要想在linux上从一台机器ssh到另一台机器，�q�且不用密码的办法，需要配�|�两机间的信��d��p�，步骤如下�Q?br />
�W�一步：生成密匙寏V�?
使用命��o
ssh-keygen -t rsa
对于屏幕提示�Q�只需要不断的回�R卛_��?
执行的结果：
�?HOME/.ssh/目录下生成了id_rsa和id_rsa.pub两个文�g
�W�二步：��公钥放到远�E�服务器上�?

id_rsa存放的是�U�钥�Q�保存在用户机器上，不需要�Q何操�?
id_rsa.pub存放的是公钥�Q�需��其内容��d��到远�E�服务器�?HOME/.ssh/authorized_keys文�g中�?
操作命��o�Q?
cat ~/.ssh/id_rsa.pub | ssh usrname@w.x.y.z 'cat >> ~/.ssh/authorized_keys'
ok�Q�以后��用ssh,scp以及sftp便不再要求键入密码了
