For newbies, Git is a free and open source, fast and distributed version control system (VCS), which by design is based on speed, efficient performance and data integrity to support small-scale to extensive software development projects.
Git is a software repository that allows you to keep a track of your software changes, revert to previous version and create another versions of files and directories.
Git is written in C, with a mix of Perl and a variety of shell scripts, it’s primarily intended to run on the Linux kernel and has a number of remarkable features as listed below:
- Easy to learn
- It is fast and most of its operations are carried out locally, in addition, this offers it a tremendous speed on centralized systems that need to communicate with remote servers.
- Highly efficient
- Supports data integrity checks
- Enables cheap local branching
- Offers a convenient staging area
- It also maintains multiple work-flows together with many others
In this how-to guide, we shall move through the necessary steps of installing Git on CentOS/RHEL 7/6 and Fedora 20-24 Linux distributions along with how to configure Git so that you can start participating right away..
Install Git Using Yum
We shall install Git from the system default repositories, and make sure that your system is up-to-date with the latest version of packages by running the YUM package manager update command below:
# yum update
Next, install Git by typing the following command:
# yum install git
After git successfully installed, you can issue the following command to display the version of Git installed:
# git --version
Important: Installing Git from default repositories will give you older version. If you looking to have a most recent version of Git, consider compiling from source using following instructions.
Install Git from Source
Before you begin, first you need to install required software dependencies from the default repositories, along with the utilities that needed to build a binary from source:
# yum groupinstall "Development Tools" # yum install gettext-devel openssl-devel perl-CPAN perl-devel zlib-devel
After you have installed required software dependencies, go to the official Git release page and grab the latest version and compile it from source using following series of command:
# wget https://github.com/git/git/archive/v2.10.1.tar.gz -O git.tar.gz # tar -zxf git.tar.gz # cd git-2.10.1/ # make configure # ./configure --prefix=/usr/local # make install # git --version
Set Up Git Account in Linux
In this section, we shall cover how to set up a Git account with correct user information such as name and email address to avoid any commit errors, and the
git config command is used to do that.
Important: Make sure to replace username with the actual name for the Git user to be created and used on your system.
You can start by creating a Git user with the useradd command as below, where the
-m flag used to create the user’s home directory under
-s specifies the user’s default shell.
# useradd -m -s /bin/bash username # passwd username
Now, add the new user to the wheel group to enable the account to use the
# usermod username -aG wheel
Then configure Git with the new user as follows:
# su username $ sudo git config --global user.name "Your Name" $ sudo git config --global user.email "[email protected]"
Now verify Git configuration using following command.
$ sudo git config --list
If there are no errors with the configurations, you should be able to view an output with the following details:
user.name=username user.email= [email protected]
In this simple tutorial, we have looked at how to install Git on your Linux system as well as configuring it. I believe the instructions are easy to follow, however, to get in touch with us for any questions or suggestions you can make use of the reaction section below.
