Hello Everyone,

Today we are installing “webmin”

Being as a windows administrator working on Linux system it’s quite difficult to understand black screen. so you can do most of your work using webmin, it’s PHP based GUI application so can configure your linux system, can take system backup, manage your postfix server & do more.

“What is webmin”

Webmin is a web-based system configuration tool for Unix-like systems, although recent versions can also be installed and run on Windows.[4] With it, it is possible to configure operating system internals, such as users, disk quotas, services or configuration files, as well as modify and control open source apps, such as the Apache HTTP Server, PHP or MySQL.[5][6]

Webmin is largely based on Perl, running as its own process and web server. It defaults to TCP port 10000 for communicating, and can be configured to use SSL if OpenSSL is installed with additional required Perl Modules.

It is built around modules, which have an interface to the configuration files and the Webmin server. This makes it easy to add new functionality. Due to Webmin’s modular design, it is possible for anyone who is interested to write plugins for desktop configuration.

Webmin also allows for controlling many machines through a single interface, or seamless login on other webmin hosts on the same subnet or LAN.

Let’s start webmin installation

I already install one centos 6.4 OS

First command should be

Yum install update

For debian & ubuntu

Apt-get install update

Webmin RPM available on http://www.webmin.com

Or you can download it using wget command

You have to install wget

Yum install wget

cd /opt

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

[root@mail opt]# wget http://www.webmin.com/jcameron-key.asc
