Oracle版本：Oracle 11g
1、確定自己的Linux版本：
[root@localhost ~]#uname -r
2.6.32-431.el6.x86_64
2.6.32-431.el6.x86_64，即Linux 6
2、安裝Oracleasm Kernel：
[root@localhost ~]# yum install kmod-oracleasm
3、下載兩個安裝包：oracleasmlib和oracleasm-support
[root@localhost ~]#wget http://oss.oracle.com/projects/oracleasm-support/dist/files/RPMS/rhel6/amd64/2.1.8/oracleasm-support-2.1.8-1.el6.x86_64.rpm
[root@localhost ~]#wget http://download.oracle.com/otn_software/asmlib/oracleasmlib-2.0.4-1.el6.x86_64.rpm
4、安裝這兩個包：
[root@localhost ~]#rpm -ivh oracleasm*
5、配置：
[root@localhost ~]#su oracle
[root@localhost ~]#/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) [n]: y
Fix permissions of Oracle ASM disks on boot (y/n) [y]: y

如果想關閉這個ASM磁盤，可以這樣配置：
[root@ca-test1 /]# /etc/init.d/oracleasm disable
Writing Oracle ASM library driver configuration [ OK ]
Unmounting ASMlib driver filesystem [ OK ]
Unloading module "oracleasm" [ OK ]
[root@ca-test1 /]# /etc/init.d/oracleasm enable

Scanning system for ASM disks [ OK ]
6、為ASM准備一塊硬盤空間：
首先可以使用fdisk -l命令查看分區，
我這里為ASM准備了一塊還沒有分區的硬盤，
使用fdisk -l命令看到這塊硬盤叫sdc，然后我們開始給這塊硬盤分區：
[root@localhost ~]# fdisk /dev/sdc
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x3c1761b2.
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): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition（創建新分區）
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
Command (m for help): n
Command action
e extended
p primary partition (1-4)
因為ASM要求必須是主分區或邏輯分區所以只能選p：
Command (m for help): p
Partition number (1-4): 2
First cylinder (1-121601, default 1):
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-121601, default 121601):
Using default value 121601
再次執行fdisk -l命令查看分區：
Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 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: 0x881f3ea8
Device Boot Start End Blocks Id System
/dev/sdc2 1 121601 976760001 83 Linux
7、將硬盤空間分配給ASM：
查看磁盤組：
[root@ca-test1 /]# /etc/init.d/oracleasm listdisks
VOL1
新建一個磁盤組VOL2並分配給ASM：
[root@ca-test1 /]# /etc/init.d/oracleasm createdisk VOL2 /dev/sdc2
Creating Oracle ASM disk "VOL2" [ OK ]
