git回滚代码

有时我们需要回滚git上已经提交的代码，特别是已经提交到github上的代码。可以使用如下步骤：

1、 git reflog

$ git reflog
1bd6100 (HEAD -> master) HEAD@{0}: commit: Site updated: 2018-05-10 12:20:40
f681615 HEAD@{1}: commit: Site updated: 2018-04-25 19:31:25
78f096f HEAD@{2}: commit: Site updated: 2018-04-25 19:11:23
14b480b HEAD@{3}: commit: Site updated: 2018-04-24 20:01:27
  COPY

2、 git reset --hard version

$ git reset --hard f681615
HEAD is now at f681615 Site updated: 2018-04-25 19:31:25
  COPY

3、 git log

$ git log
commit f68161540b8c3400c4ab4a35eef67039c732781d (HEAD -> master)

    Site updated: 2018-04-25 19:31:25
  COPY

4、 git push --force

$ git push --force

To github.com:drunkdream/xxx.git
 + 1bd6100...f681615 master -> master (forced update)
  COPY
