ssh远程连接linux服务器

1 在mac上生成密钥对，默认生成位置是~/.ssh
ssh-keygen

2. 用scp上一步生成的公钥发送到服务器上，同时执行
   cat id_rsa.pub >> ~/.ssh/authorized_keys
3. 连接服务器
   3.1 直连
   ssh -i ~/.ssh/id_rsa user@yourservername
   3.2：修改~/.ssh/config

Host server_alias(你的服务器别名)
HostName test.com/192.168.1.1(域名或IP)
Port 22
User user
Identifier id_rsa

然后就可以ssh server_alias连接了
