How do I install git and link my Linux machine to my BitBucket/GitHub account?

To start things off, connect to your remote machine:

ssh -p your_port you@your_ip_address

Now, see if you already have git installed:

which git

If your machine has git installed you'll see its path printed to your screen. Else, you'll need to install it:

sudo aptitude install git

You'll be prompted regarding incoming file size. Enter "yes". Now run:

which git

You'll see the program's path printed to your screen:

/usr/bin/git

Now we need to check and see if you have an ssh key pair on your machine or if we need to create one. To start off, we need to examine your remote machine. Run the following command:

cat ~/.ssh/id_rsa.pub

If the above command prints "No such file or directory", then you'll need to generate an ssh key pair before continuing. If the previous command printed a bunch of funny looking letters and numbers, then you already have an ssh key pair on your local machine that we can make use of!

Okay, so if your machine doesn't already have an ssh key pair on file, we can easily create one. Enter the following command:

ssh-keygen -t rsa -C "your_email@your_domain.com"

You'll be prompted with the following:

Enter file in which to save the key (/Users/you/.ssh/id_rsa):

Just press enter and "~/.ssh/id_rsa" will be used (which is what we want).

Next, you'll be prompted with the following:

Enter passphrase (empty for no passphrase):

Press enter twice to generate a key pair without a passphrase.

Now, at this point, everybody should have an "~/.ssh/id_rsa.pub" file on their remote machine. Next, log in to your BitBucket or GitHub account.

For BitBucket follow these steps:

• Step 1) Go to https://bitbucket.org/account/user/abovemarket/ssh-keys/
• Step 2) Click "Add key" as shown in the following screenshot:

• Step 3) Print your machine's id_rsa.pub file content on the command line so you can manually copy it into memory:

  cat ~/.ssh/id_rsa.pub

  After copying it, without getting a single extra character accidentally added, paste it into your BitBucket account as shown in the following screenshot:

For GitHub follow these steps:

• Step 1) Go to https://github.com/settings/ssh/
• Step 2) Click "Add SSH key" as shown in the following screenshot:

• Step 3) Print your machine's id_rsa.pub file content on the command line so you can manually copy it into memory:

  cat ~/.ssh/id_rsa.pub

  After copying it, without getting a single extra character accidentally added, paste it into your GitHub account as shown in the following screenshot:

Next, config git to use your BitBucket/GitHub email address:

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

git config --global user.email your_repo_email@your_domain.com

Now, clone your project!

For BitBucket:

git clone git@bitbucket.org:your_username/your_project.git your_domain.com

For GitHub:

git clone git@github.com:your_username/your_project.git your_domain.com

In either case, you'll be prompted about "The authenticity of host...", enter "yes".

Boom! You're done! Way to go!
