一，虚拟机规划
(1)虚拟机：添加三块网卡 eth0 eth1 eth2 ,分别用于内网，心跳，外网
RAC1 内网：192.168.1.10/24 心跳：192.168.2.10/24 VIP：192.168.1.100 外网：DHCP
RAC2 内网：192.168.1.11/24 心跳：192.168.2.11/24 VIP：192.168.1.101 外网：DHCP
(2)磁盘大小：20GB 安装系统时使用逻辑卷管理磁盘，以方便后续空间不够时进行扩展
系统：RHEL5.8
(3)共享磁盘
OCR磁盘：100M
Voting disk：100M
两块作为ASM磁盘：
asmdisk1:2GB
asmdisk2:2GB
二，配置
1.主节点配置
(1)网络设置
修改网络配置文件
(2)防火墙和SElinux
关闭防火墙
service iptables stop
禁用SELinux（需要重启主机）
编辑/etc/selinux/config
修改
SELINUX=disabled
(3)修改主机名
编辑/etc/sysconfig/network
设置
HOSTNAME=db10a
(4)修改/etc/hosts文件
添加
##Public Network - (eth0)
192.168.1.10 db10a
192.168.1.11 db10b
##Private Interconnect - (eth1)
192.168.2.10 db10a-priv
192.168.2.11 db10b-priv
##Public Virtual IP (VIP) addresses - (eth0)
192.168.1.100 db10a-vip
192.168.1.101 db10b-vip
(5)创建所需用户和用户组
groupadd -g oinstall
groupadd -g dba
useradd -m -u -g oinstall -G dba -d /home/oracle -s /bin/bash -c "Oracle Software Owner" oracle
设置密码：
passwd oracle
(6)创建所需目录并授权(其中media为存放oracle所需软件的目录)
mkdir -p /oracle/media
chown -R oracle:oinstall /oracle/media/
chmod -R /oracle/media/
mkdir -p /u01/crs1020
chown -R oracle:oinstall /u01/crs1020
chmod -R /u01/crs1020/
mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app/oracle/
chmod -R /u01/app/oracle/
(7)修改环境变量文件
su - oracle
vi .bash_profile
把文件中的内容替换
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH

alias tnsnames='vi $ORACLE_HOME/network/admin/tnsnames.ora'
alias listener='vi $ORACLE_HOME/network/admin/listener.ora'
(8)修改内核参数
vi /etc/sysctl.conf
添加：
kernel.shmmax =
kernel.shmmni =
kernel.sem =
fs.file-max =
net.ipv4.ip_local_port_range =
net.core.rmem_default =
net.core.rmem_max =
net.core.wmem_default =
net.core.wmem_max =
生效
sysctl -p
(9)限制参数
编辑/etc/security/limits.conf
添加：
oracle soft nproc
oracle hard nproc
oracle soft nofile
oracle hard nofile
在/etc/pam.d/login中添加：
session required /lib/security/pam_limits.so
如下：
cat >> /etc/pam.d/login << EOF
session required /lib/security/pam_limits.so
EOF
(10)设置计时器
cat >> /etc/rc.local << EOF
modprobe hangcheck-timer hangcheck-tick= hangcheck_margin=
EOF
(11)检查安装包并安装所需要的rpm包
rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n' binutils \
compat-libstdc++- \
elfutils-libelf \
elfutils-libelf-devel \
elfutils-libelf-devel-static \
gcc \
gcc-c++ \
glibc \
glibc-common \
glibc-devel \
glibc-headers \
kernel-headers \
ksh \
libaio \
libaio-devel \
libgcc \
libgomp \
libstdc++ \
libstdc++-devel \
make \
sysstat \
unixODBC \
unixODBC-devel \
libXp
可配置本地yum源
a. mount /dev/cdrom /mnt
b. cat >> /etc/yum.repos.d/dvd.repo<<EOF
[dvd]
name=install dvd
baseurl=file:///mnt/Server
enabled=
gpgcheck=
EOF
c. yum clean all
d. yum list
配置成功后，安装缺失软件包
(12)配置并启动ntp服务
ntp服务
rpm -qa | grep ntp
vi /etc/ntp.conf
restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap service ntpd start chkconfig ntpd on
(13)关闭虚拟机，添加共享磁盘(这一步最好在前面开始的时候做，否则多重启一下虚拟机系统)
添加4块儿磁盘：ocr磁盘为100M
voting disk 为:100M
ASM1:2G
ASM2:2G
添加的4块儿磁盘要与本地的磁盘不要设置在同一总线下
在节点以的vmx文件中添加(开启前添加)：
disk.locking="false"
diskLib.dataCacheMaxSize = ""
diskLib.dataCacheMaxReadAheadSize = ""
diskLib.DataCacheMinReadAheadSize = ""
diskLib.dataCachePageSize = ""
diskLib.maxUnsyncedWrites = ""
scsi1:.deviceType = "disk"
scsi1:.deviceType = "disk"
scsi1:.deviceType = "disk"
scsi1:.deviceType = "disk"
disk.EnableUUID ="true"
对4块儿盘进行分区
fdisk /dev/sdb
分别为：sdb1,sdc1,sdd1,sde1
使用udev进行绑定裸设备
编辑/etc/udev/rules.d/60-raw.rules
添加：
ACTION=="add", KERNEL=="sdb", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdc", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdd", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="sde", RUN+="/bin/raw /dev/raw/raw4 %N"
KERNEL=="raw[1-4]", OWNER="oracle", GROUP="oinstall", MODE=""
重启udev
start_udev
查看：
[root@db10a ~]# raw -qa
/dev/raw/raw1: bound to major , minor
/dev/raw/raw2: bound to major , minor
/dev/raw/raw3: bound to major , minor
/dev/raw/raw4: bound to major , minor
[root@db10a ~]# ls -l /dev/raw
total
crw-rw---- oracle oinstall , Sep : raw1
crw-rw---- oracle oinstall , Sep : raw2
crw-rw---- oracle oinstall , Sep : raw3
crw-rw---- oracle oinstall , Sep : raw4
注意权限和属组
使用上面的方式进行绑定的时候报磁盘没有共享的错误
使用rawdevice方式进行绑定
在/etc/sysconfig/rawdevices 中加入：
/dev/raw/raw1 /dev/sdb1
/dev/raw/raw2 /dev/sdc1
/dev/raw/raw3 /dev/sdd1
/dev/raw/raw4 /dev/sde1
将赋权限的命令加到/etc/rc.d/rc.local文件中，以便重启的时候对裸设备赋正确的权限
chown –R oracle:oinstall /dev/raw/raw*
chmod /dev/raw/raw*
2.副节点设置
(1)复制或者克隆节点一
(2)修改的地方有
IP地址
主机名
oracle用户中的实例名(这里是testdb102)
3.配互信
在主节点
节点一
su - oracle

Mon May :: CST
RACDB1@rac1 /home/oracle$
校验完毕同时切回了 rac1 节点
再次进行测试看看是否需要手动操作
RACDB1@rac1 /home/oracle$ sh ssh.sh
Mon May :: CST
Mon May :: CST
Mon May :: CST
Mon May :: CST
Last login: Mon May :: from rac1
RACDB2@rac2 /home/oracle$ sh ssh.sh
Mon May :: CST
Mon May :: CST
Mon May :: CST
Mon May :: CST
Last login: Mon May :: from rac2
一去一回，完全不用进行手动操作，两个节点间的互信关系就此配置完毕！！！
PS：保证两节点的时间同步，在二节点停止ntpd服务，并部署下面的脚本，1s进行一次时间同步
[root@rac2 ~]# cat ntpdate_to_rac1.sh -----注意：使用这个脚本的时候客户端的ntpd服务不启动
while :; do ntpdate db10a; sleep ; done
如若仍不满足需求，可以在后台同时启动多个同步脚本。后台启动方法如下。
[root@rac2 ~]# nohup sh ntpdate_to_rac1.sh >> ntpdate_to_rac1.log&
[root@db10b ~]# tail -f ntpdate_to_rac1.log

Sep :: ntpdate[]: adjust time server 192.168.1.10 offset -0.000017 sec
.....
三，安装
1.安装cluster软件
解压：
gzip -d 10201_clusterware_linux_x86_64.cpio.gz
gzip -d 10201_database_linux_x86_64.cpio.gz
cpio -idmv < 10201_clusterware_linux_x86_64.cpio
cpio -idmv < 10201_database_linux_x86_64.cpio
检查安装环境：
cd /oracle/media/clusterware/
./runcluvfy.sh stage -pre crsinst -n db10a,db10b -verbose
检查报：
Could not find a suitable set of interfaces for VIPs.
忽略，继续安装
安装cluster软件的最后要执行两个脚本
[root@rac1 ~]# /u01/app/oracle/oraInventory/orainstRoot.sh Changing permissions of /u01/app/oracle/oraInventory to .
Changing groupname of /u01/app/oracle/oraInventory to oinstall.
The execution of the script is complete [root@rac2 ~]# /u01/app/oracle/oraInventory/orainstRoot.sh Changing permissions of /u01/app/oracle/oraInventory to .
Changing groupname of /u01/app/oracle/oraInventory to oinstall.
The execution of the script is complete
第二个脚本在第一个节点 rac1 上执行
[root@rac1 ~]# /u01/crs1020/root.sh -----时间较长
在第二个节点 rac2 上执行这个脚本前，完成以下工作
[root@rac2 ~]# cd /u01/crs1020/bin/
修改
[root@rac2 bin]# vi vipca
在
if [ "$arch" = "i686" -o "$arch" = "ia64" ] then
LD_ASSUME_KERNEL=2.4.
export LD_ASSUME_KERNEL
fi
下面加入
unset LD_ASSUME_KERNEL
修改
[root@rac2 bin]# vi srvctl
在
LD_ASSUME_KERNEL=2.4.
export LD_ASSUME_KERNEL
下面加入
unset LD_ASSUME_KERNEL
此时
Rac2 上执行
[root@rac2 ~]# /u01/crs1020/root.sh
最后还会报错
Running vipca(silent) for configuring nodeapps
Error (Native: listNetInterfaces:[]) [Error (Native: listNetInterfaces:[])]
解决办法：
[root@rac2 bin]# ./oifcfg getif [root@rac2 bin]# ./oifcfg iflist eth0 192.168.1.0 eth1 192.168.2.0 eth2 192.168.0.0
[root@rac2 bin]# ./oifcfg setif -global eth0/192.168.1.0:public
[root@rac2 bin]# ./oifcfg setif -global eth1/192.168.2.0:cluster_interconnect
[root@rac2 bin]# ./oifcfg getif eth0 192.168.1.0 global public eth1 192.168.2.0 global cluster_interconnect
然后 rac2 上启动 vipca 图形界面
[root@rac2 ~]# cd /u01/crs1020/bin/
[root@rac2 bin]# ./vipca
点击 next
VIP配置成功后（显示如下）
2.安装数据库软件
在安装的时候选择只安装软件
3.listener配置
手工配置或者使用netca配置（推荐使用netca）
安装完成之后使用crs_stat命令查看：
[root@db10b ~]# /u01/crs1020/bin/crs_stat -t -v
Name Type R/RA F/FT Target State Host
----------------------------------------------------------------------
ora....0A.lsnr application / / ONLINE ONLINE db10a

ora.db10b.gsd application / / ONLINE ONLINE db10b
ora.db10b.ons application / / ONLINE ONLINE db10b
ora.db10b.vip application / / ONLINE ONLINE db10b
4.创建ASM实例和创建数据库
最后一步，使用dbca建库，建库完成后检查服务
testdb101@db10a /home/oracle$ crs_stat -t -v
Name Type R/RA F/FT Target State Host
----------------------------------------------------------------------
ora....SM1.asm application / / ONLINE ONLINE db10a

ora....db10.db application / / ONLINE ONLINE db10b
ora.....inst application / / ONLINE ONLINE db10a

四，问题总结
这次安装RAC是遇到问题最多的一次，一一总结如下：
第一，在安装最后执行两个脚本，第一个脚本在两个节点顺利执行，第二个脚本root.sh在主节点顺利执行，在副节点执行的时候等了n长时间报下面的错误：
[root@db10b bin]# /u01/crs1020/root.sh

.
..(后面一直重复同样的错误信息)
解决方法：
有三种说法：
.防火墙（排除）
.
CRS-:The OCR location /dev/raw/raw4 is inaccessible. 手动格式/dev/raw/raw4：
dd if=/dev/zero of=/dev/raw/raw4 bs=1m
然后
rm -fr /etc/oracle on all nodes 然后在每个节点
$CRS_HOME/root.sh .我应该是属于下面的一种情况：（因为我的二节点上没有下面的参数）
diskLib.dataCacheMaxSize = ""
diskLib.dataCacheMaxReadAheadSize = ""
diskLib.DataCacheMinReadAheadSize = ""
diskLib.dataCachePageSize = ""
diskLib.maxUnsyncedWrites = "" 还有在后面的fdisk，只用对rac1操作就行了，重启后cat /proc/partiion 确定2台虚拟机上都是一样的配置；
另外附上完全清理CRS，卸载RAC的方法：

rm -f /etc/inittab.crs vi /etc/inittab 删除掉与crs和css有关的服务
解决了上面的错误，但是在副节点上再次执行root.sh的时候报下面的错误：

解决：
这个错误是由于64位的系统上缺失32位的glibc-devel包导致
在2上节点安装32位的glibc-devel-2.3.4-2.43.i386.rpm，
然后再重新安装CRS
注意：必要是2个节点上都要安装这个包，而且需要重新安装CRS
解决后继续安装，执行root.sh的时候报下面的错误就正常了，这个是oracle10g 10201上面的一个bug，在10205上解决

然后再root用户下启动vipca配置好VIP
