SSH key提供了一种与GitHub通信的方式,通过这种方式,能够在不输入密码的情况下,将GitHub作为自己的remote端服务器,进行版本控制
输入下面的命令,如果有文件id_rsa.pub 或 id_dsa.pub,则直接进入步骤3将SSH key添加到GitHub中,否则进入第二步生成SSH key
ls -al ~/.ssh # Lists the files in your .ssh directory, if they exist第一步:生成public/private rsa key pair 在命令行中输入ssh-keygen -t rsa -C "your_email@example.com"
默认会在相应路径下(/your_home_path)生成id_rsa和id_rsa.pub两个文件,如下面代码所示
ssh-keygen -t rsa -C "your_email@example.com" # Creates a new ssh key using the provided email Generating public/private rsa key pair. Enter file in which to save the key (/your_home_path/.ssh/id_rsa):第二步:输入passphrase(本步骤可以跳过)
设置passphrase后,进行版本控制时,每次与GitHub通信都会要求输入passphrase,以避免某些“失误”
Enter passphrase (empty for no passphrase): [Type a passphrase] Enter same passphrase again: [Type passphrase again]sample result:
Your identification has been saved in /your_home_path/.ssh/id_rsa. Your public key has been saved in /your_home_path/.ssh/id_rsa.pub. The key fingerprint is: #01:0f:f4:3b:ca:85:d6:17:a1:7d:f0:68:9d:f0:a2:db your_email@example.com第三步:将新生成的key添加到ssh-agent中:
# start the ssh-agent in the background eval "$(ssh-agent -s)" Agent pid 59566 ssh-add ~/.ssh/id_rsa本文首载于Gevin's blog
