How to install git on centos (tutorial)

CentOS Git Installation Tutorial

Git is a distributed version control system that developers often use to manage code. CentOs is a common Linux distribution with a wide range of applications. In this article, we will discuss how to install Git on CentOs system.

1. Installing Git

We first need to update the system packages and repositories. Update your system using the following command:

sudo yum update -y

Then, install Git using the following command:

sudo yum install git -y

This command will automatically install Git and all required dependencies and packages. After the installation is complete, we can check whether the Git installation is successful by running the following command:

git --version

If the Git version number is displayed, Git has been installed successfully.

2. Configuring Git

After installing Git, we need to configure the Git configuration. These configurations are very important for the use of Git.

First, we need to configure the username and email address used by Git. Please add your username and email address to the Git global configuration using the following command:

git config --global user.name "Your Name"
git config --global user.email "youremail@domain.com"

Please make sure to change "Your Name" and "youremail@domain.com" to your own name and email address.

Next, we need to configure Git to use the default text editor. We can set the default editor to nano by running the following command:

git config --global core.editor nano

Note that if you prefer to use a different editor, you can change "nano" to the name of your preferred editor.

After the above configuration is completed, our Git is ready.

3. Clone Git Repository

Now that we have Git installed and configured, we can use Git to clone the repository onto our local machine.

Before we clone the repository, we need to make sure we have configured an SSH connection to our Git account. We can check if the SSH key exists using the following command:

ls -al ~/.ssh

If there are no "id_rsa" and "id_rsa.pub" files in the directory, it means there is no SSH key. We can create a new SSH key using the following command:

ssh-keygen -t rsa -b 4096 -C "youremail@domain.com"

Please note that change "youremail@domain.com" to your own email address.

After generating the SSH key, we need to add the public SSH key to our Git account.

Now we can clone the Git repository using the following command:

git clone git@github.com:yourusername/yourrepositoryname.git

Please replace "yourusername" and "yourrepositoryname" with your own username and repository name. If your repository is private, authentication is required.

4. Using Git for version control

Now, we have successfully installed and configured Git, and cloned the repository. We can start versioning the repository using Git.

First, we need to move into the cloned repository directory. We then need to add all changes to the Git cache using the following command:

git add .

This will add all changes.

Next, we need to commit the changes using the following command:

git commit -m "Commit message"

Please change the "Commit message" to the message you want to use for commit.

Finally, we need to push the changes to the repository using the following command:

git push origin master

Please change "origin" to the name of your repository and "master" to the name of your repository The name of the branch to push changes to.

Summary

In this tutorial, we learned how to install, configure, and use Git on CentOS systems. Installing Git is a simple task, and following a similar process works for other Linux distributions. Configuring Git is very important because it will affect the Git experience. Using Git for version control can help developers better manage their code.
