客户这儿redhat 5.8下安装11gR2在安装grid时报错：INS-32026]The Software Location specified should not be under Oracle base location.
CAUSE: Grid Infrastructure for a Cluster installation will assign root ownership to all parent directories of clusterware software location. As a result, all named directories in the software location path will acquire root ownership. This may create problems for subsequent installations into the same Oracle base.
ACTION: Specify software location outside of Oracle base.

我设定的grid目录结构:
ORACLE_BASE=/app/grid
ORACLE_HOME=/app/grid/11.2.0/grid
其实就是ORACLE_HOME不能在ORACLE_BASE下，因为ORACLE_BASE下的目录和文件最后都改成了root属主了。
明白了原因后来修改为下面目录结果就可以了：
ORACLE_BASE=/app/grid/grid
ORACLE_HOME=/app/grid/11.2.0/grid
