./setup.sh

Authelia

For security reasons and convenience, the login portal Authelia will be installed.

Redis-Server

Install Redis with the following command:

apt install redis-server

After installing Redis, start redis service and enable it to start after system reboot with the following command:

systemctl start redis-server
systemctl enable redis-server

Verify the status of the redis server:

systemctl status redis-server

By default, Redis listening on the localhost on port 6379. You can check it with the following command:

ps -ef | grep redis

Open Redis CLI and set passphrase for redis server, which is needed in the authelia configuration file

redis-cli
CONFIG SET requirepass "yourpassword"

Test if passphrase is working correctly

AUTH yourpassword

Installation

Download, unzip and rename latest Authelia archive:

cd /usr/bin
wget https://github.com/authelia/authelia/releases/download/v4.26.2/authelia-linux-amd64.tar.gz
tar -xzf authelia-linux-amd64.tar.gz
rm authelia-linux-amd64.tar.gz
mv ./authelia-linux-amd64 ./authelia

After unzipping, the service file authelia.service has to be moved:

mv authelia.service /etc/systemd/system/

Create folder for the authelia configuration file:

mkdir /etc/authelia
cd /etc/authelia

Move the unzipped file config.template.yml to the created folder:

mv config.template.yml /etc/authelia/

users_database.yml

Create users_database.yml in the folder /etc/authelia/:

nano users_database.yml

An user entry looks like this:

john:
    displayname: "John Doe"
    password: "$argon2id$v=19$m=65536,t=3,p=2$BpLnfgDsc2WD8F2q$o/vzA4myCqZZ36bUGsDY//8mKUYNZZaR0t4MFFSs+iM"
    email: john.doe@authelia.com
    groups:
      - admins
      - dev

The password is encrypted so we have to get the hash value with:

authelia hash-password 'yourpassword'

configuration.yml

Create configuration.yml at the same folder:

nano configuration.yml

Start authelia and check status:

systemctl start authelia
systemctl status authelia
