1、数据库的关闭
[gpadmin@mdw ~]$ gpstop 20190506:16:16:39:053775 gpstop:mdw:gpadmin-[INFO]:-Starting gpstop with args: 20190506:16:16:39:053775 gpstop:mdw:gpadmin-[INFO]:-Gathering information and validating the environment... 20190506:16:16:39:053775 gpstop:mdw:gpadmin-[CRITICAL]:-gpstop failed. (Reason='[Errno 2] No such file or directory: '/home/gpadmin/gpadata/gpmaster/gpseg-1/postgresql.conf'') exiting...
原因：因该是找不到MASTER_DATA_DIRECTORY目录，
我们可以指定数据目录 -d ，避免这种问题
[gpadmin@mdw ~]$ gpstop -M fast -v -d /home/gpadmin/gpdata/gpmaster/gpseg-1 -l /home/gpadmin/gpAdminLogs
gpstop -M fast ： 以快速模式关闭Greenplum数据库系统
2、数据库的启动
