管理多个SSH的密钥
大家访问github或者gitlab的时候，还是使用ssh比较方便，使用https方式需要输入用户名密码，但是同时有github和gitlab的时候就比较麻烦了
下面分享一下同时管理多个ssh密钥的方法
1.大家生成ssh key的时候一般用以下命令
~ ssh-keygen -t rsa -C "mail@mail.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/username/.ssh/id_rsa): /Users/username/.ssh/id_rsa_github
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/username/.ssh/id_rsa_github.
Your public key has been saved in /Users/username/.ssh/id_rsa_github.pub.
The key fingerprint is:
SHA256:D3ew605ht8B9NMCvadetvF6wcG//JwUrNbdegueAXQY/3n8 username@MBP
The key's randomart image is:
+---[RSA 2048]----+
| |
| |
| . . |
| . o o |
| So* = = |
| B+% x o |
| .@o& = .|
| *.*+B.oE|
| .oB*ooo +|
+----[SHA256]-----+
可以看到，在Enter file in which to save the key (/Users/username/.ssh/id_rsa):这句提示，如果不输入的话，默认生成key就放在了/Users/username/.ssh/id_rsa这个路径下，我们可以自己输入一个路径，比如：/Users/username/.ssh/id_rsa_github
同样生成一个id_rsa_gitlab密钥
2.我们把生成好的私钥添加到ssh-agent中
ssh-add ~/.ssh/id_rsa_github
ssh-add ~/.ssh/id_rsa_gitlab
3.将对应的公钥文件id_rsa_github.pub添加到github，将id_rsa_gitlab.pub添加到gitlab上。
4.在~/.ssh/目录下添加config文件
touch ~/.ssh/config
5.修改config文件
#aaa (github 配置)
Host github
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_github
#aaa (gitlab 配置)
Host gitlab
HostName gitlab.com
User git
IdentityFile ~/.ssh/id_rsa_gitlab
6.测试一下
ssh -T git@github.com
以后操作就可以使用ssh方式来访问仓库了。
