【功能模块】
根据“在ECS上部署openGauss数据库指导手册”文件在弹性云服务器（系统为openEuler）上安装openGauss数据库，在执行到“采用交互模式执行创建openGauss omm用户互信”一步中出现错误。
【操作步骤&问题现象】
1、前置操作完成后执行# python gs_preinstall -U omm -G dbgrp -X /opt/software/openGauss/clusterconfig.xml这一命令
2、服务器中出现错误信息：找不到_psutil_linux.so这个文件

建议方向：
1、检查文件是否真的不存在，或者是文件权限是否正确；
2、在网上或其他机器拷贝该文件到自己机器上，重新[/quote]
3、请检查下python版本 可以用python3试下
