上传oracle软件

本次安装的是网上下载的学习版本

点击链接SFTP标签页，按下图步骤上传安装文件；

 

在 rac1 上解压安装包，解压到/tmp 目录下， 解压出 database 目录和 grid 目录；

# unzip -d /tmp/ p13390677_112040_Linux-x86-64_1of7.zip
# unzip -d /tmp/ p13390677_112040_Linux-x86-64_2of7.zip
# unzip -d /tmp/ p13390677_112040_Linux-x86-64_3of7.zip

在 rac2 上，提取一个cvuqdisk-1.0.9-1.rpm包，是一个验证工具；

[root@rac2 ~]# mkdir -p /tmp/grid/rpm
[root@rac2 ~]# scp root@192.168.5.111:/tmp/grid/rpm/cvuqdisk-1.0.9-1.rpm /tmp/grid/rpm/

安装集群验证工具（cvu）

//检查有没有安装cvuqdisk包
[root@rac1 tmp]# rpm -qa cvuqdisk
//切换环境
[root@rac1 tmp]#export CVUQDISK_GRP=oinstall
[root@rac1 tmp]#cd /tmp/grid/rpm
[root@rac1 tmp]#rpm -ivh cvuqdisk-1.0.9-1.rpm
Preparing...                ########################################### [100%]
   1:cvuqdisk               ########################################### [100%]

//rac2上也要操作
[root@rac2 ~]# export CVUQDISK_GRP=oinstall
[root@rac2 ~]# cd /tmp/grid/rpm
[root@rac2 rpm]# rpm -ivh cvuqdisk-1.0.9-1.rpm

配置ssh互信

我们使用sshUserSetup.sh的脚本，该脚本在我们刚才上传后解压的目录下（/tmp/grid/sshsetup），在rac1上以root用户执行以下命令；

[root@rac1 sshsetup]# /tmp/grid/sshsetup/sshUserSetup.sh -user grid -hosts "rac1 rac2" -advanced exverify -confirm
。。。输入yes及grid密码，然后一路回车就可以了
[root@rac1 sshsetup]# /tmp/grid/sshsetup/sshUserSetup.sh -user oracle -hosts "rac1 rac2" -advanced exverify -confirm
。。。输入yes及oracle密码，然后一路回车就可以了

测试一下，第二次不用输入密码，则表示SSH对等性配置成功。

安装前检查

切换到grid用户，在/tmp/grid目录下，执行脚本；

你会看到一堆pass，除了下面这3个：

第1个是缺少pdksh包，我们在网上下载安装，也可以忽略；

第2个是NTP，我们已经取消，不用理会；

第3个是没有配置DNS（只在hosts文件里标明），检测/etc/resolv.conf会失败的，可以忽略该警告，直接 ignore 即可,不影响安装。

./runcluvfy.sh stage -pre crsinst -n rac1
