WebMin auf Ubuntu 18.04

To complete this tutorial, you will need:

One Ubuntu 18.04 server set up by following the Ubuntu 18.04 initial server setup guide, including a sudo non-root user and a firewall.
Apache installed by following How To Install Linux, Apache, MySQL, PHP (LAMP) stack on Ubuntu 18.04. We’ll use Apache to perform Let’s Encrypt’s domain verification and act as a proxy for Webmin. Ensure you configure access to Apache through your firewall when following this tutorial.
A Fully-Qualified Domain Name (FQDN), with a DNS A record pointing to the IP address of your server. To configure this, follow the tutorial How To Set Up a Host Name with DigitalOcean.
Certbot installed by following Step 1 of How To Secure Apache with Let’s Encrypt on Ubuntu 18.04. You’ll use Certbot to generate the TLS/SSL certificate for Webmin.

Step 1 — Installing Webmin

First, we need to add the Webmin repository so that we can easily install and update Webmin using our package manager. We do this by adding the repository to the /etc/apt/sources.list file.

Open the file in your editor:

sudo nano /etc/apt/sources.list

Then add this line to the bottom of the file to add the new repository:
/etc/apt/sources.list

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

Save the file and exit the editor.

Next, add the Webmin PGP key so that your system will trust the new repository:

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

Next, update the list of packages to include the Webmin repository:

sudo apt update

Then install Webmin:

sudo apt install webmin

Once the installation finishes, you’ll be presented with the following output:

Output
Webmin 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`.
