你有你需要的所有软件吗？这就是Ubuntu 12.04所需要的：sudo apt-get install php5-odbc php5-sybase tdsodbc

您在Linux服务器上配置了这些文件吗？(这些是从Ubuntu12.04服务器上获取的)

/etc/odbc.ini# Define a connection to the MSSQL server.

# The Description can be whatever we want it to be.

# The Driver value must match what we have defined in /etc/odbcinst.ini

# The Database name must be the name of the database this connection will connect to.

# The ServerName is the name we defined in /etc/freetds/freetds.conf

# The TDS_Version should match what we defined in /etc/freetds/freetds.conf

[mssql]

Description = MSSQL Server

Driver = freetds

Database = MyDatabase

ServerName = mssql

TDS_Version = 8.0

/etc/odbcinst.ini# Define where to find the driver for the Free TDS connections.

[freetds]

Description = MS SQL database access with Free TDS

Driver = /usr/lib/i386-linux-gnu/odbc/libtdsodbc.so

Setup = /usr/lib/i386-linux-gnu/odbc/libtdsS.so

UsageCount = 1

/etc/freetds/freetds.conf# The basics for defining a DSN (Data Source Name)

# [data_source_name]

# host =

# port =

# tds version =

# Define a connection to the MSSQL server.

[mssql]

host = mssql_server_ip_or_domain_name

port = 1433

tds version = 8.0

我读过几篇关于tds版本导致问题的文章。看起来8.0是最好的，但我也看到有人说他们用了7.5和7.0。

然后测试您的连接：isql mssql username password

根据您的环境，您的用户名可能必须采用以下格式：域\用户名

发出命令后，您应该看到如下内容：+---------------------------------------+

| Connected! |

| |

| sql-statement |

| help [tablename] |

| quit |

| |

+---------------------------------------+

SQL>

我认为connect命令应该是这样的(注意：我不知道Python)：cnxn = pyodbc.connect('DRIVER=freetds;SERVER=FOOBAR;PORT=1433;DATABASE=T2;UID=FOO;PWD=bar;TDS_Version=8.0;')
