Enter ’6′
Version:
Enter ’6′
Web server port (default 10000):
This is where you can start to make webmin more secure then the standard install you get with apt-get, Synaptic, or RPM. Leave as default or change it to what ever port you want.
Login name (default admin):
It is ‘admin’, so you can leave it as that, or put in any name that you like.
Login password:
By creating the user above and giving it a password, you have now made it so you will not need to log into webmin with root.
Password again:
enter your password again
If you did not install ‘libnet-ssleay-perl’ you will get the following message:
‘The Perl SSLeay library is not installed. SSL not available.’ You can continue with the install, but it would be more secure if you install sslrelay.
Use SSL (y/n):y
Choose yes here
Start Webmin at boot time (y/n):y
select here y
At this point it is going to configure things, install things, and create thingsxn--
It will then tell you that you can log in to https://hostipaddress:10000 and to accept the certificate.
Webmin User Password Change
If you want to change root password in webmin use this included Perl script:
sudo /usr/share/webmin/changepass.pl /etc/webmin root
If you want to install any standard modules you can download from here
If you want to install third party modules you can download from here
