How to Install Remark42 on Fedora CoreOS Latest

Remark42 is a self-hosted, open-source, and privacy-focused commenting system that allows you to easily add comments to your website or blog posts. In this tutorial, we will explain how to install Remark42 on Fedora CoreOS latest.

Prerequisites

Before starting this tutorial, you need:

• A Fedora CoreOS latest installed on your server or VM.
• An SSH client to connect to your server or VM.
• Basic knowledge of the Linux command line.

Step 1: Install Docker

Remark42 runs in a Docker container, so you need to install Docker on your Fedora CoreOS latest. To do this, follow these steps:

1. Open your terminal and log in to your server or VM as a sudo user.

2. Run the following command to install Docker:

    $ sudo rpm-ostree install docker
   

3. After successful installation of Docker, start the Docker service using the following command:

    $ sudo systemctl start docker
   

4. Verify that Docker is running by running the following command:

    $ sudo docker version
   

The output will show the Docker version and other details.

Step 2: Install Nginx

In order to use Remark42, you need to have Nginx installed on your server or VM. To install Nginx, follow these steps:

1. Run the following command to install Nginx:

    $ sudo rpm-ostree install nginx
   

2. After the installation is complete, start the Nginx service using the following command:

    $ sudo systemctl start nginx
   

3. Verify that Nginx is running by running the following command:

    $ sudo systemctl status nginx
   

Step 3: Configure Nginx

Next, you need to configure Nginx to work with Remark42. To do this, follow these steps:

1. Create a new Nginx configuration file using your preferred text editor, for example:

    $ sudo nano /etc/nginx/conf.d/remark42.conf
   

2. Add the following configuration to the file:

    server {
        listen 80;
        server_name example.com; # Replace with your domain name or server IP address
        location / {
            proxy_pass http://localhost:8080/;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
        }
    }
   

3. Save the file and exit your editor.

4. Test the Nginx configuration by running the following command:

    $ sudo nginx -t
   

5. If the output is "syntax is ok" and "test is successful", reload the Nginx service to apply the new configuration:

    $ sudo systemctl reload nginx
   

Step 4: Install and Configure Remark42

Now, you are ready to install and configure Remark42. To do this, follow these steps:

1. Pull Remark42 Docker image using the following command:

    $ sudo docker pull umputun/remark42
   

2. Create a new directory to store the Remark42 configuration files:

    $ sudo mkdir /etc/remark42
   

3. Create a new configuration file for Remark42 using your preferred text editor, for example:

    $ sudo nano /etc/remark42/remark42.yaml
   

4. Add the following configuration to the file:

    server:
        http: 0.0.0.0:8080 # Remark42 server will listen on this address and port
        editors:
            - id: "admin" # Admin user ID
              name: "Admin"
              email: "admin@example.com"
              password: "password"
   
    site:
        url: "http://example.com" # Replace with your domain name or server IP address
        title: "Remark42"
        description: "Remark42 comments"
   
    db:
        engine: "sqlite3"
        name: "remark42.db" # Remark42 database name
   
    auth:
        providers:
            - id: "builtin"
              name: "Remark42"
              type: "builtin"
   

5. Save the file and exit your editor.

6. Run the Remark42 Docker container using the following command:

    $ sudo docker run -d \
        -v /etc/remark42:/app/config \
        --restart=always \
        --name remark42 \
        -p 127.0.0.1:8080:8080 \
        umputun/remark42
   

7. Verify that Remark42 is running by checking the container logs:

    $ sudo docker logs remark42
   

8. Open your web browser and go to http://example.com (replace with your domain name or server IP address) to see the Remark42 comments section on your website or blog post.
