把你的本地主机用户的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test1,远程主机test2
一，在test1主机里的用户
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
Generating RSA keys:
Key generation complete.
会在用户目录~/.ssh/产生两个文件，id_rsa，id_rsa.pub
二，把id_rsa.pub文件拷贝到test2主机的用户目录下
cat id_rsa.pub >~/.ssh/authorized_keys
就可以了
这样test1主机的用户就可以通过ssh而不用密码登陆test2主机
