前言

分布式应用通常要发布到非常多的机器，需要保持每台一致性，减轻工作量。可使用scp命令。

ssh-keygen

ssh-keygen，直接回车，不用输入。

[webuser@pay-app-sever3 ~]$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/app/webuser/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /app/webuser/.ssh/id_rsa.
Your public key has been saved in /app/webuser/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:MaSY8MmHYA+vWQw7wZFz464hiG+W8V0HvlbtLKyUXbI webuser@pay-app-sever3
The key‘s randomart image is:
