How to install Webmin on RHEL 8

Administering Red Hat (RHEL) can become a complex task due to the way the system is structured, but in the same way, tools have been developed to make the administration as complete and dynamic as possible, there Webmin comes into play..

 

Webmin is a web-based interface with which it is allowed to administer Unix systems , browsers that are compatible with tables and forms are allowed for this administration, there is Java for the File Manager module, this makes it easier for Webmin to configure accounts Username, DNS, File Sharing, and more.

 

 

Webmin works with hundreds of standard modules to manage many aspects of the system and thus have full control..

 

Managed systems
Webmin can be used to manage operating systems such as:

 

  • CentOS Linux
  • Citrix Hypervisor
  • CloudLinux
  • Cloudrouter Linux
  • Cobalt Linux
  • Debian Linux
  • Fedora Linux
  • FreeBSD
  • Generic Linux
  • Gentoo Linux
  • IBM AIX
  • Linux Mint
  • Mac OS X
  • macOS Catalina
  • macOS High Sierra
  • macOS Mojave
  • macOS Sierra
  • Mandrake Linux
  • Mandrake Linux
  • Redhat Enterprise Linux
  • Redhat Linux and more

 

 

Now we are going to see how to install Webmin on RHEL 8 and thus centrally manage the system and its components.

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

image

 

Step 7

We import the GPG key with the order:
 sudo rpm --import jcameron-key.asc 

image

 

Step 8

Download the official Webmin package (the route is different today):
 sudo wget https://sourceforge.net/projects/webadmin/files/webmin/1.973/webmin-1.973-1.noarch.rpm/download 

image

 

Step 9

At the end we will see this:

Step 10

Previously the following path was used:
 wget https://prdownloads.sourceforge.net/webadmin/webmin-1.970-1.noarch.rpm 
Step 11

As of this latest version of Webmin, adjustments have been made. Now we are going to install Webmin with the following command:
 sudo rpm -Uvh webmin-1.973-1.noarch.rpm 

image

 

 

Step 12

At the end of this process we will see the following result:

Step 13

There we can see the structure that we must use to access Webmin from the browser and it is mandatory that this be done as root user. We check the Webmin port:
 sudo netstat -pnltu | grep 10000 

image

 

 

Step 14

Now we are going to grant the permissions in the Firewall for access to Webmin:
 sudo firewall-cmd --add-port = 10000 / tcp --zone = public --permanent sudo firewall-cmd –reload 

image

 

Step 15

From a browser we access Webmin using the IP or name of the device:
 https: // IP: 10000 / 
image

 

Step 16

There we must go Advanced and allow it to be redirected to the Webmin page, we will see the following:

 

image

 

 

Step 17

Enter the credentials of the root user and click Sign in to access the Webmin platform:

Step 18

On the main page we have access to details such as:

 

  • Name of the team
  • Webmin version
  • System usage time
  • Processor information
  • Current RAM memory
  • Hard disk space
  • Used operating system
  • Kernel version
  • Graphics of the status of CPU, RAM, virtual memory, etc.

 

Step 19

We can navigate through the different options for using Webmin:

Step 22

Some of the actions that we can perform with Webmin are:

 

  • Webmin configuration globally
  • Backup settings
  • Webmin user configuration
  • History of actions carried out by the user or the applications
  • View current server or computer processes
  • Change user passwords
  • View and update software packages
  • Adjust scheduled tasks
  • Access system events
  • Run data backups
  • View system users and groups
  • Manage emails
  • Open tools such as VPNs, terminal consoles, HTTP tunnel and more
  • Manage the Firewall
  • RHEL Network Interfaces General Settings
  • Manage used bandwidth

 

Each of these tasks will make it easy to manage RHEL 8 users, services, applications and processes all in one place thanks to Webmin..
