先到远程服务器的 ~/.ssh 目录下面新建文件 “authorized_keys”，然后再将本地主机的ssh Key复制到远程服务器上的authorized_keys文件中，一行一个sshKey，远程服务器也要生成一下sshkey

看一下/etc/sshd/sshd_config / /etc/ssh/sshd_config，修改PasswordAuthentication yes

问问题别贴那么长的东西，拣主要的说就好了，你贴那么多谁有时间看呢 a机免密码登录b机： 1. a机运行 ssh-keygen -t rsa -P ''，生成的 id_rsa.pub拷到 b机 .ssh/ 2. b机运行 cat .ssh/id_rsa.pub >> .ssh/authorized_keys 3. b机运行 chmod 600 .ssh/authorized_keys
