centos6.5桌面2.6.32
yum install kmod-oracleasm其实就是安装三个包，内核驱动也就是上面的包是基础，在官方网站可以下载oracleasm-support、oracleasmlib这两个包。
http://www.oracle.com/technetwork/server-storage/linux/downloads/index.html这个页面最下面For Database Administrators ASMLib: Linux Drivers for Automatic Storage Managementhttp://www.oracle.com/technetwork/server-storage/linux/asmlib/index-101839.html
http://oss.oracle.com/projects/oracleasm-support/dist/files/RPMS/rhel6/amd64/2.1.8/oracleasm-support-2.1.8-1.el6.x86_64.rpmhttp://download.oracle.com/otn_software/asmlib/oracleasmlib-2.0.4-1.el6.x86_64.rpm
点开页面的上方可以看到Library and Tools
这里可以下载oracleasm-support、oracleasmlib下面接着是Drivers for kernel N多版本的oracleasm安装包
使用uname -a判断系统内核的版本号使用root用户安装，这三个包之间有依赖关系，安装顺序如下：
rpm -ivh oracleasm-supportrpm -ivh oracleasmrpm -ivh oracleasmlibroot用户使用以下命令配置ASM：
/etc/init.d/oracleasm configure注意：直接使用oracleasm configure是不能配置ASM的！
[root@oracle ~]# /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 isloaded on boot and what permissions it will have. The current valueswill be shown in brackets ('[]'). Hitting <ENTER> without typing ananswer will keep that current value. Ctrl-C will abort.Default user to own the driver interface []: oracle

[root@oracle log]# usermod -G dba oracle[root@oracle log]# id oracleuid=500(oracle) gid=500(oracle) groups=500(oracle),501(dba)事先还要准备空分区或磁盘供oracleasm调用。只有先创建相关用户后，下面的创建磁盘才会ok
[root@oracle log]# /etc/init.d/oracleasm createdisk hh /dev/sdb1
Marking disk "hh" as an ASM disk: [ OK ]报错日志可以看下面这个文件。
[root@oracle log]# cat /var/log/oracleasm
准备空盘或分区
fdisk /dev/sdb,分两个区
