团队内协作

准备工作

使用Github，两个账号：etaon和etaoner

本地：

alma—>etaon
worker-03—>etaoner

Github已经不使用用户名和密码方式：

Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.

各自的ssh id_rsa.pub事先配置好，参考：

Connecting to GitHub with SSH - GitHub Docs

远程仓库操作

命令	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

Alma：

[root@Alma ~]# mkdir git-demo
[root@Alma ~]# cd git-demo/
[root@Alma git-demo]# git init
Initialized empty Git repository in /root/git-demo/.git/
[root@Alma git-demo]# touch readme.md

[root@Alma git-demo]# echo '1st to readme~~~' > readme.md
[root@Alma git-demo]# cat readme.md 
1st to readme~~~
[root@Alma git-demo]# git add  .
[root@Alma git-demo]# git commit readme.md -m 'The 1st'
[master (root-commit) 10132b0] The 1st
 1 file changed, 1 insertion(+)
 create mode 100644 readme.md
[root@Alma git-demo]# git reflog
10132b0 (HEAD -> master) HEAD@{0}: commit (initial): The 1st
[root@Alma git-demo]# echo '2nd to readme~~~' >> readme.md
[root@Alma git-demo]# cat readme.md 
1st to readme~~~
2nd to readme~~~
[root@Alma git-demo]# git add  .
[root@Alma git-demo]# git commit readme.md -m 'The 2st'
[master f38edd1] The 2st
 1 file changed, 1 insertion(+)
[root@Alma git-demo]# git reflog
f38edd1 (HEAD -> master) HEAD@{0}: commit: The 2st
10132b0 HEAD@{1}: commit (initial): The 1st 

#现在readme.md的内容是下面部分：

1st to readme~~~
2nd to readme~~~

在github中，用etaon账号建立仓库：git-demo

push内容到github

[root@Alma git-demo]# git branch -M main #创建分支（原有为master）
[root@Alma git-demo]# git checkout main #切换到main
Already on 'main'
[root@Alma git-demo]# git remote add git-demo https://github.com/etaon/git-demo.git#添加远程仓库，ssh方式
[root@Alma git-demo]# git remote -v#查看远程库
git-demo        git@github.com:etaon/git-demo.git (fetch)
git-demo        git@github.com:etaon/git-demo.git (push)
[root@Alma git-demo]# git branch -v#查看分支

[root@Alma git-demo]# git push git-demo main#push到远程库

在github使用etaon账户编辑readme.md

Alma pull:

[root@Alma git-demo]# git pull git-demo main
warning: Pulling without specifying how to reconcile divergent branches is
discouraged. You can squelch this message by running one of the following
commands sometime before your next pull:

  git config pull.rebase false  # merge (the default strategy)
  git config pull.rebase true   # rebase
  git config pull.ff only       # fast-forward only

You can replace "git config" with "git config --global" to set a default
preference for all repositories. You can also pass --rebase, --no-rebase,
or --ff-only on the command line to override the configured default per
invocation.

Worker-03：clone到本地git-demo库

[root@worker-03 ~]# git config --global user.name etaoner
[root@worker-03 ~]# git config --global user.email etaoner@163.com
[root@worker-03 ~]# git clone https://github.com/etaon/git-demo.git

[root@worker-03 git-demo]# git remote -v
**origin**  https://github.com/etaon/git-demo.git (fetch)
**origin**  https://github.com/etaon/git-demo.git (push)

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-默认为origin

邀请合作者

etaon在github邀请合作者：etaoner

仓库—>Settings—>Collaborators—>Manage access—>Add people

复制Invite链接，发送给etaoner

合作者加入

合作者打开链接并选择同意

此时，在Worker-03上的修改可以push，（使用token登录的etaoner的账号）

[root@worker-03 git-demo]# git push git@github.com:etaon/git-demo.git

跨团队协作

使用另外一个账号joinini来表示团队外成员

fork仓库

可以看到：

joinini / git-demo -->名字

forked from etaon/git-demo -->来源

joinini在线编辑

提交：

创建一个pull request

提交以后：

在joinini账户中，发现转到etaon/git-demo

etaon账户的操作

在etaon的账户中可以看到pull request

进入request还可以发起聊天

joinini可以看到：

合并代码：

得到结果

etaon可以在alma上更新本地库

[root@Alma git-demo]# git pull git-demo main
