1、github.com 注册账户
2、在github上创建仓库
3、生成本地ssh key
[root@localhost ~]# ssh-keygen -t rsa -C 'maiya@163.com' # 邮箱要与github上注册的相同
[root@localhost ~]# cat .ssh/id_rsa.pub
ssh-rsa

4、复制以上的公钥,在github 中添加ssh key
5、测试
[root@localhost ~]# yum install git
........
[root@localhost ~]# ssh -T git@github.com
The authenticity of host 'github.com (13.250.177.223)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
RSA key fingerprint is MD5:16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'github.com,13.250.177.223' (RSA) to the list of known hosts.
Hi meteor! You've successfully authenticated, but GitHub does not provide shell access.
6、在本地添加远程仓库
[root@localhost ~]# git config --global user.name 'maiya_by'
[root@localhost ~]# git config --global user.email 'maiya@163.com'
[root@localhost ~]# git config --global color.ui true
[root@localhost ~]# git config --list | tail -3
user.name=maiya_by
user.email=maiya@163.com
color.ui=true
[root@localhost ~]#
[root@localhost ~]# ls .gitconfig
.gitconfig
[root@localhost ~]# cat .gitconfig
[user]
name = maiya_by
email = maiya@163.com
[color]
ui = true
7、连接远程仓库听方法
[root@localhost Python1804]# git remote -v
origin git@github.com:meteor/python1804.git (fetch)
origin git@github.com:meteor/python1804.git (push)
[root@localhost python1804]#git remote rm origin(如果连接远程的方式不是ssh,可以删除重新添加)
[root@localhost ~]# git remote add origin git@github.com:meteor/python1804.git
或
git remote add origin https://github.com/meteor/python1804.git
git push -u origin master
建立本地Git 服务器
[root@localhost ~]# useradd git ------------------创建一个git用户
[root@localhost ~]# mkdir /git‐root/
[root@localhost ~]# cd /git‐root/
[root@localhost git‐root]# git init ‐‐bare shell.git --------------初始化仓库
[root@localhost git‐root]# chown ‐R git.git shell.git ----------把文件的属主和属组改成git
[root@localhost git‐root]# su ‐ git --------------切换成git用户
生成密钥
[git@localhost ~]$ ssh‐keygen ‐t rsa ----------------生成密钥
[git@localhost ~]$ cd .ssh/
[git@localhost .ssh]$ cp id_rsa.pub authorized_keys-----------新建授权公钥串
[git@localhost .ssh]$ exit
克隆仓库
[root@localhost ~]# cd /opt/
[root@localhost opt]# git clone git@192.168.1.102:/git‐root/shell.git-----------克隆本地仓库
Cloning into 'shell'...
新建一个测试文件,进行推送
[root@localhost opt]# cd shell/
[root@localhost shell]# vim test1.sh
[root@localhost shell]# git add test1.sh
[root@localhost shell]# git commit ‐m 'first commit'
[root@localhost shell]# git push origin master
git常用的命令
git
git init #------------------初始化仓库
git clone https://github.com/kennethreitz/requests.gitCloning into 'requests'... #-----克隆建立远程库
git clone git@192.168.122.85:/git-root/liudelong.git #-------克隆建立本地库
git add * #------------提交
git commit -m "describe" #---------------对提交任务进行描述
git push origin master #----------------上传
查看状态
git status #------------------查看git 的状态
git status -s #-------------------查看git 的简要信息
显示信息:
A .gitignore
MM test2.py #------------------第一个M表示staging有修改，第二个M表示working directory有修改
git diff #检查数据是否一致
git diff #-------------默认git diff 只检查第二个标志位(即检查working directory与staging的数据是否一致
git diff HEAD #-------------------指针,检查working directory与history是否一致，HEAD指针就指向最后一次提交的内容
git diff --stat #-----------------输出简要信息
git diff --staged #-----------------表示检查stage与history中的数据是否一致
下载
git reset #----------------下载历史history中的最后一个版本致stage中
git checkout #--------------------把历史区的文件恢复到工作区-下载stage中的数据到working directory
git checkout HEAD #------------------从history中直接下载历史版本到working directory
git commit -am 'third commit' #-----------------直接由working directory提交到history
删除数据:
git rm file #--------------------删除文件
git rm --cached test2.py #---------------仅删除staging中的文件,此命令主要用来修改文件名
stash暂存
git stash #-------------暂存当前正在进行的工作
git stash list #----------------查看之前的暂存区
git stash pop #----------------取出上次的暂存
branch分支
git branch #----------------查看分支 (*表示当前的 branch)
git branch newidea #----------------创建分支
git checkout newidea #---------------切换新的分支
cat .git/HEAD #----------------查看当前HEAD指向newidea分支
ls .git/refs/heads/ #----------查看现有分支的存储情况
cat .git/refs/heads/* #---------------查看两个分支都指向同一个commit history
git branch -d newidea #-----------------删除指定分支
git checkout -b newcode #------------------参数-b 作用：检查如果没有branch则新建立
git merge newcode #--------------合并分支
git merge bugfix #--------------合并分支Auto-merging test1.py
