回答by Xu Ding
ssh-keygen # generate a pair of RSA keys
scp ~/.ssh/id_rsa.pub [email protected]:id_rsa.tmp # copy the public key to remote host
ssh [email protected] # ssh to remote server, this time it requires password
cat id_rsa.tmp >> .ssh/authorized_keys # add the public key to authorized_keys
Then you could log off and log on without passwords.
然后，您可以注销并在没有密码的情况下登录。

Under shell script you may need to disable host key checking:

I have looked in to this extensively, and this is why I decided to learn python. The short answer is "No". There is no way with standard bash to pass a password to ssh prompt. There are some things you can install like expect or sshpass which can give you this functionality, but using those depends on if you have free roam on the server you are running the script. If you have ever wanted to learn python, this is a good one to learn on. There is a python module called "Fabric" which has this functionality built in, and is easy to use.
我已经对此进行了广泛的研究，这就是我决定学习 Python 的原因。最简洁的答案是不”。标准 bash 无法将密码传递给 ssh 提示符。您可以安装一些东西，例如 expect 或 sshpass，它们可以为您提供此功能，但是使用这些取决于您在运行脚本的服务器上是否可以自由漫游。如果你曾经想学习 Python，这是一个很好的学习方法。有一个名为“Fabric”的 Python 模块，它内置了此功能，并且易于使用。
Sorry this isn't a real answer, just thought I would pass on my advice, since I have been exactly where you are....
对不起，这不是一个真正的答案，只是想我会传递我的建议，因为我一直在你所在的地方......

Expect is the tool of choice for any situation where you want to automate man-machine interaction.
对于您想要自动化人机交互的任何情况，Expect 都是首选工具。
Check it out... it is very easy to learn (at least for simple tasks like the one you need to tackle), and it is not uncommon to find it already installed in many a server.
检查一下……它很容易学习（至少对于像您需要处理的任务这样的简单任务），并且发现它已经安装在许多服务器中的情况并不少见。
Just thought I would pass on my view on this... good luck!
只是想我会传递我对此的看法......祝你好运！
