I am giving just a small introduction to people who dont know about webmin.

Most of the developers are the fan of the Unix Operating system. We all love it for it’s flexibility and being an open source.

In this tutorial, let us see how to install webmin on ubuntu 16.04 (One of favorite and most widely used operating system).

Also, let us see how to secure the connection to the webmin. Let us dive into requirements.

Requirements

  • Configure your ubuntu root server according to this initial server setup guide. You will require a sudo non root user. It is recommend by us and we have shown how to create one in the above linked tutorial.

Install Webmin Ubuntu 16.04

Ubuntu has many software in their repository also they support adding additional software to their repository. To add the webmin to the Ubuntu repository, just do the following.

Open the source.list file using nano editor.

The file will open and you have to scroll to the bottom of the file and this below line at the end.

After that, save and exit the file.

Then, you have to get the PGP key to for further process. PGP stands for Pretty Good Privacy. It helps to encrypt the file so fast. Use the below command to get the PGP key

Then add the key using the following command.

Once you have done with the above process, now its time to update the package index.

Now, install the webmin using the following command.

You should get the following output once you done with the process.

Here is the another thing you have to do.

You should allow the port 10000 in ufw in order for the webmin to work.

Install SSL for Webmin using Let’s Encrypt

Here our another step is to install the Valid SSL certificate using the webmin.

Webmin, by default has the Self signed ssl certificate.

But, the google will show it as unsafe since the certificate is not from the trusted source.

Inside the webmin, you have the option to generate the Let’s encrypt file. You have to just set the location for the certificate to be stored.

Now:

To login to the webmin panel, visit http://your_domain_name:10000. Remember, 10000 is the port used by Webmin.

The login dashboard will open and you can login using the sudo non root user account which you have created while following our above mentioned initial server setup tutorial.

Once you login to the webmin, your first step is to change the hostname to  create valid SSL certificate. You can see the System Hostname field.

There, you can edit and enter your domain name.

Then go to webmin->webmin-webmin configuration->SSL Encryption->Let’s Encrypt.

We will configure the Let’s encrypt here. The validity of let’s encrypt certificate is 3 months.

We can instruct webmin to automatically renew the certificate every two months. Or else, you can make it thorugh cron job. But, using webmin for auto renewal is simple task.

The let’s encrypt looks for verification file and we will place the file in the web directory /var/www/html.

First, enter your domin name to generate certificate and then enter the /var/www/html file.

After that, you can choose between manual renewal and automatic renewal.

Then, request the certificate. it will be generated within few minutes and you can see the confirmation.

Restart the webmin button to make use of the new certificate.
