Webmin is a Web Interface application written in perl language used for Graphical Configuration of Linux Operating System. It is possible to do all that configuration through webmin that you are doing through terminal. Those peoples who founds Linux is a difficult operating system to configure due to it’s terminal and command line interface webmin is useful for them.

Follow the below Steps to Install webmin in Linux

Install Webmin .rpm based Package

It is recommended to update all packages and dependencies before any new package installation. But It’s not necessary and totally upon you. You can use below command to update you Linux System.

[root@localhost ~]# yum update # Update all Packages & Repositories

Download the webmin .rpm based package using below command.

[root@localhost app]# wget http://prdownloads.sourceforge.net/webadmin/webmin-1.840-1.noarch.rpm # Download Webmin .rpm Based Package --2017-06-15 09:28:58-- http://prdownloads.sourceforge.net/webadmin/webmin-1.840-1.noarch.rpm Resolving prdownloads.sourceforge.net... 216.34.181.59 Connecting to prdownloads.sourceforge.net|216.34.181.59|:80... connected.

As you can see below we have latest version of webmin package.

[root@localhost app]# ls webmin-1.840-1.noarch.rpm

Now we can go ahead and install webmin package. While installing the webmin package it’s asked for some dependencies as you can see on sample output below. So before we start the installation of webmin we have to install required dependencies.

[root@localhost app]# rpm -ivh webmin-1.840-1.noarch.rpm warning: webmin-1.840-1.noarch.rpm: Header V3 DSA/SHA1 Signature, key ID 11f63c51: NOKEY error: Failed dependencies: perl(Net::SSLeay) is needed by webmin-1.840-1.noarch perl(Encode::Detect) is needed by webmin-1.840-1.noarch

Follow the below command to install the required dependencies for webmin.

[root@localhost ~]# yum -y install perl-Encode-Detect perl-Net-SSLeay # Install dependencies of Webmin Loaded plugins: fastestmirror, refresh-packagekit, security Determining fastest mirrors * base: mirror.nbrc.ac.in * extras: mirrors.viethosting.com * updates: mirrors.viethosting.com base | 3.7 kB 00:00 extras | 3.4 kB 00:00 extras/primary_db | 29 kB 00:00 updates | 3.4 kB 00:00 updates/primary_db | 1.4 MB 00:15 Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package perl-Encode-Detect.x86_64 0:1.01-2.el6 will be installed ---> Package perl-Net-SSLeay.x86_64 0:1.35-10.el6_8.1 will be installed --> Finished Dependency Resolution Dependencies Resolved =================================================================================================================================== Package Arch Version Repository Size =================================================================================================================================== Installing: perl-Encode-Detect x86_64 1.01-2.el6 base 80 k perl-Net-SSLeay x86_64 1.35-10.el6_8.1 base 174 k Transaction Summary =================================================================================================================================== Install 2 Package(s) Total download size: 255 k Installed size: 781 k Downloading Packages: (1/2): perl-Encode-Detect-1.01-2.el6.x86_64.rpm | 80 kB 00:00 (2/2): perl-Net-SSLeay-1.35-10.el6_8.1.x86_64.rpm | 174 kB 00:00 ----------------------------------------------------------------------------------------------------------------------------------- Total 257 kB/s | 255 kB 00:00 warning: rpmts_HdrFromFdno: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 Importing GPG key 0xC105B9DE: Userid : CentOS-6 Key (CentOS 6 Official Signing Key) <centos-6-key@centos.org> Package: centos-release-6-5.el6.centos.11.1.x86_64 (@anaconda-CentOS-201311272149.x86_64/6.5) From : /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : perl-Encode-Detect-1.01-2.el6.x86_64 1/2 Installing : perl-Net-SSLeay-1.35-10.el6_8.1.x86_64 2/2 Verifying : perl-Net-SSLeay-1.35-10.el6_8.1.x86_64 1/2 Verifying : perl-Encode-Detect-1.01-2.el6.x86_64 2/2 Installed: perl-Encode-Detect.x86_64 0:1.01-2.el6 perl-Net-SSLeay.x86_64 0:1.35-10.el6_8.1 Complete!

So we have installed required dependencies for webmin. now we can go ahead and install webmin package using below command.

[root@localhost app]# rpm -ivh webmin-1.840-1.noarch.rpm # Install Webmin .rpm Package warning: webmin-1.840-1.noarch.rpm: Header V3 DSA/SHA1 Signature, key ID 11f63c51: NOKEY Preparing... ########################################### [100%] Operating system is CentOS Linux 1:webmin ########################################### [100%] Webmin install complete. You can now login to https://localhost.localdomain:10000/ as root with your root password.

Installation of webmin completed successfully. As you can see on able output we can access webmin web interface using the URL : http://localhost:10000 OR http://IP_ADDRESS:10000

To access the webmin from other system you have to bypass the webmin port i.e. 10000 from Linux Firewall (iptables). To do so just edit the /etc/sysconfig/iptables file and add the below Highlighted Line.

[root@localhost app]# nano /etc/sysconfig/iptables # Bypass the Webmin Port from Linux Firewall -A INPUT -p tcp -m tcp --dport 10000 -j ACCEPT

Then restart the iptables service using below command.

[root@localhost app]# /etc/init.d/iptables restart # Restart the IPtables Service iptables: Setting chains to policy ACCEPT: filter [ OK ] iptables: Flushing firewall rules: [ OK ] iptables: Unloading modules: [ OK ] iptables: Applying firewall rules: [ OK ]

As you can see below we have latest version wemin .tar based package.

[root@localhost app]# ls webmin-1.840.tar.gz

Now extract the package.

[root@localhost app]# tar -xzvf webmin-1.840.tar.gz # Extract the Webmin .tar based Package

Once you extract the .tar file you will get a directory named webmin-1.840.

[root@localhost app]# ls webmin-1.840 webmin-1.840.tar.gz [root@localhost app]# cd webmin-1.840

just go in to the extracted directory and run the setup.sh script. refer the command below.

Once you run the script system will ask for some settings (eg : Config file directory, Log file directory, Login name, Login password..etc..) that you have to answer as per your setup and requirement or just press ENTER to take default the settings.

[root@localhost webmin-1.840]# ./setup.sh # Install Webmin Package *********************************************************************** * Welcome to the Webmin setup script, version 1.840 * *********************************************************************** Webmin is a web-based interface that allows Unix-like operating systems and common Unix services to be easily administered.

The setup script needs to know : - What port to run the web server on.

Use your web browser to go to https://localhost.localdomain:10000/ and login with the name and password you entered previously. Because Webmin uses SSL for encryption only, the certificate it uses is not signed by one of the recognized CAs such as Verisign. When you first connect to the Webmin server, your browser will ask you if you want to accept the certificate presented, as it does not recognize the CA. Say yes.

To access the Webmin Web Access open your web browser and enter the below URL :

http://IP_ADDRESS_OF_YOUR_SYSTEM:10000 (Here my system’s IP Address is 192.168.0.103 where I installed the Webmin Service, so the URL would be https://192.168.0.103:10000)

The Uninstallation script of webmin is stored in /etc/webmin directory. So to Uninstall the webmin package refer the below command.

[root@localhost webmin-1.840]# /etc/webmin/uninstall.sh # Uninstall the Webmin Service Are you sure you want to uninstall Webmin?
