（1）生成ssh-key
[root@linux-node1 ~]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:Hf3O9F7sS9N04cFUr3Awb/Wec28gTpHYyRZMCzLW9q0 root@linux-node1
The key's randomart image is:

在admin账户下给dev1，dev2账户设置密码，然后使用dev1登录gitlab，做如下操作添加ssh-key：
