生成ssh密钥,将公钥上传至远程服务器~/.ssh目录下面(没有的话就建一个):

ssh-keygen -t rsa
scp ~/.ssh/id_rsa.pub root@yourserver.com:/root/.ssh/

登录到远程服务器,导入公钥到authorized_keys(没有建一个):

cd ~/.ssh
cat id_rsa.pub >> authorized_keys

删除公钥

rm id_rsa.pub

 本地配置ssh config

Host server1
HostName 1.2.3.4
Port 22722
User root
IdentityFile ~/.ssh/id_rsa

Host server2
HostName 2.3.4.5
User root

这样就可以ssh server1,ssh server2登录远程服务器了。
