本文主要是将RAC OUI安装做一个图形化细节记录

基础信息

硬件规划:

网卡至少两张 public / private

CD/DVD ####用于依赖安装

磁盘 ： / 根盘  

asm-ocr  ##共享磁盘

asm-data ##共享磁盘

###物理机可不需要

/soft  50G使用时分配 用完可删除 ##共享 虚拟机上建议

/u01  60G使用时分配   ##虚拟机上建议

RAC信息规划:

主机名 racnode1  racnode2

IP地址

public:  192.168.11.156  192.168.11.157     

private: 192.168.201.156 192.168.201.157

vip:     192.168.11.158  192.168.11.159

scan:    192.168.11.160

实例名：racdb1 racdb2  

提前准备(略)

1、GI安装

su - grid

export CV_ASSUME_DISTID=RHEL7.6

export SSH_AUTH_SOCK=0

export

export DISPLAY=192.168.11.1:0.0

cd $ORACLE_HOME

./gridSetup.sh

step1: Specify the installation option

对应responsfile：  oracle.install.option=CRS_CONFIG

step2:

对应responsfile：
oracle.install.crs.config.ClusterConfiguration=STANDALONE
oracle.install.crs.config.configureAsExtendedCluster=false

step3:

scan name与主机配置的一致,也可使用oui默认带出来的名称,一致即可。

对应responsfile：
oracle.install.crs.config.clusterName=racnode-cluster
oracle.install.crs.config.gpnp.scanName=racnode-scan
oracle.install.crs.config.gpnp.scanPort=1521

step4:

如信任有问题可考虑如下信任创建和验证:

##删除已有的ssh配置

rm -f /home/grid/.ssh/*

rm -f /home/oracle/.ssh/*

##--手动互信

su - grid

cd $ORACLE_HOME

export SSH_AUTH_SOCK=0

./oui/prov/resources/scripts/sshUserSetup.sh -user grid  -hosts "racnode1 racnode2" -advanced -confirm -noPromptPassphrase

./oui/prov/resources/scripts/sshUserSetup.sh -user oracle  -hosts "racnode1 racnode2" -advanced -confirm -noPromptPassphrase

ssh racnode2 date

##对等验证

su - grid

$ORACLE_HOME/runcluvfy.sh comp admprv -n racnode1,racnode2 -o user_equiv -sshonly -verbose

##完毕，执行互相验证

su - oracle

date;ssh racnode1 date;ssh racnode1 date;ssh racnode2 date;ssh racnode2 date;ssh racnode1 date

su - grid

date;ssh racnode1 date;ssh racnode1 date;ssh racnode2 date;ssh racnode2 date;ssh racnode1 date

对应responsfile：
oracle.install.crs.config.clusterNodes=racnode1:racnode1-vip,racnode2:racnode2-vip

step5:

对应responsfile:
oracle.install.crs.config.networkInterfaceList=ens160:192.168.11.0:1,ens224:192.168.201.0:5,virbr0:192.168.122.0:3

step6:

oracle.install.crs.config.storageOption=FLEX_ASM_STORAGE

step7:

oracle.install.crs.configureGIMR=false

step8:

oracle.install.asm.diskGroup.name=OCR
oracle.install.asm.diskGroup.redundancy=EXTERNAL
oracle.install.asm.diskGroup.AUSize=4
oracle.install.asm.diskGroup.disks=/dev/asm_ocr
oracle.install.asm.diskGroup.disksWithFailureGroupNames=/dev/asm_ocr,
oracle.install.asm.diskGroup.diskDiscoveryString=/dev/as*

step9:

oracle.install.asm.SYSASMPassword=

oracle.install.asm.monitorPassword=

step10:

oracle.install.crs.config.useIPMI=false
oracle.install.crs.config.ipmi.bmcUsername=
oracle.install.crs.config.ipmi.bmcPassword=

step11:

oracle.install.config.managementOption=NONE
oracle.install.config.omsHost=
oracle.install.config.omsPort=0
oracle.install.config.emAdminUser=
oracle.install.config.emAdminPassword=

step12:

oracle.install.asm.OSDBA=asmdba
oracle.install.asm.OSOPER=asmoper
oracle.install.asm.OSASM=asmadmin

step13:

ORACLE_BASE=/u01/app/grid

step14:

INVENTORY_LOCATION=/u01/app/oraInventory

step15:

oracle.install.crs.rootconfig.executeRootScript=false
oracle.install.crs.rootconfig.configMethod=
oracle.install.crs.rootconfig.sudoPath=
oracle.install.crs.rootconfig.sudoUserName=
step16:

resolv.conf 、scan 、dns/nis 均与域名服务器有关, 使用本地域名 忽略
ntp未配置, 如解决此错误需配置时间服务器,这里已有公共时间同步服务器,ntpdate -u 同步即可，忽略
physical Memory /swap  这里是虚拟机资源有限忽略。物理机环境针对解决处理warning。

step17:

step18:

两个脚本在两个节点分别执行(主节点先执行完成 后续节点在依次执行)，全部节点均执行完成后 OK继续

执行日志:

[root@racnode1:/root]$ /u01/app/oraInventory/orainstRoot.sh

Changing permissions of /u01/app/oraInventory.

Adding read,write permissions for group.

Removing read,write,execute permissions for world.

Changing groupname of /u01/app/oraInventory to oinstall.

The execution of the script is complete.

[root@racnode1:/root]$ /u01/app/19.3.0/grid/root.sh

Performing root user operation.

The following environment variables are set as:

    ORACLE_OWNER= grid

    ORACLE_HOME=  /u01/app/19.3.0/grid

Enter the full pathname of the local bin directory: [/usr/local/bin]:

   Copying dbhome to /usr/local/bin ...

   Copying oraenv to /usr/local/bin ...

   Copying coraenv to /usr/local/bin ...

Creating /etc/oratab file...

Entries will be added to the /etc/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root script.

Now product-specific root actions will be performed.

Relinking oracle with rac_on option

Using configuration parameter file: /u01/app/19.3.0/grid/crs/install/crsconfig_params

step19:

grid安装完毕

2、创建磁盘组

asmca 

##检查 asm 磁盘：

asmcmd lsdg

然后检查集群状态：

crsctl stat res -t

3、数据库软件安装

su - oracle

##进入ORACLE_HOME目录

cd $ORACLE_HOME

##执行安装程序开始安装

export CV_ASSUME_DISTID=RHEL7.6

export SSH_AUTH_SOCK=0

export

export DISPLAY=192.168.11.1:0.0
