unixODBC 和 FreeTDS 配置问题

Question

我已经为此工作了太久，似乎无法弄清楚。我确定我的 freetds.conf、odbc.ini 或 odbcinst.ini 有问题。我可以使用 tsql 连接到我的 mssql 2008 服务器，但仍然无法使用 isql 或当然通过 php。

我在 CentOS 5.6 上。

谁能提供一些帮助？

谢谢！ 肖恩

这是在我的 sqltrace.log 中：

Answer 1

看起来 FreeTDS 中的版本号已从 8.0 更改为 7.1，从 9.0 更改为 7.2。 见http://www.freetds.org/userguide/choosingtdsprotocol.htm

Answer 2

查看您的 sqltrace.log，它在我看来就像一个身份验证错误 - 您在身份验证后立即收到“来自服务器的意外 EOF”消息...

远程服务器是否有可能完全或在端口 1433 上阻止来自您的 CentOS 服务器的连接？您的 freetds.conf 中的“client charset = UTF-8”是否有可能导致问题？

这是我在 Ubuntu 12.04（Precise Pangolin）机器上的（工作）设置。

这是我的 /etc/odbc.ini 文件：

[xyz]
Description             = XYZ Server
Driver                  = freetds
Database                = MyDB
ServerName              = xyz
TDS_Version             = 8.0

还有我的 /etc/odbcinst.ini 文件：

[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

最后是我的 /etc/freetds/freetds.conf 文件：

[global]
        # TDS protocol version
;       tds version = 4.2

        # Whether to write a TDSDUMP file for diagnostic purposes
        # (setting this to /tmp is insecure on a multi-user system)
;       dump file = /tmp/freetds.log
;       debug flags = 0xffff

        # Command and connection timeouts
;       timeout = 10
;       connect timeout = 10

        # If you get out-of-memory errors, it may mean that your client
        # is trying to allocate a huge buffer for a TEXT field.  
        # Try setting 'text size' to a more reasonable limit 
        text size = 64512

# A typical Sybase server
[egServer50]
        host = symachine.domain.com
        port = 5000
        tds version = 5.0

# A typical Microsoft server
[egServer70]
        host = ntmachine.domain.com
        port = 1433
        tds version = 7.0

# The XYZ database
[xyz]
        host = XYZ
        port = 1433
        tds version = 8.0
