Git+GitHub 使用

GitHub 简单使用

在github上面新建好一个存储库,并配置好ssh-key作为连接github的秘钥


新建储存库


给GitHub添加SSH秘钥

GitHub上设置登录秘钥,主要是为了以后在服务器提交代码,可以免密直接上传。

  • 生成ssh秘钥

首先在需要提交代码的服务器上生成秘钥

# 生成ssh秘钥,生成的秘钥文件位置存在 /root/.ssh/ 目录下
$ ssh-keygen -t rsa -f /root/.ssh/id_rsa -P "" -q

# 查看并复制秘钥,然后复制到GitHub相关位置
$ cd /root/.ssh
$ cat id_rsa.pub
  • GitHub添加生成的秘钥


代码上传和拉取

  • 初始化git目录
git init
  • 添加远程仓库
git remote add origin git@github.com:wanhebin/test.git
  • 推送代码到远程仓库
git push -u origin master
  • 拉取代码
#克隆
git clone git@github.com:wanhebin/test.git

#直接拉取代码,但本地需要存在一个git仓库
git pull git@github.com:wanhebin/test.git

代码上传测试

  • 在新建目录中上传代码
[root@git ~]# mkdir /tmp/github && cd /tmp/github
[root@git github]# git init

[root@git github]# echo "# test" > README.md
