安装 opengauss 1.01 for centos,执行完gs_preinstall后，/opt的权限变这样了
[root@cn1 opt]# ll total 28 drwxr-xr-x 6 root root 56 Jul 19 21:47 adbsql drwxr-xr-x 6 omm dbgrp 4096 Jul 10 2018 apache-ant-1.10.5 drwxr-xr-x 5 omm dbgrp 48 Jul 19 09:34 gaussdb -rw------- 1 omm dbgrp 1398 Jul 19 09:32 gdb.xml drwxr-xr-x 10 omm dbgrp 4096 Sep 4 2019 go drwxr-xr-x 5 omm dbgrp 48 Oct 21 22:08 huawei drwxr-xr-x 7 omm dbgrp 4096 Apr 2 2019 jdk1.8.0_211 drwxr-xr-x 13 mysql mysql 4096 Jul 26 11:32 mysql drwxrwxr-x 5 omm dbgrp 39 Feb 10 2019 netdata drwxr-xr-x 11 omm dbgrp 151 Apr 21 2019 nginx drwxr-xr-x. 2 omm dbgrp 6 Aug 25 2018 rh drwxr-xr-x 4 omm dbgrp 4096 Jul 19 09:32 soft drwxr-xr-x 11 omm dbgrp 151 Apr 21 2019 tengine drwxr-xr-x 9 omm dbgrp 4096 Dec 22 2019 tomcat 多改了几个文件夹的权限，看来opengauss要单独放在一个文件下比较好
