眾所周知,PostgreSQL 是一個自由的對象-關系數據庫服務器(數據庫管理系統),是一個可以免費使用的開放源代碼數據庫系統。本文詳細介紹了PostgreSQL數據庫服務端監聽設置及客戶端連接方法,具體如下:
一、背景介紹:
本文所述PostgreSQL服務端運行在RedHat Linux上,IP為:192.168.230.128
客戶端安裝在Windows XP上, IP為:192.168.230.1
二、配置方法:
1.修改服務端/etc/postgresql/9.5/main/postgresql.conf文件,將:
1
|
#listen_address=
'localhost'
|
改成
1
|
listen_address=
'*'
|
2.修改/etc/postgresql/9.5/main/gp_hba.conf文件:
在其中增加客戶端的ip,如下,注意最后一行:
