操作系统版本RHEL5.5-64bit，oracle10g，vmwareworkstation6.5，clusterware10.0.2版本的
两台虚拟机双网卡，本地磁盘40G，共享磁盘9G，共享磁盘选择立即分配所有磁盘空间，两台虚拟机内存都是1.5G
1.配置hosts文件可以让两台虚拟机可以通过名称互相解析
1.192.168.183.131 node1
2.192.168.183.132 node2
3.192.168.183.141 node1-vip
4.192.168.183.142 node2-vip
5.172.16.1.1 node1-priv
6.172.16.1.2 node2-priv
2.给虚拟机添加共享磁盘，首先在node1上面添加一块共享磁盘，选择分配全部的空间（虚拟机下一定要这么设置，否则会导致共享存储配置不成功）
node1添加共享磁盘（sharedisk.vmdk）-开机-关机，然后编辑node1的虚拟机配置文件，添加如下选项：
1.scsi1.present = "TRUE"
2.scsi1.virtualDev = "lsilogic"
3.scsi1.sharedBus = "VIRTUAL"
4.scsi1:
1.present = "TRUE"
5.scsi1:
1.mode = "independent-persistent"
6.scsi1:
1.fileName = "sharedisk.vmdk"
7.scsi1:
1.deviceType = "disk"
8.
9.disk.locking = "FALSE"
10.diskLib.dataCacheMaxSize = "0"
11.diskLib.dataCacheMaxReadAheadSize = "0"
12.diskLib.dataCacheMinReadAheadSize = "0"
13.diskLib.dataCachePageSize = "4096"
14.diskLib.maxUnsyncedWrites = "0"
然后编辑node2的虚拟机配置文件，添加如下选项：
1.scsi1.present = "TRUE"
2.scsi1.virtualDev = "lsilogic"
3.scsi1.sharedBus = "VIRTUAL"
4.scsi1:
1.present = "TRUE"
5.scsi1:
1.mode = "independent-persistent"
6.scsi1:
1.fileName = "D:
\vmware workstation\node1\sharedisk.vmdk"
7.scsi1:
1.deviceType = "disk"
8.
9.disk.locking = "FALSE"
10.diskLib.dataCacheMaxSize = "0"
11.diskLib.dataCacheMaxReadAheadSize = "0"
12.diskLib.dataCacheMinReadAheadSize = "0"
13.diskLib.dataCachePageSize = "4096"
14.diskLib.maxUnsyncedWrites = "0"
关闭虚拟机软件，然后分别打开两台虚拟机的电源，共享磁盘配置完毕
3.oracle安装环境准备
这里参照我以前的文章，oracle安装前期准备工作的设置
在两个节点上面创建对应文件夹
1.[root@node1 oracle]# ll
2.总计 12
3.drwxr-xr-x 2 oracle oinstall 4096 03-08 16:
08 oraasm
4.drwxr-xr-x 2 oracle oinstall 4096 03-08 16:
08 orabase
5.drwxr-xr-x 2 root oinstall 4096 03-08 16:
08 oracrs
这里oracle的变量设置做下更改
1.PATH=$PATH:
$HOME/bin
2.export ORACLE_BASE=/home/oracle/orabase
3.export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
4.export ORA_CRS_HOME=/home/oracle/oracrs/product/10.2.0/crs
5.export ORA_ASM_HOME=/home/oracle/oraasm/product/10.2.0/asm
6.export ORACLE_SID=orcl1 PATH=$PATH:
$ORACLE_HOME/bin:
$ORA_CRS_HOME/bin:
$ORA_ASM_HOME/bin
7.export PATH
4.建立hangcheck模块加载（在两个节点上面操作）
1.[root@node1 ~]# find /lib/modules -name "hangcheck-timer.ko"
2.[root@node1 ~]# vi /etc/modprobe.conf
3.options hangcheck-timer hangcheck_tick=30 hangcheck_margin=180
4.[root@node1 ~]# vi /etc/rc.local
5./sbin/modprobe hangcheck_timer
6.启动 /sbin/modprobe hangcheck_timer
7.查看启动是否成功
8.[root@node1 ~]# grep hangcheck /var/log/messages|tail -2
9.Mar 12 15:
25:
47 node1 kernel:
Hangcheck:
starting hangcheck timer 0.9.0 （tick is 30 seconds, margin is 180 seconds）.
5.配置两台机器无密码访问,这里的配置要在两个节点上面进行
（1）以oracle用户登录
（2）在oracle用户的主目录内创建.ssh目录并设置正确的权限
1.[oracle@node1 ~]$ mkdir ~/.ssh
2.[oracle@node1 ~]$ chmod 700 ~/.ssh
3.[oracle@node1 ~]$ ssh-keygen -t rsa
4.Generating public/private rsa key pair.
5.Enter file in which to save the key （/home/oracle/.ssh/id_rsa）:
6.Enter passphrase （empty for no passphrase）:
7.Enter same passphrase again:
8.Your identification has been saved in /home/oracle/.ssh/id_rsa.
9.Your public key has been saved in /home/oracle/.ssh/id_rsa.pub.
10.The key fingerprint is:
11.17:
e4:
7c:
79:
8d:
a0:
00:
3b:
d9:
f7:
7a:
56:
f3:
ac:
54:
4d oracle@node1
12.
13.[oracle@node1 ~] $ cd ~/.ssh
14.[oracle@node1 .ssh]$ ssh node1 cat /home/oracle/.ssh/id_rsa.pub >>
15.authorized_keys
16.[oracle@node1 .ssh]$ ssh node2 cat /home/oracle/.ssh/id_dsa.pub
17.>>authorized_keys
18.[oracle@node1 .ssh]$ scp authorized_keys node2:
/home/oracle/.ssh/
19.[oracle@node1 .ssh]$ chmod 600 ~/.ssh/authorized_keys
完成后，在node1上执行：
1.[oracle@node1 ~]$ ssh node1 date
2.[oracle@node1 ~]$ ssh node2 date
如果不需要输入密码就出现系统日期，说明SSH配置成功。
6.磁盘规划
这里我把共享磁盘分成6个区，sdb1和sdb2配制成裸设备，作为OCR镜像，sdb5,6,7也配置成裸设备，作votedisk镜像，sdb配置成ASM用来存放数据库
1.fdisk -l
2.Disk /dev/sdb:
9663 MB, 9663676416 bytes
3.255 heads, 63 sectors/track, 1174 cylinders
4.Units = cylinders of 16065 * 512 = 8225280 bytes
5.
6. Device Boot Start End Blocks Id System
7./dev/sdb1 1 63 506016 83 Linux
8./dev/sdb2 64 126 506047+ 83 Linux
9./dev/sdb3 127 1174 8418060 5 Extended
10./dev/sdb5 127 189 506016 83 Linux
11./dev/sdb6 190 252 506016 83 Linux
12./dev/sdb7 253 315 506016 83 Linux
13./dev/sdb8 316 1174 6899886 83 Linux
配置裸设备
1.vi /etc/udev/rules.d/60-raw.rules
2.ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"
3.ACTION=="add", KERNEL=="sdb2", RUN+="/bin/raw /dev/raw/raw2 %N"
4.ACTION=="add", KERNEL=="sdb5", RUN+="/bin/raw /dev/raw/raw3 %N"
5.ACTION=="add", KERNEL=="sdb6", RUN+="/bin/raw /dev/raw/raw4 %N"
6.ACTION=="add", KERNEL=="sdb7", RUN+="/bin/raw /dev/raw/raw5 %N"
7.ACTION=="add", KERNEL=="sdb8", RUN+="/bin/raw /dev/raw/raw6 %N"
8.
9.KERNEL=="raw1", OWNER="root", GROUP="oinstall", MODE="660"
10.KERNEL=="raw2", OWNER="root", GROUP="oinstall", MODE="660"
11.KERNEL=="raw3", OWNER="root", GROUP="oinstall", MODE="660"
12.KERNEL=="raw4", OWNER="root", GROUP="oinstall", MODE="660"
13.KERNEL=="raw5", OWNER="root", GROUP="oinstall", MODE="660"
14.KERNEL=="raw6", OWNER="oracle", GROUP="oinstall", MODE="664"
15.
16.[root@node1 ~]# start_udev
17.启动 udev：
[确定]
18.[root@node1 ~]# ll /dev/raw/raw*
19.crw-rw---- 1 root oinstall 162, 1 03-11 22:
43 /dev/raw/raw1
20.crw-rw---- 1 root oinstall 162, 2 03-11 22:
43 /dev/raw/raw2
21.crw-rw---- 1 root oinstall 162, 3 03-11 22:
43 /dev/raw/raw3
22.crw-rw---- 1 root oinstall 162, 4 03-11 22:
43 /dev/raw/raw4
23.crw-rw---- 1 root oinstall 162, 5 03-11 22:
43 /dev/raw/raw5
24.crw-rw-r-- 1 oracle oinstall 162, 6 03-11 22:
43 /dev/raw/raw6
在node2上面执行partprobe,然后同样建立裸设备
7.在两个节点上面安装,注意要下载和自己内核版本对应的包
1.rpm -ivh oracleasm-support-2.1.7-1.el5.x86_64.rpm
2.rpm -ivh oracleasm-2.6.18-194.el5-2.0.5-1.el5.x86_64.rpm
3.rpm -ivh oracleasmlib-2.0.4-1.el5.x86_64.rpm
在两个节点上面执行/etc/init.d/oracleasmconfigure
分别输入oracle,dba,y,y
在node1上面配置ASM
1.[root@node1 ~]#/etc/init.d/oracleasm createdisk VOL1 /dev/sdb8
2.[root@node1 ~]#/etc/init.d/oracleasm scandisks
3.[root@node1 ~]#/etc/init.d/oracleasm listdisks
4.VOL1
在node2上面执行扫描（不需要配置）
1./etc/init.d/oracleasm scandisks
2./etc/init.d/oracleasm listdisks
3.VOL1
8.开启安装进程，在两个节点上面以root用户身份运行
然后切换到oracle用户，开始安装clusterware
1）选择CRS的安装目录
2）两个集群节点的配置
3）选择eth0网卡为公网IP
4）配置OCR存储位置
5）配置votedisk存储位置
6）安装
7）执行最后的安装脚本
在节点node1上面执行
1.[root@node1 oracrs]# /home/oracle/orabase/oraInventory/orainstRoot.sh
2.
3.Changing permissions of /home/oracle/orabase/oraInventory to 770.
4.
5.Changing groupname of /home/oracle/orabase/oraInventory to oinstall.
6.
7.The execution of the script is complete
在节点node2上面执行
1.[root@node2 oracrs]# /home/oracle/orabase/oraInventory/orainstRoot.sh
2.
3.Changing permissions of /home/oracle/orabase/oraInventory to 770.
4.
5.Changing groupname of /home/oracle/orabase/oraInventory to oinstall.
6.
7.The execution of the script is complete
在节点node1上面执行
1.[root@node1 oracle]# /home/oracle/oracrs/product/10.2.0/crs/root.sh
在节点node2上面执行
1.[root@node2 oracle]# /home/oracle/oracrs/product/10.2.0/crs/root.sh
安装结束，查看节点状态
1.[root@node2 bin]# ./crs_stat -t
