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。
