一、ASM安装准备条件

1、ASM支持存储类型

本地祼设备（本地的磁盘和分区）
网络附加存储(NAS)
存储区域网络(SAN)

2、ASM使用本地裸设备，要点:
已经被挂载到操作系统上或者已经做了分区
映射裸设备为文件名
设置正确的权限（针对grid用户和asmadmin组，权限为660）

二、ORACLE单实例-ASM实验

1、操作系统环境准备

设置主机名

[root@oracle ~]# hostnamectl set-hostname oracle
[root@oracle ~]# hostname  && hostname  -i
oracle
192.168.31.52
[root@oracle ~]#

关闭selinuix

[root@oracle ~]# vi   /etc/selinux/config

关闭防火墙

systemctl stop firewalld.service
systemctl disable firewalld.service
systemctl status firewalld.service
