1.前因

个人常用github，公司使用gitee，为了不同环境的使用方便。下文以这两个网站示例设置多个SSH。

2.生成SSH公钥私钥

//1.进入ssh目录
$ cd ~/.ssh 
//2.创建公私钥，输入对应gitee、github邮箱
$ ssh-keygen -t rsa -C "youremail@email.com" 
Generating public/private rsa key pair.
//3.输入区分名字,例如 github_id_rsa 、 gitee_rsa
Enter file in which to save the key (/Users/dsen/.ssh/id_rsa):github_id_rsa
//4.设置密码，我这里为了方便，没有使用密码，直接按回车enter,
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in github_id_rsa.
Your public key has been saved in github_id_rsa.pub.
The key fingerprint is:
SHA256:mvlMQCBQqa1TQjtSduYPIqJbxRJidpqAwj9bR5KQ02E youremail@email.com
The key's randomart image is:
+---[RSA 2048]----+
|+ooo=Eo          |
|====+= .         |
|****. +          |
|*==o=o .         |
|+=.++oo S        |
|+ ..  .=         |
| +    + .        |
|.      +         |
|        o        |
+----[SHA256]-----+

3.创建config文件

在 ~/.ssh 目录创建一个config文件

1

3
vim config
或
touch config

4.config文件写入内容

# github
  Host github.com
  HostName github.com
# github对应的email或者用户名
  User xxxxx@gmail.com
  PreferredAuthentications publickey
# github对应的私钥完整路径,没有pub后缀
  IdentityFile ~/.ssh/github_id_rsa

# gitee
  Host gitee.com
# gitee对应的email
  User xxxx@163.com
  PreferredAuthentications publickey
# gitee对应的私钥完整路径,没有pub后缀
  IdentityFile ~/.ssh/gitee_id_rsa

5.配置网站SSH公钥

a.打开网址，填写公钥标题，用来识别。
https://github.com/settings/keys
https://gitee.com/profile/sshkeys
b.填写公钥内容。

//查看公钥，把输出的内容全部填入的网站SSH公钥内容中，ssh-rsa开头，email结尾。
$ cat github_id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDTa570Bo0BptLJKbXxVrMfe7xv6I9dFY7GTh7LQcaaYe9G7miT0HuX+PS1eu4qmYAeY7HmEsHFGOfOkcq+d5CYYLabUFCuW0BtQEgniQuUr9Aumr9R6nhUbyQ+ldFAUkOqmxP3upUSPbilCzfQ2hBpAik2zZ2yeiDTBKXXq5HU1c4W9c3pbTetUYr36QgfBo6XuK8zlt24DwNmjplOasUhiejK68KVBgmsPuIeU71b8aZcdn9oTF0BIjapLQ0n4F180Oexp0PHvojN8k13oglgkb+ljtrPa8tPbb4xd+j0gr3DM8aG+kF704yuTKwKlVIARZpbgdzc4SSaH0+zr4yN youremail@email.com

6. 测试

ssh -T git@github.com
//成功
Hi xxx! You've successfully authenticated, but GitHub does not provide shell access.

ssh -T git@gitee.com       
//成功                                                                                                                       
Hi xxx! You've successfully authenticated, but GITEE.COM does not provide shell access.

7.错误

$ ssh -T git@gitee.com
Permission denied, please try again

检查命令、config文件是否拼写错误。2.检查网站是否配置公钥。3.若~/.ssh目录存在known_hosts文件，打开 known_hosts ,删除对应的ip、网址记录。

WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

ssh-keygen -R “you server hostname or ip”
