再做 Oracle 11gR2 RAC部署2
下面说明软件环境，就开始部署。
虚拟环境是：VMware workstation 10
虚拟机平台： OEL linux 5.5 x64
依赖包：

oracleasm-2.6.18-194.el5-2.0.5-1.el5.x86_64.rpm
oracleasmlib-2.0.4-1.el5.x86_64.rpm
这次先配node1和node2的主机名，ip地址，最后再部署DNS服务。
主机与ip地址规划如下:
配置完成如下所示：
修改node1和node2主机名
vi /etc/hosts 编辑hosts，填写如下内容。
node1 如下:
[root@node1 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 node1.localdomain node1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
# node1
192.168.137.151 node1.localdomain node1
192.168.137.153 node1-vip.localdomain node1-vip
192.168.119.151 node1-priv.localdomain node1-priv
# node2
192.168.137.152 node2.localdomain node2
192.168.137.154 node2-vip.localdomain node2-vip
192.168.119.152 node2-priv.localdomain node2-priv
# scan-ip
192.168.137.158 scan-cluster.localdomain scan-cluster
node2如下:
[root@node2 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 node2.localdomain node2 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
# node1
192.168.137.151 node1.localdomain node1
192.168.137.153 node1-vip.localdomain node1-vip
192.168.119.151 node1-priv.localdomain node1-priv
# node2
192.168.137.152 node2.localdomain node2
192.168.137.154 node2-vip.localdomain node2-vip
192.168.119.152 node2-priv.localdomain node2-priv
# scan-ip
192.168.137.158 scan-cluster.localdomain scan-cluster
配置DNS服务器
目的是保证scan-ip可以被解析，可以选择在node1或node2上配置，也可以单独配置，这里我单独配置。
DNS服务服务器ip地址192.168.137.61
详细过程如下：
yum install named -y 安装DNS服务
编辑各个配置文件:
以下是主配置文件named.conf
[root@AMH ~]# vim /var/named/chroot/etc/named.conf
以下是辅助区域配置文件
[root@AMH ~]# vim /etc/named.rfc1912.zones
zone “localhost.localdomain” IN {
type master;
file “named.localhost”;
allow-update { none; };
};
zone “localdomains” IN {
type master;
file “localdomain.zone”;
allow-update { none; };
};
zone “localhost” IN {
type master;
file “named.localhost”;
allow-update { none; };
};
zone “0.in-addr.arpa” IN {
type master;
file “named.empty”;
allow-update { none; };
};
zone “138.168.192.in-addr.arpa” IN {
type master;
file “138.168.192.in-addr.arpa”;
allow-update { none; };
};
以下是反向作用域文件
以下是正向解析域文件
配置完成后,执行/etc/init.d/named start 启动DNS服务
node1和node2在 /etc/resolv.conf中填写nameserver 192.168.137.61,保存退出.
测试DNS正反向解析
node1测试
node2测试
可见scan-ip被正常解析. 下一部分将配置RAC 集群软件 ，oracle的用户，用户组，环境变量，资源限制等等，然后创建共享磁盘。
