Mac一台终端-多个ssh-key配置
1、生成SSH-Key
$ ssh-keygen -t rsa -C "youremail@xxx.com" -f ~/.ssh/id_rsa_github
$ ssh-keygen -t rsa -C "youremail@xxx.com" -f ~/.ssh/id_rsa_gitlab
2、查看公钥
$ cat ~/.ssh/id_rsa_github.pub
$ cat ~/.ssh/id_rsa_gitlab.pub
3、将公钥内容复制粘贴至github/gitlab SSH公钥
4、添加私钥
$ ssh-add ~/.ssh/id_rsa_github
$ ssh-add ~/.ssh/id_rsa_gitlab
5、添加配置文件
//进入ssh目录
$ cd ~/.ssh
//新建config文件
$ touch config
6、编辑config文件
//打开ssh文件
$ open ~/.ssh
打开config文件进行如下编辑
# github
Host github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_github
# 如果出现22的报错请用这个
Host github.com
HostName ssh.github.com
Port 443
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_github
# gitlab
Host gitlab.com
HostName gitlab.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_gitlab
#用于自动添加ssh
Host *
UseKeychain yes
AddKeysToAgent yes
IdentityFile ~/.ssh/id_rsa_github
IdentityFile ~/.ssh/id_rsa_gitlab
# 配置文件参数
# Host : Host可以看作是一个你要识别的模式，对识别的模式，进行配置对应的的主机名和ssh文件
# HostName : 要登录主机的主机名
# IdentityFile : 指明上面User对应的identityFile路径
编辑好后 command + s保存下，这样就OK了
7、测试
$ ssh -T git@github.com
第一次链接会出现提示Are you sure you want to continue connecting (yes/no)? 输入yes回车。 提示下面的就代表成功了！ Hi riceFun! You've successfully authenticated, but GitHub does not provide shell access.
