部署 Oracle Grid Infrastructure 和 Oracle RAC

部署 Oracle Grid Infrastructure 和 Oracle RAC 数据库涉及配置 Oracle Automatic Storage Management (Oracle ASM) 磁盘、在无提示或 GUI 模式下安装 Oracle Grid Infrastructure 、重新引导 Oracle Clusterware 、安装 Oracle RAC 数据库软件、创建 Oracle RAC 数据库以及验证您的部署。

以下步骤介绍了如何在 Private Cloud Appliance 系统中部署 Oracle Grid Infrastructure 和 Oracle RAC 。

使用 asmcmd 或 asmlib 为磁盘设置标签。例如：GI_HOME/bin/asmcmd afd_label diskgroup_name disk_with_full_path --init。有关详细信息，请参阅 Oracle Grid Infrastructure Installation Guide 。
```
/u01/app/21.0.0/grid/bin/asmcmd afd_label OCR /dev/sdc ––init
```
创建响应文件。可以使用 GI_Home/install/response 中的响应文件样例并添加变量值。
在无提示模式下安装 Oracle Grid Infrastructure 。例如：GI_HOME/gridSetup.sh -silent -responseFile responsefile_name_with_full_path.
```
/u01/app/21.0.0/grid/gridSetup.sh -silent -responseFile /home/oracle/gridsetup.rsp
```
设置环境变量 HAIP_UNSUPPORTED=TRUE。
Oracle Private Cloud Appliance X9-2 机架使用 IP 范围 169.254.0.0/16 进行与引导卷和块存储卷、实例元数据和其他服务的 iSCSI 连接。这会影响专用网络使用的 HAIP 通信，导致 Oracle Grid Infrastructure 安装失败。要成功进行 HAIP 通信，需要设置此环境变量。
```
$ export HAIP_UNSUPPORTED=TRUE
```
在每个节点上执行 ./root.sh 命令。
```
$ ./root.sh
```
使用群集验证实用程序 Cluvfy 验证安装后。例如：GI_HOME/bin/cluvfy -post crsinst -n node1, node2。
```
u01/app/21.0.0/grid/bin/cluvfy -post crsinst -n racvm1,racvm2
```

使用 crsctl 命令检查 Oracle Clusterware 资源。

[oracle@racvm1 ~]$ crsctl stat res -t

[oracle@racvm1 ~]$

使用 runInstaller 作为 RDBMS 用户以无提示模式或 GUI 模式安装 Oracle RAC 数据库软件。有关更多详细信息，请参阅 Oracle Real Application Clusters Installation Guide 。
无提示模式示例：RDBMS_HOME/runInstaller -silent -responseFile response_file_name_with_full_path.
```
/u01/app/oracle/product/21.0.0/dbhome_1/runInstaller -silent -responseFile 
/u01/app/oracle/product/21.0.0/dbhome_1/install/response/db_install.rsp
```
使用 Oracle Database Configuration Assistant (DBCA) 以无提示模式或 GUI 模式创建 Oracle RAC 数据库。无提示模式示例：RDBMS_HOME/bin/dbca -silent -createDatabase -responseFile response_file_name_with_full_path.
```
[oracle@racvm1 ~]$ /u01/app/oracle/product/21.0.0/dbhome_1/bin/dbca -silent -
createDatabase -responseFile 
/u01/app/oracle/product/21.0.0/dbhome_1/assistants/dbca/dbca.rsp
```

验证 Oracle RAC 是否已成功创建。

[oracle@racvm1 ~]$ /u01/app/oracle/product/21.0.0/dbhome_1/bin/srvctl status db -d 
PCARACDB
Instance PCARACDB1 is running on node racvm1
Instance PCARACDB2 is running on node racvm2
