1. Check the existence of the SSH Key.
If the id_rsa.pub or id_dsa.pub file exists, skip this step.

$ cd ~/.ssh # 查看用户根目录下.ssh文件夹
$ ls

When creating an ssh key, you will be prompted with a custom name and a password for pushing (not the git login password). It is generally recommended to skip it and press Enter three times. If the creation is successful, a small frame with a pattern will appear.

$ ssh-keygen -t rsa -C "[email protected]"

Copy the public key content to gitLab and add it.

$ cat ~/.ssh/id_rsa.pub
