Question

我有一台Ubuntu 12.04服务器，我试图建立与MSSQL数据库的连接。

我已设法使用stdin, stdout, stderr = channel.exec_command("python myScript.py") stdin.close() for line in iter(lambda: stdout.readline(2048), ""): print(line, end="")和tsql进行连接，但isql无法正常工作，并且使用PDO与PHP连接也无法正常工作。我会尝试提供尽可能多的信息，如果你需要更多信息，请告诉我，我会编辑。

freetds.conf ：

osql

ODBC.INI ：

[MSSQL]
  host = TPSACC
  port = 54488
  tds version = 8.0

ODBCINST.INI ：

[MSSQL]
Description     = MS SQL connection to PRODUCTION database
Driver          = FreeTDS
Database        = PRODUCTION
Server          = TPSACC
UserName        = sa
Password        = pass
Trace           = No
TDS_Version     = 8.0
Port            = 54488

〜＆GT; isql MSSQL sa pass

[FreeTDS]
Description = ODBC for Microsoft SQL
Driver      = /usr/local/lib/libtdsodbc.so
UsageCount  = 1
Threading   = 2

〜＆GT; tsql -S MSSQL -U＆＃39; sa＆＃39; -P＆＃39;通过＆＃39;

在PHP中我有：

"Server" found, not using freetds.conf
Server is "TPSACC"
osql: no IP address found for "TPSACC"

.. ..或

$conn = new PDO ("dblib:host=TPSACC;dbname=PRODUCTION","$username","$pw");

他们都返回了这个错误：

$conn = new PDO ("dblib:host=TPSACC;port=54488;dbname=PRODUCTION","$username","$pw");

我已经被困在这里几天了，并且无法弄清楚为什么只有一半的连接确实有效..

非常感谢任何和所有帮助，谢谢！

编辑：与问题不同，我在评论中解释但会在此处重新发布：

对于那个问题是端口是从1433更改的。我的也被更改了，我修复了，端口现在是54488，因为更改tsql和isql一直在工作。但是，它仍然没有解决osql和PHP问题。

osql在你的配置中窒息。 osql是一个调试实用程序，它只是检查您的配置，然后传递给unixODBC的isql以连接（http://linux.die.net/man/1/osql）。试试你的odbc.ini：

[MSSQL]
Driver = FreeTDS
Description = MS SQL connection to PRODUCTION database
Server = tpsacc.yourfulldomain.com
Port = 54488
TDS_Version = 7.2
Database = PRODUCTION
UserName = sa
Password = pass
Trace = No

另外，你确定它是libtdsodbc.so的正确位置吗？当我使用Ubuntu 14 x64（utopic）安装freetds-dev时，它将安装到/usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so;例如odbcinst.ini：

[FreeTDS]
Description = v0.91 with protocol v7.2
Driver = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so

为了更好的衡量，我使用的典型freetds.conf：

# A typical Microsoft server
[MSSQL]
host = tpsacc.yourfulldomain.com
port = 54488
tds version = 7.2

FreeTDS仅支持大多数语言的TDS 7.2版。在使用＆＃34; 8.0＆＃34;不应该破坏任何东西，使用7.2更好的一致性。如果你需要检查参考，我有一个Vagrant盒子，里面有完整的配置，例如：https://github.com/FlipperPA/django-python3-vagrant/祝你好运！
