How to Install Centrifugo on macOS

Centrifugo is a real-time messaging server which works over HTTP and WebSocket protocols. It helps to build scalable, efficient and reliable real-time applications.

Here's a step-by-step tutorial for installing Centrifugo on macOS:

Prerequisites

Before installing Centrifugo, make sure you have the following installed on your system:

• Go language
• Redis

To check if Go is installed, run the following command in the terminal:

go version

Install Centrifugo

1. Open the terminal on your macOS system.

2. Type the following command to install the Centrifugo package:

go get github.com/centrifugal/centrifugo

This will clone the Centrifugo repository to your system and install it.

3. Once the installation is complete, navigate to the centrifugo directory:

cd $GOPATH/src/github.com/centrifugal/centrifugo

4. Next, build the binary file of Centrifugo by running the following command:

make build

5. After the build process completes, you should see a centrifugo binary file in the /bin directory:

$ ls bin/
centrifugo

6. Copy this binary file to your /usr/local/bin directory, which will make it globally accessible:

sudo cp bin/centrifugo /usr/local/bin/

7. Verify the installation by running:

centrifugo version

The version number of Centrifugo should be displayed.

Configuration

To configure Centrifugo, create a configuration file called config.json at the root of your project directory:

{
  "redis_address": "localhost:6379",
  "secret": "mysecretkey",
  "publish": {
    "http": {
      "enabled": true,
      "port": 8000
    },
    "websocket": {
      "enabled": true,
      "port": 8001
    }
  }
}

This configuration assumes you're running Redis locally on the default port with no password. Adjust this as per your Redis configuration.

Running Centrifugo

Finally, to run Centrifugo, run the following command:

centrifugo --config=config.json

Centrifugo will start running as a real-time messaging server with HTTP and WebSocket protocols enabled.

Congratulations! You've successfully installed and configured Centrifugo on your macOS system.
