第6步：检查grid安装环境

6.1 检查系统包

grid 身份下校验安装环境（检测crs安装环境(sgdb1)）

[root@node1 soft]#su – grid

[grid@node1 ~]$ cd /soft/grid

[grid@node1 grid]$ ./runcluvfy.sh stage -pre crsinst -n sgdb1,sgdb2 -fixup -verbose

//pre-安装前，post-安装后，阶段名称叫crsinst-crsinstall，-n-节点之间校验，verbose-校验的过程

执行结果如下：

[grid@sgdb1 grid]$ ./runcluvfy.sh stage -pre crsinst -n sgdb1,sgdb2 -fixup -verbose

6.2逐条解决问题，再次校验

根据提示，逐条解决问题，然后再次执行下列语句进行校验。

[grid@node1 grid]$ ./runcluvfy.sh stage -pre crsinst -n sgdb1,sgdb2 -fixup -verbose

附：使用DVD光盘作为yum源

引入光盘后，手工挂在光盘

[root@node1 yum.repos.d]#mount /dev/cdrom /media //vbox设置完毕后，手工挂载光盘

[root@node1 yum.repos.d]# ls /media/ //可以查看一下目录下文件

、新建/etc/yum.repos.d/dvd.repo，添加如下内容并保存

[base]
name=Server

baseurl=file:///media/Server

enable=1
gpcheck=1

gpgkey=file:///media/RPM-GPG-KEY-RedHat-release

注：若文件路径中有空格，需要将其转义成%20

、清空yum缓存配置，使新路径生效

[root@localhost ~]# yum clean all

Loaded plugins: fastestmirror

Cleaning up Everything

Cleaning up list of fastest mirrors

//安装rpm包

[root@localhost ~]# yum install gcc* -y
