连接到MSSQL DB时出现问题

Question

我有一个Ubuntu 12.04服务器，我正在尝试建立与MSSQL数据库的连接。

我已经设法使用tsql和isql进行连接，但是osql无法正常工作并且使用PDO与PHP连接也无法正常工作..我会尝试尽可能多地提供信息，如果您需要更多信息，请告诉我我会编辑。

freetds.conf ：

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

odbc.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

odbcinst.ini ：

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

〜> isql MSSQL sa传

osql: no IP address found for "TPSACC"

在PHP我有：

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

..要么..

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

他们都返回这个错误：

SQLSTATE[HY000] Unable to connect: Adaptive Server is unavailable or does not exist (severity 9) 

我被困在这里几天，并不能完全弄清楚为什么只有一半的连接实际工作..

任何和所有的帮助真的很感激，谢谢！

编辑：这不同于那个问题，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从1433改变了。我的也被改变了，我修复了，端口现在是54488，因为改变了tsql和isql一直在工作。 但是，它仍然无法解决osql和PHP问题。

osql在你的配置中窒息。 osql是一个调试工具，它只是检查你的配置，然后传递到unixODBC的isql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，你确定这是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; 示例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。 虽然使用“8.0”不应该破坏任何东西，但使用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！
