系统环境:
操作系统:RedHat EL5
Cluster: Oracle CRS 10.2.0.1.0
Oracle: Oracle 10.2.0.1.0
如图所示:RAC 系统架构
6、通过SSH配置主机间的信任关系
node1:
[oracle@node1 ~]$ mkdir .ssh
[oracle@node1 ~]$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_rsa.
Your public key has been saved in /home/oracle/.ssh/id_rsa.pub.
The key fingerprint is:
fa:82:c7:18:88:6f:f0:c8:a4:cf:2e:69:a3:f8:36:ad oracle@rac1
[oracle@node1 ~]$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_dsa.
Your public key has been saved in /home/oracle/.ssh/id_dsa.pub.
The key fingerprint is:
3c:81:49:df:a0:c6:12:7c:2a:ae:d1:48:f2:5b:37:78 oracle@rac1
node2:
[root@node2 asm]# su - oracle
[oracle@node2 ~]$ mkdir .ssh
[oracle@node2 ~]$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_rsa.
Your public key has been saved in /home/oracle/.ssh/id_rsa.pub.
The key fingerprint is:
5b:6b:f5:61:54:0c:5a:8d:b5:14:b3:35:91:2e:0b:31 oracle@rac2
[oracle@node2 ~]$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_dsa): Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_dsa.
Your public key has been saved in /home/oracle/.ssh/id_dsa.pub.
The key fingerprint is:
5f:82:67:d0:4a:da:e7:8b:43:1a:cf:41:dc:8e:9b:c1 oracle@rac2
node1:
[oracle@node1 ~]$ cat .ssh/id_rsa.pub >> .ssh/authorized_keys
[oracle@node1 ~]$ cat .ssh/id_dsa.pub >> .ssh/authorized_key s
[oracle@node1 ~]$ ssh node2 cat .ssh/id_rsa.pub >> .ssh/authorized_keys
The authenticity of host ‘node2 (192.168.8.11)‘ can‘t be established.
RSA key fingerprint is 1c:b2:66:d8:fc:a9:29:45:73:dd:ca:92:ca:b8:0a:20.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘node2,192.168.8.11‘ (RSA) to the list of known hosts.
oracle@node2‘s password:
[oracle@node1 ~]$ ssh node2 cat .ssh/id_dsa.pub >>.ssh/authorized_keys
oracle@node2‘s password:
[oracle@node1 ~]$ scp .ssh/authorized_keys node2:~/.ssh
oracle@node2‘s password:
authorized_keys 100%
在两个节点上测试信任关系:
[oracle@node1 ~]$ ssh node2 date
Mon Sep 3 07:47:14 CST 2012
[oracle@node1 ~]$ ssh node2-priv date
The authenticity of host ‘node2-priv (10.10.10.2)‘ can‘t be established.
RSA key fingerprint is 1c:b2:66:d8:fc:a9:29:45:73:dd:ca:92:ca:b8:0a:20.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘node2-priv,10.10.10.2‘ (RSA) to the list of known hosts.
Mon Sep 3 07:47:37 CST 2012
[oracle@node1 ~]$ ssh node1-priv date
Mon Sep 3 07:47:42 CST 2012
[oracle@node1 ~]$ ssh node1 date
The authenticity of host ‘node1 (192.168.8.10)‘ can‘t be established.
RSA key fingerprint is 6d:1d:6b:1a:34:63:f2:f4:4c:15:0d:eb:60:e0:13:4d.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘node1,192.168.8.10‘ (RSA) to the list of known hosts.
Mon Sep 3 07:48:57 CST 2012
node2:
[oracle@node2 ~]$ ssh node1 date
Mon Sep 3 07:48:58 CST 2012
[oracle@node2 ~]$ ssh node1-priv date
The authenticity of host ‘node1-priv (10.10.10.1)‘ can‘t be established.
RSA key fingerprint is 6d:1d:6b:1a:34:63:f2:f4:4c:15:0d:eb:60:e0:13:4d.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘node1-priv,10.10.10.1‘ (RSA) to the list of known hosts.
Mon Sep 3 07:49:08 CST 2012
[oracle@node2 ~]$ ssh node2-priv date
Mon Sep 3 07:49:09 CST 2012
[oracle@node2 ~]$ ssh node2 date
Mon Sep 3 07:49:09 CST 2012
注意:一定保证通过ssh连接时不需要输入任何东东
7、配置Oracle ASM
在Linux 需要安装ASM软件 (注意要和内核匹配,在所有节点)
所需的软件包:
[root@rac1 ASM]# ls -l
total 236
-rwxr--r-- 1 oracle oinstall 129340 Sep 3 2012 oracleasm-2.6.9-67.ELsmp-2.0.3-1.i686.rpm
-rwxr--r-- 1 oracle oinstall 13105 Sep 3 2012 oracleasmlib-2.0.4-1.el4.i386.rpm
-rwxr--r-- 1 oracle oinstall 83255 Sep 3 2012 oracleasm-support-2.1.4-1.el4.i386.rpm
linux 内核版本:
[root@rac1 ASM]# uname -a
Linux rac1 2.6.9-67.ELsmp #1 SMP Wed Nov 7 13:58:04 EST 2007 i686 i686 i386 GNU/Linux
安装:
[root@rac1 ASM]# rpm -ivh *
warning: oracleasmlib-2.0.4-1.el4.i386.rpm: V3 DSA signature: NOKEY, key ID b38a8516
Preparing... ########################################### [100%]
1:oracleasm-support ########################################### [ 33%]
2:oracleasm-2.6.9-67.ELsm########################################### [ 67%]
3:oracleasmlib ########################################### [100%]
配置Oracle ASM:
[root@rac1 ASM]# service oracleasm configure
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets (‘[]‘). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]:
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLib disks: [ OK ]
[root@rac1 ASM]#
@至此Oracle 10g RAC安装和配置前的准备工作准备就绪
