How to install Discourse on NetBSD

Discourse is a popular open-source software for building internet forums, blogs, and mailing lists. It is written in Ruby on Rails and requires a stack of software components to work.

This tutorial will guide you through the process of installing Discourse on NetBSD.

Prerequisites

  • A VPS or dedicated server running NetBSD
  • Root access to the server
  • At least 2GB of RAM
  • At least 2 CPU cores

Step 1: Install Docker

Discourse requires Docker to be installed on the server. Docker is a containerization platform that lets you run applications in isolated environments.

To install Docker on NetBSD, run the following commands:

# Install dependencies
pkgin update
pkgin install curl ca-certificates

# Install Docker
curl -fsSL https://get.docker.com -o get-docker.sh
sh get-docker.sh

Step 2: Install Docker Compose

Docker Compose is a tool that lets you define and run multi-container Docker applications. It is required by Discourse.

To install Docker Compose on NetBSD, run the following commands:

# Install dependencies
pkgin update
pkgin install py37-pip

# Install Docker Compose
pip install docker-compose

Step 3: Clone the Discourse repository

Next, you need to clone the Discourse repository from Github.

cd /opt
git clone https://github.com/discourse/discourse_docker.git discourse
cd discourse

Step 4: Configure Discourse

Copy the samples/env file to .env, which contains the configuration settings you need to change.

cp samples/env .env

Edit the .env file and set the following variables:

  • DISCOURSE_HOSTNAME: Set the domain name or IP address of your Discourse website.
  • DISCOURSE_SMTP_ADDRESS: Set the SMTP server address to send emails.
  • DISCOURSE_SMTP_PORT: Set the port number for the SMTP server.
  • DISCOURSE_SMTP_USER_NAME: Set the username for the SMTP server.
  • DISCOURSE_SMTP_PASSWORD: Set the password for the SMTP server.

Save and close the .env file.

Step 5: Create Discourse Containers

Discourse consists of several containers that need to be created using Docker Compose.

docker-compose up -d

This command creates the following containers:

  • app: The main Discourse application.
  • db: The PostgreSQL database.
  • redis: The Redis data store.
  • nginx: The web server.

Step 6: Check Discourse Installation

Once the containers are running, you can check the installation by visiting your Discourse website in a web browser. The URL will be http://your-discourse-url.

If everything is working fine, you will see the Discourse installation wizard.

Conclusion

In this tutorial, you learned how to install Discourse on NetBSD. Discourse is a powerful forum software that requires some special installation steps, but with this guide, you should have everything you need to get it up and running.
