一、把本地主机用户的ssh公匙文件写入到远程主机用户的~/.ssh/authorized_keys文件中,具体方法:假设本地主机localhost,远程主机remote的用户
运行 ssh-keygen -t rsa
结果如下
Generating public/private rsa key pair.
Enter file in which to save the key (/home/.username/ssh/id_rsa):#回车
Enter passphrase (empty for no passphrase):#回车
Enter same passphrase again:#回车
Your identification has been saved in /home/.username /.ssh/id_rsa.
Your public key has been saved in /home/.username /.ssh/id_rsa.pub.
The key fingerprint is:
38:25:c1:4d:5d:d3:89:bb:46:67:bf:52:af:c3:17:0c username@localhost

Key generation complete.
会在用户目录~/.ssh/产生两个文件,id_rsa,id_rsa.pub 继续阅读
