這個問題很好處理，它是ssh自己，看下ssh服務(wù)，第一次啟動的時候應(yīng)該是啟動腳本里附帶了啟動sshd服務(wù)，之后再啟動，需要自己手動啟動下sshd服務(wù)，此處是centos6.8的系統(tǒng)

客戶端連接

連接之前需要修改pgdb的配置文件，允許客戶端所在網(wǎng)絡(luò)可以連接 配置文件目錄可以在初始化pgdb的時候看到

bash-4.1$ cd /workspace/gpdb/gpAux/gpdemo/datadirs/qddir/demoDataDir-1 
bash-4.1$ vi pg_hba.conf 
添加 host all all 192.16.126.0/24 trust 
重啟gpdb 
bash-4.1$ gpstop -r

下載windows客戶端

https://www.postgresql.org/ftp/pgadmin/pgadmin3/v1.22.2/win32/

安裝之后啟動連接

成功連接
