【ORA】[INS-30131]Failed to access the temporary location

[INS-30131] Initial setup required for the execution of installer validations failed.

场景：
在linux下安装rac，因节点和节点二oracle和grid用户组的组号不一样，在节点一手动修改了组号，安装GI时报错
SEVERE: [FATAL] [INS-30131] Initial setup required for the execution of installer validations failed.   
CAUSE: Failed to access the temporary location.    
ACTION: Ensure that the current user has required permissions to access the temporary location.
解决：
提示是/tmp这个目录，登录到/tmp/CVU_11.2.0.4.0_grid查看
# ll /tmp/CVU_11.2.0.4.0_grid
drwxr-xr-x. 2 54322 54321 4096 Feb 13 09:11 scratch
发现用户和组变成了这样的数字54322 54321，正常应该是grid:oinstall

修改/tmp目录下变成数字的文件以及/home/oracle和/home/grid错乱的用户和用户组

一般是文件的权限问题
