How to manage Git code by creating SSH key

1. Check if your computer already has an SSH Key?

Run the following command to view:

$ cd ~/.ssh
$ ls

If id_rsa.pubthe or id_dsa.pub file exists, it means that your computer already has it SSH Keyand can be used directly. If not, it needs to be created.

4. Code hosting

SSH keyThe configuration is successful, then the next step is definitely the need to remotely host the local code. First of all, we first associate the local project.

git remote add origin git@github.com:xxxx/项目名称.git

code push
