第二部分 iODBC
一.iODBC简介
iODBC是个免费的MySQL库ODBC接口.因为短小精悍,广为流传.
二.iODBC安装
1.从 ftp://166.111.68.178/linux/database下载
iodbc-2.12-3.src.rpm
!!!(不要下载iodbc-2.12-3.i386.rpm ,该包有问题,自带的ODBC
工具monitor,odbctool可以执行,但是链接iodbc.so自己写
的程序链接出错,如果只是用它的工具当然可以,二次开发
就不行了.)
2.用 rpm -ivh iodbc-2.12-3.src.rpm 解开 ,生成文件
/usr/src/redhat/SOURCES/iodbc-2.50.11.tgz ,找个目录
解开 tar zxvf /usr/src/redhat/SOURCES/iodbc-2.50.11.tgz
建议放在 /usr/local 下,会建立目录 iodbc.
3.要想iODBC-src正常编译,需要修改很多文件,包括
iodbc/SAMPLES/Makefile
iodbc/myodbc-2.50.11/config.h
iodbc/myodbc-2.50.11/m_string.h
iodbc/myodbc-2.50.11/connect.c
为方便使用,我将改动过的iODBC打了一个包,叫做
iodbc-2.50.11-lg.tgz, :-)权充一回自由软件者.因为上网不便,
暂时还没有放上来,抱歉. //sorry
4.安装后iODBC在/usr/lib/iodbc 之下.配置文件为iodbc.ini .
三.iODBC配制
其实 iodbc.ini 文件已经讲地很详细了,我这里再多说什么也很多余,
那我就讲些它没说的.
iodbc.ini中有一项是设置 SERVER 的,就是 MySQL 数据库所在的
机器名,在iodbc-2.12-3.src.rpm和iodbc-2.12-3.i386.rpm中都是
摆设:p,网上我看到的好象都是酱紫的.后来我改动了一些iODBC中
的一些ODBC驱动程序,(//smile,真是要为开放源代码欢呼了!!!).
~~~~~~~~~~~~~~~~~~
让它访问远端的MySQL服务器.细节暂时保密,其实你可以看代码的说.
现在好了,就是在iodbc.ini文件里设置[identify] 和 DSN 必须是
相同的,DB才是远端实际的数据库名.至于本地机就不用设DB了,
推荐的远端DSN命名方法为 databasename.hostname ,即:
本地: [identify] //随意.hehe
DSN = databasename
SERVER = localhost
...
远端: [databasename.hostname]
DSN = databasename.hostname
SERVER = hostname
...
很简单吧. :-)
