以CENTOS6.8系统为例部署ORACLE11g RAC和DNS配置

本文所需要的全部文档均位于文末附录中

本文章以两个节点为例进行安装

在virtual box创建虚拟机时，网卡1为桥接网卡，网卡二为仅主机模式

创建两块磁盘，模式设置为可共享，都添加到两个虚拟机中

在虚拟介质管理中进行设置

虚拟机的创建明细如下

在两个系统安装完成后，进入network connection配置

把动态地址改为静态地址，手动输入地址、子网掩码及网关

将两个节点的公共网卡地址写入DNS server

进入 /etc/hosts 写入两个节点的网卡信息

[root@rac01 ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

chkconfig named on ##设置开机自启动

DNS解析服务启动

service named start

补一个rpm 包 rpm -ivh pdksh-5.2.14-30.x86_64.rpm

禁用防火墙，关闭防火墙服务

chkconfig iptables off
service iptables stop

修改selinux/config内的文件

vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

创建用户和组

groupadd -g 2000 oinstall
groupadd -g 2200 asmadmin
groupadd -g 2201 asmdba
groupadd -g 2202 asmoper
groupadd -g 2300 dba
groupadd -g 2301 oper
useradd -m -u 1100 -g oinstall -G asmadmin,asmdba,asmoper,dba -d /home/grid -s /bin/bash -c "Grid Infrastructure Owner" grid
useradd -m -u 1101 -g oinstall -G dba,oper,asmdba -d /home/oracle -s /bin/bash -c "Oracle Software Owner" oracle
passwd grid
passwd oracle

修改用户和组的权限

mkdir -p /opt/ora11g/grid
mkdir -p /opt/ora11g/11.2.4/grid
chown -R grid:oinstall /opt
mkdir -p /opt/ora11g/oracle
chown oracle:oinstall /opt/ora11g/oracle
chmod -R 775 /opt

节点1：脚本1

节点2：脚本1

节点1：脚本2

节点2：脚本2

之后完成集群件的安装

启动asmca

选择create

选择不冗余

选择mount all

查看crs状态（实例与监听，后面启动）

[grid@rac01 ~]$ crsctl status res -t

注销切换到Oracle用户

启动Oracle客户端程序安装

不勾选接受支持（因为不是花钱买的正版呀）

选择跳过软件更新

选择仅安装数据库软件

配置SSH

选择语言

选择企业版

这个警告是要求Ping cluster-scan。可略过

执行安装

分别在节点1节点2上

执行脚本

/opt/ora11g/oracle/product/11.2.4/dbhome_1/root.sh

启动dbca图形化

create database

选择 Select all 输入数据库名和SID

不勾选

设定数据库口令

设定字符集

勾选第二项执行脚本

安装完成后，分别在节点一二查看实例名，验证是否安装成功

节点2Oracle用户

节点2grid用户

节点1Oracle用户

节点1grid用户
