解决方案：需要在三个节点上都部署好相关依赖包，单个节点依赖包不全可能会导致预安装不通过
yum install -y java-1.8.0-openjdk* psmisc* bzip2*
yum install -y python3-devel* python3* lksctp*

yum install -y  yum install -y libaio-devel* flex* bison* ncurses-devel* glibc-devel* patch* readline-devel* redhat-lsb-core* expect* ntp*

[GAUSS-52200] : Unable to import module: libpython3.6m.so.1.0: cannot open shared object file: No such file or directory.

再次执行预执行时会因前一次预执行已创建了一些目录和文件，会导致失败。可参照xml文件，将除/opt/software/openGauss之外的其它目录和文件

重新编译python,或者在其它已编译该python版本环境将libpython3.6m.so.1.0拷贝到当前服务器/usr/lib64 目录下
并在/etc/profile里执行 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/python3/bin，并source /etc/profile生效

[GAUSS-51806] : "The cluster has been installed."

reslove:

检查omm用户下的.bashrc文件中$GAUSS_ENV环境变量的值是否为2，如果是2就注释掉
GAUSS_ENV = 1 indicates successful pre-installation  表示预安装成功
GAUSS_ENV = 2 indicates successful installation 表示数据库已经安装成功

 

5.如果因为python环境变量原因无法执行gs_preinstall，可以这样执行：python3 /opt/software/openGauss/script/gs_preinstall -U omm -G dbgrp -X /opt/software/openGauss/clusterconfig.xml
