ASM是Oracle针对rac发布的存储产品,虽然是针对集群环境设置的,在单机环境上我们也可以采用ASM实例来管理磁盘。

(一)安装配置

一、确认linux内核版本

[root@sigleNode ~]# uname -r

2.6.18-53.el5xen

需要根据上面内核版本去Oracle官网上下载指定的ASMLib包,本地下载:

下载在Linux公社的1号FTP服务器里,下载地址:

二、安装asmlib包

[root@sigleNodeasm]# rpm -ivh *.rpm

三、添加两块硬盘,,然后分区,不需要格式化

[root@sigleNodedev]# fdisk /dev/hda

Command (m for help):n

Command action

e extended

p primary partition (1-4)

p

Partition number (1-4):1

First cylinder (1-261, default 1):1

Last cylinder or +size or +sizeM or +sizeK (1-261, default 261):261

Command (m for help):w

The partition table has been altered!

Calling ioctl() to re-read partition table.

Syncing disks.

执行同样命令对/dev/hdb进行分区即可

分区之后的结果如下:

[root@sigleNode ~]# fdisk -l

Disk /dev/hda: 2147 MB, 2147483648 bytes

16 heads, 63 sectors/track, 4161 cylinders

Units = cylinders of 1008 * 512 = 516096 bytes

Device Boot Start End Blocks Id System

/dev/hda1 1 4161 2097112+ 83 Linux

Disk /dev/hdb: 2147 MB, 2147483648 bytes

16 heads, 63 sectors/track, 4161 cylinders

Units = cylinders of 1008 * 512 = 516096 bytes

Device Boot Start End Blocks Id System

/dev/hdb1 1 4161 2097112+ 83 Linux

四、配置ASM环境

[root@sigleNode~]# /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 without typing an

answer will keep that current value. Ctrl-C will abort.

Default user to own the driver interface [ ]:oracle

Default group to own the driver interface [ ]:dba

Start Oracle ASM library driver on boot (y/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 ]
