Webmin is a web-based management panel for any Linux machine which helps you to handle your server by a contemporary web-based interface. With Webmin, you may change settings for widespread packages on the fly, together with net servers and databases, in addition to handle customers, teams, and software program packages.

On this tutorial, you may set up and configure Webmin in your server and safe entry to the interface with a legitimate certificates utilizing Let’s Encrypt and Apache. You may then use Webmin so as to add new person accounts, and replace all packages in your server from the dashboard.


To finish this tutorial, you will have:

Step 1 — Putting in Webmin

First, we have to add the Webmin repository in order that we will simply set up and replace Webmin utilizing our package deal supervisor. We do that by including the repository to the /and so on/apt/sources.listing file.

Open the file in your editor:

  • sudo nano /and so on/apt/sources.listing

Then add this line to the underside of the file so as to add the brand new repository:

/and so on/apt/sources.listing

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

Save the file and exit the editor.

Subsequent, add the Webmin PGP key in order that your system will belief the brand new repository:

  • wget http://www.webmin.com/jcameron-key.asc
  • sudo apt-key add jcameron-key.asc

Subsequent, replace the listing of packages to incorporate the Webmin repository:

Then set up Webmin:

As soon as the set up finishes, you may be introduced with the next output:


Webmin set up full. Now you can login to https://your_server_ip:10000 as root along with your root password, or as any person who can use `sudo`.

Now, let's safe entry to Webmin by placing it behind the Apache net server and including a legitimate TLS/SSL certificates.

Step 2 — Securing Webmin with Apache and Let's Encrypt

To entry Webmin, you need to specify port 10000 and make sure the port is open in your firewall. That is inconvenient, particularly in the event you're accessing Webmin utilizing an FQDN like webmin.your_domain We're going to use an Apache digital host to proxy requests to Webmin's server working on port 10000. We'll then safe the digital host utilizing a TLS/SSL certificates from Let's Encrypt.

First, create a brand new Apache digital host file in Apache's configuration listing:

  • sudo nano /and so on/apache2/sites-available/your_domain.conf

Add the next to the file, changing the e-mail deal with and area with your personal:

/and so on/apache2/sites-available/your_domain.conf

<VirtualHost *:80>
        ServerAdmin your_email
        ServerName your_domain
        ProxyPass / http://localhost:10000/
        ProxyPassReverse / http://localhost:10000/

This configuration tells Apache to move requests to http://localhost:10000, the Webmin server. It additionally ensures that inside hyperlinks generated from Webmin will even move by Apache.

Save the file and exit the editor.

Subsequent, we have to inform Webmin to cease utilizing TLS/SSL, as Apache will present that for us going ahead.

Open the file /and so on/webmin/miniserv.conf in your editor:

  • sudo nano /and so on/webmin/miniserv.conf

Discover the next line:

/and so on/webmin/miniserv.conf


Change the 1 to a 0 It will inform Webmin to cease utilizing SSL.

Subsequent we'll add our area to the listing of allowed domains, in order that Webmin understands that once we entry the panel from our area, it is not one thing malicious, like a Cross-Website Scripting (XSS) assault.

Open the file /and so on/webmin/config in your editor:

  • sudo nano /and so on/webmin/config

Add the next line to the underside of the file, changing your_domain along with your fully-qualified area title.

/and so on/webmin/config

 . . . 

Save the file and exit the editor.

Subsequent, restart Webmin to use the configuration modifications:

  • sudo systemctl restart webmin

Then allow Apache's proxy_http module:

You may see the next output:


Contemplating dependency proxy for proxy_http: Enabling module proxy. Enabling module proxy_http. To activate the brand new configuration, you have to run: systemctl restart apache2

The output suggests you restart Apache, however first, activate the brand new Apache digital host you created:

  • sudo a2ensite your_domain

You may see the next output indicating your web site is enabled:


Enabling web site your_domain. To activate the brand new configuration, you have to run: systemctl reload apache2

Now restart Apache fully to activate the proxy_http module and the brand new digital host:

  • sudo systemctl restart apache2

Notice: Be certain that you permit incoming site visitors to your net server on port 80 and port 443 as proven within the prerequisite tutorial How To Set up Linux, Apache, MySQL, PHP (LAMP) stack on Ubuntu 18.04. You are able to do this with the command sudo ufw permit in "Apache Full".

Navigate to http://your_domain in your browser, and you will notice the Webmin login web page seem.

Warning: Do NOT log in to Webmin but, as we have not enabled SSL. In case you log in now, your credentials will likely be despatched to the server in clear textual content.

Now let's configure a certificates in order that your connection is encrypted whereas utilizing Webmin. To be able to do that, we will use Let's Encrypt.

Inform Certbot to generate a TLS/SSL certificates in your area and configure Apache to redirect site visitors to the safe web site:

  • sudo certbot --apache --email your_email -d your_domain --agree-tos --redirect --noninteractive

You may see the next output:


Saving debug log to /var/log/letsencrypt/letsencrypt.log Plugins chosen: Authenticator apache, Installer apache Acquiring a brand new certificates Performing the next challenges: http-01 problem for your_domain Enabled Apache rewrite module Ready for verification... Cleansing up challenges Created an SSL vhost at /and so on/apache2/sites-available/your_domain-le-ssl.conf Enabled Apache socache_shmcb module Enabled Apache ssl module Deploying Certificates to VirtualHost /and so on/apache2/sites-available/your_domain-le-ssl.conf Enabling out there web site: /and so on/apache2/sites-available/your_domain-le-ssl.conf Enabled Apache rewrite module Redirecting vhost in /and so on/apache2/sites-enabled/your_domain.conf to ssl vhost in /and so on/apache2/sites-available/your_domain-le-ssl.conf ------------------------------------------------------------------------------- Congratulations! You've efficiently enabled https://your_domain It is best to take a look at your configuration at: https://www.ssllabs.com/ssltest/analyze.html?d=your_domain -------------------------------------------------------------------------------

The output signifies that the certificates was put in and Apache is configured to redirect requests from http://your_domain to https://your_domain.

You've got now arrange a secured, working occasion of Webmin. Let us take a look at how you can use it.

Step 3 – Utilizing Webmin

Webmin has modules that may management all the things from the BIND DNS Server to one thing so simple as including customers to the system. Let us take a look at how you can create a brand new person, after which discover how you can replace software program packages utilizing Webmin.

To be able to log in to Webmin, navigate to http://your_domain and sign up with both the root person or a person with sudo privileges.

Managing Customers and Teams

Let's handle the customers and teams on the server.

First, click on the System tab, after which click on the Customers and Teams button. From right here you may both add a person, handle a person, or add or handle a bunch.

Let's create a brand new person known as deploy which may very well be used for internet hosting net purposes.
