This guide will walk you through the basics and explain a little bit about how everything works along the way.</span> - -##<span>First:</span> Download and Install Git - -At the heart of GitHub is an open source version control system (VCS) called Git*. Created by the same dudes that created Linux, Git is responsible for everything GitHub related that happens locally on your computer. - -_*If you don’t already know what Git is, <a href="http://progit.org/book/ch1-3.html" target="_blank">take a crash course.</a>_ - -1. <span class="step-title">Download and install the latest version of Git with Synaptic.</span> - - We suggest you install git-core, git-gui, and git-doc. - - <img src="/images/bootcamp/bootcamp_1_linux_install_1.jpg" width="558" height="426" alt="Open Synaptic" /> - <img src="/images/bootcamp/bootcamp_1_linux_install_2.jpg" width="558" height="480" alt="Mark git-core, git-gui, and git-doc for installation" /> - <img src="/images/bootcamp/bootcamp_1_linux_install_3.jpg" width="558" height="480" alt="git-core, git-gui, and git-doc are selected" /> - - When you’ve selected git-core, git-gui, and git-doc, hit “Apply” to install them. - - <img src="/images/bootcamp/bootcamp_1_linux_install_4.jpg" width="558" height="173" alt="Click Apply" /> - - If you don’t have a package manager like Synaptic, or you’d rather install the necessary git components from the command line, you can alternatively run the script below: - - <pre class="terminal bootcamp"> - <span class="codeline">$ sudo apt-get install git-core git-gui git-doc<span>Installs git-core, git-gui, and git-doc on your system</span></span> - </pre> - - __*Note*__ Don’t worry that you don’t see an icon when it’s done. It’s not that kind of application. - -##<span>Next:</span> Set Up SSH Keys - -We use SSH keys to establish a secure connection between your computer and GitHub. Setting them up is fairly easy, but does involve a number of steps. - -To make sure you generate a brand new key, you need to check if one already exists. First, you need to open an app called Terminal. - -<img src="/images/bootcamp/bootcamp_1_linux_terminal.jpg" width="558" height="328" alt="Open the terminal" /> - -<div class="more-info"> - <h4 class="compressed">Need a quick lesson about Terminal?</h4> - <div class="more-content"> - <p>Code blocks like those on this page are part of a scripting language called Bash. To use Bash scripts, we need to use an application that comes with Linux called Terminal.</p> - - <h4>Input</h4> - <pre class="terminal bootcamp"> - <span class="codeline">$ echo 'This is input text'<span>This tooltip tells you what's going on.</span></span> - </pre> - - <p>A line that begins with the dollar sign ($) indicates a line of Bash script you need to type. To enter it, type the text that follows the $, hitting the return key at the end of each line. You can hover your mouse over each line for an explanation of what the script is doing.</p> - - <h4>Output</h4> - <pre class="terminal bootcamp"> - <span class="bash-output">This is output text.</span> - </pre> - - <p>A line that does not begin with a $ is output text that is intended to give you information or tell you what to do next. We’ve colored output text green in these bootcamp tutorials.</p> - - <h4>User Specific Input</h4> - <pre class="terminal bootcamp"> - <span class="codeline">$ echo '<em>username</em>'<span>Outputs the text in the quotation marks.</span></span> - </pre> - - <p>Areas of yellow text represent your own personal info, repos, etc. If it is part of an input ($) line, you should replace your it with your own info when you type it. If it is part of output text, it is just for your reference. It will automatically show your own info in Terminal.</p> - - <p><strong>Good to know</strong>: There will be times when you type code, hit return, and all you are given is another prompt. Some actions that you execute in Terminal don’t have any output. Don’t worry, if there is ever a problem with your code, Terminal will let you know.</p> - - <p><strong>Good to know</strong>: For security reasons, Terminal will not display what you type when entering passwords. Just type your password and hit the return key.</p> - </div> -</div> - -1. <span class="step-title">Check for SSH keys. <span>Have an existing kepair? You can skip to Step 4.</span></span> - - First, we need to check for existing ssh keys on your computer: - - <pre class="terminal bootcamp"> - <span class="codeline">$ cd ~/.ssh<span>Checks to see if there is a directory named ".ssh" in your user directory</span></span> - </pre> - - If it says “No such file or directory“ skip to __step 3__. Otherwise continue to __step 2__. - -2. <span class="step-title">Backup and remove existing SSH keys.</span> - - Since there is already an SSH directory you’ll want to back the old one up and remove it: - - <pre class="terminal bootcamp"> - <span class="codeline">$ ls<span>Lists all the subdirectories in the current directory</span></span> - <span class="bash-output">config id_rsa id_rsa.pub known_hosts</span> - <span class="codeline">$ mkdir key_backup<span>makes a subdirectory called "key_backup" in the current directory</span></span> - <span class="codeline">$ cp id_rsa* key_backup<span>Copies the contents of the id_rsa directory into key_backup directory</span></span> - <span class="codeline">$ rm id_rsa*<span>Deletes the contents of the id_rsa directory</span></span> - </pre> - -3. <span class="step-title">Generate a new SSH key.</span> - - To generate a new SSH key, enter the code below. We want the default settings so when asked to enter a file in which to save the key, just press enter. - - <pre class="terminal bootcamp"> - <span class="codeline">$ ssh-keygen -t rsa -C "<em>user_name@username.com</em>"<span>Creates a new ssh key using the provided email</span></span> - <span class="bash-output">Generating public/private rsa key pair.</span> - <span class="bash-output">Enter file in which to save the key (/home/<em>your_user_directory</em>/.ssh/id_rsa):</span> - </pre> - - Now you need to enter a passphrase. - - <div class="more-info"> - <h4 class="compressed">Why do passphrases matter?</h4> - <div class="more-content"> - <p>Passwords aren’t very secure, you already know this. If you use one that’s easy to remember, it’s easier to guess or brute-force (try many options until one works). If you use one that’s random it’s hard to remember, and thus you’re more inclined to write the password down. Both of these are Very Bad Things™. This is why you’re using ssh keys.</p> - - <p>But using a key without a passphrase is basically the same as writing down that random password in a file on your computer. Anyone who gains access to your drive has gained access to every system you use that key with. This is also a Very Bad Thing™. The solution is obvious: add a passphrase.</p> - - <p><em>But I don’t want to enter a long passphrase every time I use the key!</em></p> - - <p>Neither do we! Thankfully, there’s a nifty little tool called <code>ssh-agent</code> that can save your passphrase securely so you don’t have to re-enter it. Most linux installations will automatically start <code>ssh-agent</code> for you when you log in.</p> - - <p>For more information about SSH key passphrases, check out our <a href="/working-with-key-passphrases">help guide</a>.</p> - </div> - </div> - - <pre class="terminal bootcamp"> - <span class="bash-output">Enter passphrase (empty for no passphrase):</span> - <span class="bash-output">Enter same passphrase again:</span> - </pre> - - Which should give you something like this: - - <pre class="terminal bootcamp"> - <span class="bash-output">Your identification has been saved in /home/<em>your_user_directory</em>/.ssh/id_rsa.</span> - <span class="bash-output">Your public key has been saved in /home/<em>your_user_directory</em>/.ssh/id_rsa.pub.</span> - <span class="bash-output">The key fingerprint is:</span> - <span class="bash-output">01:0f:f4:3b:ca:85:d6:17:a1:7d:f0:68:9d:f0:a2:db <em>user_name@username.com</em></span> - <span class="bash-output">The key's randomart image is:</span> - <span class="bash-output">+--[ RSA 2048]----+</span> - <span class="bash-output">| .+ + |</span> - <span class="bash-output">| = o O . |</span> - <span class="bash-output">| = * * |</span> - <span class="bash-output">| o = + |</span> - <span class="bash-output">| o S . |</span> - <span class="bash-output">| o o = |</span> - <span class="bash-output">| o .
