客服端配置

生成密鑰

$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/TOYOTA/.ssh/id_rsa): id_rsa_1024
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in id_rsa_1024.
Your public key has been saved in id_rsa_1024.pub.
The key fingerprint is:
SHA256:mlWG1odeg3evLHgP4vPnjjYJCCBONY/DATi2ZelrxPI TOYOTA@DESKTOP-O7FUOAH
The key's randomart image is:
+---[RSA 2048]----+
| ..o=            |
|o.o=.=   o o     |
|.+*.+.. o * = .  |
| o.+ ... + + o . |
|  + .  .S..     .|
|   E   +. .. . . |
|  .   o   o.+.o  |
|         ..o+=.  |
|          .+o=+  |
+----[SHA256]-----+

配置服務器

拷貝公鑰到遠程服務器上，或則其他地方

scp ~/.ssh/id_rsa_1024.pub [e-mail]:~/.ssh/

然後登錄服務器後，將剛生成的公鑰追加到~/.ssh/authorized_keys文件中

ssh [e-mail]
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys 

編輯客服端ssh配置文件

編輯~/.ssh/config文件，如果文件不存在則新建

#One
Host aliasName1
HostName 192.168.1.161
User root
IdentityFile ~/.ssh/id_rsa_1024

#Two
Host aliasName2
HostName 192.168.1.162
User root
Port 2233

#後面跟着的是註釋
Host 別名
HostName 服務器地址也可以是域名(如：www.xxx.com)
User 用戶名
Port 端口號 可省略 默認爲22
IdentityFile 私鑰地址 可省略 默認爲~/.ssh/id_rsa
