设置 github 作为 git 的远程仓库

标签（空格分隔）： git github

1 测验SSH公钥是否添加到Github账户中

[ahcj@localhost ~]# ssh -T git@github.com
Warning: Permanently added the RSA host key for IP address '192.30.255.113' to the list of known hosts.
Permission denied (publickey).

上面的例子显示登录失败，这是因为我们还未在GitHub账户中添加SSH公钥。这时需要在本地创建SSH公钥，然后将生成的SSH公钥的文件内容添加到Github帐号上去。

2 生成SSH公钥

[ahcj@localhost ~]ssh-keygen -t rsa -C "your_email@youremail.com"

一路按 enter 键，最后会在.ssh目录生产两个文件：id_rsa和id_rsa.pub。
其中_{/.ssh/id_rsa是私钥文件，}/.ssh/id_rsa.pub是公钥文件。

3 添加SSH公钥

# 将公钥输出到剪切板
[ahcj@localhost ~]cat  ~/.ssh/id_rsa.pub | xclip -selection clipboard

# 或者使用 vim 打开 复制所有内容
[ahcj@localhost ~]vim  ~/.ssh/id_rsa.pub

登录你的Github帐号后

1. 点击右上方的Accounting settings图标
2. 选择 SSH keys
3. 点击 Add SSH key
4. 在Title里填一个你自己喜欢的名称，然后将上面拷贝的~/.ssh/id_rsa.pub文件内容粘帖到Key中
5. 点击“add key”按钮

4 测试SSH连接Github

[ahcj@localhost ~]$ ssh -T git@github.com
Warning: Permanently added the RSA host key for IP address '192.30.255.113' to the list of known hosts.
Hi xingchuan! You've successfully authenticated, but GitHub does not provide shell access.

5 设置git用户名与邮箱

[ahcj@localhost ~]git config --global user.name "Your Name Here"
[ahcj@localhost ~]git config --global user.email "your_email@example.com"
