小编给大家分享一下Oracle 安装前 runcluvfy.sh脚本怎么用，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
Oracle 官方建议在安装Oracle Grid Infrastructure前运行此脚本，来检查各个节点是否满足GI安装的官方要求.
在部署Grid Infrastructure的过程中使用，我们不光要学会怎么用这个脚本，更应该明白其中的一些原理。
runcluvfy.sh将功能在shell中实现，并和GI的安装介质一起提供给用户，使得用户在数据库和CLUSTER安装之前就可以利用这个工具的功能。
先看一下脚本的基本用法
./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose
./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose
语法说明：
-pre： 该选项主要检查是否满足安装的需要。
-post：该选择主要检查安装后组件是否正常。
-n：该选项用于指定节点列表，这里指定了2个节点。
-verbose：该选项用于输出详细的验证信息。
-fixup：这是Oracle 11gR2中新增加的一个参数。利用这个参数，可以产生一个名为runfixup.sh的脚本。
runfixup.sh脚本中包含一系列的操作系统命令，利用这个脚本可以对操作系统进行一定的修改，使其满足安装条件。
完成系统进行校验之后，以root用户的身份执行脚本runfixup.sh，就可以解决操作系统中一些尚不满足安装条件的情况。
附一个我的测试库的输出结果
crmdb1:/oracle@grid> ./runcluvfy.sh stage -pre crsinst -n crmdb1,crmdb2 -verbose
