php - 连接到 MSSQL 数据库时出现问题

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 不起作用，并且使用 PDO 与 PHP 连接也是'无法正常工作。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 pass

|                                       |

"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) 

我已经被困在这里几天了，无法完全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的帮助，谢谢!

编辑:这与那个问题不同，我在评论中解释过，但会在此处重新发布:

对于那个，问题是端口从 1433 更改了。我的也更改了，我修复了它，端口现在是 54488，自从那个更改 tsql 和 isql 一直在工作。但是，它仍然没有解决 osql 和 PHP 问题。

osql 因配置中的某些内容而阻塞。 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

此外，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 最多只支持 TDS 7.2 版和大多数语言。虽然使用“8.0”应该不会破坏任何东西，但使用 7.2 更利于保持一致性。如果您需要查看引用，我有一个带有完整配置的 Vagrant 盒子，这里有示例:https://github.com/FlipperPA/django-python3-vagrant/祝你好运!
