基于CentOS与VmwareStation10搭建Oracle11G RAC 64集群环境：3.安装Oracle RAC-3.1.安装并配置ASM驱动
3.1.安装并配置ASM驱动
3.3.1.检查内核
[root@linuxrac2 etc]# uname -r 2.6.18-164.el5 |
下载以下rpm包(注意rpm包版本和Linux内核版本一致):
Oracle ASMlib下载地址:http://www.oracle.com/technetwork/server-storage/linux/downloads/rhel5-084877.html

3.1.3. 初始化 asmlib(在所有节点执行)
启动oracle asmlib: |
[root@linuxrac1 etc]# /etc/init.d/oracleasm start Initializing the Oracle ASMLib driver: [ OK ] Scanning the system for Oracle ASMLib disks: [ OK ] |
启用asmlib： |
[root@linuxrac1 etc]# /etc/init.d/oracleasm enable Writing Oracle ASM library driver configuration: done Initializing the Oracle ASMLib driver: [ OK ] Scanning the system for Oracle ASMLib disks: [ OK ] |
以root用户配置节点linuxrac1 |
[root@linuxrac1 /]# /etc/init.d/oracleasm configure -i 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 []: oinstall Start Oracle ASM library driver on boot (y/n) [n]: y Scan for Oracle ASM disks on boot (y/n) [y]: y Writing Oracle ASM library driver configuration: done Initializing the Oracle ASMLib driver: [ OK ] Scanning the system for Oracle ASMLib disks: [ OK ] [root@linuxrac1 /]# /usr/sbin/oracleasm init Creating /dev/oracleasm mount point: /dev/oracleasm Loading module "oracleasm": oracleasm Mounting ASMlib driver filesystem: /dev/oracleasm |

3.1.4. 磁盘分区(节点1执行)
1.查询磁盘 |
[root@linuxrac1 dev]# fdisk -l
Disk /dev/sda: 32.2 GB, 32212254720 bytes 255 heads, 63 sectors/track, 3916 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0005464c
Device Boot Start End Blocks Id System /dev/sda1 * 1 39 307200 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 39 545 4063232 82 Linux swap / Solaris Partition 2 does not end on cylinder boundary. /dev/sda3 545 3917 27085824 83 Linux
Disk /dev/sdb: 4294 MB, 4294967296 bytes 255 heads, 63 sectors/track, 522 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000
Disk /dev/sde: 5368 MB, 5368709120 bytes 255 heads, 63 sectors/track, 652 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000
Disk /dev/sdc: 21.5 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000
Disk /dev/sdd: 21.5 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 |
2.磁盘分区，注意分区的Last cylinder的值不能选错，选择default 值就好。 |
[root@linuxrac1 /]# fdisk /dev/sdb Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel with disk identifier 0x52362e93. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won‘t be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It‘s strongly recommended to switch off the mode (command ‘c‘) and change display units to sectors (command ‘u‘).
Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-522, default 1): 1 Last cylinder, +cylinders or +size{K,M,G} (1-522, default 522): 522
Command (m for help): w The partition table has been altered!
Calling ioctl() to re-read partition table. Syncing disks. |
/dev/sdc,/dev/sdd，/dev/sde执行相同操作。
3.1.5.创建 asm 磁盘,在节点1执行
1.使用oracleasm createdisk 创建ASM磁盘label:在一个节点执行即可 |
[root@linuxrac1 /]# /etc/init.d/oracleasm createdisk OCR_VOTE /dev/sdb1 Marking disk "OCR_VOTE" as an ASM disk: [ OK ] [root@linuxrac1 /]# oracleasm createdisk OCR_VOTE /dev/sdb1 Device "/dev/sdb1" is already labeled for ASM disk "OCR_VOTE" [root@linuxrac1 /]# oracleasm createdisk DATA /dev/sdc1 Writing disk header: done Instantiating disk: done [root@linuxrac1 /]# oracleasm createdisk DATA2 /dev/sdd1 Writing disk header: done Instantiating disk: done [root@linuxrac1 /]# oracleasm createdisk FRA /dev/sde1 Writing disk header: done Instantiating disk: done [root@linuxrac1 /]# oracleasm scandisks Reloading disk partitions: done Cleaning any stale ASM disks... Scanning system for ASM disks... |
2.查看创建后的ASM磁盘 |
[root@linuxrac1 /]# oracleasm listdisks DATA DATA2 FRA OCR_VOTE |
3.检查磁盘是否已挂载在oracleasm文件系统： |
[root@linuxrac1 /]# ls -l /dev/oracleasm/disks total 0 brw-rw---- 1 grid oinstall 8, 33 Sep 24 18:29 DATA brw-rw---- 1 grid oinstall 8, 49 Sep 24 18:29 DATA2 brw-rw---- 1 grid oinstall 8, 65 Sep 24 18:29 FRA brw-rw---- 1 grid oinstall 8, 17 Sep 24 18:29 OCR_VOTE |
3.1.6. 节点2扫描识别ASM磁盘
节点2扫描识别ASM磁盘 |
root@linuxrac2 etc]# oracleasm scandisks Reloading disk partitions: done Cleaning any stale ASM disks... Scanning system for ASM disks... Instantiating disk "OCR_VOTE" Instantiating disk "DATA" Instantiating disk "DATA2" Instantiating disk "FRA" |
