vmware上安装oracle10g rac（一）asm+裸设备
操作系统版本RHEL5.5-64bit，oracle10g，vmware workstation6.5，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
[*]192.168.183.131node1
[*]192.168.183.132node2
[*]192.168.183.141node1-vip
[*]192.168.183.142node2-vip
[*]172.16.1.1node1-priv
[*]172.16.1.2node2-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：
[*]scsi1.present = "TRUE"
[*]scsi1.virtualDev = "lsilogic"
[*]scsi1.sharedBus = "VIRTUAL"
[*]scsi1:1.present = "TRUE"
[*]scsi1:1.mode = "independent-persistent"
[*]scsi1:1.fileName = "sharedisk.vmdk"
[*]scsi1:1.deviceType = "disk"
[*]
[*]disk.locking = "FALSE"
[*]diskLib.dataCacheMaxSize = "0"
[*]diskLib.dataCacheMaxReadAheadSize = "0"
[*]diskLib.dataCacheMinReadAheadSize = "0"
[*]diskLib.dataCachePageSize = "4096"
[*]diskLib.maxUnsyncedWrites = "0"
然后编辑node2的虚拟机配置文件，添加如下选项：
[*]scsi1.present = "TRUE"
[*]scsi1.virtualDev = "lsilogic"
[*]scsi1.sharedBus = "VIRTUAL"
[*]scsi1:1.present = "TRUE"
[*]scsi1:1.mode = "independent-persistent"
[*]scsi1:1.fileName = "D:\vmware workstation\node1\sharedisk.vmdk"
[*]scsi1:1.deviceType = "disk"
[*]
[*]disk.locking = "FALSE"
[*]diskLib.dataCacheMaxSize = "0"
[*]diskLib.dataCacheMaxReadAheadSize = "0"
[*]diskLib.dataCacheMinReadAheadSize = "0"
[*]diskLib.dataCachePageSize = "4096"
[*]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
http://lymrg.blog./1551327/754136
在两个节点上面创建对应文件夹
[*]# ll
[*]总计 12
[*]drwxr-xr-x 2 oracle oinstall 4096 03-08 16:08 oraasm
[*]drwxr-xr-x 2 oracle oinstall 4096 03-08 16:08 orabase
[*]drwxr-xr-x 2 root oinstall 4096 03-08 16:08 oracrs
这里oracle的变量设置做下更改
[*]PATH=$PATH:$HOME/bin
[*]export ORACLE_BASE=/home/oracle/orabase
[*]export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
[*]export ORA_CRS_HOME=/home/oracle/oracrs/product/10.2.0/crs
[*]export ORA_ASM_HOME=/home/oracle/oraasm/product/10.2.0/asm
[*]export ORACLE_SID=orcl1 PATH=$PATH:$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:$ORA_ASM_HOME/bin
[*]export PATH
4.配置两台机器无密码访问,这里的配置要在两个节点上面进行
（1）以oracle 用户登录
（2）在oracle 用户的主目录内创建.ssh 目录并设置正确的权限
[*]$ mkdir ~/.ssh
[*]$ chmod 700 ~/.ssh
[*]$ ssh-keygen -t rsa
[*]Generating public/private rsa key pair.
[*]Enter file in which to save the key (/home/oracle/.ssh/id_rsa):
[*]Enter passphrase (empty for no passphrase):
[*]Enter same passphrase again:
[*]Your identification has been saved in /home/oracle/.ssh/id_rsa.
[*]Your public key has been saved in /home/oracle/.ssh/id_rsa.pub.
[*]The key fingerprint is:
[*]17:e4:7c:79:8d:a0:00:3b:d9:f7:7a:56:f3:ac:54:4d oracle@node1
[*]
[*] $ cd ~/.ssh
[*]$ ssh node1 cat /home/oracle/.ssh/id_rsa.pub >>
[*]authorized_keys
[*]$ ssh node2 cat /home/oracle/.ssh/id_dsa.pub
[*]>>authorized_keys
[*]$ scp authorized_keys node2:/home/oracle/.ssh/
[*]$ chmod 600 ~/.ssh/authorized_keys
完成后，在node1 上执行：
[*]$ ssh node1 date
[*]$ 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。
5.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
[*]fdisk -l
[*]Disk /dev/sdb: 9663 MB, 9663676416 bytes
[*]255 heads, 63 sectors/track, 1174 cylinders
[*]Units = cylinders of 16065 * 512 = 8225280 bytes
[*]
[*] Device Boot Start End Blocks IdSystem
[*]/dev/sdb1 1 63 506016 83Linux
[*]/dev/sdb2 64 126 506047+83Linux
[*]/dev/sdb3 127 1174 8418060 5Extended
[*]/dev/sdb5 127 189 506016 83Linux
[*]/dev/sdb6 190 252 506016 83Linux
[*]/dev/sdb7 253 315 506016 83Linux
[*]/dev/sdb8 316 1174 6899886 83Linux
配置裸设备
[*]vi /etc/udev/rules.d/60-raw.rules
[*]ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"
[*]ACTION=="add", KERNEL=="sdb2", RUN+="/bin/raw /dev/raw/raw2 %N"
[*]ACTION=="add", KERNEL=="sdb5", RUN+="/bin/raw /dev/raw/raw3 %N"
[*]ACTION=="add", KERNEL=="sdb6", RUN+="/bin/raw /dev/raw/raw4 %N"
[*]ACTION=="add", KERNEL=="sdb7", RUN+="/bin/raw /dev/raw/raw5 %N"
[*]ACTION=="add", KERNEL=="sdb8", RUN+="/bin/raw /dev/raw/raw6 %N"
[*]
[*]KERNEL=="raw1", OWNER="root", GROUP="oinstall", MODE="660"
[*]KERNEL=="raw2", OWNER="root", GROUP="oinstall", MODE="660"
[*]KERNEL=="raw3", OWNER="root", GROUP="oinstall", MODE="660"
[*]KERNEL=="raw4", OWNER="root", GROUP="oinstall", MODE="660"
[*]KERNEL=="raw5", OWNER="root", GROUP="oinstall", MODE="660"
[*]KERNEL=="raw6", OWNER="oracle", GROUP="oinstall", MODE="664"
[*]
[*]# start_udev
[*]启动 udev： [确定]
[*]# ll /dev/raw/raw*
[*]crw-rw---- 1 root oinstall 162, 1 03-11 22:43 /dev/raw/raw1
[*]crw-rw---- 1 root oinstall 162, 2 03-11 22:43 /dev/raw/raw2
[*]crw-rw---- 1 root oinstall 162, 3 03-11 22:43 /dev/raw/raw3
[*]crw-rw---- 1 root oinstall 162, 4 03-11 22:43 /dev/raw/raw4
[*]crw-rw---- 1 root oinstall 162, 5 03-11 22:43 /dev/raw/raw5
[*]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
6.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
[*]rpm -ivh oracleasm-support-2.1.7-1.el5.x86_64.rpm
[*]rpm -ivh oracleasm-2.6.18-194.el5-2.0.5-1.el5.x86_64.rpm
[*]rpm -ivh oracleasmlib-2.0.4-1.el5.x86_64.rpm
在两个节点上面执行/etc/init.d/oracleasm configure
分别输入oracle,dba,y,y
在node1上面配置ASM
[*]#/etc/init.d/oracleasm createdisk VOL1 /dev/sdb8
[*]#/etc/init.d/oracleasm scandisks
[*]#/etc/init.d/oracleasm listdisks
[*]VOL1
在node2上面执行扫描（不需要配置）
[*]/etc/init.d/oracleasm scandisks
[*]/etc/init.d/oracleasm listdisks
[*]VOL1
7.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IP4）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
[*]# /home/oracle/orabase/oraInventory/orainstRoot.sh
[*]
[*]Changing permissions of /home/oracle/orabase/oraInventory to 770.
[*]
[*]Changing groupname of /home/oracle/orabase/oraInventory to oinstall.
[*]
[*]The execution of the script is complete
在节点node2上面执行
[*]# /home/oracle/orabase/oraInventory/orainstRoot.sh
[*]
[*]Changing permissions of /home/oracle/orabase/oraInventory to 770.
[*]
[*]Changing groupname of /home/oracle/orabase/oraInventory to oinstall.
[*]
[*]The execution of the script is complete
在节点node1上面执行
[*]# /home/oracle/oracrs/product/10.2.0/crs/root.sh
在节点node2上面执行
[*]# /home/oracle/oracrs/product/10.2.0/crs/root.sh
安装结束，查看节点状态
[*]# ./crs_stat -t
[*]Name Type Target State Host
