Tutorial on setting up a git development environment

Foreword:

Git is a distributed version control system. Because of its efficiency, stability, and power, it has become one of the indispensable tools for developers. When using Git for development, you need to configure and build the corresponding development environment. The following is a detailed introduction to setting up the Git development environment.

1. Install Git

There are many ways to install Git. The following are two commonly used methods.

1. Download the Git installation package corresponding to the operating system from the official website and install it.

The official website to install Git: https://git-scm.com/

2. In Linux systems, you can install Git through the command line. The specific operations are as follows.

In Ubuntu, you can install Git through the following command:

sudo apt-get update
sudo apt-get install git

In CentOS, you can install Git through the following command:

yum install git

2. Git configuration

After installing Git, you need to perform basic configuration to better adapt it to your development environment.

1. git config command

Git configurations are in the ~/.gitconfig file and can be configured using the git config command.

View the current Git configuration information:

git config --list

Configure Git user name and email:

git config --global user.name "your_name"
git config --global user.email "your_email@example.com"

Configure Git’s default text editor:

git config --global core.editor vim

Some others Commonly used configurations:

git config --global color.ui true
git config --global alias.st status
git config --global alias.ci commit
git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.df diff

2. SSH configuration

When using Git for development, an SSH connection is required, so SSH configuration is required.

Generate SSH key:

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

Add the public key to GitHub:

Copy the public key content and paste it into GitHub -> settings -> SSH and GPG New SSH key in keys.

3. Create a Git warehouse

There are two ways to create a Git warehouse.

1. Create a Git repository on the GitHub website.

Creating a Git repository on the GitHub website is very simple, just click new repository on the GitHub homepage.

2. Create a Git repository locally.

Create a new folder locally and initialize it as a Git repository:

mkdir my_project
cd my_project
git init

4. Basic Git operations

1. Submit code to the Git repository

Use the following command to submit the code to the Git repository:

git add .
git commit -m "description"

2. Upload the code to GitHub

Use the following command to upload the code to GitHub ：

Add remote warehouse:

git remote add origin git@github.com:your_name/your_project.git

Push code:

git push -u origin master

3. Branch management

Use the following command to create a branch:

git branch feature

Use the following command to switch branches:

git checkout feature

Use the following command to merge branches:

git merge feature

4. Summary

This article details the process of building a Git development environment. , including the installation and configuration of Git, SSH configuration, creation of Git warehouse and basic operations of Git. I hope it will be helpful to the majority of developers. Using Git for development can improve development efficiency and the reliability of code management, so it is recommended that developers actively try to use Git.
