4.4、修改启动项并加载新安装内核
编辑/boot/grub/menu.lst文件，加入红字部分
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grubafter making changes to this file
# NOTICE: You have a /boot partition. Thismeans that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/sda6
# initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu

完成后，重启系统
五、为Oracle配置操作系统
5.1、新建oinstall 和 dba 组
以root用户登录，在两节点上执行
[root@localhost /]# groupadd -g 200oinstall
[root@localhost linuxrdac-09.03.0C05.0233]#groupadd -g 201 dba
5.2、新建oracle用户
以root用户登录，在两节点上执行
[root@localhost /# useradd -u 201 -g oinstall-G dba oracle
[root@localhost /]# passwd oracle
Changing password for user oracle.
New UNIX password:
BAD PASSWORD: it is based on a dictionaryword
Retype new UNIX password:
passwd: all authentication tokens updatedsuccessfully.
[root@localhost linuxrdac-09.03.0C05.0233]#
5.3、配置host文件
以root用户登录，在两节点上执行
编辑/etc/hosts文件，加入如下红字内容内容
[root@localhost ~]# vi /etc/hosts
# Do not remove the following line, orvarious programs
# that require network functionality willfail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6

#######vip###############
156.16.34.26 mhdb01-vip
156.16.34.27 mhdb02-vip
#######priv#############
10.0.0.24 mhdb01-priv
10.0.0.25 mhdb02-priv
5.4、修改主机名
以root用户登录，在两节点上执行
编辑/etc/sysconfig/network
[root@localhost /]# vi/etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=mhdb02
完成后，重启服务
[root@localhost /]# service network restart
Shutting down interface eth0: [ OK ]
Shutting down interface eth1: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]
Bringing up interface eth1: [ OK ]
检查主机名修改成功
[root@localhost /]# hostname
mhdb02
[root@localhost /]#
5.5、提高oracle用户shell限制
以root用户登录，在两节点上执行
编辑/etc/security/limits.conf、/etc/pam.d/login 和 /etc/profile添加如下内容：
/etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
/etc/pam.d/login
session required /lib/security/pam_limits.so
/etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh"]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
5.6、配置内核参数
以root用户登录，在两节点上执行

5.8、配置oracle用户环境变量
以oracle用户登录，在两节点上执行
mhdb01
编辑/home/oracle/.bash_profile
[oracle@mhdb01 ~]$ pwd
/home/oracle
[oracle@mhdb01 ~]$ vi .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startupprograms
export EDITOR=vi
export ORACLE_SID=mhdb1
export ORACLE_BASE=/oracle
export ORACLE_HOME=$ORACLE_BASE/db10g
export ORA_CRS_HOME=$ORACLE_BASE/crs
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
exportPATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
export NLS_LANG='SimplifiedChinese_China'.ZHS16GBK
umask 022
#PATH=$PATH:$HOME/bin
#export PATH
mhdb02
[oracle@mhdb02 ~]$ pwd
/home/oracle
[oracle@mhdb02 ~]$ vi .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startupprograms
export EDITOR=vi
export ORACLE_SID=mhdb2
export ORACLE_BASE=/oracle
export ORACLE_HOME=$ORACLE_BASE/db10g
export ORA_CRS_HOME=$ORACLE_BASE/crs
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
exportPATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
export NLS_LANG='SimplifiedChinese_China'.ZHS16GBK
umask 022
#PATH=$PATH:$HOME/bin
#export PATH
如果想环境变量立即生效，执行命令：. ~/.bash_profile
5.9、创建安装目录
以root用户执行
mhdb01
[root@localhost ~]# mkdir /oracle
[root@localhost ~]# chown oracle:oinstall/oracle
mhdb02
[root@localhost /]# mkdir /oracle
[root@localhost /]# chown oracle:oinstall/oracle
以oracle用户执行
mhdb01
[oracle@mhdb01 ~]$ mkdir -p $ORACLE_HOME
[oracle@mhdb01 ~]$ mkdir -p $ORA_CRS_HOME
mhdb02
[oracle@mhdb02 ~]$ mkdir -p $ORACLE_HOME
[oracle@mhdb02 ~]$ mkdir -p $ORA_CRS_HOME
六、使用LVM配置存储
以root用户在mhdb01上执行
6.1、查看存储
[root@localhost ~]# fdisk -l
Disk /dev/sda: 437.9 GB, 437998583808 bytes
255 heads, 63 sectors/track, 53250cylinders

/dev/sda5 7267 8541 10241406 83 Linux
/dev/sda6 8542 53250 359125011 83 Linux
Disk /dev/sdb: 53.6 GB, 53687091200 bytes
64 heads, 32 sectors/track, 51200 cylinders
Units = cylinders of 2048 * 512 = 1048576bytes
Device Boot Start End Blocks Id System
Disk /dev/sdc: 53.6 GB, 53687091200 bytes
64 heads, 32 sectors/track, 51200 cylinders
Units = cylinders of 2048 * 512 = 1048576bytes
Disk /dev/sdc doesn't contain a validpartition table
Disk /dev/sdd: 53.6 GB, 53687091200 bytes
64 heads, 32 sectors/track, 51200 cylinders
Units = cylinders of 2048 * 512 = 1048576bytes
Disk /dev/sdd doesn't contain a validpartition table
Disk /dev/sde: 53.6 GB, 53687091200 bytes
64 heads, 32 sectors/track, 51200 cylinders
Units = cylinders of 2048 * 512 = 1048576bytes
Disk /dev/sde doesn't contain a validpartition table
Disk /dev/sdf: 53.6 GB, 53687091200 bytes
64 heads, 32 sectors/track, 51200 cylinders
Units = cylinders of 2048 * 512 = 1048576bytes
Disk /dev/sdf doesn't contain a validpartition table
Disk /dev/sdg: 53.6 GB, 53687091200 bytes
64 heads, 32 sectors/track, 51200 cylinders
Units = cylinders of 2048 * 512 = 1048576bytes
Disk /dev/sdg doesn't contain a validpartition table
[root@localhost ~]#
6.2、对磁盘分区
以root用户执行
先对/dev/sdb进行分区
[root@localhost ~]# fdisk /dev/sdb
The number of cylinders for this disk isset to 51200.
There is nothing wrong with that, but thisis larger than 1024,
and could in certain setups cause problemswith:
1) software that runs at boot time (e.g.,old versions of LILO)
2) booting and partitioning software fromother OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-51200, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK(1-51200, default 51200):
Using default value 51200
Command (m for help): t
Selected partition 1
Hex code (type L to list codes): 8e
Changed system type of partition 1 to 8e(Linux LVM)
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
[root@localhost ~]#
依次对剩余磁盘分区，最后结果为
[root@localhost ~]# fdisk -l

6.8、永久更改RAW权限
以root用户执行
编辑/etc/rc.local文件，加入如下内容
chown oracle:dba /dev/raw/*
chmod 660 /dev/raw/*
6.9、编辑oracle安装时使用的RAW配置文件
以oracle用户执行
在/home/oracle/目录下新建名为：raw_config的文件，添加如下内容
system=/dev/raw/raw3
sysaux=/dev/raw/raw4
undotbs1=/dev/raw/raw5
undotbs2=/dev/raw/raw6
users=/dev/raw/raw7
temp=/dev/raw/raw8
control1=/dev/raw/raw9
control2=/dev/raw/raw10
control3=/dev/raw/raw11
spfile =/dev/raw/raw12
redo1_1=/dev/raw/raw13

redo2_2=/dev/raw/raw18
redo2_3=/dev/raw/raw19
redo2_4=/dev/raw/raw20
pwdfile=/dev/raw/raw21
七、安装Oracle Clusterware
7.1、解压文件
[oracle@mhdb02 cluvfy]$ gunzip 10201_clusterware_linux_x86_64.cpio.gz
[oracle@mhdb02 cluvfy]$ cpio –idmv < clusterware_linux_x86_64.cpio
7.2、启动安装界面
以oracle用户执行（RH5是不受oracle10g支持的，所以需要在执行命令后加一个参数）
[oracle@mhdb02 /]$ /software/clusterware/runInstaller–ignoreSysPreReqs
********************************************************************************
Please run the script rootpre.sh as root onall machines/nodes. The script can be found at the toplevel of the CD orstage-area. Once you have run the script, please type Y to proceed
Answer 'y' if root has run 'rootpre.sh' soyou can proceed with Oracle Clusterware installation.
Answer 'n' to abort installation and thenask root to run 'rootpre.sh'.
********************************************************************************

[oracle@mhdb02 ~]$
7.3、执行root脚本
以root用户先在两个节点执行脚本：
/oracle/oraInventory/orainstRoot.sh
再执行
/oracle/crs/root.sh
mhdb02
[root@mhdb02 raw]#/oracle/oraInventory/orainstRoot.sh

[root@mhdb02 raw]#
注意，这里执行失败是因为oracle BUG: 4679769
解决办法：
解压补丁：p4679769_10201_LINUX32.zip
将解压出的 clsfmt.bin拷贝到$ORA_CRS_HOME/bin下替换原来的文件即可，注意先备份原来文件，两个节点都要替换
重新执行之前先用dd命令清除raw上信息
dd if=/dev/zeroof=/dev/raw/raw1 bs=1Mcount=200

7.4、调用vipca
以root用户执行
mhdb01
[root@mhdb01 raw]#/oracle/crs/bin/vipca
/oracle/crs/jdk/jre//bin/java:error while loading shared libraries: libpthread.so.0: cannot open sharedobject file: No such file or directory
[root@mhdb01 raw]#
解决办法：
在两节点上，
1、分别修改 $CRS_HOME/bin目录下的srvctl和vipca文件，在vipca文件ARGUMENTS=""行之前和srvctl文件的exportLD_ASSUME_KERNEL行之后增加 unset LD_ASSUME_KERNEL 语句。
2、在任意一个节点上使用oifcfg配置public和vip网络
[root@rac1 bin]# ./oifcfgsetif -global eth0/192.168.2.0:public
[root@rac1 bin]# ./oifcfgsetif -global eth1/192.168.0.0:cluster_interconnect
[root@rac1 bin]# ./oifcfggetif
