Git标签，Github远程版本库

Git标签

标签就代表着版本

git tag -a 指定版本号 -m "说明"

git tag -a 版本号 哈希值 -m "说明"对其它快照打标签

[root@kk data]# git tag -a v1.0 -m "tag v1.0"

[root@kk data]# git log --oneline --decorate
69941bd (HEAD, tag: v1.0, master) add file a
e16a96a add file a
[root@kk data]# git tag -a v1.1 e16a96a -m "tag v1.1 add a"

查看标签git tag

[root@kk data]# git tag
v1.0
v1.1

查看标签更改了什么git show 标签名

[root@kk data]# git show v1.0
tag v1.0

tag v1.0

commit 69941bd1c5c1ef452956b60ce69050d307e3ce79

    add file a

diff --git a/a b/a
new file mode 100644
index 0000000..e69de29

可以使用标签进行穿越

[root@kk data]# git log --oneline --decorate
69941bd (HEAD, tag: v1.0, master) add file a
e16a96a (tag: v1.1) add file a
[root@kk data]# git reset --hard v1.1
HEAD is now at e16a96a add file a
[root@kk data]# git log --oneline --decorate
e16a96a (HEAD, tag: v1.1, master) add file a

要是想要再穿越回去使用标签非常方便
[root@kk data]# git tag
v1.0
v1.1
[root@kk data]# git reflog
e16a96a HEAD@{0}: reset: moving to v1.1
69941bd HEAD@{1}: commit: add file a
e16a96a HEAD@{2}: commit (initial): add file a
[root@kk data]# git reset --hard v1.0
HEAD is now at 69941bd add file a
[root@kk data]# git log --oneline --decorate
69941bd (HEAD, tag: v1.0, master) add file a
e16a96a (tag: v1.1) add file a

删除标签git tag -d 标签名

[root@kk data]# git tag

v1.1
[root@kk data]# git tag -d v1.1
Deleted tag 'v1.1' (was 442133c)
[root@kk data]# git tag
v1.0

Github

 Github顾名思义是一个Git版本库的托管服务，是目前全球最大的软件仓库，拥有上百万的开发者用户也是软件开发和寻找资源的最佳途径，Github不仅可以托管各种Git版本仓库还拥有更美观的web界面，自己的代码可以被任何人克隆，使得开发者为开源项贡献代码变得更加容易，当然也可以付费购买私有库，高性价比的私有库可以并帮助很多团队和企业

• 注册用户
• 配置ssh-key
• 创建项目
• 克隆项目到本地
• 推送新代码到github

创新版本库

添加远程仓库名称为origin

[root@web01 data]# git remote add origin git@github.com:he30772818/git_data1.git

检查是否添加成功
[root@web01 data]# git remote
origin

推送master主干上origin远程仓库

git push -u origin master(选择了ssh要先做免密钥，不然推不上去）

[root@web01 ~]# cat .ssh/
authorized_keys  id_dsa.pub       id_rsa.pub       in_rsa.pub       
id_dsa           id_rsa           in_rsa           known_hosts      
[root@web01 ~]# cat .ssh/id_rsa.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCvc2TL8K1y+4AgWzuRD5SAJvnBrE+zfP68ICFjcy2U9azwrtyNnow1mFkFSBXrRiCD3PiTuhwfzEoJcZc9NMN6/q2o6kOKVA4bk04b+tMrYZRSDgy+e3geZ9pkl4fRii3h2U5cCLD4KJtfi4QTSTJLIbIZsTKI8yV5O7khj8TYJCy7QJeauWZxRmt9JLBtAshIkvdjwEUNYQRssf3mtvUHdODQ6qboM/C0e4C6JR6YvGqo81Ix4RfRQX3LRqmOUQfXRNTiMopQhBuO2kUa03xJhNnfrKT3JlcwdDe5a8KBegwyk1ZDWE8/Ep/A8+/ksTdfp1znslO56yXtC2TW73yV root@web01

登陆github进行查看git1_data远程仓储

在linux上想要下载github上的代码就可以执行

git clone xxxx             下载下来的文件目录名称和远程仓库名称一致

[root@kk data]# git clone git@github.com:he30772818/git_data1.git
