# 您需要知道的
- 您需要熟悉如何去搭建 Linux 操作系统，可参考 OS-INS 类相关文档完成此操作
- 您需要熟悉如何在 Linux 操作系统上安装 Oracle 数据库，可参考 ORACLE-INS-FS 类相关文档完成此操作
- 您需要熟悉如何在 Linux 操作系统上安装单实例 ASM 环境，可参考 ORACLE-INS-ASM 相关文档完成此操作
- 本文不适合零基础，如果可以，请按照上述三条进行逐步学习
- 本文采用 VMWare Workstation 15.5 虚拟机/Oracle 19c/Oracle Linux 7.8 环境进行集群双节点搭建
- 如果学习 RAC，配置共享磁盘强烈建议使用 VirtualBox 虚拟机
- 文中出现的系统规划、网络规划及存储规划作为实验学习使用，生产环境需根据实际情况进行规划

# 1 规划
## 1.1 系统规划

## 6.3 节点2虚拟机添加代码段
```sql
# 节点二虚拟机配置文件中添加以下代码段，避免同时开启锁定磁盘

disk.locking = "FALSE" 
diskLib.dataCacheMaxSize= "0" 
scsi1.sharedBus ="virtual"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.DataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
disk.EnableUUID = "TRUE"
```
## 6.4 节点1分区
```sql
fdisk /dev/sdd
fdisk /dev/sde
fdisk /dev/sdf
fdisk /dev/sdg
```
## 6.5 节点1确认SCSI标识符
- 通过命令 /usr/lib/udev/scsi_id -g -u -d 分区名 确认标识符，最终对应关系如下

## 6.6 节点1编辑UDEV规则文件
- 创建文件 `vim /etc/udev/rules.d/99-oracle-asmdevices.rules`，按以下格式编辑条目，替换 `RESULT` 对应的 `SCSI` 标识符

```sql
KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="36000c29c627c4e18666e2ba340715dc9", SYMLINK+="oasm/asm-ocr1", OWNER="grid", GROUP="asmadmin", MODE="0660"

```

- 执行 partprobe 识别

```sql
/sbin/partprobe /dev/sdd1
/sbin/partprobe /dev/sde1
/sbin/partprobe /dev/sdf1
/sbin/partprobe /dev/sdg1
```
- 查看磁盘

```sql
请确保所有链接磁盘均可见，并具有对应的正确权限，否则，在进行下一步之前请解决该问题。
[root@racnode1 ~]# ls -lathr /dev/oasm/*
lrwxrwxrwx 1 root root 7 Oct 10 10:26 /dev/oasm/asm-ocr1 -> ../sdd1

```
## 6.7 拷贝节点1 UDEV文件至节点2
```sql
