Ubuntu Server 连接 Git 和 GitHub Repo

1. 安装Helix编辑器 #

使用root用户登录到服务器，安装Helix编辑器。

sudo add-apt-repository ppa:maveonair/helix-editor
sudo apt update
sudo apt install helix

2. 切换到项目ssh用户 #

sudo su heybran-invoice-builder

3. Generate a New SSH Key (Deploy Key) #

Generate a new SSH key specifically for this repository. Run:

ssh-keygen -t ed25519 -C "[email protected]" -f ~/.ssh/invoice-builder-repo-key

• The -f flag specifies the file name to avoid overwriting existing SSH keys.
• Leave the passphrase blank (recommended for deploy keys).

This command creates two files: invoice-builder-repo-key (private key) and invoice-builder-repo-key.pub (public key) in ~/.ssh/.

Generating public/private ed25519 key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/heybran-invoice-builder/.ssh/invoice-builder-repo-key
Your public key has been saved in /home/heybran-invoice-builder/.ssh/invoice-builder-repo-key.pub

4. Add the Key to the SSH Agent #

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/invoice-builder-repo-key

5. Add the Deploy Key to the GitHub Repository #

• Copy the public key cat /home/heybran-invoice-builder/.ssh/invoice-builder-repo-key.pub
• Go to your GitHub repository in your web browser.
• Navigate to Settings > Deploy keys.
• Click Add deploy key.
• Paste the public key and give it a descriptive name (e.g., “Ubuntu Server Deploy Key”).
• Check the Allow write access box if you need push access, and then click Add key.

6. Configure Git to Use the Deploy Key for This Repository #

Open or create the ~/.ssh/config file to specify which key to use for this repository, if this file doesn’t exit already.

cd /home/heybran-invoice-builder/.ssh
hx config

Add the following configuration to ~/.ssh/config:

Host adonisjs-invoice-app
    HostName github.com
    User git
    IdentityFile ~/.ssh/invoice-builder-repo

In your local Git repository for AdonisJS-Invoice-App, set the remote to use adonisjs-invoice-app as the host:

git remote set-url origin adonisjs-invoice-app:heybran/AdonisJS-Invoice-App.git

Run this command to test if Git is connecting through the specified SSH config:

ssh -T adonisjs-invoice-app

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
