你可以连接到GitHub使用SSH

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

Adding your SSH key to the ssh-agent

Start the ssh-agent in the background.

eval "$(ssh-agent -s)"

Agent pid 59566

if you're using macOS Sierra 10.12.2 or later, you will need to modify your ~/.ssh/config file to automatically load keys into the ssh-agent and store passphrases in your keychain.

Host *

AddKeysToAgent yes

UseKeychain yes

IdentityFile ~/.ssh/id_rsa

Add your SSH private key to the ssh-agent and store your passphrase in the keychain. If you created your key with a different name, or if you are adding an existing key that has a different name, replace id_rsa in the command with the name of your private key file.

ssh-add -K ~/.ssh/id_rsa

Note: The -K option is Apple's standard version of ssh-add, which stores the passphrase in your keychain for you when you add an ssh key to the ssh-agent.

Adding a new SSH key to your GitHub account

Copy the SSH key to your clipboard.

If your SSH key file has a different name than the example code, modify the filename to match your current setup. When copying your key, don't add any newlines or whitespace.

pbcopy < ~/.ssh/id_rsa.pub# Copies the contents of the id_rsa.pub file to your clipboard

Tip: If pbcopy isn't working, you can locate the hidden .ssh folder, open the file in your favorite text editor, and copy it to your clipboard.

In the upper-right corner of any page, click your profile photo, then click Settings.

In the user settings sidebar, click SSH and GPG keys.

Click New SSH key or Add SSH key.

In the "Title" field, add a descriptive label for the new key. For example, if you're using a personal Mac, you might call this key "Personal MacBook Air".

Paste your key into the "Key" field.

Click Add SSH key.

If prompted, confirm your GitHub password.
