PostgreSQL服务端监听设置及客户端连接方法

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

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：
