Mac 上配置 SSH - 多个 SSH

进入 ssh 目录，查看目录

cd ~/.ssh
ls

ls 命令效果

config            id_rsa.pub        id_rsa_github.pub known_hosts.old
id_rsa            id_rsa_github     known_hosts

生成对称加密秘钥，默认名称 id_rsa

ssh-keygen -t rsa -C "youremail@yourcompany.com"

指定秘钥名称 id_rsa_github，名字任意定

ssh-keygen -t rsa -C "youremail@yourcompany.com" -f ~/.ssh/id_rsa_github

配置 config 文件

vim config

# gitlab rsa pub
# Host相当于别名，随便取，使用的时候注意名称一致，git clone git@NBGit:anzhiyu-c/anzhiyu-c.git
Host NBGit
    # HostName：域名
    HostName github.com
    # 账号，不配置User也可生效
    User anzhiyu-c@qq.com
    # 权限
    PreferredAuthentications publickey
    # 对应域名下的秘钥
    IdentityFile ~/.ssh/id_rsa_github

# gitlab rsa pub
Host gitlab
    HostName gitlab.com
    User anzhiyu_c@163.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa

测试

ssh -T git@NBGit
Hi anzhiyu-c! You've successfully authenticated, but GitHub does not provide shell access.
