Git遠端庫版本回滾

在git的一般使用中，如果發現錯誤的將不想staging的檔案add進入index之後，想回退取消,這就叫做git程式碼庫回滾: 指的是將程式碼庫某分支退回到以前的某個commit id。可以使用命令：git reset HEAD <file>...，同時git add完畢之後，git也會做相應的提示，Git reset 是Git最常用的命令之一，也是最危險最容易誤用的命令。 用法參考 Git學習筆記03--git reset
【原生程式碼庫回滾】：

git reset --hard commit-id :回滾到commit-id，講commit-id之後提交的commit都去除

git reset --hard HEAD~3：將最近3次的提交回滾
【遠端程式碼庫回滾】：

這個是重點要說的內容，過程比本地回滾要複雜

應用場景：自動部署系統釋出後發現問題，需要回滾到某一個commit，再重新發布

原理：先將本地分支退回到某個commit，刪除遠端分支，再重新push本地分支

操作步驟：

1、git checkout the_branch
2、git pull
D:\FitProject\NPS>git pull

From xxxxxxxxxxxx
    fe0d037..d159d4d  stable_chh_1127 -> origin/stable_chh_1127

Already up-to-date.
3、git branch the_branch_backup //備份一下這個分支當前的情況
D:\FitProject\NPS>git branch Geffdev_0926_backup

4、git reset --hard the_commit_id //把the_branch本地回滾到the_commit_id
D:\FitProject\NPS>git reset --hard 56f7c0d56befd4cad99a6017062824e073b56c01

HEAD is now at 56f7c0d 封裝付款體現Relay介面
5、git push origin :the_branch //刪除遠端 the_branch

6、git push origin the_branch //用回滾後的本地分支重新建立遠端分支
D:\FitProject\NPS>git push origin : Geffdev_0926

error: failed to push some refs to xxxxxx

hint: Updates were rejected because the tip of your current branch is behind

hint: its remote counterpart. Integrate the remote changes (e.g.

hint: 'git pull ...') before pushing again.

hint: See the 'Note about fast-forwards' in 'git push --help' for details.


D:\FitProject\NPS>git push origin  Geffdev_0926

Total 0 (delta 0), reused 0 (delta 0)

7、git push origin :the_branch_backup //如果前面都成功了，刪除這個備份分支
