GitLab项目仓库及SSH密钥配置与连接

新建仓库

在没有配置SSH密钥对之前，无法使用基于SSH的代码推拉操作。

You won’t be able to pull or push project code via SSH until you add an SSH key to your profile

为root用户准备SSH密钥（未设置私钥密码）

[root@client ~]# ssh-keygen -t ed25519 -C "harvey.mei@msn.com"
Generating public/private ed25519 key pair.
Enter file in which to save the key (/root/.ssh/id_ed25519): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_ed25519.
Your public key has been saved in /root/.ssh/id_ed25519.pub.
The key fingerprint is:
SHA256:zZYLuVxm+EDjPAHGjlgJjTGdkw0hrjMwOuLs6r0rrnU harvey.mei@msn.com
The key's randomart image is:
+--[ED25519 256]--+
| =*oOo |
| ..oO.o. |
|o .o + + |
|oo. . .+ B . |
|B S O |
|++ . @ . |
| o. E o o |

[root@client ~]#

为私钥文件添加或者修改密码

ssh-keygen -p -o -f <keyname>

复制公钥内容到GitLab账户设置中

[root@client ~]# cat .ssh/id_ed25519.pub 
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIHWIgmnrN7FGjKTdMxYE3y6py3SKp5cO0wnc2dlWNj5o harvey.mei@msn.com
[root@client ~]#
 

查看已导入的SSH公钥信息

测试用户root的SSH密钥有效性，按照提示将服务器端公钥存储在本地已知主机列表文件known_hosts文件中

[root@client ~]# ssh -i .ssh/id_ed25519 -T git@gitlab.licensebox.cn
The authenticity of host 'gitlab.licensebox.cn (47.75.246.214)' can't be established.
ECDSA key fingerprint is SHA256:s+kUB7fDvU43bDqTmukBOoSd/8o/gxzuQC/Kk1aYLio.
ECDSA key fingerprint is MD5:f4:2a:7f:58:6c:d8:d3:ee:90:3a:14:9f:f9:5b:d4:4c.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'gitlab.licensebox.cn,47.75.246.214' (ECDSA) to the list of known hosts.
Welcome to GitLab, @root!
[root@client ~]#

查看保留在本地的服务器端

[root@client ~]# cat .ssh/known_hosts

gitlab.licensebox.cn,47.75.246.214 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBLPz49yrtFCwkwt+5/kCXekab8jtrEmf8OpPyfjqtoOuPMlHbhH/rnlNxcicFMF+0U9AD/RIigglJh5SFgSYQ3A=
[root@client ~]#

本地操作系统安装Git客户端程序

[root@client ~]# git
-bash: git: command not found
[root@client ~]# yum -y install git

将仓库Clone到本地磁盘（无需再次验证身份）

[root@client ~]# git clone git@gitlab.licensebox.cn:root/licensebox.git 
Cloning into 'licensebox'...
remote: Enumerating objects: 3, done.
remote: Counting objects: 100% (3/3), done.
remote: Total 3 (delta 0), reused 0 (delta 0)
Receiving objects: 100% (3/3), done.

查看本地Git目录及文件内容，确认成功Clone仓库至本地磁盘

[root@client ~]# ls
licensebox
[root@client ~]# ls licensebox/
README.md
[root@client ~]# cat licensebox/README.md 
# licensebox
