環境如下：
Linux操作系統：Centos 6.5 64bit （這個版本的redhat 6內核等OS在安裝grid最後執行root.sh時會出現crs-4124，是oracle11.2.0.1的bug）
VMware version：Workstation 8.0.3 build-703057
Oracle版本：11G R2 grid/oracle 64位 11.2.0.1.0 for linux
步驟規劃：
1，配置虛擬機、安裝Linux操作系統
2，配置OS
3，配置ASM
4，安裝Oracle grid
5，安裝Oracle database
6，創建ASM磁盤組
7，建立數據庫實例
1，配置虛擬機、安裝Linux操作系統
1.1 新建虛擬機：RAC1和RAC2，並安裝OS
下載Centos的iso後新建虛擬機後安裝即可，這裏略。注意內存分配，每個虛擬機至少1.5G內存比較好，我的機器8G內存，給每個虛擬機分了2G，給每個虛擬機分配50GB硬盤容量，配置2個橋接網卡。
1.2 配置Share Disks
新建共享硬盤，在DOS VM安裝目錄下執行：
cd \D F:/Software/vm8/
vmware-vdiskmanager.exe -c -s 1000Mb -a lsilogic -t 2 K:\VMDisk\Sharedisk\ocr.vmdk
vmware-vdiskmanager.exe -c -s 1000Mb -a lsilogic -t 2 K:\VMDisk\Sharedisk\ocr2.vmdk
vmware-vdiskmanager.exe -c -s 1000Mb -a lsilogic -t 2 K:\VMDisk\Sharedisk\votingdisk.vmdk
vmware-vdiskmanager.exe -c -s 20000Mb -a lsilogic -t 2 K:\VMDisk\Sharedisk\data.vmdk
vmware-vdiskmanager.exe -c -s 10000Mb -a lsilogic -t 2 K:\VMDisk\Sharedisk\backup.vmdk
配置虛擬機RAC1 RAC2目錄下的vmx虛擬機配置文件，在行最後添加如下：
scsi1.present = "TRUE"
scsi1.virtualDev = "lsilogic"
scsi1.sharedBus = "virtual"
scsi1:1.present = "TRUE"
scsi1:1.mode = "independent-persistent"
scsi1:1.filename = "K:\VMDisk\Sharedisk\ocr.vmdk"
scsi1:1.deviceType = "plainDisk"
scsi1:2.present = "TRUE"
scsi1:2.mode = "independent-persistent"
scsi1:2.filename = "K:\VMDisk\Sharedisk\votingdisk.vmdk"
scsi1:2.deviceType = "plainDisk"
scsi1:3.present = "TRUE"
scsi1:3.mode = "independent-persistent"
scsi1:3.filename = "K:\VMDisk\Sharedisk\data.vmdk"
scsi1:3.deviceType = "plainDisk"
scsi1:4.present = "TRUE"
scsi1:4.mode = "independent-persistent"
scsi1:4.filename = "K:\VMDisk\Sharedisk\backup.vmdk"
scsi1:4.deviceType = "plainDisk"
scsi1:5.present = "TRUE"
scsi1:5.mode = "independent-persistent"
scsi1:5.filename = "K:\VMDisk\Sharedisk\ocr2.vmdk"
scsi1:5.deviceType = "plainDisk"
disk.locking = "false"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.DataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
保存退出。
最後虛擬機圖大致如下：
再次提醒注意內存、硬盤和網卡配置。
配置虛擬機、安裝Linux操作系統完成。
2，配置OS
以下沒有特別說明都需要同時在兩個節點執行。
2.1 關閉防火牆、selinux(考慮到後面安裝時會碰到一些情況，所以需要執行這步驟）
關閉selinuxsetenforce 0
[root@rac1 ~]# vim /etc/selinux/config
SELINUX=disabled
關閉防火牆
service iptables stop
chkconfig iptables off
2.2 配置網絡
修改節點主機名爲rac1，rac2
hostname rac1
hostname rac2
或修改/etc/sysconfig/network
RAC1
eth0: 192.168.1.130
eth1: 10.10.17.221
RAC2
eth0: 192.168.1.140
eth1: 10.10.17.222
host文件，兩個節點都配置 Vim /etc/hosts
192.168.1.130 rac1
192.168.1.140 rac2
192.168.1.131 rac1-vip
192.168.1.141 rac2-vip
10.10.17.221 rac1-priv
10.10.17.222 rac2-priv
192.168.1.200 scan-ip
保存退出。
配置完之後互相ping看看是否連通。
2.3 配置CTSS服務、節點SSH等效
CTSS
需要把ntp服務停止和刪除配置文件及pid文件
service ntpd stop
chkconfig ntpd off
rm -rf /etc/ntpd.conf
rm -rf /var/run/ntpd.pid
查看ctss服務資源
crsctl check ctss
SSH
在grid安裝時會提供配置步驟，所以不需要手工配置。
ssh具體配置
rac1 rac2
mkdir ~/.ssh
chmod 700 ~/.ssh
ssh-keygen -t rsa
ssh-keygen -t dsa
rac1 rac2
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
測試SSH
ssh rac2
ssh rac1
2.4 配置Oracle軟件安裝用戶、組、環境變量、安裝目錄
#組
groupadd -g 1300 dba
groupadd -g 1301 oper
groupadd -g 1000 oinstall
groupadd -g 1200 asmadmin
groupadd -g 1201 asmdba
groupadd -g 1202 asmoper
#用戶
useradd -m -u 1100 -g oinstall -G asmadmin,asmdba,asmoper -s /bin/bash grid
useradd -m -u 1101 -g oinstall -G dba,oper,asmdba -s /bin/bash oracle
#用戶環境變量修改home下的 .bash_profile
ORACLE
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=RAC1 # RAC1
export ORACLE_SID=RAC2 # RAC2
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export TNS_ADMIN=$ORACLE_HOME/network/admin
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
umask 022
GRID
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=+ASM1 # RAC1
export ORACLE_SID=+ASM2 # RAC2
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/11.2.0/grid
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
umask 022
配置目錄
mkdir -p /u01/app/11.2.0/grid
mkdir -p /u01/app/grid
mkdir -p /u01/app/oracle
chown grid:oinstall /u01/app/11.2.0/grid
chown grid:oinstall /u01/app/grid
chown oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/
chown -R grid:oinstall /u01
2.5 配置系統文件
配置oracle、grid用戶的shell限制
vim /etc/security/limits.conf
添加
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
修改/etc/pam.d/login配置文件
Vim /etc/pam.d/login
添加 session required pam_limits.so
修改內核配置文件/etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 1054472192
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
net.ipv4.tcp_wmem = 262144 262144 262144
net.ipv4.tcp_rmem = 4194304 4194304 4194304
保存退出後執行 sysctl -p 立即生效。
2.6 配置共享磁盤 （在一個節點執行即可）
查看分區
ls /dev/sd*
使用fdisk進行分區，其他區按照自己的規劃劃分就可以了，例：
fdisk /dev/sdb
[root@rac1 ~]# fdisk /dev/sdb
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-1000, default 1):
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-1000, default 1000): +500M
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 2
First cylinder (502-1000, default 502):
Using default value 502
Last cylinder, +cylinders or +size{K,M,G} (502-1000, default 1000):
Using default value 1000
Command (m for help): w
The partition table has been altered!
最後配置完後查看分區
fidks -l
[root@rac1 ~]# ls /dev/sd*
/dev/sda /dev/sda1 /dev/sda2 /dev/sdb /dev/sdb1 /dev/sdc /dev/sdc1 /dev/sdd /dev/sdd1 /dev/sdd2 /dev/sde /dev/sde1 /dev/sde2 /dev/sdf /dev/sdf1
2.7 安裝Oracle grid等需要的包
binutils-2.20.51.0.2-5.11.el6 (x86_64)compat-libcap1-1.10-1 (x86_64)
compat-libstdc++-33-3.2.3-69.el6 (x86_64)

make-3.81-19.el6
sysstat-9.0.4-11.el6 (x86_64)
3，配置ASM
3.1 查看操作系統內核版本對應下載
uname -a
下載oracleasm http://www.oracle.com/technetwork/topics/linux/asmlib/index-101839.html
安裝
yum -y install kmod-oracleasm.x86_64
rpm -ivh oracleasmlib-2.0.4-1.el6.x86_64.rpm
rpm -ivh oracleasm-support-2.1.8-1.el6.x86_64.rpm
3.2 配置ASM磁盤
在兩個節點上執行
[root@rac1 oracle]# /etc/init.d/oracleasm configure
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: grid
Default group to own the driver interface []: asmdba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]:
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLib disks: [ OK ]
[root@rac1 oracle]# /etc/init.d/oracleasm scandisks
Scanning the system for Oracle ASMLib disks: [ OK ]
[root@rac1 ~]# /etc/init.d/oracleasm listdisks
VOL1
VOL2
VOL3
VOL4
VOL5
VOL6
VOL7
注：如果沒有查看到asm磁盤組需要查看之前的selinux是否有禁用。
4，安裝Oracle grid
安裝前可以執行Oracle提供的檢查環境工具
./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose
4.1 在安裝目錄下執行./runinstaller，如果出現安裝grid提示must be configured to display at least 256 colors Failed，就執行如下
root 下先執行#xhost +
su - grid
export DISPLAY=:0.0
注意在此建立SSH等效。執行setup後點test測試。如果不成功就手工配置SSH再進行測試。
這個地方忘記截圖了，就是類似這個圖。定義磁盤組名字，這裏我選擇normal冗餘，需要選擇3個VOL。
這裏是把OCR和votingdisk安裝在所選磁盤。後面還需要新建asm磁盤組來安裝其他數據文件。
這裏的software location應該是 /u01/app/11.2.0/grid
通過Oracle的系統環境檢查，安裝缺失的包和修改系統環境參數等。
安裝65%的時候可能會出現卡頓的情況，這個時候需要檢查防火牆和selinux是否關閉，詳細情況可以點擊detail查看安裝進度，如出現拷貝文件到RAC2節點的信息則正常。
根據提示執行orainstRoot.sh和root.sh腳本，先執行rac1後再執行rac2。
在執行root .sh時可能在的時候會提示出現crs-4124，這個是oracle的bug，當在redhat 6等OS下安裝11.2.0.1版本Oracle的時候會出現此錯誤。
解決如下：
在執行root.sh時，在出現Adding daemon to inittab時，需要不停地執行命令：
/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1
Running Oracle 11g root.sh script...
The following environment variables are set as:
ORACLE_OWNER= grid
ORACLE_HOME= /u01/app/11.2.0/grid
Enter the full pathname of the local bin directory: [/usr/local/bin]:
Copying dbhome to /usr/local/bin ...
Copying oraenv to /usr/local/bin ...
Copying coraenv to /usr/local/bin ...
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.sh script.
Now product-specific root actions will be performed.

備註：
在重啓節點後出現Oracle has不能通信的情況
1，[root@rac1 ~]# crsctl check crs
CRS-4639: Could not contact Oracle High Availability Services
需要在啓動時執行 /bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1。
然後再執行 crsctl check crs查看服務啓動情況。
2，如果出現以下情況，需要查看日誌提示，有一次是因爲內核參數配置值的問題導致了這個錯誤。
[root@rac1 bin]# ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
5，安裝Oracle database軟件
需要用oracle用戶安裝
su - oracle
./runInstaller
僅安裝數據庫軟件即可，這裏就根據OUI的提示安裝就可以了，最後按照提示執行相關腳本。
找時間補上截圖
6，創建ASM磁盤組
需要新建其他磁盤組來安裝數據文件等
su - grid
asmca
根據界面提示創建磁盤組。
找時間補上截圖
7，建立數據庫實例
su - oracle./runInstaller
根據OUI步驟提示選擇rac選項新建數據庫實例即可。
完成。
小結：通過實驗瞭解RAC環境的搭建和工作條件，但是這裏面還涉及到許多集羣的理論知識，需要不斷地區學習和鞏固，然後手動去實踐。
