免登录配置
在ssh终端中输入
ssh-keygen -t rsa
执行后 一路回车(3次)
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/XXX/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
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:
SHA256:qw8xn3RgwjcPYcVjcAbbIYusAC2sDrBlHAY7B2IykmA XXX@XXX-MacBook-Pro.local
The key's randomart image is:
+---[RSA 2048]----+
|XBE. *== |
|OO= o o O+. |
|==o = O.. |
|+o . . + = |
|o . o S o |
| . = + |
| . + |
| o |
| ... |
+----[SHA256]-----+
然后登录你GitHub账号 依次点击"Setting" -> "SSH Keys"->"New SSH key"
将id_rsa.pub中的内容copy到 key那一栏 title是个简单的说明
最后测试是否成功！！
ssh -T git@github.com
会出现
The authenticity of host 'github.com (52.74.223.119)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)?
yes 回车
Warning: Permanently added 'github.com,52.74.223.119' (RSA) to the list of known hosts.
Hi XXXX! You've successfully authenticated, but GitHub does not provide shell access.
那么你就成功的完成了免登录配置
多账号登录
如果你有好几个git账号那么你要下面操作了
在ssh终端中输入
ssh-keygen -t rsa -C "你的github账号" -f ~/.ssh/秘钥文件名称(例如: github_1_rsa)
执行后 一路回车(2次 ,因为你已经设置了名称)
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/XXX/.ssh/github_1_rsa.
Your public key has been saved in /Users/XXX/.ssh/github_1_rsa.pub.
The key fingerprint is:
SHA256:dZFCgwLaaDxVW7W+v4UfXeyB8ysKr5GRg9f+yqcf1vX 1aa@company.com(你的github账号)
The key's randomart image is:
+---[RSA 2048]----+

| .S=.. o .o|
| . =. .=oo|
| +...oo+o|
| =.o=..o|
| ..*O+o.E|
+----[SHA256]-----+
然后和上面操作一样将 github_1_rsa.pub 的内容加入 GitHub的ssh管理器中
给ssh 创建配置文件
vim ~/.shh/config (默认是没有该文件的)
## 配置写入
Host github.com(自定义名称)
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
Host my.github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/github_1_rsa
使用：
// 原来写法
git clone git@github.com: github用户名/testgit.git
// 现在写法
git clone git@my.github.com: my的github的用户名/testgit.git
github提示Permission denied (publickey)
极大多数情况是由于github账号没有设置ssh公钥信息所致。 前往 GitHub 网站的"account settings"
如果你在新建秘钥的时候使用了自定义的名称，比如github_rsa，你需要再配置一个config文件
cd ~/.ssh
vi config
Host github.com
HostName github.com
User git
IdentityFile ~/.ssh/github_rsa
