1.3.2、配置zone文件
# vi /etc/named.rfc1912.zones ##追加以下信息
zone "localdomain" IN {
type master;
file "forward.zone";
allow-update { none; };
};
zone "0.168.192.in-addr.arpa" IN {
type master;
file "reverse.zone";
allow-update { none; };
};
1.3.3、生成正向解析数据库文件
# cd /var/named/
# cp -p named.localhost forward.zone
# vi forward.zone ##正向解析数据库文件末尾加入如下
$TTL 1D
@ IN SOA node1.localdomain. root.localdomain. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
IN NS node1.localdomain.
node1 IN A 127.0.0.1
scan-cluster.localdomain IN A 192.168.0.8
scan-cluster IN A 192.168.0.8
~
1.3.4、生成方向解析数据库文件
# cp -p named.loopback reverse.zone
# vi reverse.zone ##反向解析数据库文件末尾加入如下
$TTL 1D
@ IN SOA node1.localdomain. root.localdomain. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
IN NS node1.localdomain.
3 IN PTR node1.localdomain.
8 IN PTR scan-cluster.localdomain.
8 IN PTR scan-cluster.
# service named restart
# vi /etc/resolv.conf ##文件末尾加入如下
search localdomain
nameserver 192.168.0.3
1.3、配置grid/oracle用户ssh对等性
##node1
node1->env |grep ORA
ORACLE_UNQNAME=devdb
ORACLE_SID=devdb1
ORACLE_BASE=/u01/app/oracle
ORACLE_HOSTNAME=node1.localdomain
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
##node2
node2->env |grep ORA
ORACLE_UNQNAME=devdb
ORACLE_SID=devdb2
ORACLE_BASE=/u01/app/oracle
ORACLE_HOSTNAME=node1.localdomain
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
在集群就绪服务 (CRS) 和 RAC 安装过程中，Oracle Universal Installer (OUI) 必须能够以 oracle 的身份将软件复制到所有 RAC 节点
而不提示输入口令
##node1

##验证oracle用户对等性
每个节点执行如下命令，第二次执行时不再需要输入口令
ssh node1 date
ssh node2 date
ssh node1-priv date
ssh node2-priv date
ssh node1.localdomain date
ssh node2.localdomain date
ssh node1-priv.localdomain date
ssh node2-priv.localdomain date
根据以上方法，grid用户配置对等性
1.5、安装rpm包，配置asm磁盘
1、格式化分区（两个节点任选其一）
2、安装asm包（每个节点）
# rpm -ivh kmod-oracleasm-2.0.6.rh1-3.el6.x86_64.rpm
# rpm -ivh oracleasm-support-2.1.8-1.el5.x86_64.rpm
# rpm -ivh oracleasmlib-2.0.4-1.el5.x86_64.rpm
# oracleasm configure -i
# oracleasm init
3、清理asm磁盘头
# dd if=/dev/zero of=/dev/sdb1 bs=8192 count=12800
12800+0 records in
12800+0 records out
104857600 bytes (105 MB) copied, 2.18097 s, 48.1 MB/s
# dd if=/dev/zero of=/dev/sdc1 bs=8192 count=12800
12800+0 records in
12800+0 records out
104857600 bytes (105 MB) copied, 1.29817 s, 80.8 MB/s
# dd if=/dev/zero of=/dev/sdd1 bs=8192 count=12800
12800+0 records in
12800+0 records out
104857600 bytes (105 MB) copied, 1.31786 s, 79.6 MB/s
# dd if=/dev/zero of=/dev/sde1 bs=8192 count=12800
12800+0 records in
12800+0 records out
104857600 bytes (105 MB) copied, 1.43146 s, 73.3 MB/s
# dd if=/dev/zero of=/dev/sdf1 bs=8192 count=12800
4、映射分区到asm磁盘（两个节点任选其一）
# oracleasm scandisks ##刷新asm磁盘信息，不然不是最新信息
# oracleasm createdisk VOL1 /dev/sdb1
Writing disk header: done
Instantiating disk: done
# oracleasm createdisk VOL2 /dev/sdc1
Writing disk header: done
Instantiating disk: done
# oracleasm createdisk VOL3 /dev/sdd1
Writing disk header: done
# oracleasm createdisk VOL4 /dev/sde1
Writing disk header: done
Instantiating disk: done
# oracleasm createdisk VOL5 /dev/sdf1
5、关闭NetworkManager
# chkconfig --level 123456 NetworkManager off
# service NetworkManager stop
Stopping NetworkManager daemon: [ OK ]
1.6、安装 cvuqdisk包，验证grid环境，并修复failed
1、安装cvuqdisk(每个节点)
# CVUQDISK_GRP=oinstall; export CVUQDISK_GRP
# rpm -qa |grep cvuqdisk
cvuqdisk-1.0.9-1.x86_64
# ll /home/grid/grid/rpm
total 12
-rwxr-xr-x 1 root root 8551 Sep 22 2011 cvuqdisk-1.0.9-1.rpm
# ls -l /usr/sbin/cvuqdisk
-rwsr-xr-x 1 root oinstall 10928 Sep 4 2011 /usr/sbin/cvuqdisk
2、验证grid环境
node1->find /home/grid/grid/ -name runcluvfy.sh
/home/grid/grid/runcluvfy.sh
Checking ASMLib configuration.
Node Name Status
------------------------------------ ------------------------
node1 passed
