一、准备ssh-copy-id 服务器
brew install ssh-copy-id ssh
二、生成私钥公钥 spa
ssh-keygen -t rsa -b 1024 it
三、将公钥上传致服务器(~/.ssh/authorized_keys) io
ssh-copy-id -i 公钥 root@192.168.1.xxx email
四、在本地~/.config文件中添加(若是没有则新建) rsa
Host xxx
HostName 192.168.1.xxx
User root
PreferredAuthentications publickey
IdentityFile ~/.ssh/私钥 im
ssh-keygen -t dsa –C user.email –f ~/.ssh/user.email ssh-key
