经分析排查，原因是在安装Python3的时候，没有指定目录，导致它的一些依赖库和系统自带的Python2库文件冲突导致的。使用下面的方法在各个节点重新安装Python3即可：

[root@hwd01 ~]# mkdir /usr/local/python373
[root@hwd01 ~]# tar -xzf /mnt/Python-3.7.3.tgz 
[root@hwd01 ~]# cd Python-3.7.3/
[root@hwd01 ~]# ./configure --prefix=/usr/local/python373&& make && make install
编辑/etc/profile，加入以下内容：
[root@hwd01 ~]# vi /etc/profile
export PATH=${PATH}:/usr/local/python373/bin
[root@hwd01 ~]# source /etc/profile
[root@hwd01 ~]# python3 -V
Python 3.7.3

再次执行gs_install脚本，如下:

[omm@hwd01 ~]$ gs_install -X /tmp/clusterconfig3C3D.xml
