因为客户数据库需要打补丁，所以安装相似测试环境。需要先安装Oracle RAC 10.2.0.1 然后再升级到10.2.0.5。因为我有很多篇关于安装的文章，所以这篇只说关键步骤，以及遇见的bug安装错误。

注意：我已经在RedHat 6.3测试过，不能完成安装，主要是在跑root.sh脚本的时候无法通过。换成redhat 5.8不会出现这种问题。

Steps:
1、防火墙and selinux
2、kernel parameter
3、source limit
4、create user and group
5、建立信任关系
6、安装依赖包
7、配置用户环境变量和密码
8、创建裸设备
9、配置映射文件
10、安装grid
11、升级grid
12、配置vipca
13、安装database
14、升级database
15、创建rac数据库

因为10g没有11g自带工具可以很方便的打通道，所以比较麻烦，，不过这里我还是直接是把11g软件拿来解压用其工具自动建立信任关系。
安装依赖包：
yum install -y libXau* libxcb* libX11* libXext* libICE* libuuid* libSM* libXt* libXi* libXtst* libXp* glibc-devel* libaio-devel* libaio* compat-libstdc++* libXpm* libXp-devel* libXpm-devel* compat-libstdc++* compat-libstdc++* compat-libstdc++* gcc-4.4.6* gcc-c++*

创建裸设备：
我这里是用的Virtual Box建立的几块盘，这里提醒一下，需要把属性盘设置为共享，不然会报错。这里我前面文章也有说到

配置映射文件：
[oracle@rac1 ~]$ cat zbdba.txt
system=/dev/raw/raw6
sysaux=/dev/raw/raw7
example=/dev/raw/raw8
temp=/dev/raw/raw/raw11
users=/dev/raw/raw12

undotbs2=/dev/raw/raw14
redo1_1=/dev/raw/raw5

redo2_2=/dev/raw/raw18
control1=/dev/raw/raw19
control2=/dev/raw/raw20
pwdfile=/dev/raw/raw9
spfile=/dev/raw/raw10

安装grid软件没什么问题，主要是跑root.sh脚本的时候。
会出现 Failed to upgrade Oracle Cluster Registry configuration错误，该错误的原因是一个bug，在文档466673.1有明确说明。所以下载
补丁4679769
解压该补丁，然后：
cp ./4679769/clsfmt.bin /u01/app/crs/bin/clsfmt.bin
将其覆盖

然后测试：
/u01/app/crs/bin/clsfmt.bin ocr /dev/raw/raw1
clsfmt: successfully initialized file /dev/raw/raw1
