关于mac osx上安装 freetds unixodbc 及安装碰到的问题
from:http://tcspecial.iteye.com/blog/1972740
1.首先我们应该安装unixodbc
brew install unixodbc
2.然后我们安装freetds：
brew install freetds --with-unixodbc
3.然后我们需要先配置freetds中的数据源：
应该在 /usr/local/etc/freetds.conf
#A typical Microsoft server
[testdsn] # SQL Server数据源名称,可以任意取有意义的名称
host=192.168.10.22 # 数据库主机
port=1344 #数据库监听端口
tds version=8.0 #默认7.0
4.然后我们有了数据源，应该去odbc中配置odbcinst.ini和odbc.ini
odbcinst.ini的地址，我这里是：
AndyMacBookPro:lib andy$ sudo find / -name odbcinst.ini
Password:
find: /dev/fd/3: Not a directory
find: /dev/fd/4: Not a directory
/usr/local/Cellar/unixodbc/2.3.2/etc/odbcinst.ini
/usr/local/etc/odbcinst.ini
AndyMacBookPro:lib andy$ ll /usr/local/etc/odbcinst.ini
lrwxr-xr-x 1 andy admin 41 6 30 20:41 /usr/local/etc/odbcinst.ini@ -> ../Cellar/unixodbc/2.3.2/etc/odbcinst.ini
AndyMacBookPro:lib andy$
odbcinst.ini中的libtdsodbc.so的路径要自己确定，我这里是位于：
#Driver=/usr/local/freetds/lib/libtdsodbc.so #指定TDS驱动路径
Driver=/usr/local/Cellar/freetds/0.91/lib/libtdsodbc.so
odbcinst.ini：
[FREETDS]
Description=freetds driver
Driver=/usr/local/freetds/lib/libtdsodbc.so #指定TDS驱动路径
Trace=yes
TraceFile=/tmp/odbc.log # 启用ODBC日志记录
odbc.ini：
[testdsn] # 数据源名称
Driver=FREETDS # 指向odbcinst.ini的驱动配置
Description=MSSQL Server
Servername=testdsn # 数据源名称
Database=sqlscada #数据库名称
然后就配置结束了，我们可以是用freetds+unixodbc访问mssql了~~~
之前碰到了问题，freetds编译之后一直找不到libtdsodbc.so的问题，现在终于明白，
要先安装unixodbc，然后要在brew安装freetds的时候一定要加上：
brew install freetds--with-unixodbc
这样就可以了！
yes！
如果我们想要使用php来连接mssql数据库，可能会有问题：
因为我们的php的mssql扩展不存在，无法连接mssql数据库，该怎么办呢？
var_dump(function_exists(mssql_connect));

我们可以看到brew link 这次终于成功了，是因为我到了/usr/local/share/ 中删掉了整个freetds-0.91目录才成功的，不然会一直报错。
然后我们终于可以开始安装php54-pdo-dblib了~~
AndyMacBookPro:/ andy$ brew install php54-pdo-dblib

==> Caveats
To finish installing pdo_dblib for PHP 5.4:
* /usr/local/etc/php/5.4/conf.d/ext-pdo_dblib.ini was created,
do not forget to remove it upon extension removal.
* Validate installation via one of the following methods:
*
* Using PHP from a webserver:
* - Restart your webserver.
* - Write a PHP page that calls "phpinfo();"
* - Load it in a browser and look for the info on the pdo_dblib module.
* - If you see it, you have been successful!
*
* Using PHP from the command line:
* - Run "php -i" (command-line "phpinfo()")
* - Look for the info on the pdo_dblib module.
* - If you see it, you have been successful!

但是我们发现我们要装的是不是pdo-dblib这个东西，而是mssql这个扩展，所以，呵呵，上面的事情白做了，从头再来：
