Git/Github使用笔记(一)——如何生成SSH key及访问Github
一、检查SSH key是否存在 在终端输入:
ls -al ~/.ssh
如果没有,终端显示如下: No such file or directory 如果已经存在,则会显示id_rsa和id_rsa.pub 二、生成新的SSH key 在终端输入:
ssh-keygen -t rsa -C "your_email@example.com"
其中your_email@example.com为你在Github注册时的邮箱 成功后终端显示如下: Generating public/private rsa key pair. Enter file in which to save the key (/Users/xxx/.ssh/id_rsa): 提示你保存.ssh/id_rsa的路径,这里直接enter Created directory ‘/Users/xxx/.ssh’. Enter passphrase (empty for no passphrase): 提示输入passphrase,每次与Github通信都会要求输入passphrase,以避免某些“失误”,建议输入 成功后终端显示: Your identification has been saved in /Users/xxx/.ssh/id_rsa. Your public key has been saved in /Users/xxx/.ssh/id_rsa.pub. The key fingerprint is: 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48 your_email@example.com The key’s randomart image is:(后面图形省略) 三、添加key到SSH 输入命令:
ssh-add ~/.ssh/id_rsa
此时会要求输入passphrase,输入步骤二中填的passphrase 成功后,终端显示: Identity added: /Users/xxx/.ssh/id_rsa (/Users/xxx/.ssh/id_rsa) 最后,在/Users/xxx/.ssh/生成两个文件,id_rsa和id_rsa.pub 此时,SSH key已经生成成功 四、添加SSH key到Github 1.复制id_rsa.pub中的所有内容 打开id_rsa.pub,终端命令:
cat ~/.ssh/id_rsa.pub
手动复制所有内容 或者直接输入命令复制id_rsa.pub中的所有内容,终端命令: pbcopy < ~/.ssh/id_rsa.pub 2.登录Github 打开个人Settings–>SSH keys–>Add SSH key Title 随便写 Key 粘贴之前复制的内容 这样SSH key就添加的Github 五、检测SSH key 输入命令:
ssh git@github.com
此时会验证SSH key是否可以访问Gitbub 成功显示如下: Hi your_name! You’ve successfully authenticated, but GitHub does not provide shell access. Connection to github.com closed.
