How to Install Nebula from GitHub on Linux Mint

Nebula is one of the open-source projects developed by Slack Technologies, Inc. It is a scalable overlay networking tool that enables secure communication between virtual or physical nodes. In this tutorial, we will guide you step-by-step to install the Nebula software from GitHub on Linux Mint.

Prerequisites

Before installing Nebula, ensure that you have the following prerequisites:

• A Linux Mint OS installed on your machine
• A terminal emulator (Terminal or any other emulator)
• Git software installed on your machine (sudo apt install git)

Step 1: Install Go

Nebula is developed in the Go programming language. You need to install Go on your Linux Mint machine.

1. Open the terminal emulator on your Linux Mint machine.
2. Run the following command to download the latest version of Go from the official Go website:

wget https://golang.org/dl/go1.17.2.linux-amd64.tar.gz

3. Extract the downloaded package by running the following command:

sudo tar -xvf go1.17.2.linux-amd64.tar.gz -C /usr/local

4. Add the Go binary path to the PATH variable by running the following command:

echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.bashrc

5. Reload the bashrc file:

source ~/.bashrc

6. Verify the Go installation by running the following command:

go version

If everything is installed correctly, you'll see output similar to this:

go version go1.17.2 linux/amd64

Step 2: Download Nebula Source Code

To download Nebula Source code from GitHub, follow these steps:

1. Open a terminal window on your Linux Mint machine.
2. Run the following command to download the Nebula Source code:

git clone https://github.com/slackhq/nebula.git

The Nebula source code is now available under the nebula directory.

Step 3: Install Nebula

After you have downloaded the source code, you need to install the software by following these steps:

1. Go to the nebula directory by running the following command:

cd nebula

2. Compile and build Nebula by running the following commands:

make build

This will download all the required dependencies and build the Nebula binary.

3. Install Nebula on your machine by running the following command:

sudo make install

Nebula is now installed on your Linux Mint machine. You can verify the installation by running the following command:

nebula --version

If everything is installed correctly, you'll see the version number displayed on the terminal.

Step 4: Configure Nebula

To configure Nebula, create a configuration file named config.yml in the nebula directory.

sudo nano /etc/nebula/config.yml

You can find an example configuration file in the Nebula source code, located in the examples/ directory.

Once you have created the configuration file, save and close it.

Conclusion

Nebula helps you to deploy and manage secure overlay networks for your virtual or physical nodes. In this tutorial, we have guided you step-by-step to install Nebula from GitHub on Linux Mint. You can now use Nebula to create overlay networks for your applications.
