眾所周知,PostgreSQL 是一個(gè)自由的對象-關(guān)系數(shù)據(jù)庫服務(wù)器(數(shù)據(jù)庫管理系統(tǒng)),是一個(gè)可以免費(fèi)使用的開放源代碼數(shù)據(jù)庫系統(tǒng)。本文詳細(xì)介紹了PostgreSQL數(shù)據(jù)庫服務(wù)端監(jiān)聽設(shè)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(wù)端運(yùn)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(wù)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,注意最后一行:
# TYPE DATABASE USER CIDR-ADDRESS METHOD# "local" is for Unix domain socket connections onlylocal 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(wù):
[postgres@localhost data]$ pg_ctl restartwaiting for server to shut down....LOG: received smart shutdown requestLOG: autovacuum launcher shutting downLOG: shutting downLOG: database system is shut down doneserver stoppedserver starting[postgres@localhost data]$ LOG: database system was shut down at 2011-07-09 14:54:29 CSTLOG: autovacuum launcher startedLOG: database system is ready to accept connections[postgres@localhost data]$
4. 使用客戶端連接,配置如下:
5.點(diǎn)擊“確定”進(jìn)行連接,成功后,如下:
