Git, GitHub

Installing & Configuring Git, Github on AWS EC2 instance along with SSH Authentication

Prerequisites:

• An active AWS account with an EC2 instance running (preferably Amazon Linux 2).

• Access credentials for your EC2 instance (SSH key pair or login details).

• An SSH client like PuTTY, MobaXterm, or the built-in terminal on your local machine.

Steps:

Connect to your EC2 instance:

1. • Open your preferred SSH client and establish a connection to your EC2 instance. Use the public IP address, username, and private key file (or password) associated with your instance.

Update your package lists:

1. • Before installing Git, update the package lists to ensure you have the latest information:

sudo yum update -y 

Install Git:

• Use the appropriate package manager command based on your EC2 instance's operating system:

  • For Amazon Linux 2:

sudo yum install git -y 

• For Ubuntu/Debian: 

sudo apt-get update -y

sudo apt-get install git -y 

• Verify the installation:

Check if Git is installed correctly by running:

git --version 

• Configure Git (optional): 

git config --global user.name "Your Name"

git config --global user.email "emailaddress@domain.com" 

• Set up ssh on a computer. 

Verify the existence of SSH key files. If the files ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub are not present, generate a new public/private key pair using the following command in a terminal or shell:

ssh-keygen -t rsa -C "emailaddress@email.com"

Obtain the contents of the id_rsa.pub file and store them in your system's clipboard for transfer.

     Paste your ssh public key into your GitHub account settings.

• Go to your GitHub Account Settings

• Select SSH and GPG keys on the left.

• Click “New SSH Key” on the right.

• Add a title and paste the public key into the text box.
