How to Install Huginn on Arch Linux

Huginn is a powerful open-source tool that allows you to create automated agents that can perform tasks such as monitoring websites, extracting data, and sending email alerts. In this tutorial, we will explain how to install Huginn on Arch Linux.

Prerequisites

Before we start installing Huginn, ensure that your Arch Linux system is up to date by running the following command:

sudo pacman -Syu

Step 1: Install Required Dependencies

The first step is to install the dependencies required by Huginn. For this, we must install the following packages:

sudo pacman -S ruby mariadb redis imagemagick tesseract perl-libwww

Once the installation finishes, allow the database service to start at boot time:

sudo systemctl enable mariadb.service

Step 2: Install the RVM (Ruby Version Manager)

Huginn requires Ruby 2.6. You can install it using RVM, which allows you to manage multiple Ruby versions easily. To install RVM, run the command below:

curl -sSL https://get.rvm.io | bash -s stable

Once the installation is complete, use the following command to reload the environment:

source /home/your-username/.rvm/scripts/rvm

Note: Replace "your-username" with your actual username.

Step 3: Install and Configure Huginn

Visit the Huginn GitHub repository and clone the repository onto your system:

git clone https://github.com/huginn/huginn.git && cd ./huginn

Next, install Huginn by running the following command:

rvm install "ruby-2.6.3"
rvm use 2.6.3@huginn --create
bundle install

Then configure the database with the following command:

cp .env.example .env

Update the following fields in the .env file with your own settings:

DATABASE_URL=mysql2://yourusername:yourpassword@localhost/huginn?encoding=utf8mb4&timezone=UTC&read_timeout=5&write_timeout=5&connect_timeout=1
RAILS_ENV=production
RAILS_SERVE_STATIC_FILES=true

Now, create the database and set its permissions by running the following commands:

mysql -u root -p
create database huginn;
grant all privileges on huginn.* to yourusername identified by 'yourpassword';
quit;

Next, run the migrations and seed the database:

rake db:migrate
rake db:seed

Finally, start Huginn:

./bin/rails server -d -b 0.0.0.0

You can access the Huginn web interface by visiting the IP address or hostname of your Arch Linux system followed by port 3000 (http://your-server-ip-or-domain:3000). You login details are:
