Linux 配置 unixODBC 访问 MS SQL Server 说明

一.安装 unixODBC

这个使用YUM安装一下,不多说:

[root@rac1 mnt]# yum install unixODBC     

[root@rac1 mnt]# yum install unixODBC-devel

 

确认unixODBC的安装,使用 isql命令,其是unixODBC自带的命令。可以使用这个命令验证unixODBC的配置。

 

[root@rac1 /]# isql --version

unixODBC 2.2.14

[root@rac1 /]# which isql

/usr/bin/isql

[root@rac1 /]# isql

二.安装 FreeTDS

freeTDS官网地址:http://www.freetds.org/

FreeTDS is a setof libraries for Unix and Linux that allows your programs to natively talk toMicrosoft SQL Server and Sybase databases.

--FreeTDS是Unix 和Linux library的一个集合,通过FreeTDS可以连接到MicrosoftSQL Server 和 Sybase DB。

 

2.1 下载freeTDS:

[root@rac1 ~]# wget http://ibiblio.org/pub/Linux/ALPHA/freetds/current/freetds-current.tgz

--2012-03-06 10:14:43-- http://ibiblio.org/pub/Linux/ALPHA/freetds/current/freetds-current.tgz

2.2 安装freeTDS:

FreeTDS 的安装帮助,可以参考:

unixODBC - MS SQL Server/PHP

http://www.unixodbc.org/doc/FreeTDS.html 

[root@rac1 ~]# tar xzf freetds-current.tgz

 

--查看configure的帮助文档:

[root@rac1 freetds-0.92.dev.20120305]# ./configure --help

 

--官网提供的方法:
# ./configure --with-tdsver=8.0--with-unixodbc=/usr/local 
# make 
# make install

 

注意这里:

如果 unixODBC是源码安装, 则–with-unixodbc=/usr/local
如果 unixODBC是rpm安装, 则不需要该选项

 

我们的unixODBC 是通过RPM包安装的,所以这里我们省略这个选项,直接configure。

 

# ./configure --with-tdsver=8.0 --prefix=/usr/local/freetds --enable-msdblib  --with-gnu-ld  --enable-shared  --enable-static

--这次configure成功。这里我们将freetds 安装到/usr/local 目录下。

 

然后make:

# make 
# make install

 

2.3 配置环境变量

将freetds的库文件所在路径配置到LD_LIBRARY_PATH参数中: 
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/freetds/lib/: 

设置bin路径 
$vi /root/.bashrc 
添加内容如下: 
export FREETDS=/usr/local/freetds 
export $PATH="$PATH:$FREETDS/bin" 

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/freetds/lib
