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          trust

3.重启PG服务

[postgres@localhost data]$ pg_ctl restart
