問題描述：使用redhat7.9來安裝opengauss集羣，預安裝過不去。opengauss官方只支持centos版本，最好是centos7.6。
[root@db01 script]# ./gs_preinstall -U omm -G dbgrp -X /opt/software/openGauss/clusterconfig.xml Parsing the configuration file. Successfully parsed the configuration file. Installing the tools on the local node. [GAUSS-50201] : The /opt/software/openGauss/openGauss-3.0.3-RedHat-64bit.tar.bz2 does not exist.
官方解決文檔:https://gitee.com/opengauss/openGauss-OM/issues/I3HXVL 解決文檔給了幾種方式，但是我的並沒有通過
方式一:修改/etc/redhat-release版本信息
# cat /etc/redhat-release #Red Hat Enterprise Linux Server release 7.9 (Maipo) CentOS Linux release 7.6.2003 (Core)
方式二: 修改/etc/os-release 的redhat的信息爲centos相關的
# cat /etc/os-release NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" CENTOS_MANTISBT_PROJECT="CentOS-7" CENTOS_MANTISBT_PROJECT_VERSION="7" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION="7"
方式三:修改script/gspylib/os/gsplatform.py文件，具體修改內容如下
將1500行左右的PAK_REDHAT修改爲PAK_CENTOS,修改後的截圖如下：
以上在我的opengauss3.0.0+redhat7.9版本沒通過,但是可以通過修改軟件包名稱通過預安裝

修改解壓文件名稱，此方式可以通過
