Prerequisites

To complete this tutorial, you will need:

Step 1 — Installing Webmin

Open the file in your editor:

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

OutputWebmin install complete. You can now login to 
https://your_server_ip:10000 as root with your
root password, or as any user who can use `sudo`.

Please copy down this information, as you will need it for the next step.

Note: If you installed ufw during the prerequisite step, you will need to run the command sudo ufw allow 10000 in order to allow Webmin through the firewall. For extra security, you may want to configure your firewall to only allow access to this port from certain IP ranges.

Let’s secure access to Webmin by adding a valid certificate.

Step 2 — Adding a Valid Certificate with Let’s Encrypt

Webmin is already configured Xeon Dedicated Server in Romania to use HTTPS, but it uses a self-signed, untrusted certificate. Let’s replace it with a valid certificate from Let’s Encrypt.

Navigate to https://your_domain:10000 in your web browser, replacing your_domain with the domain name you pointed at your server.

Note: When logging in for the first time, you will see an “Invalid SSL” error. This is because the server has generated a self-signed certificate. Allow the exception to continue so you can replace the self-signed certificate with one from Let’s Encrypt.

You’ll be presented with a login screen. Sign in with the non-root user you created while fulfilling the prerequisites for this tutorial.

Once you log in, the first screen you will see is the Webmin dashboard. Before you can apply a valid certificate, you have to set the server’s hostname. Look for the System hostname Dell Dedicated Server in Moldova field and click on the link to the right, as shown in the following figure:

This wil take you to the Hostname and DNS Client page. Locate the Hostname field, and enter your Fully-Qualified Domain Name into the field. Then press the Save button at the bottom of the page to apply the setting Reseller VPS Europe.

After you’ve set your hostname, click on Webmin on the left navigation bar, and then click on Webmin Configuration.

Using this screen, you’ll tell Webmin how to obtain and renew your certificate. Let’s Encrypt certificates expire after 3 months, but we can instruct Webmin to automatically attempt to renew the Let’s Encrypt certificate every month. Let’s Encrypt looks for a verification file on our server, so we’ll configure Webmin to place KVM VPS Moldova the verification file inside the folder /var/www/html, which is the folder that the Apache web server you configured in the prerequisites uses. Follow these steps to set up your certificate:

To use the new certificate, restart Webmin by clicking the back arrow in your browser, and clicking the Restart Webmin button. Wait around 30 seconds, and then reload the page KVM VPS US West and log in again. Your browser should now indicate that the certificate is valid.

Step 3 — Using Webmin

You’ve now set up a secured working instance of Webmin. Let’s look at how to use it.

Webmin has many different modules that can control everything from the BIND DNS Server to something as simple as adding users to the system. Let’s look at how to create a new user, and then explore how to update the operating system using Webmin.

Let’s explore how to manage the users and groups on your server.

First, click the System tab, and then click the Users and Groups button. Then, from here, you can either add a user, manage a user, or add or manage a group.
