GitHub-创建仓库与本地同步

1. 在Linux上安装Git

 [root@mini05 ~]# yum install -y git
 ………………

2. 本地创建ssh-key信息

 [root@mini05 ~]# ssh-keygen -t rsa
 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:ACvHut11cMKDaL1QzsrL3x23OyUl9cd7+kLfFW30cLM root@mini05
 The key's randomart image is:
 +---[RSA ]----+
 |    . .          |
 |   . O o      o.o|
 |  . B * = .  . *=|
 |   * o o =  . .EB|

 |   + o . .  . o.o|
 |  . + .   . .+ o+|
 |     . . . o..o o|

3. 在GitHub上添加SSH Keys信息

4. 在GitHub上新建仓库并本地克隆仓库

4.1. GitHub新建仓库

git@github.com:zhanglianghhh/zhangtest.git

4.2. 本地克隆GitHub仓库

 [root@mini05 git_repository]# pwd  # 注意目录
 /opt/git_repository
 [root@mini05 git_repository]# git clone git@github.com:zhanglianghhh/zhangtest.git
 Cloning into 'zhangtest'...
 The authenticity of host 'github.com (192.30.253.113)' can't be established.
 RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.

 [root@mini05 git_repository]# ll
 total
 drwxr-xr-x  root root  Sep  : zhangtest

5. 本地建仓库并同步到GitHub上

5.1. 本地建仓库

 [root@mini05 gittest]# pwd
 /opt/git_repository/gittest
 [root@mini05 gittest]# git init
 Initialized empty Git repository in /opt/git_repository/gittest/.git/
 [root@mini05 gittest]# ll -a
 total
 drwxr-xr-x  root root   Oct   : .
 drwxr-xr-x  root root   Oct   : ..
 drwxr-xr-x  root root  Oct   : .git
 [root@mini05 gittest]# cat test.info 

 [root@mini05 gittest]# git add .  # 添加到暂存区
 [root@mini05 gittest]# git commit -m "add"  # 提交到仓库
 [master (root-commit) 1c47050] add
   file changed,  insertions(+)
  create mode  test.info

5.3. GitHub新建仓库

5.3. 本地仓库关联GitHub

 [root@mini05 gittest]# git remote add origin git@github.com:zhanglianghhh/gittest.git
 [root@mini05 gittest]# git push -u origin master  # 第一次提交时 后续提交：  git push origin master
 Counting objects: , done.
 Writing objects: % (/),  bytes |  bytes/s, done.

 remote:
 To git@github.com:zhanglianghhh/gittest.git
  * [new branch]      master -> master
 Branch master set up to track remote branch master from origin.

6. Git仓库的更新

6.1. GitHub有更新之后本地更新仓库

 [root@mini05 zhangtest]# pwd  # 注意所在目录
 /opt/git_repository/zhangtest
 [root@mini05 zhangtest]# ll
 total
 -rw-r--r--  root root  Sep  : README.md
 [root@mini05 zhangtest]# cat README.md
 # zhangtest
 zhangtest
 [root@mini05 zhangtest]# git pull  # 本地更新
 remote: Counting objects: , done.
 remote: Total  (delta ), reused  (delta ), pack-reused
 Unpacking objects: % (/), done.
 From github.com:zhanglianghhh/zhangtest
  * branch            HEAD       -> FETCH_HEAD

6.2. 本地更新并提交到本地仓库

 [root@mini05 zhangtest]# pwd
 /opt/git_repository/zhangtest
 [root@mini05 zhangtest]# git status  # 查看仓库当前的状态----可见文件没有修改，也没有需要提交的
 # On branch master
 # Your branch is ahead of 'origin/master' by  commit.
 #   (use "git push" to publish your local commits)
 #
 nothing to commit, working directory clean
 [root@mini05 zhangtest]# cat README.md  # 更新的文件
