首先配置ssh密鑰

克隆項目

• 配置兩臺主機（一臺本地mac，一臺云服務器）通過這樣的方式模擬多人開發。

創建分支

[root@ ~/Git_test_多人協作和沖突合并/branch_test]$ ls README.md [root@ ~/Git_test_多人協作和沖突合并/branch_test]$ git branch * master [root@ ~/Git_test_多人協作和沖突合并/branch_test]$ git branch yun [root@ ~/Git_test_多人協作和沖突合并/branch_test]$ git branch * masteryun [root@ ~/Git_test_多人協作和沖突合并/branch_test]$

轉移到分支并在分支添加項目

[root@ ~/branch_test]$ ls README.md [root@ ~/branch_test]$ git checkout yun 切換到分支 'yun' [root@ ~/branch_test]$ git branchmaster * yun [root@ ~/branch_test]$ ls README.md [root@ ~/branch_test]$ touch yun1.c [root@ ~/branch_test]$ ls README.md yun1.c [root@ ~/branch_test]$ git add yun1.c [root@ ~/branch_test]$ git commit -m "yun1.c"*** Please tell me who you are.Rungit config --global user.email "you@example.com"git config --global user.name "Your Name"to set your account's default identity. Omit --global to set the identity only in this repository.fatal: empty ident name not allowed

要提交自己的用戶名和郵箱才可以繼續

• 提交完畢后

[root@ ~/branch_test]$ git commit -m "yun1.c" [yun eb267c4] yun1.c1 file changed, 0 insertions(+), 0 deletions(-)create mode 100644 yun1.c

沖突測試

master

• 首先使用yun提交一段代碼

[root@ ~/branch_test]$ git branch * masteroriginyun [root@ ~/branch_test]$ ls README.md yun1.c [root@ ~/branch_test]$ cat yun1.c hello world [root@ ~/branch_test]$ git push origin master Total 0 (delta 0), reused 0 (delta 0) To git@git.github.com:kouhaozhe/branch_test.giteb267c4..025a01e master -> master

• 這是master的yun1.c文件就有了一段代碼

yun1.c 12 Bytes hello world

• 我們使用mac進行提交

khz:branch_test kouhz$ ls README.md yun1.c khz:branch_test kouhz$ vim yun1.c khz:branch_test kouhz$ cat yun1.c HELLO WORLDkhz:branch_test kouhz$ git add yun1.c khz:branch_test kouhz$ git commit -m "HELLO WORLD" [master 75da4f2] HELLO WORLD1 file changed, 1 insertion(+) khz:branch_test kouhz$ git push To git.github.com:kouhaozhe/branch_test.git! [rejected] master -> master (fetch first) error: failed to push some refs to 'git@git.github.com:kouhaozhe/branch_test.git' hint: Updates were rejected because the remote contains work that you do hint: not have locally. This is usually caused by another repository pushing hint: to the same ref. You may want to first integrate the remote changes hint: (e.g., 'git pull ...') before pushing again. hint: See the 'Note about fast-forwards' in 'git push --help' for details. khz:branch_test kouhz$

沖突時我們要先git pull再git push

• git pull
• git diff 查看文件的不同

<<<<<<< HEAD HELLO WORLD ======= hello world >>>>>>> 8d4d57c701bfbda71cc442caf2017c01437a80d1

其他分支

yun 分支添加文字并提交

[root@ ~/branch_test]$ git branchmaster * yun [root@ ~/branch_test]$ ls README.md yun1.c [root@ ~/branch_test]$ vim yun1.c [root@ ~/branch_test]$ cat yun1.c yun hello[root@ ~/branch_test]$ git add yun1.c [root@ ~/branch_test]$ git commit -m "yun yun1.c" [yun 4d7c92c] yun yun1.c1 file changed, 1 insertion(+), 1 deletion(-) [root@ ~/branch_test]$ git push Counting objects: 5, done.

• 這時網頁已經有了我們提交的帶著，我們切換到另一臺機器
  另一臺電腦除了自己創建的分支，看不見另一臺電腦創建的分支，這時使用命令

khz:branch_test kouhz$ git branchmac * master

同步之后沒有yun這個分支，操作命令
切換另一臺主機創建的分支

git checkout -b yun origin/yun

Tips:
error: you need to resolve your current index first

khz:branch_test kouhz$ git reset --merge
khz:branch_test kouhz$ git checkout -b yun origin/yun
Branch ‘yun’ set up to track remote branch ‘yun’ from ‘origin’.
Switched to a new branch ‘yun’

在進行添加代碼

khz:branch_test kouhz$ cat yun1.c <<<<<<< HEAD hello world HELLO WORLD ======= yun hello >>>>>>> 4d7c92c5686128aa3c99c25f3dbfdbbd88f8cf5e khz:branch_test kouhz$ vim yun1.c khz:branch_test kouhz$ cat yun1.c yun hello hello world HELLO WORLDkhz:branch_test kouhz$ git add yun1.c khz:branch_test kouhz$ git commit -m "mac" [yun ae006aa] mac khz:branch_test kouhz$ git push origin yun Counting objects: 6, done.

切換到另一臺主機

• 進行git pull操作，結果失敗了！原因是沒有指定本地dev分支與遠程origin/dev分支的鏈接

[root@ ~/branch_test]$ git pull remote: Counting objects: 6, done. remote: Compressing objects: 100% (4/4), done. remote: Total 6 (delta 0), reused 0 (delta 0) Unpacking objects: 100% (6/6), done. 來自 git.github.com:kouhaozhe/branch_test4d7c92c..ae006aa yun -> origin/yun There is no tracking information for the current branch. Please specify which branch you want to merge with. See git-pull(1) for detailsgit pull <remote> <branch>If you wish to set tracking information for this branch you can do so with:git branch --set-upstream-to=origin/<branch> yun

• 我們按照提示進行操作
  git branch --set-upstream-to=origin/ yun
  git branch --set-upstream-to=origin/yun yun

這時操作就成功了

[root@ ~/branch_test]$ cat yun1.c yun hello [root@ ~/branch_test]$ git pull 更新 4d7c92c..ae006aa Fast-forwardyun1.c | 2 ++1 file changed, 2 insertions(+) [root@ ~/Git_test_多人協作和沖突合并/bra nch_test]$ cat yun1.c yun hello hello world HELLO WORLD

如何一次性永久保存密碼

git config --global credential.helper store
