为数据和快速恢复去创建ASM磁盘组
只在节点rac1执行即可，进入grid用户下

[grid@rac1 grid]$ srvctl status asm -a
ASM is running on rac2,rac1
ASM is enabled.
[grid@rac1 grid]$ ps -ef|grep lsnr|grep -v 'grep'|grep -v 'ocfs'|awk '{print$9}'
LISTENER_SCAN1
LISTENER
[grid@rac1 grid]$ asmca

安装grid时配置的OCR盘已存在
添加DATA盘，点击create，

同样创建FRA盘，

ASM磁盘组情况

安装Oracle database软件（RAC）
1.安装流程
只需要在节点rac1上执行即可

[root@rac1 software]# unzip p13390677_112040_Linux-x86-64_1of7.zip 
[root@rac1 software]# unzip p13390677_112040_Linux-x86-64_2of7.zip 
[root@rac1 software]# chown  -R oracle:oinstall database/
[root@rac1 software]# chmod -R 775 database/
[root@rac1 software]# 
[root@rac1 ~]# su - oracle
[oracle@rac1 ~]$ echo $DISPLAY
192.168.182.1:0.0
[oracle@rac1 ~]$ 
[oracle@rac1 ~]$ cd db/database
[oracle@rac1 database]$ ./runInstaller

进入图形化界面，跳过更新


跳过软件更新

只安装软件
**
选择Oracel Real Application Clusters database installation按钮（默认），确保勾选所有的节点

这里的SSH Connectivity是配置每个节点之间的oracle用户互信，前面已手动配置过，可以不配

选择语言English

选择企业版

安装Oracle软件路径，其中ORACLE_BASE,ORACLE_HOME均选择之前配置好的，默认选择
默认
oracle权限授予用户组

这两个错误前面有说明，忽略

错误提示：
如果有
1. Node Application Existence
PRVF-4557:Node application "ora.rac1.vip" is offline on node "rac1"
说明是rac1 出异常，vip飘到rac2，正常rac1恢复会自动飘回，可以手动
crsctl relocate resource ora.cnsz001.vip

2. Node Connectivity
检查
[grid@cnsz002 grid]$ ./runcluvfy.sh stage -post hwos -n cnsz001,cnsz002 -verbose  

3. 在RHEL7或者OL7上安装11.2.0.4时遇到错误 “undefined reference to symbol ‘B_DestroyKeyObject’”
来源于：
Installation of Oracle 11.2.0.4 on OL7 fails with “undefined reference to symbol ‘B_DestroyKeyObject’” error (文档 ID 1965691.1)

适用于：
Oracle Database - Enterprise Edition - Version 11.2.0.4 to 11.2.0.4 [Release 11.2]
Oracle Database - Standard Edition - Version 11.2.0.4 to 11.2.0.4 [Release 11.2]
Linux x86-64


usr/bin/ld: /u01/app/oracle/product/11.2.0/dbhome_1/sysman/lib//libnmectl.a(nmectlt.o): undefined reference to symbol ‘B_DestroyKeyObject’
/usr/bin/ld: note: ‘B_DestroyKeyObject’ is defined in DSO /u01/app/oracle/product/11.2.0/dbhome_1/lib/libnnz11.so so try adding it to the linker command line
 /u01/app/oracle/product/11.2.0/dbhome_1/lib/libnnz11.so: could not read symbols: Invalid operation
 collect2: error: ld returne
 INFO: d 1 exit status

原因：
未公开的bug 19692824

解决方法：
01) 忽略 Oracle 11.2.0.4安装过程中的 undefined symbol error 错误并继续安装，软件安装过程将会在没有错误的情况下成功结束
02) 下载并安装patch 19692824
03) 为11.2.0.4的HOME设置诸如ORACLE_HOME, PATH等等的环境变量，并使用下面的命令来重新编译失败的target

安装RAC的概要信息

开始安装，会自动复制到其他节点

安装完，在每个节点用root用户执行脚本

[root@rac1 ~]# /u01/app/oracle/product/11.2.0/db_1/root.sh
Performing root user operation for Oracle 11g 

The following environment variables are set as:
    ORACLE_OWNER= oracle
    ORACLE_HOME=  /u01/app/oracle/product/11.2.0/db_1

Enter the full pathname of the local bin directory: [/usr/local/bin]: 
The contents of "dbhome" have not changed. No need to overwrite.
The contents of "oraenv" have not changed. No need to overwrite.
The contents of "coraenv" have not changed. No need to overwrite.

Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root script.
Now product-specific root actions will be performed.
Finished product-specific root actions.
[root@rac1 ~]# 

安装完成，close
至此在RAC双节点上完成oracle软件安装，安装日志在

[oracle@rac1 database]$ ./runInstaller
