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 fo本文来源gaodai$ma#com搞$$代**码网$r Oracle ASMLib disks: [ OK ]
