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/opt/postgresql/data/postgresql.conf文件,將:
#listen_address='localhost'
改成
listen_address='*'
2.修改/opt/postgresql/data/gp_hba.conf文件:
在其中增加客戶端的ip,如下,注意最後一行:
# TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust # IPv4 local connections: host all all 127.0.0.1/32 trust # IPv6 local connections: host all all ::1/128 trust #kevin add # IPv4 local connections: host all all 192.168.230.1/32 trust
3.重啟PG服務:
[postgres@localhost data]$ pg_ctl restart waiting for server to shut down....LOG: received smart shutdown request LOG: autovacuum launcher shutting down LOG: shutting down LOG: database system is shut down done server stopped server starting [postgres@localhost data]$ LOG: database system was shut down at 2011-07-09 14:54:29 CST LOG: autovacuum launcher started LOG: database system is ready to accept connections [postgres@localhost data]$
4. 使用客戶端連接,配置如下:
5.點擊“確定”進行連接,成功後,如下:
