Installing Nebula on Elementary OS

In this tutorial, we will guide you through the process of installing Nebula on Elementary OS. Nebula is a networking platform designed to connect computers securely and easily.

Prerequisites

Before you start installing Nebula, make sure that your system meets the following prerequisites:

Elementary OS version: Latest
Git installed on your system
Basic knowledge of Linux commands

Step 1: Installing Nebula

Open the terminal by pressing Ctrl+Alt+T on your keyboard.
Update your system packages by running the following command:
```
sudo apt update && sudo apt -y upgrade
```
Install the required dependencies by running the following command:
```
sudo apt -y install build-essential
```
Install Go programming language by using the snap package manager:
```
sudo snap install go --classic
```
Once Go is installed, you can download the Nebula repository by typing:
```
go get github.com/slackhq/nebula
```
This command will download the Nebula repository to your Go folder located at /home/your-user/go/src/github.com/slackhq/nebula.
Change the directory to Nebula by running the following command:
```
cd /home/your-user/go/src/github.com/slackhq/nebula
```
Install the dependencies required by Nebula by executing the following command:
```
make deps
make
sudo make install
```
This command will install Nebula on your system.
Validate the installation by running the following command:
```
nebula --version
```
This should output the version number of the Nebula that you have installed.

Step 2: Configuring Nebula

To configure Nebula, you need to create a configuration file. You can use the sample configuration file provided by Nebula as a template. You can copy the sample file to your home directory with the following command:
```
cp /home/your-user/go/src/github.com/slackhq/nebula/examples/config.yml /home/your-user/
```
This command will create a config.yml file in your home directory.
Edit the config.yml file to suit your needs. You can use a text editor of your choice such as Nano:
```
nano /home/your-user/config.yml
```
This will open the configuration file for editing. You can modify the IP addresses, subnets, and other parameters as needed.
Save the configuration file by pressing Ctrl+X, then Y, and finally Enter.

Step 3: Running Nebula

To run Nebula, you need to execute the following command:
```
nebula -config /home/your-user/config.yml
```
This will start the Nebula service with the specified configuration file.
You can also add Nebula as a service to run at boot time by using the following command:
```
sudo systemctl enable nebula
```
This command will enable Nebula to start automatically at boot time.
