请教ssh自动登陆

lee_vs

每次远程登陆服务器的时候，都要先ssh user@10.3.3.3然后，输入用户和长长的密码。
觉得很麻烦。想写一个脚本，自动用该脚本里面的用户和密码登陆。
在此请教了

不用这么麻烦啦，设置无密码的ssh登陆就可以了。
man 一下ssh, 搜索 without giving the password.

If u r using ssh version 2, run ssh-keygen -t rsa on local machine, it will generate two files id_rsa and id_rsa.pub in your $HOME/.ssh folder by default.
It will also ask u to input the passphase, the default is empty.
On the remote side, copy the content of id_rsa.pub into $HOME/.ssh/authorized_keys2
Then u can just write an easy shell script to connect. When u run this shell script no password would be asked.
