篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Rhel7.3_Oracle12cR2的RAC搭建安装相关的知识，希望对你有一定的参考价值。

本次文档演示在Linux7环境安装Oracle12R2版本的RAC数据库。

安装环境：

虚拟机：vbox5.1

操作系统：rhel-server-7.3-x86_64

Grid集群安装包：linuxx64_12201_grid_home

DB数据库安装包：linuxx64_12201_database

IP划分如下：

Public-IP

192.168.56.101 ol7-122-rac1

192.168.56.102 ol7-122-rac2

Private-IP

192.168.1.101 ol7-122-rac1-priv

192.168.1.102 ol7-122-rac2-priv

Virtual-IP

192.168.56.103 ol7-122-rac1-vip

192.168.56.104 ol7-122-rac2-vip

Scan-IP

192.168.56.105

192.168.56.106

192.168.56.107

附：dns为ol7-122-scan.fly.cn

ASM磁盘划分如下：

OCR 3块：asm-diskc 2G 、asm-diskd 2G、asm-diske 2G

GIMR 1块：asm-diskf 40G

数据 1块：asm-diskg 10G

一：linux配置

Linux安装时选项包如下：

Server with GUI
Hardware Monitoring Utilities
Large Systems Performance
Network file system client
Performance Tools
Compatibility Libraries
Development Tools

虚拟机配置如下：

先配置一台虚拟机(第一个节点 ol7-122-rac1)

内存设置6G

添加安装ORACLE软件盘目录为：/u01

添加ASM存储盘(3块OCR，1块GIMR，1块存放数据)

设置网卡，网卡1位NAT方式

网卡2为主机host-only方式(配置Public-IP)

网卡3为内网方式(配置Private-IP)

二：安装前准备

修改 /etc/selinux/config配置

[root@ol7-122-rac1 ~]# vi /etc/selinux/config

SELINUX=disabled

关闭防火墙

[root@ol7-122-rac1 ~]# systemctl stop firewalld
[root@ol7-122-rac1 ~]# systemctl disable firewalld

配置内核参数：

[root@ol7-122-rac1 ~]# vi /etc/sysctl.conf
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
kernel.panic_on_oops = 1
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.conf.all.rp_filter = 2
net.ipv4.conf.default.rp_filter = 2
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500

修改生效：
[root@ol7-122-rac1 ~]# /sbin/sysctl –p

修改系统限制参数

[root@ol7-122-rac1 ~]# vi /etc/security/limits.conf

增加组和用户：

[root@ol7-122-rac1 ~]# groupadd -g 54321 oinstall
[root@ol7-122-rac1 ~]# groupadd -g 54322 dba
[root@ol7-122-rac1 ~]# groupadd -g 54323 oper

修改grid环境变量如下：
export ORACLE_SID=+ASM2

 
修改oracle环境变量如下：
export ORACLE_SID=orcl2

修改rac1主机的磁盘介质类型，为共享类型

(以dg_1磁盘为例，OCR和GIMR同理修改)

在rac2主机添加rac1的上面修改的共享磁盘(以dg_1磁盘为例，OCR和GIMR同理修改)：

设置SSH信任关系

基本步骤：

1)设置rac1的rsa和dsa加密，然后都追加到authorized_keys文件中

2)再把rac1的authorized_keys拷贝到rac2中

3)同样rac2的rsa和dsa加密，然后把rac2的rsa和dsa加密追加到authorized_keys文件中

4)再把rac2的authorized_keys文件拷贝到rac1中，覆盖之前的authorized_keys文件

注1：这样的话rac1和rac2的authorized_keys文件中都有了彼此的rsa和dsa加密

注2：需设置grid和oracle两个用户(这里以oracle用户为例)

1、Rac1服务器设置：

(1)设置rsa和dsa加密：

[oracle@ol7-122-rac1 ~]$ ssh-keygen -t rsa
[oracle@ol7-122-rac1 ~]$ ssh-keygen -t dsa

(2)把rsa和dsa加密都放置到authorized_keys文件中：

[oracle@ol7-122-rac1 ~]$ cat .ssh/id_rsa.pub >> .ssh/authorized_keys
[oracle@ol7-122-rac1 ~]$ cat .ssh/id_dsa.pub >> .ssh/authorized_keys

(3)把rac1的authorized_keys拷贝到rac2中：

[oracle@ol7-122-rac1 ~]$ cd/home/oracle/.ssh

[oracle@ol7-122-rac1 .ssh]$ scp authorized_keys 192.168.56.102:/home/oracle/.ssh/

2、Rac2服务器设置：

(1)设置rsa和dsa加密：

[oracle@ol7-122-rac2 ~]$ ssh-keygen -t rsa
[oracle@ol7-122-rac2 ~]$ ssh-keygen -t dsa

(2)把rac2的rsa和dsa加密都放置到从rac1拷贝来的authorized_keys文件中：

[oracle@ol7-122-rac2 ~]$ cat .ssh/id_rsa.pub >> .ssh/authorized_keys
[oracle@ol7-122-rac2 ~]$ cat .ssh/id_dsa.pub >> .ssh/authorized_keys

(3)把rac2中的authorized_keys文件拷贝到rac1中，覆盖之前的authorized_keys文件：

[oracle@ol7-122-rac2 ~]$ cd/home/oracle/.ssh
[oracle@ol7-122-rac2 .ssh]$ scp authorized_keys 192.168.56.101:/home/oracle/.ssh/

3、查看一下rac1和rac2相同的authorized_keys文件，如下：

[oracle@ol7-122-rac1 .ssh]$ more authorized_keys

4、测试SSH：

Rac1和 rac2分别测试，可以正常返回日期即可：

[oracle@ol7-122-rac1 ~]$ ssh ol7-122-rac1 date
[oracle@ol7-122-rac1 ~]$ ssh ol7-122-rac1-priv date
[oracle@ol7-122-rac1 ~]$ ssh ol7-122-rac2 date
[oracle@ol7-122-rac1 ~]$ ssh ol7-122-rac2-priv date

绑定UDEV共享磁盘

添加共享磁盘顺序要一致

Oracle12C R2+RAC安装测试

Rhel7.3_Oracle12cR2的RAC搭建安装

一：linux配置

Linux安装时选项包如下：

虚拟机配置如下：

二：安装前准备

修改 /etc/selinux/config配置

关闭防火墙

配置内核参数：

修改系统限制参数

增加组和用户：

增加ip地址：

查看网卡信息：

查看scanip的dns配置信息(具体配置可参考 点击打开链接)

建立文件路径

修改grid用户的环境变量

修改oracle用户的环境变量

克隆rac1节点的虚拟机，为节点2 rac2

修改rac1主机的磁盘介质类型，为共享类型

设置SSH信任关系

1、Rac1服务器设置：

(1)设置rsa和dsa加密：

(2)把rsa和dsa加密都放置到authorized_keys文件中：

(3)把rac1的authorized_keys拷贝到rac2中：

2、Rac2服务器设置：

(1)设置rsa和dsa加密：

(2)把rac2的rsa和dsa加密都放置到从rac1拷贝来的authorized_keys文件中：

(3)把rac2中的authorized_keys文件拷贝到rac1中，覆盖之前的authorized_keys文件：

3、查看一下rac1和rac2相同的authorized_keys文件，如下：

4、测试SSH：

绑定UDEV共享磁盘

三：安装GRID软件

配置asm

四：安装ORACLE软件

五：安装数据库

查看scanip的dns配置信息(具体配置可参考点击打开链接)
