How to install remark42 on NetBSD

remark42 is a self-hosted, lightweight, and fast comment engine. It allows users to add comments to web pages without having to rely on third-party services.

In this tutorial, we will explain how to install remark42 on NetBSD, step by step.

Prerequisites

Before we begin, make sure that you have the following:

• A NetBSD server running with root access or sudo privileges.
• Docker and Docker Compose installed on your NetBSD server.
• A domain name pointed to your NetBSD server's IP address.

Step 1: Install Docker and Docker Compose

To install Docker and Docker Compose on your NetBSD server, run the following command:

sudo pkgin install docker docker-compose

Once the installation is complete, start the Docker service and set it to start on boot with the following command:

sudo systemctl enable docker.service
sudo systemctl start docker.service

Step 2: Create a Docker Compose file

Create a new directory for your remark42 installation and navigate to it:

mkdir remark42
cd remark42

Create a file called docker-compose.yml using your preferred text editor and add the following contents:

version: '3'

services:
  remark42:
    image: remark42/remark42:latest
    environment:
      - ADDR=0.0.0.0:8080
      - DATABASE_URL=postgres://remark42:remark42@postgres:5432/remark42?sslmode=disable
      - REMARKS_ALLOW_DELETE=false
      - REMARKS_PER_PAGE=10
      - SITE_ID=example.com
    ports:
      - "8080:8080"
    depends_on:
      - postgres

  postgres:
    image: postgres:12
    environment:
      - POSTGRES_USER=remark42
      - POSTGRES_PASSWORD=remark42
      - POSTGRES_DB=remark42
    volumes:
      - ./postgres-data:/var/lib/postgresql/data

Step 3: Run the Docker Compose file

To start the remark42 container, run the following command:

docker-compose up -d

This command will start the containers in detached mode. Wait a few seconds for the containers to start, and then check the logs using the following command:

docker-compose logs -f

You should see logs that indicate that the application is running and listening on port 8080.

Step 4: Configure your firewall

Since remark42 is running on port 8080, you will need to open that port on your server's firewall. To do that, run the following command:

sudo pfctl -e
sudo echo 'pass in proto tcp from any to any port 8080' >> /etc/pf.conf
sudo pfctl -f /etc/pf.conf
sudo pfctl -P default -f /etc/pf.conf

Step 5: Test remark42

To test whether remark42 is running correctly, navigate to http://<your-domain>:8080 in your browser. You should see the remark42 comment engine interface.

Conclusion

That's it! You have successfully installed remark42 on your NetBSD server. You can now integrate the comment engine with your website, customize it, and start collecting user feedback.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
