安装GRID软件

1、解压缩Grid软件

chown -R grid:oinstall /soft
su - grid -c "unzip /soft/linuxx64_12201_grid_home.zip -d /u01/app/12.2.0/grid"

2、RPM CVU 安装

rpm -ivh /soft/compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm
rpm -ivh /soft/cvuqdisk-1.0.10-1.rpm

3、配置ssh互信

#SSH配置 (自root用户下执行)
/u01/app/12.2.0/grid/oui/prov/resources/scripts/sshUserSetup.sh -user oracle -hosts "fdcdb01 fdcdb02 fdcdb01-priv1 fdcdb01-priv2 fdcdb02-priv1 fdcdb02-priv2" -advanced -noPromptPassphrase -exverify -confirm
/u01/app/12.2.0/grid/oui/prov/resources/scripts/sshUserSetup.sh -user grid -hosts "fdcdb01 fdcdb02 fdcdb01-priv1 fdcdb01-priv2 fdcdb02-priv1 fdcdb02-priv2" -advanced -noPromptPassphrase -exverify -confirm

4、安装前runcluvfy检查

su - grid -c "/u01/app/12.2.0/grid/runcluvfy.sh stage -pre crsinst -n fdcdb01,fdcdb02 -fixup -verbose"


Pre-check for cluster services setup was unsuccessful on all the nodes. 


Failures were encountered during execution of CVU verification request "stage -pre crsinst".

5、安装GRID软件

Notes：提前剧透下，一定要看：如果安装命令是执行./gridSetup.sh，执行root.sh时，__必然报错：CLSRSC-400: A system reboot is required to continue installing.需要卸载重新安装。

解决方案：通过12C新特性 -applyPSU 提前打上最新PSU补丁修复该BUG，前提是需要更换OPatch包：

**How to Apply a Grid Infrastructure Patch Before Grid Infrastructure Configuration (before root.sh or rootupgrade.sh or gridsetup.bat) is Executed (Doc ID 1410202.1)    **

./gridSetup.sh -applyPSU /soft/32226491

以下是完整的安装以及填坑步骤：
