## 新建一个目录 cd 进去，然后执行clone代码root@yt:~# mkdir my-gitlab-coderoot@yt:~# cd my-gitlab-code/root@yt:~/my-gitlab-code# pwd/root/my-gitlab-coderoot@yt:~/my-gitlab-code# git clone http://192.168.131.130/my-app1/app1-1.gitCloning into 'app1-1'...Username for 'http://192.168.131.130': user2Password for 'http://user2@192.168.131.130': remote: Enumerating objects: 9, done.remote: Counting objects: 100% (9/9), done.remote: Compressing objects: 100% (6/6), done.remote: Total 9 (delta 0), reused 0 (delta 0), pack-reused 0Unpacking objects: 100% (9/9), 3.26 KiB | 3.26 MiB/s, done.root@yt:~/my-gitlab-code# lsapp1-1

## 首先执行 git add . 将变化的文件放入暂存区root@yt:~/my-gitlab-code/app1-1# git add .## 然后执行 git commit -m "xx" 编写提交变更信息注释 ， 注意到这里位置都是属于再本地的修改，不会影响到代码仓库的内容root@yt:~/my-gitlab-code/app1-1# git commit -m "xxx"[main f61e0a1] xxx Committer: root <root@1395001789@qq.com>Your name and email address were configured automatically basedon your username and hostname.
