How to install Remark42 on Arch Linux

Remark42 is an open-source commenting system that can be installed easily on Arch Linux. This tutorial will guide you through the process of installing Remark42 on your Arch Linux machine.

Prerequisites

Before we start, make sure that you have the following prerequisites:

• Arch Linux machine with root access
• Docker
• Docker Compose

Step 1: Clone the Remark42 repository

To start, open a terminal and clone the Remark42 repository from its GitHub page by running the following command:

git clone https://github.com/umputun/remark42.git

Step 2: Configure Remark42

After cloning the repository, navigate to the remark42 directory and open the docker-compose.yml file in your favorite text editor:

cd remark42
sudo nano docker-compose.yml

In this file, you can configure various options such as the POSTGRES_PASSWORD and the REMARK_SECRET_KEY.

Note: Make sure to replace <your-secret-key> with your actual secret key.

version: "3"
services:
  remark42:
    image: umputun/remark42:v1.10.2
    environment:
      PG_PASSWORD: <your-db-password>
      REMARK_SECRET_KEY: <your-secret-key>
    ports:
      - "8080:8080"
    volumes:
      - ./config:/etc/remark42
    depends_on:
      - postgres
      - redis
  postgres:
    image: postgres
    environment:
      POSTGRES_PASSWORD: <your-db-password>
    volumes:
      - ./data/postgres:/var/lib/postgresql/data
  redis:
    image: redis

Save the file and exit the text editor.

Step 3: Start the Remark42 server

Now we can start the Remark42 server. Navigate to the remark42 directory and run the following command:

sudo docker-compose up -d

This will download the necessary Docker images and start the Remark42 server in the background.

Step 4: Test Remark42

After the server has started, you should be able to access Remark42 by navigating to http://localhost:8080 in your web browser. You can test the installation by creating a new account and adding a comment to a post.

Congratulations, you have successfully installed Remark42 on Arch Linux!

Step 5: Stop Remark42

If you ever need to stop the Remark42 server, navigate to the remark42 directory and run the following command:

sudo docker-compose down

This will stop the containers and clean up the Docker images.
