运行预检查

$ cd /u01/app/grid/product/12.2.0/grid_1/
$ ./runcluvfy.sh stage -pre crsinst -n nodea,nodeb -verbose

Verifying Single Client Access Name (SCAN) ...FAILED
  Verifying DNS/NIS name service 'node-scan' ...FAILED
  PRVG-1101 : SCAN name "node-scan" failed to resolve

SCAN 如果使用hosts方式的话，可以忽略

修正后，运行 gridSetup.sh

Configure Oracle Grid Infrastructure for a New Cluster

Configure an Oracle Standalone Cluster

Cluster Name : node-cluster
SCAN Name : node-scan
SCAN Port : 1521

role:HUB LEAF

GIMR data
at least 39,152MB

DNS/NIS

最后以root运行两个脚本

/u01/app/gridbase/12.2.0/oraInventory/orainstRoot.sh
/u01/app/grid/product/12.2.0/grid_1/root.sh

运行后再次检查

$ cd /u01/app/grid/product/12.2.0/grid_1/
$ ./runcluvfy.sh stage -post crsinst -n nodea,nodeb -verbose

step 3：安装 db

下载 linuxx64_12201_database.zip 解压后安装

Install database software only

Oracle Real Application Cluster database installation

最后以root运行脚本

/u01/app/oracle/product/12.2.0/db_1/root.sh

接下来用 dbca 创建数据库

Global database name : rac0
SID Prefix: rac0

em port：5500

URL=https://node-scan:5500/em

多节点安装前后都检测一下

./runcluvfy.sh stage -pre crsinst -n nodea,nodeb -verbose
./runcluvfy.sh stage -pre dbinst -n nodea,nodeb -verbose

./runcluvfy.sh stage -post crsinst -n nodea,nodeb -verbose
./runcluvfy.sh stage -post dbinst -n nodea,nodeb -verbose

./cluvfy stage -pre dbinst -n nodea,nodeb -verbose
./cluvfy stage -post dbinst -n nodea,nodeb -verbose
