How To Install Git on Debian 8
Git is a version control system distributed under the terms of the GNU General Public License v.2 since its release in 2005.
Git is software used primarily for version control which allows for non-linear development of projects, even ones with large amounts of data. Every working directory in Git is a full-fledged repository with complete history and tracking independent of network access or a central server.
The advantages of using Git stem from the way the program stores data. Unlike other version control systems, it is best to think of Git's storage process as a set of snapshots of a mini filesystem, primarily on your local disk. Git maximizes efficiency and allows for powerful tools to be built on top of it.
In this tutorial we'll install and configure Git on your Debian 8 Linux server.
You'll need the following items for this tutorial:
- A Droplet running Debian 8
- A sudo user
What the Red Means
The majority of code in this tutorial can be copy and pasted as-is! The lines that you will need to customize will be red in this tutorial.
Step 1 — Installing Git with APT
Before you install Git, make sure that your package lists are updated by executing the following command:
- sudo apt-get update
Install Git with
apt-get in one command:
- sudo apt-get install git-core
This is the only command you'll need to install Git. The next part is configuring Git.
apt-get is the easiest and probably one of the most reliable ways to install Git, because APT takes care of all the software dependencies your system might have.
Now, let us take a look at how to configure Git.
Step 2 — Configuring Git
Git implements version control using two primary settings:
- A user name
- The user's email
This information will be embedded in every commit you make with Git so it can track who is making which commits.
We need to add these two settings in our Git configuration file. This can be done with the help of the
git config utility. Here's how:
Set your Git user name:
- git config --global user.name "Sammy Shark"
Set your Git email:
- git config --global user.email firstname.lastname@example.org
View all Git settings:
You can view these newly-configured settings (and all the previously existing ones, if any) using the
--list parameter in the
git config utility.
- git config --list
You should see your user settings:
Outputuser.name=Sammy Shark email@example.com
If you want to get your hands dirty with the Git configuration file, simply fire up
nano (or your favorite text editor) and edit to your heart's content:
- nano ~/.gitconfig
Here you can manually update your Git settings:
[user] name = Sammy Shark email = firstname.lastname@example.org
This is the basic configuration you need to get up and running with Git.
Adding your username and email is not mandatory, but it is recommended. Otherwise, you'll get a message like this when you use Git:
Output when Git user name and email are not set[master 0d9d21d] initial project version Committer: root Your name and email address were configured automatically based on your username and hostname. Please check that they are accurate. You can suppress this message by setting them explicitly: git config --global user.name "Your Name" git config --global user.email email@example.com After doing this, you may fix the identity used for this commit with: git commit --amend --reset-author
Congratulations on your very own Git installation.
