How to build github locally

With the continuous development of the open source community, GitHub has become a very important code hosting platform. It not only provides code hosting functions, but also provides many simple and easy-to-use functions, such as code review, issue tracking, and Pull Request and so on. Although most developers can use GitHub for code hosting, some students may encounter problems such as inconvenient access to the Internet, so they need to build GitHub locally to ensure the smooth progress of the code.

1. Install Git

Before building GitHub locally, you need to install Git first. Git is a distributed version control system. No development team can perform version control without Git, so installing Git is the first step to build GitHub.

When installing Git under Windows, you can download the Git installation program from the Git official website, and follow the default settings during installation to complete the installation. Installing Git through the terminal under macOS or Linux is very simple. You only need to run the following command in the terminal:

sudo apt update
sudo apt install git

2. Generate SSH key

In order to ensure communication between the local and GitHub For security, you need to generate an SSH key locally for verification when communicating with GitHub. Here's how to generate an SSH key for GitHub:

1. Enter ssh-keygen -t ed25519 -C "your_email@example.com" in the command line terminal. Among them, you need to replace your_email@example.com with your email address.
2. Follow the prompts and press the Enter key until the random number generation is completed.

After generation, you can find id_ed25519 and id_ed25519.pub in the .ssh directory under the local user root directory. file, where id_ed25519 is the private key file and id_ed25519.pub is the public key file.

3. Add the public key on GitHub

After generating the SSH key locally, you need to copy the public key to GitHub and add it to your account in order to code on GitHub operate. The specific steps are as follows:

1. After opening the GitHub homepage, click the avatar in the upper right corner to enter the "Settings" interface.
2. In the "Settings" interface, select the "SSH and GPG keys" option, and then click the "New SSH key" button.
3. In the "Key" text box, paste all the contents of the id_ed25519.pub file generated previously.
4. Give the public key a name (fill it in casually), and then click the "Add SSH key" button.

4. Build GitHub locally

After completing the first three steps, you can start building GitHub locally.

1. Enter git clone git@github.com:username/repo.git in the command line terminal. Among them, username is your account name on GitHub, and repo is the name of the warehouse you want to clone.
2. Locally, enter the project directory you just cloned (that is, the repo directory).
3. After modifying the code locally, enter the following command on the command line:

git add .
git commit -m "your message"
git push

Among them, "your message" is the description information of your code submission.

OK, now, you have successfully built GitHub locally. Let’s start enjoying the open source journey without network and fear!
