How to Install Centrifugo on Arch Linux?

Centrifugo is a powerful real-time messaging server that provides easy-scale, reliable, and fast message broadcasting. It is an open-source system written in Go Programming Language. In this tutorial, we will guide you on how to install Centrifugo on Arch Linux.

Prerequisites

• A system running Arch Linux.
• Access to the terminal as root or a user with sudo privileges.
• Basic knowledge of the Linux command line.

Step 1 - Install Required Packages

Before starting the installation of Centrifugo, make sure your system is updated. Use the following command to update your system:

sudo pacman -Syu

After updating the system, you need to install the following required packages:

sudo pacman -S git go

Step 2 - Download and Build Centrifugo from Source

In this step, we will download the Centrifugo source code from the official GitHub repository and build it on our system. Use the following command to download and build the Centrifugo source code:

git clone https://github.com/centrifugal/centrifugo.git
cd centrifugo
go build -o centrifugo

The above command will download the Centrifugo source code into the current directory and build the Centrifugo binary file named centrifugo in the same directory.

Step 3 - Configure Centrifugo

In this step, you need to create a configuration file for Centrifugo. Create a new configuration file using the following command:

nano config.json

Add the following configuration to the config.json file:

{
  "v3_use_offset": true,
  "secret": "your_secret_key",
  "debug": true,
  "admin_password": "your_admin_password",
  "admin_secret": "your_admin_secret_key",
  "api_key": "your_api_key",
  "api_secret": "your_api_secret_key",
  "api_allow_ips": ["127.0.0.1"],
  "ssl": false,
  "websocket": true,
  "sockjs": true,
  "sockjs_endpoint": "/connection",
  "sockjs_hostname": "centrifugo.mydomain.com",
  "port": 8000,
  "insecure_admin": true,
  "namespace_limit": 10,
  "user_connection_limit": 10000,
  "node_metrics_interval_seconds": 10,
  "history_size": 100,
  "history_lifetime": 300,
  "history_recover": false,
  "presence_ping_interval": 25,
  "presence_expire_interval": 60,
  "presence_stats_period": 300,
  "private_channel_prefix": "$",
  "history_drop_inactive": true,
  "grpc": {
    "listen": "127.0.0.1:9000",
    "api_key": "your_api_key",
    "api_secret": "your_api_secret_key"
  },
  "redis": {
    "address": "127.0.0.1:6379",
    "password": "your_redis_password",
    "db": 0,
    "pool_size": 256,
    "idle_timeout_seconds": 300,
    "connect_timeout_seconds": 5,
    "read_timeout_seconds": 3,
    "write_timeout_seconds": 3 
  }
}

Make sure to replace the placeholders your_secret_key, your_admin_password, your_admin_secret_key, your_api_key, your_api_secret_key, centrifugo.mydomain.com, and your_redis_password with your desired values.

Save and close the config.json file.

Step 4 - Start Centrifugo

In this step, we will start the Centrifugo server using the following command:

./centrifugo --config=config.json

This will start the Centrifugo server on the default port 8000.

If you want to run the Centrifugo server in the background, use the following command instead:

nohup ./centrifugo --config=config.json > /dev/null 2>&1 &

Step 5 - Access the Centrifugo Web Interface

Open your web browser and navigate to http://your_server_ip:8000. You should see the Centrifugo web interface.

Congratulations! You have successfully installed Centrifugo on Arch Linux.

Conclusion

In this tutorial, we have shown you how to install Centrifugo on Arch Linux. You can now use Centrifugo to power your real-time messaging applications.
