ssh key generate

Apps-iMac:.ssh pengjianqing$ ssh-keygen -t rsa -C "[email protected]"

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/pengjianqing/.ssh/id_rsa): digitalocean_rsa
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in digitalocean_rsa.
Your public key has been saved in digitalocean_rsa.pub.
The key fingerprint is:
ec:aa:66:48:07:e0:91:53:73:2b:e9:14:c0:f6:ca:d5 [email protected]
The key's randomart image is:
+--[ RSA 2048]----+
|..++ .           |
|.*  = .          |
|o.++..           |
| .+o.E .         |

Then get the pub key

cat digitalocean_rsa.pub

Add it to the server side

[email protected]:~# vim ~/.ssh/authorized_keys

multiple ssh keys

Sometimes we will have many different ssh keys, so need config it to support different keys.

touch ~/.ssh/config

Apps-iMac:.ssh pengjianqing$ cat config

Host ef.pjq.me
    IdentityFile ~/.ssh/digitalocean_rsa
    User root

so finally the config will be like this

Host ef.pjq.me
    IdentityFile ~/.ssh/digitalocean_rsa
    User root

Host aliyun.pjq.me
    IdentityFile ~/.ssh/aliyun_rsa
    User root

Host vps.pjq.me
    IdentityFile ~/.ssh/yardvps_rsa
    User root
