连接到 MSSQL DB 的问题

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 不起作用并且使用PDO 连接PHP 也不起作用.. 我会尽力提供尽可能多的信息如果您需要更多信息，请告诉我，我会进行编辑。

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 通

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

在 PHP 中我有：

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

..或..

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

我在这里被困了几天，无法弄清楚为什么只有一半的连接真正有效..

非常感谢任何和所有帮助，谢谢！

编辑：这与那个问题不同，我在评论中解释过，但会在这里重新发布：

对于那个问题，问题是端口从 1433 更改了。我的也更改了，我修复了这个问题，端口现在是 54488，并且由于更改，tsql 和 isql 一直在工作。但是还是没有解决osql和PHP的问题。

Answer 1

osql 被您的配置中的某些东西窒息。 osql 是一个调试实用程序，它只检查您的配置，然后传递给 unixODBC 的 isql 进行连接 (http://linux.die.net/man/1/osql)。为您的 odbc.ini 试试这个：

[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，您确定这是 libtdsodbc.so 的正确位置吗？当我使用 Ubuntu 14 x64 (utopic) 安装 freetds-dev 时，它会安装到 /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

为了更好地衡量，我使用的典型 freetds.conf：

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

FreeTDS 最多仅支持大多数语言的 TDS 版本 7.2。虽然使用“8.0”不应该破坏任何东西，但使用 7.2 更好地保持一致性。如果您需要查看参考，我这里有一个完整配置的 Vagrant 框，示例：https://github.com/FlipperPA/django-python3-vagrant/Good lucky！
