1、生成ssh-key

$ ssh-keygen -t rsa -C “hedx@gmail.com”

一路回车

2、查看

$ cd ~/.ssh$ ls

发现存在id_rsa和id_rsa.pub文件

3、复制id_rsa.pub文件

$ vi id_rsa.pub

将内容复制到git的ssh中，或者其他要用到的地方。

4、添加可访问的计算机

vi ~/.ssh/authorized_keys

将目的计算机的id_rsa.pub内容复制，粘贴到authorized_keys文件中。

5、客户机访问遇到问题

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:heVOpBzvcxKzicKWZW5qdO5N/Bahtww4cTrjs2gSf9c.
Please contact your system administrator.
Add correct host key in /home/user/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /home/user/.ssh/known_hosts:7
remove with:
ssh-keygen -f “/home/user/.ssh/known_hosts” -R 192.168.1.1
ECDSA host key for 192.168.1.1 has changed and you have requested strict checking.

执行

ssh-keygen -R 192.168.1.1

ssh会把你每个你访问过计算机的公钥都记录在~/.ssh/known_hosts。当下次访问相同计算机时，ssh会核对公钥。
