使用下例中ssky-keygen和ssh-copy-id，仅需通过3个步骤的简单设置而无需输入密码就能登录远程linux主机。 ssh-keygen 创建公钥和密钥。 ssh-copy-id 把本地主机的公钥复制到远程主机的authorized_keys文件上。 ssh-copy-id 也会给远程主机的用户主目录（home）和~/.ssh, 和~/.ssh/authorized_keys设置合适的权限 。 步骤1: 用 ssh-key-gen 在本地主机上创建公钥和密钥 ligh@local-host$ ssh-keygen -t rsa enter file in which to save the key (/home/jsmith/.ssh/id_rsa):[enter key] enter passphrase (empty for no passphrase): [press enter key] enter same passphrase again: [pess enter key] your identification has been saved in /home/jsmith/.ssh/id_rsa. your public key has been saved in /home/jsmith/.ssh/id_rsa.pub. the key fingerprint is: 33:b3:fe:af:95:95:18:11:31:d5:de:96:2f:f2:35:f9 ligh@local-host 步骤2: 用 ssh-copy-id 把公钥复制到远程主机上 ligh@local-host$ ssh-copy-id -i ~/.ssh/id_rsa.pub root@192.168.0.3 ligh@remote-host‘s password: now try logging into the machine, with ―ssh ?remote-host‘‖, and check in: .ssh/authorized_keys to make sure we haven‘t added extra keys that you weren‘t expecting. [注: ssh-copy-id 把密钥追加到远程主机的 .ssh/authorized_key 上.] 步骤3: 直接登录远程主机 ligh@local-host$ ssh remote-host last login: sun nov 16 17:22:33 2008 from 192.168.1.2 [注: ssh 不会询问密码.] ligh@remote-host$ [注: 你现在已经登录到了远程主机上
