git安装步骤

1. 安装git

   yum -y install git git-core

   git version #查看git版本，确认安装是否成功。

2. 生成私钥和公钥

   cd ~/.ssh

   ls

   ssh-keygen -t rsa -C "*****@163.com" //不要输入密码，否则以后很麻烦

   cat ~/.ssh/id_rsa.pub  # 查看公钥

3. 修改私钥权限

   chmod 600 ~/.ssh/id_rsa.

   chown gelu:staff ~/.ssh/id_rsa

4. 注册github，并在account set内设置ssh key

   github地址： https://github.com

5. 登陆github

   ssh -T git@github.com # 会看到：Hi gelu8888! You've successfully authenticated, but GitHub does not provide shell access.
