Webmin – A Web Based System Administration Tool for Linux

Webmin is an open-source web-based system configuration tool for Linux system administration. With the help of this tool, we can manage internal system configuration such as setting up user accounts, disk quotas, services configuration like Apache, DNS, PHP, MySQL, file sharing, and much more.

Webmin application is based on Perl module and it uses TCP port 10000 with OpenSSL library for communicating via browser.

Some of the things you can do with Webmin are:

  • Create, edit and delete user accounts on your system.
  • Share Files and Directories with other Linux systems via the NFS protocol.
  • Set up Disk Quotas to manage the amount of disk space available to users.
  • Install, view, and delete software packages on the system.
  • Change system’s IP address, DNS settings, and routing configuration.
  • Set up a Linux Firewall to secure your system.
  • Create and configure virtual hosts for the Apache Webserver.
  • Manage databases, tables, and fields in a MySQL or PostgreSQL database server.
  • Share files and directories with Windows systems via the Samba file sharing.

In this article, you will learn how to install the latest version of the Webmin system administration tool in Linux systems.

Installing Webmin Control Panel in Linux

We are using the Webmin repository for installing the latest Webmin tool with their required dependencies and we also receive up-to-date automatic updates of Webmin via repository.

Install Webmin in RHEL Systems

On RHEL-based distributions, such as Fedora, CentOS, Rocky & AlmaLinux, you need to add and enable Webmin repository, do to this create a file called /etc/yum.repos.d/webmin.repo and add the following lines to it as a root user.

# vi /etc/yum.repos.d/webmin.repo
name=Webmin Distribution Neutral

You should also download and install the GPG key with which the packages are signed, with the commands:

# wget https://download.webmin.com/jcameron-key.asc
# rpm --import jcameron-key.asc

You will now be able to install Webmin with the commands:

# yum install webmin
Install Webmin in RHEL Systems
Install Webmin in RHEL Systems

Install Webmin in Debian Systems

Similarly, you need to add and enable Webmin APT repository to the /etc/apt/sources.list file on your Debian systems such as Ubuntu and Mint.

$ sudo nano /etc/apt/sources.list

Add the following line at the bottom of the file. Save and close it.

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

Next, import and install GPG Key for installing signed packages for Webmin.

$ wget https://download.webmin.com/jcameron-key.asc
$ sudo apt-key add jcameron-key.asc    

On Debian 11 and Ubuntu 22.04 or higher, the commands are :

$ wget https://download.webmin.com/jcameron-key.asc
$ sudo cat jcameron-key.asc | gpg --dearmor > /etc/apt/trusted.gpg.d/jcameron-key.gpg

You will now be able to install Webmin with the commands:

$ sudo apt-get install apt-transport-https
$ sudo apt-get update
$ sudo apt-get install webmin

Starting Webmin in Linux

Run the following commands to start the service.

------------------- [on RedHat based systems] -------------------
# /etc/init.d/webmin start
# /etc/init.d/webmin status
Start Webmin in CentOS
Start Webmin on RedHat Systems
------------------- [on Debian based systems] -------------------

$ sudo /etc/init.d/webmin start
$ sudo /etc/init.d/webmin status
Start Webmin in Ubuntu
Start Webmin on Debian Systems

Step 3: Accessing Webmin Control Panel

By default Webmin runs on port 10000, so we need to open the Webmin port on our firewall to access it. The easiest way to open the port on the firewall is using the following commands.

------------------- [On FirewallD] -------------------

# firewall-cmd --add-port=10000/tcp
# firewall-cmd --reload
------------------- [On UFW] -------------------

$ sudo ufw allow 10000
------------------- [On IPtables] -------------------

# iptables -A INPUT -p tcp -m tcp --dport 10000 -j ACCEPT
# service iptables save
# /etc/init.d/iptables restart

Now we should be able to access and login to Webmin using URL http://localhost:10000/ and enter the username as root and password (current root password), for remote access just replace localhost with your remote IP address.

  1. Hi Ravi,

    Same here, followed instructions to a tee and not working. Using Centos 8.


    not connecting. Yes, I did:

    # firewall-cmd --add-port=10000/tcp
    # firewall-cmd --reload

    When I look at my firewall settings, I see ‘Cockpit with port 9090’, which is the default Centos Server Web portal monitoring tool.

    Thank you,


      • Hi Ravi,

        I did the following and all is good now:

        # firewalld-cmd - -add-port=10000/tcp - -permanent
        # firewalld-cmd - -reload

        Thank you for this guide, very well done and appreciated.

        Keep on the good works!:-)


  2. Instructions followed exactly the instructions, Webmin is running, firewall is off. Unfortunately it’s not working on Linux Mint 19

  3. Super easy to install in FreeBSD or FreeNAS in a jail.


    (Inside of a jail set password with “passwd”)

    pkg update
    pkg install webmin
    echo “webmin_enable=”YES”” >> /etc/rc.conf
    /usr/local/etc/rc.d/webmin start

    Once installed navigate to the IP address (hint try ifconfig to find it) and port. Login and start using it.

  4. i have installed correctly but the username and pass is not working
    i try to figure that but i cant figure /usr/libexec/webmin/ folder
    there is not libexec folder

  5. Can we use Web for patching multiple CENTOS servers in environment.

    I have install Webmin on my Systems , but i am not able to access it.It takes me to default page of Apache.Even i have added rule in iptable for the same with port 1000, 10000.
    Please contact me on my email if required.

  6. Fedora 20 uses firewalld not iptables so everything dies.
    This will fix it
    systemctl disable firewalld.service
    systemctl stop firewalld.service
    systemctl enable iptables.service
    systemctl enable ip6tables.service
    systemctl start iptables.service
    systemctl start ip6tables.service

    Of course if you are like me and like to install minimal systems you may need to run this command first.

    yum -y install iptables-services iptables-utils

  7. I installed it on Ubuntu. I was stuck at Step3.. I didnt do any restart of firewalls. Directly tried to access https://localhost:10000/ . It asked for UNAME and PWD. What’s the password I should enter here ?? I tried giving “root”, “password”, and my System Root password. Nothing worked. It just blocked my localhost IP ( ) Help me

  8. Dear sir ,

    • 1. Open up the browser and navigate to “http://www.webmin.com/jcameron-key.asc”.
      2. Copy whole output and Paste into the file “public.gpg.key”.
      3. Run import command again to import GPG key.

      # rpm --import public.gpg.key

      That’s it! GPG key installed successfully now do:

      # yum install webmin
