一、创建标签
标签tag，是对某次 commit 的⼀个标识，相当于起了⼀个别名。
相较于难以记住的 commit id ， tag 很好的解决这个问题，因为 tag ⼀定要给⼀个让⼈容易记住，且有意义的名字。当我们需要回退到某个重要版本时，直接使⽤标签就能很快定位到。
# 切换到需要打标签的分支上，用 git tag [name] 给分支打标签
# 用 git tag 查看标签
(base) [root@localhost git-learning]# git branch
* master
(base) [root@localhost git-learning]# git tag v1.0
(base) [root@localhost git-learning]# git tag
v1.0
(base) [root@localhost git-learning]## 默认标签是打在最新提交的 commit 上，我们也可以指定 commit id 打标签
(base) [root@localhost git-learning]# git log --pretty=oneline --abbrev-commit

dd56a90 Initial commit
(base) [root@localhost git-learning]# git tag v0.0 1ccab43
(base) [root@localhost git-learning]# git tag
v0.0
v1.0
(base) [root@localhost git-learning]#二、查看标签
git tag 查看标签不是按时间顺序列出，而是按字母排列的。
# git show [tagname] 查看标签具体信息
(base) [root@localhost git-learning]# git show v0.0
