2、是要装,一般都是把安装脚本写好,跟你的应用程序一起打包装的。
3、ACCESS对生成的安装包比SQL要简单,至于要安全,数据部分可以用MD5算法加密,再写进数据库里。
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 USERCIDR-ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all alltrust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128trust
#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:
5.点击“确定”进行连接。
