commit最近记录3
找到最近若干次的commit记录，假如我们需要舍弃记录1和记录2，希望直接把远端的分枝回滚到记录3。
强制回滚
$ git reset --hard 0279a568
HEAD is now at 0279a56 commit最近记录3
# 如果只是要回到之前一个提交记录
# git reset --hard HEAD^1
其中--hard后面的八位字符时上面提交记录里的commit后面的一串的前八位。
$ git status
On branch master
Your branch is behind 'origin/master' by 2 commits, and can be fast-forwarded.
(use "git pull" to update your local branch)
查看得知本地回滚成功，但是远程的库还没回滚。
远程回滚
$ git push -f origin master
Total 0 (delta 0), reused 0 (delta 0)
To git.souche.com:fis-projects/dafengche-maintain-query-f2e.git
+ 16577b2...0279a56 master -> master (forced update)
成功的提示如上。但是如果执行后不成功，提示如下的话，则需要上 gitlab／github 上设置 Protected Branches 了，为的是去除本分支的保护后才能强制覆盖提交。
$ git push -f origin master
Total 0 (delta 0), reused 0 (delta 0)
remote: GitLab: You are not allowed to force push code to a protected branch on this project.
To git.souche.com:fis-projects/dafengche-maintain-query-f2e.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@git.souche.com:fis-projects/dafengche-maintain-query-f2e.git'
