Question

linux scp怎么无秘钥传输

Answer 1

1. 在服务器 S 上执行如下命令来生成配对密钥：
ssh-keygen -t rsa
按照提示操作，注意，不要输入passphrase，因为我的之前已经操作过，所以还提示了是否覆盖，输入 "y"回车就可以。其他提示信息如下
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
