linux下Oracle11g RAC搭建（五）

linux下Oracle11g RAC搭建（五）

四、建立主機間的信任關係（node1、node2）

 

建立節點之間oracle 、grid 使用者之間的信任（通過ssh 建立公開金鑰和私密金鑰）

分別在node1和node2建立

=====Oracle使用者=========================

在oracle使用者下操作：

[root@node1 /]# su - oracle

[oracle@node1 ~]$ mkdir .ssh       建立一個.ssh的隱藏目錄

[oracle@node1 ~]$ ls -al

total 44

-rw-r--r-- 1 oracle oinstall   33 Jul 12 17:05 .bash_logout

-rw-r--r-- 1 oracle oinstall  438 Jul 12 18:03 .bash_profile

drwxr-xr-x 4 oracle oinstall 4096 Jul 1217:05 .mozilla

drwx------ 2 oracle oinstall 4096 Jul 1218:05 .ssh

-rw------- 1 oracle oinstall  657 Jul 12 18:03 .viminfo

 

1）產生金鑰組（rsa+dsa）（node1、node2） node1產生密鑰rsa類型

id_rsa為私密金鑰，自動儲存到.ssh下

id_rsa.pub為公開金鑰，自動儲存到.ssh下

 

[oracle@node1 ~]$ ssh-keygen -t rsa

Your public key has been saved in/home/oracle/.ssh/id_dsa.pub.                

The key fingerprint is:

7c:41:b5:0f:81:06:ad:30:07:4f:8b:1a:9b:94:68:14oracle@node1

node2產生密鑰rsa類型

Your public key has been saved in/home/oracle/.ssh/id_rsa.pub.           

The key fingerprint is:

64:a6:4a:77:db:33:a4:aa:6e:ca:8f:5f:2f:77:0f:40oracle@node1

node2產生密鑰dsa類型

The keyfingerprint is:

7c:41:b5:0f:81:06:ad:30:07:4f:8b:1a:9b:94:68:14oracle@node1

 

2）配置信任關係（node1、node2）為node1配置信任

[oracle@node1 ~]$ ls .ssh

 

id_dsa       id_rsa             id_dsa.pub   id_rsa.pub     

//rsa和dsa為私密金鑰                .pub的為公開金鑰 

//ssh下檔案authorized_keys是專門儲存公開金鑰資訊的

//把rsa、dsa類型的公開金鑰檔案都放入到authorized_keys檔案裡

// “ssh  node2”命令代表登陸到節點2下操作

//把兩種類型的公開金鑰資訊都放到節點2的authorized_keys檔案裡

 

[oracle@node1 ~]$ cat.ssh/id_rsa.pub >>.ssh/authorized_keys

[oracle@node1 ~]$ cat.ssh/id_dsa.pub >>.ssh/authorized_keys

[oracle@node1 ~]$ ssh node2  cat .ssh/id_rsa.pub>>.ssh/authorized_keys

oracle@node2's password:

[oracle@node1 ~]$ ssh node2  cat .ssh/id_dsa.pub>>.ssh/authorized_keys

oracle@node2's password:  oracle的密碼

為node2配置信任

可以把node1中的authorized_keys（密鑰檔案）複製到node2中

[oracle@node1 ~]$ scp.ssh/authorized_keys   node2:~/.ssh

oracle@node2's password: oracle的密碼

3）驗證信任關係（node1、node2）node1上驗證信任

[oracle@node1 ~]$ ssh node2date

[oracle@node1 ~]$ ssh node2-privdate     //私人ip地址驗證

[oracle@node1 ~]$ ssh node1date

[oracle@node1 ~]$ ssh node1-privdate    

 

詳細操作如下：

[oracle@node1 ~]$ ssh node2date

Thu May  214:46:30 CST 2013

[oracle@node1 ~]$ sshnode2-priv date                 //不要求輸入密碼代表信任成功

The authenticity of host 'node2-priv (10.10.10.2)'can't be established.

RSA key fingerprint is16:28:88:50:27:30:92:cb:49:be:55:61:f6:c2:a1:3f.

Are you sure you want to continue connecting (yes/no)? yes
