2.9.配置使用者等效性(可選項)

　　Oracle 11g r2 ssh也可以在安裝過程中配置.

2.9.1. grid使用者等效性

1.以下均以grid使用者執行: 在兩個節點的grid主目錄分別建立.ssh目錄，並賦予許可權

linuxrac1 [[email protected] ~]$mkdir ~/.ssh [[email protected] ~]$chmod 755 ~/.ssh [[email protected] ~]$ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/home/grid/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/grid/.ssh/id_rsa. Your public key has been saved in /home/grid/.ssh/id_rsa.pub. The key fingerprint is: 7a:7b:62:31:da:07:88:0d:22:46:46:28:d1:cc:87:e1 [email protected] [[email protected] ~]$ssh-keygen -t dsa Generating public/private dsa key pair. Enter file in which to save the key (/home/grid/.ssh/id_dsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/grid/.ssh/id_dsa. Your public key has been saved in /home/grid/.ssh/id_dsa.pub.

Enter file in which to save the key (/home/grid/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/grid/.ssh/id_rsa. Your public key has been saved in /home/grid/.ssh/id_rsa.pub. The key fingerprint is: 69:8c:94:2b:2b:a4:8d:33:82:8f:b0:49:03:a1:1a:b9 [email protected]   [[email protected] ~]$ ssh-keygen -t dsa Generating public/private dsa key pair.

The key fingerprint is: 1f:4d:e7:3f:c7:4d:d8:f0:55:f0:eb:c1:ea:74:93:24 [email protected]   以上用預設配置,一路斷行符號即可   linuxrac1 cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys ssh [email protected] cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys 或 ssh [email protected] cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys ssh [email protected] cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys [email protected] ~]$ cd .ssh [[email protected] .ssh]$ ll total 48 -rw-r--r-- 1 grid oinstall 2000 Sep 25 00:48 authorized_keys -rw------- 1 grid oinstall  668 Sep 25 00:43 id_dsa -rw-r--r-- 1 grid oinstall  604 Sep 25 00:43 id_dsa.pub -rw------- 1 grid oinstall 1675 Sep 25 00:42 id_rsa -rw-r--r-- 1 grid oinstall  396 Sep 25 00:42 id_rsa.pub -rw-r--r-- 1 grid oinstall  404 Sep 25 00:48 known_hosts   linuxrac2 cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys ssh [email protected] cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys 或 ssh [email protected] cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys ssh [email protected] cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

2.建立等效性 rac1,rac2雙節點執行

• The authenticity of host ‘<host>‘ can‘t be established.  

 

　　解決辦法：在串連目標機上執行ssh  -o StrictHostKeyChecking=no  xxxx(機器名)
