背景介绍:
PostgreSQL服务端运行在RedHat Linux上,IP为:192.168.230.128
客户端安装在Windows XP上, IP为:192.168.230.1
配置方法:
1. 修改服务端/opt/postgresql/data/postgresql.conf文件,将
#listen_address='localhost'改成 listen_address='*'2. 修改/opt/postgresql/data/gp_hba.conf文件
在其中增加客户端的ip,如下,注意最后一行:
# 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 trust3.重启PG服务
[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. 使用客户端连接,配置如下:

5.点击“确定”进行连接,成功后,如下:

本文详细介绍如何在RedHat Linux服务器端与Windows XP客户端之间配置PostgreSQL服务,实现跨平台数据库连接。主要内容包括:修改服务端配置文件以监听所有地址、增加特定客户端IP的信任连接、重启服务以及使用客户端进行验证连接。
