How to Install Huginn on OpenBSD

Huginn is a self-hosted automation system that can perform various tasks like monitoring websites, sending notifications, and fetching data. In this tutorial, you will learn how to install Huginn on OpenBSD.

Prerequisites

Before installing Huginn on OpenBSD, make sure you have the following prerequisites:

A server running OpenBSD
OpenBSD user with sudo privileges

Step 1: Install Required Packages

OpenBSD uses the package manager called OpenBSD packages. You can install the required packages for Huginn by running the following command:

$ doas pkg_add ruby git

Step 2: Install RVM

RVM stands for Ruby Version Manager and is used to manage multiple Ruby environments on a single system. You can install RVM by running the following command:

$ gpg --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
$ \curl -sSL https://get.rvm.io | bash -s stable
$ source ~/.rvm/scripts/rvm

Once RVM is installed, you can verify the installation by running the following command:

$ rvm -v

Step 3: Install Ruby

Huginn requires Ruby version 2.6 or higher, which can be installed using RVM. Run the following command to install Ruby:

$ rvm install 2.6

You can verify the installation by running the following command:

$ ruby -v

Step 4: Clone Huginn

Clone the Huginn repository from GitHub by running the following command:

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

Step 5: Install Dependencies

Huginn has several dependencies that need to be installed before running it. Run the following command:

$ bundle install --deployment --without development test

This command installs all the required gems into the vendor/bundle directory.

Step 6: Setup Database

Huginn uses PostgreSQL as its database backend. Install the PostgreSQL server and client by running the following command:

$ doas pkg_add postgresql-server postgresql-client

After the installation, initialize the PostgreSQL server:

$ doas -u _postgresql /usr/local/bin/initdb -D /var/postgresql/data
$ doas rcctl start postgresql

Create a PostgreSQL user and a database for Huginn:

$ doas su - _postgresql
$ createdb -E utf8 -O huginn huginn_db

Finally, update the config/database.yml file in the Huginn directory with the PostgreSQL details.

Step 7: Run Huginn

With all the dependencies installed and the database setup, Huginn can now be run using the following command:

$ bundle exec rails s -p 3000

This command starts Huginn on port 3000. You can access the Huginn web interface by visiting http://<server-ip>:3000/.

Conclusion

In this tutorial, you learned how to install Huginn on OpenBSD. You can now use Huginn to automate various tasks on your OpenBSD server.
