二、RAC 安装前期配置
1、配置/etc/host文件（rac1、rac2上执行）
127.0.0.1 localhost
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
#rac1
192.168.100.11 rac1
192.168.100.13 rac1-vip
192.168.10.11 rac1-priv
#rac2
192.168.100.12 rac2
192.168.100.14 rac2-vip
192.168.10.12 rac2-priv
#scan-ip
192.168.100.10 scan-cluster
2、配置DNS服务器，解析scan ip（rhel5.8上执行）
1）安装dns包
[root@localhost mnt]# ll
total 1112
-rw-r--r-- 1 root root 1012559 Jan 22 11:11 bind-9.3.6-20.P1.el5.x86_64.rpm
-rw-r--r-- 1 root root 47941 Jan 22 11:14 bind-chroot-9.3.6-20.P1.el5.x86_64.rpm
-rw-r--r-- 1 root root 64667 Jan 22 11:11 caching-nameserver-9.3.6-20.P1.el5.x86_64.rpm
[root@localhost mnt]# rpm -ivh bind-9.3.6-20.P1.el5.x86_64.rpm
[root@localhost mnt]# rpm -ivh bind-chroot-9.3.6-20.P1.el5.x86_64.rpm
[root@localhost mnt]# rpm -ivh caching-nameserver-9.3.6-20.P1.el5.x86_64.rpm
2）配置named.conf文件
生成named.conf文件：
[root@localhost mnt]# cd /var/named/chroot/etc/
[root@localhost etc]# ll
total 24
-rw-r--r-- 1 root root 3519 Feb 27 2006 localtime
-rw-r----- 1 root named 1230 Dec 2 2011 named.caching-nameserver.conf
-rw-r----- 1 root named 955 Dec 2 2011 named.rfc1912.zones
-rw-r----- 1 root named 113 Jan 22 10:51 rndc.key
[root@localhost etc]# cp -p named.caching-nameserver.conf named.conf
[root@localhost etc]# ll
total 28
-rw-r--r-- 1 root root 3519 Feb 27 2006 localtime
-rw-r----- 1 root named 1230 Dec 2 2011 named.caching-nameserver.conf
-rw-r----- 1 root named 1230 Dec 2 2011 named.conf
-rw-r----- 1 root named 955 Dec 2 2011 named.rfc1912.zones
-rw-r----- 1 root named 113 Jan 22 10:51 rndc.key
配置named.conf文件：
[root@localhost etc]# vim named.conf
将127.0.0.1和localhost全部改成any。
3）配置named.rfc1912.zones文件
[root@localhost etc]# vim named.rfc1912.zones --在最后添加下面内容
zone "100.168.192.in-addr.arpa" IN {
type master;
file "100.168.192.in-addr.arpa";
allow-update { none; };
};
4）生成正反向解析数据库文件
[root@localhost named]# pwd
/var/named/chroot/var/named
[root@localhost named]# ll
total 44
drwxrwx--- 2 named named 4096 Aug 26 2004 data
-rw-r----- 1 root named 198 Dec 2 2011 localdomain.zone
-rw-r----- 1 root named 195 Dec 2 2011 localhost.zone
-rw-r----- 1 root named 427 Dec 2 2011 named.broadcast
-rw-r----- 1 root named 1892 Dec 2 2011 named.ca
-rw-r----- 1 root named 424 Dec 2 2011 named.ip6.local
-rw-r----- 1 root named 426 Dec 2 2011 named.local
-rw-r----- 1 root named 427 Dec 2 2011 named.zero
drwxrwx--- 2 named named 4096 Jul 27 2004 slaves
[root@localhost named]# cp -p named.local 100.168.192.in-addr.arpa
[root@localhost named]# ll
total 48
-rw-r----- 1 root named 426 Dec 2 2011 100.168.192.in-addr.arpa
drwxrwx--- 2 named named 4096 Aug 26 2004 data
-rw-r----- 1 root named 198 Dec 2 2011 localdomain.zone
-rw-r----- 1 root named 195 Dec 2 2011 localhost.zone
-rw-r----- 1 root named 427 Dec 2 2011 named.broadcast
-rw-r----- 1 root named 1892 Dec 2 2011 named.ca
-rw-r----- 1 root named 424 Dec 2 2011 named.ip6.local
-rw-r----- 1 root named 426 Dec 2 2011 named.local
-rw-r----- 1 root named 427 Dec 2 2011 named.zero
drwxrwx--- 2 named named 4096 Jul 27 2004 slaves
5）配置正向解析数剧库文件
[root@localhost named]# vim localdomain.zone
[root@localhost named]# cat localdomain.zone
$TTL 86400
@ IN SOA localhost root (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS localhost
localhost IN A 127.0.0.1
scan-cluster IN A 192.168.100.10
6）配置反向解析数据库文件
[root@localhost named]# vim 100.168.192.in-addr.arpa
[root@localhost named]# cat 100.168.192.in-addr.arpa
$TTL 86400
@ IN SOA localhost. root.localhost. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS localhost.
1 IN PTR localhost.
10 IN PTR scan-cluster.localdomain
7）服务器上启动DNS服务器
[root@localhost named]# /etc/init.d/named status
rndc: connect failed: 127.0.0.1#953: connection refused
named is stopped
[root@localhost named]# /etc/init.d/named start
Starting named: [ OK ]
8）配置/etc/resolv.conf文件（rac1、rac2上执行）
[root@rac1 ~]# vim /etc/resolv.conf
[root@rac1 ~]# cat /etc/resolv.conf
# Generated by NetworkManager
search localdomain
# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com
nameserver 192.168.100.9
9）nslookup检查（rac1、rac2上检验）
[root@rac1 ~]# nslookup 192.168.100.10
Server: 192.168.100.9
Address: 192.168.100.9#53
10.100.168.192.in-addr.arpa name = scan-cluster.localdomain
[root@rac1 ~]# nslookup scan-cluster
Server: 192.168.100.9
Address: 192.168.100.9#53
Name: scan-cluster.localdomain
Address: 192.168.100.10
3、建组、用户、环境变量、内核参数等（rac1、rac2上执行）

6、配置共享磁盘
1）创建6块共享磁盘并fdisk格式化。
2）安装asm rpm包：
[root@rac2 ~]# cd /mnt
[root@rac2 mnt]# ll
total 136
-rw-r--r--. 1 root root 33956 Jan 22 17:23 kmod-oracleasm-2.0.6.rh1-3.el6.x86_64.rpm
-rw-r--r--. 1 root root 13300 Jan 22 17:23 oracleasmlib-2.0.4-1.el6.x86_64.rpm
-rw-r--r--. 1 root root 74984 Jan 22 17:23 oracleasm-support-2.1.8-1.el6.x86_64.rpm
[root@rac2 mnt]# rpm -qa|grep oracleasm
[root@rac2 mnt]# rpm -ivh kmod-oracleasm-2.0.6.rh1-3.el6.x86_64.rpm
Preparing... ########################################### [100%]

kmod-oracleasm-2.0.6.rh1-3.el6.x86_64
oracleasmlib-2.0.4-1.el6.x86_64
3）双节点配置asm driver服务
[root@rac1 mnt]# /usr/sbin/oracleasm -h
Usage: oracleasm [--exec-path=<exec_path>] <command> [ <args> ]
oracleasm --exec-path
oracleasm -h
oracleasm -V
The basic oracleasm commands are:
configure Configure the Oracle Linux ASMLib driver
init Load and initialize the ASMLib driver
exit Stop the ASMLib driver
scandisks Scan the system for Oracle ASMLib disks
status Display the status of the Oracle ASMLib driver
listdisks List known Oracle ASMLib disks
querydisk Determine if a disk belongs to Oracle ASMlib
createdisk Allocate a device for Oracle ASMLib use
deletedisk Return a device to the operating system
renamedisk Change the label of an Oracle ASMlib disk
update-driver Download the latest ASMLib driver
[root@rac1 mnt]# /usr/sbin/oracleasm status
Checking if ASM is loaded: no
Checking if /dev/oracleasm is mounted: no
[root@rac1 mnt]# /usr/sbin/oracleasm configure -i
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 []: grid
Default group to own the driver interface []: asmadmin
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: done
[root@rac1 mnt]# /usr/sbin/oracleasm status
Checking if ASM is loaded: no
Checking if /dev/oracleasm is mounted: no
[root@rac1 mnt]# /usr/sbin/oracleasm init

Loading module "oracleasm": oracleasm
Mounting ASMlib driver filesystem: /dev/oracleasm
[root@rac1 mnt]# /usr/sbin/oracleasm status
Checking if ASM is loaded: yes
Checking if /dev/oracleasm is mounted: yes
4）配置asm磁盘
节点1：
[root@rac1 mnt]# /usr/sbin/oracleasm -h
Usage: oracleasm [--exec-path=<exec_path>] <command> [ <args> ]
oracleasm --exec-path
oracleasm -h
oracleasm -V
The basic oracleasm commands are:
configure Configure the Oracle Linux ASMLib driver
init Load and initialize the ASMLib driver
exit Stop the ASMLib driver
scandisks Scan the system for Oracle ASMLib disks
status Display the status of the Oracle ASMLib driver
listdisks List known Oracle ASMLib disks
querydisk Determine if a disk belongs to Oracle ASMlib
createdisk Allocate a device for Oracle ASMLib use
deletedisk Return a device to the operating system
renamedisk Change the label of an Oracle ASMlib disk

7、安装grid软件
1）上传安装介质，解压（一个节点即可）。
2）安装grid前预检查（一个节点即可）
[grid@rac1 grid]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose
3）图形界面安装grid软件
以下图形界面安装略。
