要建立用户等效性，请在两个节点上以 grid 用户身份生成用户的公钥和私钥。注意：要检查/home/grid 目录。一定要是 700(rwx 对应权限 421)第一步：在 node1 上执行 #su - gridnode1 - mkdir /.sshnode1 - chmod 700 /.sshnode1 - ssh-keygen -t rsaGenerating public/private rsa key pair.Enter file in which to save the key (/export/home/onodele/.ssh/id_rsa):Enter passphrase (empty for no passphrase):Enter same passphrase again:Your identification has been saved in /export/home/onodele/.ssh/id_rsa.Your public key has been saved in /export/home/onodele/.ssh/id_rsa.pub.The key fingerprint is:d3:ae:55:e0:eb:72:d9:1b:33:7a:ba:3c:55:3c:15:fe root node1 node1 - ssh-keygen -t dsaGenerating public/private dsa key pair.Enter file in which to save the key (/export/home/onodele/.ssh/id_dsa):Enter passphrase (empty for no passphrase):Enter same passphrase again:Your identification has been saved in /export/home/onodele/.ssh/id_dsa.Your public key has been saved in /export/home/onodele/.ssh/id_dsa.pub.The key fingerprint is:fd:1b:14:f6:8d:20:aa:a3:4f:87:1a:9f:97:3d:5b:47 root node1 第二步：在 node2 上执行上面同样的操作第三步：在 node1 上执行 node1 - cat /.ssh/id_rsa.pub /.ssh/authorized_keysnode1 - cat /.ssh/id_dsa.pub /.ssh/authorized_keysnode1 - ssh node2 cat /.ssh/id_rsa.pub /.ssh/authorized_keysThe authenticity of host node2 (192.168.2.132) cant be established.RSA key fingerprint is 63:d3:52:d4:4d:e2:cb:ac:8d:4a:66:9f:f1:ab:28:1f.Are you sure you want to continue connenodeng (yes/no)? yesWarning: Permanently added node1,198.93.1.10 (RSA) to the list of known hosts.onodelenode2s password:node1 - ssh node2 cat /.ssh/id_dsa.pub /.ssh/authorized_keysonodelenode2s password:node1 - scp /.ssh/authorized_keys node2:/.ssh/authorized_keysonodelenode2s password:authorized_keys 100% 1716 1.7KB/s 00:00执行上面三步后，在每个节点上测试连接。验证当您再次运行以下命令时，系统是否不提示您输入口令。 在 node1 上执行：ssh node2 datessh node2-priv date在 node2 上执行：ssh node1 datessh node1-priv date在测试的时候，会有提示，输入 yes 即可，但是切记要在两个节点运行。如果有异常，需要检查原因，一般来说是 hosts 文件的问题。
