PostgreSQL数据库服务端监听设置及客户端连接方法教程

众所周知,PostgreSQL 是一个自由的对象-关系数据库服务器(数据库管理系统),是一个可以免费使用的开放源代码数据库系统。本文详细介绍了PostgreSQL数据库服务端监听设置及客户端连接方法,具体如下:

一、背景介绍:

本文所述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

二、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     trust

3.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:
