Installing Authelia on Linux Mint

Authelia is an open source authentication and authorization server that provides a single sign-on experience for your applications. This tutorial will guide you through the installation process of Authelia on a Linux Mint system.

Prerequisites

Before you begin, make sure that your system meets the following requirements:

• Linux Mint (latest version)
• sudo privileges
• Docker >= 17.12
• Docker Compose >= 1.18
• Git

Step 1: Install Docker

To install Docker on your system, run the following command:

sudo apt-get install docker docker.io

Next, start the Docker service and enable it to start at boot time:

sudo systemctl start docker
sudo systemctl enable docker

You can check if Docker is working properly by running the following command:

sudo docker run hello-world

If everything is working correctly, you should see a message saying "Hello from Docker!".

Step 2: Install Docker Compose

Docker Compose is a tool for defining and running multi-container Docker applications. To install Docker Compose, run the following command:

sudo apt-get install docker-compose

Step 3: Install Git

To install Git on your system, run the following command:

sudo apt-get install git

Step 4: Clone Authelia Repository

Clone the Authelia repository to your system by running the following command:

git clone https://github.com/authelia/authelia.git

Step 5: Customize Authelia Configuration

Before running Authelia, you need to customize the configuration file. Navigate to the "authelia" directory and copy the "config.yml.sample" file to "config.yml":

cd authelia
cp config.yml.sample config.yml

Edit the "config.yml" file to configure the authentication backend, storage backend, and other settings as per your requirements.

Step 6: Start Authelia

To start Authelia, navigate to the "authelia" directory and run the following command:

sudo docker-compose up -d

This will start Authelia in the background. You can check if it is running properly by running the following command:

sudo docker ps

Step 7: Configure Reverse Proxy

To use Authelia as a single sign-on system for your applications, you need to configure a reverse proxy that can redirect requests to Authelia. You can use popular reverse proxies like nginx or Apache for this purpose.

Configure the reverse proxy to redirect requests to Authelia by following the instructions given in the Authelia documentation.

Conclusion

In this tutorial, you learned how to install Authelia on Linux Mint and configure it to work as a single sign-on system for your applications. You can now use Authelia to provide a secure and seamless authentication experience for your users.
