第六章 GitHub 操作
一、创建远程仓库
二、远程仓库操作
| 命令名称 | 作用 |
|---|---|
| git remote -v | 查看当前所有远程地址别名 |
| git remote add 别名 远程地址 | 起别名 |
| git push 别名 分支 | 推送本地分支上的内容到远程仓库 |
| git clone 远程地址 | 将远程仓库的内容克隆到本地 |
| git pull 远程库地址别名 远程分支名 | 将远程仓库对于分支最新内容拉下来后与当前本地分支直接合并 |
1. 创建远程仓库别名
1.1 基本语法
- git remote -v 查看当前所有远程地址别名
- git remote add 别名 远程地址
1.2 案例实操
bash
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/SH0720 (master)
$ git remote -v
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/SH0720 (master)
$ git remote add ori https://github.com/atguiguyueyue/git-shTest.git
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/SH0720 (master)
$ git remote -v
ori https://github.com/atguiguyueyue/git-shTest.git (fetch)
ori https://github.com/atguiguyueyue/git-shTest.git (push)-
这个地址在创建完远程仓库后生成的连接，如图所示红框中
2. 推送本地分支到远程仓库
2.1 基本语法
- git push 别名 分支
2.2 案例实操
bash
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/SH0720 (master)
$ git push ori master
Logon failed, use ctrl+c to cancel basic credential prompt.
Username for 'https://github.com': atguiguyueyue
Counting objects: 3, done.
Delta compression using up to 12 threads.
Compressing objects: 100% (2/2), done.
Writing objects: 100% (3/3), 276 bytes | 276.00 KiB/s, done.
Total 3 (delta 0), reused 0 (delta 0)
To https://github.com/atguiguyueyue/git-shTest.git
* [new branch] master -> master- 此时发现已将我们 master 分支上的内容推送到 GitHub 创建的远程仓库。
3. 克隆远程仓库到本地
3.1 基本语法
- git clone 远程地址
3.2 案例实操
bash
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/pro-linghuchong
$ git clone https://github.com/atguiguyueyue/git-shTest.git
Cloning into 'git-shTest'...
remote: Enumerating objects: 3, done.
remote: Counting objects: 100% (3/3), done.
remote: Compressing objects: 100% (2/2), done.
remote: Total 3 (delta 0), reused 3 (delta 0), pack-reused 0
Unpacking objects: 100% (3/3), done.- https://github.com/atguiguyueyue/git-shTest.git
- 这个地址为远程仓库地址，克隆结果：初始化本地仓库
bash
# 创建远程仓库别名
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/pro-linghuchong/git-shTest
(master)
$ git remote -v
origin https://github.com/atguiguyueyue/git-shTest.git (fetch)
origin https://github.com/atguiguyueyue/git-shTest.git (push)- 小结：clone 会做如下操作。1、拉取代码。2、初始化本地仓库。3、创建别名
4. 邀请加入团队
4.1 选择邀请合作者
4.2 填入想要合作的人
4.3 复制地址并通过微信钉钉等方式发送给该用户，复制内容如下：
4.4 在 atguigulinghuchong 这个账号中的地址栏复制收到邀请的链接，点击接受邀请
4.5 成功之后可以在 atguigulinghuchong 这个账号上看到 git-Test 的远程仓库
4.6 令狐冲可以修改内容并 push 到远程仓库
bash
# 编辑 clone 下来的文件
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/pro-linghuchong/git-shTest
(master)
$ vim hello.txt
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/pro-linghuchong/git-shTest
(master)
$ cat hello.txt

# 将编辑好的文件添加到暂存区
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/pro-linghuchong/git-shTest(master)
$ git add hello.txt
# 将暂存区的文件上传到本地库
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/pro-linghuchong/git-shTest
(master)
$ git commit -m "lhc commit" hello.txt
[master 5dabe6b] lhc commit

7cb4d02..5dabe6b master -> master4.7 回到 atguiguyueyue 的 GitHub 远程仓库中可以看到，最后一次是 lhc 提交的
5. 拉取远程库内容
5.1 基本语法
- git pull 远程库地址别名 远程分支名
5.2 案例实操
bash
# 将远程仓库对于分支最新内容拉下来后与当前本地分支直接合并
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/SH0720 (master)
$ git pull ori master

1. 将远程仓库的地址复制发给邀请跨团队协作的人，比如东方不败
2. 在东方不败的 GitHub 账号里的地址栏复制收到的链接，然后点击 Fork 将项目叉到自己的本地仓库
- 叉入中...
- 叉成功后可以看到当前仓库信息
3. 东方不败就可以在线编辑叉取过来的文件
4. 编辑完毕后，填写描述信息并点击左下角绿色按钮提交
5. 接下来点击上方的 Pull 请求，并创建一个新的请求
6. 回到岳岳 GitHub 账号可以看到有一个 Pull request 请求
- 进入到聊天室，可以讨论代码相关内容
7. 如果代码没有问题，可以点击 Merge pull reque 合并代码
四、SSH 免密登录
- 我们可以看到远程仓库中还有一个 SSH 的地址，因此我们也可以使用 SSH 进行访问。
- 具体操作如下：
bash
# 进入当前用户的家目录
Layne@LAPTOP-Layne MINGW64 /d/Git-Space/SH0720 (master)
$ cd
# 删除.ssh 目录
Layne@LAPTOP-Layne MINGW64 ~
$ rm -rvf .ssh
removed '.ssh/known_hosts'
removed directory '.ssh'
# 运行命令生成.ssh 秘钥目录[注意：这里-C 这个参数是大写的 C]
Layne@LAPTOP-Layne MINGW64 ~
$ ssh-keygen -t rsa -C atguiguyueyue@aliyun.com
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Layne/.ssh/id_rsa):
Created directory '/c/Users/Layne/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Layne/.ssh/id_rsa.
Your public key has been saved in /c/Users/Layne/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:7CPfRLITKcYDhaqpEDeok7Atvwh2reRmpxxOC6dkY44
atguiguyueyue@aliyun.com
The key's randomart image is:

# 进入.ssh 目录查看文件列表
Layne@LAPTOP-Layne MINGW64 ~
$ cd .ssh

AGBFeW2+K81XrmkP27FrLI6lDef atguiguyueyue@aliyun.com- 复制 id_rsa.pub 文件内容，登录 GitHub，点击用户头像→Settings→SSH and GPG keys
- 接下来再往远程仓库 push 东西的时候使用 SSH 连接就不需要登录了。
