FreeTDS工作正常，但是ODBC无法连接 [英] FreeTDS working, but ODBC cannot connect

问题描述

我正在尝试从具有FreeTDS和unixODBC的Ubuntu 12.04网络服务器上运行到MSSQL服务器的连接.

I am trying to run connect to a MSSQL server from an Ubuntu 12.04 webserver with FreeTDS and unixODBC.

使用tsql我可以通过以下方式连接到服务器

Using tsql i can connect to the server with

~$ tsql -S dbs3 -U <username> -P <password>

没问题.

但是，当我尝试与isql连接时，出现以下错误消息:

When I try to connect with isql however, I get the following error message:

~$ isql -v database3 <username> <password>
[S1000][unixODBC][FreeTDS][SQL Server]Unable to connect to data source
[01000][unixODBC][FreeTDS][SQL Server]Unknown host machine name.
[ISQL]ERROR: Could not SQLConnect

我的配置文件如下:

odbc.ini

[database3]
Driver=FreeTDS
TDS_Version=8.0
Servername=dbs3
Port=1433
Database=benchmark_res

odbcinst.ini

odbcinst.ini

[FreeTDS]
Description=FreeTDS v0.91
Driver=/usr/local/lib/libtdsodbc.so
Setup=/usr/local/lib/libtdsS.so
Trace=Yes
TraceFile=/tmp/freetds.log
ForceTrave=Yes
UsageCount=1

freetds.conf

freetds.conf

# This file is installed by FreeTDS if no file by the same
# name is found in the installation directory.
#
# For information about the layout of this file and its settings,
# see the freetds.conf manpage "man freetds.conf".

# Global settings are overridden by those in a database
# server specific section
[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

[dbs3]
    host = <server-ip>
    port = 1433
    tds version = 8.0

我遵循了安装指南1.此处和2 .此处

I followed the installation guide 1. here and 2. here

isql为什么不能正确连接?
我的猜测是该错误非常明显，但我太愚蠢而看不见它:D

Why isn't isql connecting properly?
My guess is that the mistake is super obvious but I'm just too stupid to see it :D

推荐答案

问题是odbc.ini中的这一行

The issue was this line in odbc.ini

[database3] must be [dbs3] in your case.

对于那些也有此问题的人，也请检查

For those that are also having this problem, Check also the

ServerName  = *Points to the name of the server configured in freetds.conf*
