安装Freetds Freetds 是应用最为广泛的 Linux 下的 ODBC 驱动，官网：http://www.freetds.org/。因为我们用的版本是 0.82 版，而 Ubuntu 的更新源里仍然是 0.63 版本，我这边建议你执行 sudo apt-get remove freetds freetds-dev 来把以前装的版本删除掉，然后下载 0.82 或更新的版本。
编译 freetds 的时候一定要注意 configure 的参数，我估计当时我编译的时候参数没有设置正确，所以一直没有能够连上 mssql server。Vcc 分享了他的编译参数，如下：
./configure \
--prefix=/etc/freetds \
--with-tdsver=8.0 --enable-msdblib \
--enable-dbmfix \
--with-gnu-ld \
--enable-shared \
--enable-static
执行 configure 之后再 sudo make，sudo make install，耐心等候安装完成就可以了。
安装完成后，该用 tsql 测试一下，测试的方式是执行：
tsql –H mssql-server-ip –U username –P password
出现 1> 提示符就是成功啦。
配置 freetds
Freetds 的配置文件位置在 /etc/freetds/freetds.conf 里，打开后在最后面增加如下一个 section：
138 [db4]
139     host = 192.168.18.4
140     port = 1433
141     tds version = 7.0
其中 host 是 mssql server 的地址，tds version 是指定使用哪个 tds 版本，据 vcc 说，用 7.0 的兼容性比较好，我小试了一下，8.0 也是可以的。
完成以后，应该用 tsql 测试一下，测试的方式是执行：
tsql –S db4 –U username –P password
看到 1> 标识符就是成功啦。
