How to Install Centrifugo on OpenSUSE Latest

Centrifugo is an open-source real-time messaging server that lets you build scalable applications with live data streaming capabilities. Centrifugo can connect with various clients using a wide range of communication protocols, such as WebSockets, HTTP, and GRPC.

In this tutorial, we will go through the process of installing Centrifugo on OpenSUSE Latest. It requires some level of technical expertise, but the guide will take you through the necessary steps carefully. Let's get started.

Step 1: Update the system

Firstly, let's update the system to ensure all packages are up-to-date. Open the terminal app and type:

sudo zypper update 

Step 2: Install the necessary dependencies

Before installing Centrifugo, we need to install some dependencies. They are:

• git
• gcc
• g++
• make

Use the following command to install them:

sudo zypper install git gcc g++ make

Step 3: Install Go

Centrifugo is written in the Go programming language, so we need to install it. You can download the latest Go binary package from the official website (https://golang.org/dl/) or use the following command to install Go:

sudo zypper install go

Step 4: Set up the GOPATH environment variable

We need to set up the GOPATH environment variable. It specifies the directory where Go packages are installed. Open the terminal and enter:

echo "export GOPATH=\$HOME/go" >> ~/.bashrc
echo "export PATH=\$PATH:\$GOPATH/bin" >> ~/.bashrc
source ~/.bashrc

Step 5: Build Centrifugo from source

Now, let's download and install Centrifugo. To obtain the source files of Centrifugo, we need to use Git. Type the following command:

go get github.com/centrifugal/centrifugo

This will download the Centrifugo source code and install it in the appropriate directory.

Step 6: Run Centrifugo

Our installation is complete. To run Centrifugo, open a terminal and type:

cd $GOPATH/src/github.com/centrifugal/centrifugo
./centrifugo --config=config.json

This command starts the Centrifugo server with the configuration file, 'config.json'. If you want to use a different configuration file, specify it when running Centrifugo.

Conclusion

That's it! Now you have installed Centrifugo on your OpenSUSE Latest machine. You can connect to the Centrifugo server using the communication protocol of your choice and start building scalable real-time messaging applications.
