解決方案：需要在三個節點上都部署好相關依賴包，單個節點依賴包不全可能會導致預安裝不通過
yum install -y java-1.8.0-openjdk* psmisc* bzip2* yum install -y python3-devel* python3* lksctp*

再次執行預執行時會因前一次預執行已創建了一些目錄和文件，會導致失敗。可參照xml文件，將除/opt/software/openGauss之外的其它目錄和文件

重新編譯python,或者在其它已編譯該python版本環境將libpython3.6m.so.1.0拷貝到當前服務器/usr/lib64 目錄下 並在/etc/profile裏執行 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/python3/bin，並source /etc/profile生效

檢查omm用戶下的.bashrc文件中$GAUSS_ENV環境變量的值是否爲2，如果是2就註釋掉
GAUSS_ENV = 1 indicates successful pre-installation 表示預安裝成功
GAUSS_ENV = 2 indicates successful installation 表示數據庫已經安裝成功
5.如果因爲python環境變量原因無法執行gs_preinstall，可以這樣執行：python3 /opt/software/openGauss/script/gs_preinstall -U omm -G dbgrp -X /opt/software/openGauss/clusterconfig.xml
