How to Install Centrifugo on Clear Linux

This tutorial will guide you through the installation process of Centrifugo on Clear Linux.

Overview

Centrifugo is a real-time messaging server. It can be used to power quick solutions such as chat applications, online games, and more. We will be installing Centrifugo on Clear Linux, which is a Linux distribution developed by Intel. The installation process involves the use of Docker and is relatively straightforward.

Prerequisites

Before proceeding with the tutorial, ensure that you have the following:

• A Clear Linux latest installed and running instance
• A user account with administrator privileges
• Docker installed, following instructions from the Clear Linux documentation or a previous tutorial.

Installation

1. Open the terminal on the Clear Linux instance.
2. Run the following command to download the Centrifugo container image from Docker Hub:

sudo docker pull centrifugo/centrifugo

3. Next, create a directory to store configuration files for Centrifugo:

sudo mkdir /etc/centrifugo

4. Create a configuration file using the following command. Replace [YOUR_SECRET] with a secret string to be used for the JSON Web Token (JWT) feature:

sudo bash -c 'cat > /etc/centrifugo/config.json' <<EOL 
{
  "secret": "[YOUR_SECRET]",
  "admin_password": "password",
  "admin_secret": "another_secret"
}
EOL

5. Change the ownership of the configuration file to the user account you are currently using:

sudo chown $USER /etc/centrifugo/config.json

6. Create a container for Centrifugo using the following command, which mounts the configuration files as read-only files in the container and the socket file as a writable file:

sudo docker run --net=host -v /etc/centrifugo:/centrifugo -v /run/:/run/centrifugo -p 8000:8000 centrifugo/centrifugo centrifugo -c /centrifugo/config.json

7. Once the container is up and running, you can access the Centrifugo dashboard by opening your web browser and browsing to http://localhost:8000.

Congratulations! You have successfully installed Centrifugo on Clear Linux. From here, you can test Centrifugo by integrating it into your application, as well as further configuring it to suit your needs.
