Study--Oracle-07-ASM自动存储管理（二）
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
