VMware上安装Oracle 10g RAC-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
  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"
  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"
  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 http://lymrg.blog.51cto.com/1551327/754136 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 409603-0816:08 oraasm
  4. drwxr-xr-x 2 oracle oinstall 409603-0816:08 orabase
  5. drwxr-xr-x 2 root oinstall 409603-0816:08 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:$ORA_ASM_HOME/bin
  7. export PATH
4.建立hangcheck模块加载（在两个节点上面操作）  
  1. [root@node1 ~]# find /lib/modules -name "hangcheck-timer.ko"
  2. [root@node1 ~]# vi /etc/modprobe.conf
  3. options hangcheck-timer hangcheck_tick=30 hangcheck_margin=180
  4. [root@node1 ~]# vi /etc/rc.local
  5. /sbin/modprobe hangcheck_timer
  6. 启动 /sbin/modprobe hangcheck_timer
  7. 查看启动是否成功
  8. [root@node1 ~]# grep hangcheck /var/log/messages|tail -2
  9. Mar 1215:25:47 node1 kernel: Hangcheck: starting hangcheck timer 0.9.0 (tick is30 seconds, margin is180 seconds).
  5.配置两台机器无密码访问,这里的配置要在两个节点上面进行 （1）以oracle 用户登录 （2）在oracle 用户的主目录内创建.ssh 目录并设置正确的权限
  1. [oracle@node1 ~]$ 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
  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
  6. Device Boot Start End Blocks Id System
  7. /dev/sdb1 16350601683 Linux
  8. /dev/sdb2 64126506047+ 83 Linux
  9. /dev/sdb3 127117484180605 Extended
  10. /dev/sdb5 12718950601683 Linux
  11. /dev/sdb6 19025250601683 Linux
  12. /dev/sdb7 25331550601683 Linux
  13. /dev/sdb8 3161174689988683 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"
  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"
  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, 103-1122:43 /dev/raw/raw1
  20. crw-rw---- 1 root oinstall 162, 203-1122:43 /dev/raw/raw2
  21. crw-rw---- 1 root oinstall 162, 303-1122:43 /dev/raw/raw3
  22. crw-rw---- 1 root oinstall 162, 403-1122:43 /dev/raw/raw4
  23. crw-rw---- 1 root oinstall 162, 503-1122:43 /dev/raw/raw5
  24. crw-rw-r-- 1 oracle oinstall 162, 603-1122:43 /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/oracleasm configure 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
  3. Changing permissions of /home/oracle/orabase/oraInventory to 770.
  5. Changing groupname of /home/oracle/orabase/oraInventory to oinstall.
  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
  3. Changing permissions of /home/oracle/orabase/oraInventory to 770.
  5. Changing groupname of /home/oracle/orabase/oraInventory to oinstall.
  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
  2. Name Type Target State Host
