静默安装
本安装示例中，使用response文件进行静默安装，省去了Linux桌面机器的配置，如需通过GUI界面的方式安装，请于Oracle官方手册获取帮助。
Oracle Grid的默认静默安装配置文件位于/u01/app/grid_home/install/response/gridsetup.rsp，需要
Oracle DBA修改其中的配置项，一些关键的配置项如：
l oracle.install.crs.config.clusterNodes=rac-node01:rac-node01-vip,rac-node02:rac-node02-vip：设定集群节点。
l oracle.install.crs.config.networkInterfaceList=ens2:192.168.100.0:5,ens5:192.168.0.0:1：设定PUBLIC 和ASM&PRIVATE网络使用的网卡。
l oracle.install.asm.diskGroup.disks=/dev/vdc,/dev/vdd,/dev/vde：设定仲裁盘。
静默安装的配置文件准备好之后，可先进行依次尝试安装（切换到grid用户，并切换到/u01/app/grid_home/目录）：
[grid@rac-node01 grid_home]$ ./gridSetup.sh -silent -responseFile
install/response/gridsetup.rsp
尝试安装如果失败，需要提示的报错日志，依次排查报错项，处理完错误问题或确认遗留问题可忽略，则可以通过添加-ignorePrereqFailure参数跳过依赖报错问题。
[grid@rac-node01 grid_home]$ ./gridSetup.sh -silent -ignorePrereqFailure -
responseFile install/response/gridsetup.rsp
安装后执行脚本
安装完成之后，执行输出会提示需要以root账号执行脚本，分别在各个节点上执行：
[root@rac-node01 ~]# /u01/app/oraInventory/orainstRoot.sh
[root@rac-node01 ~]# /u01/app/grid_home/root.sh
安装后检查
注意：由于心跳线haip功能暂时无法使用，心跳通信受阻，OCR disk group会显示未正常挂载。没有心跳线负载均衡需求的用户，可以通过禁用haip功能，将集群状态恢复。
[root@rac-node01 ~]# crsctl stat res -t

查看public和private网卡使用情况：
[root@rac-node01 ~]# oifcfg iflist
ens2 192.168.100.0
ens5 192.168.0.0
[root@rac-node01 ~]# oifcfg getif

ens5 192.168.0.0 global public
Grid安装后配置（重要）
对于没有多条心跳线需要做心跳线高可用、负载均衡的用户，可以通过以下步骤将 interconnect HAIP 功能禁用。禁用此功能，不影响Oracle RAC正常功能使用。
l 所有node上停止crs
crsctl stop crs
l 依次在各个节点上，执行以下禁用haip作为依赖的命令
crsctl start crs -excl -nocrs
crsctl stop res ora.asm -init
crsctl modify res ora.cluster_interconnect.haip -attr "ENABLED=0" -init
crsctl modify res ora.asm -attr
"START_DEPENDENCIES='hard(ora.cssd,ora.ctssd)pullup(ora.cssd,ora.ctssd)weak(ora.drivers.acfs)',STOP_DEPENDENCIES='hard(intermediate:ora.cssd)'" -init
crsctl stop crs
l 顺序启动各个节点
crsctl start crs
l 检查集群状态，OCR diskgroup 已ONLINE
[root@rac-node01 ~]# crsctl stat res -t
