安装pymssql模块：

centos :

　　　　yum install python-devel python-setuptools

去https://pypi.python.org/pypi/pymssql/2.1.0  下载源码包  wget https://pypi.python.org/packages/source/p/pymssql/pymssql-2.1.0.tar.gz#md5=e955442a8cd43456cdf5c28b75147afb

yum install freetds-devel

python setup.py build

python setup.py install

一定要装freetds-devel ，不然编译会报gcc的错。

正确编译以后应该可以在python 中import pymssql。

print 'connect ok....'

cursor = conn.cursor()

sql = 'select count(*) from sys.dm_exec_connections'

cursor.execute(sql)

row = cursor.fetchone()

print (row[0])

conn.close()
