Ruby on rails &引用；[unixODBC][FreeTDS][SQL Server]无法连接到数据源“；

当我的应用程序启动时，我收到一个ODBC错误：

ODBC:：错误
S1000（0）[unixODBC][FreeTDS][SQL Server]无法连接到数据源
Rails.root:/var/www/html/TEST\u APP

我正在使用Linux RHEL5+apache和passenger+MSSQL Server 2008

文件数据库.yml：

开发：
适配器：sqlserver
dsn:MSSQL
主机：ip地址
港口：1433
模式：odbc
数据库：mydatabasename
用户名：myusername
密码：mypassword

文件freetds.conf：

[MSSQL]
主机=ip地址
端口=1433
tds版本=8.0
客户端字符集=UTF-8

文件odbc.ini：

[MSSQL]
驱动程序=MSSQL
Description=通过FreeTDS的ODBC连接
Servername=MSSQL
端口=1433
Database=mydatabasename
用户名=我的用户名
Password=mypassword

文件odbc.ini：

[MSSQL]
Description=用于mssql
Driver=/usr/local/lib/libtdsodbc.so
Setup=/usr/lib64/libtdsS.so
FileUsage=1

isql工作原理：

#isql-v MSSQL myusername mypassword
+---------------------------------------+
|连接|
|                                       |
|sql语句|
|帮助[表格名称]|
|退出|
|                                       |
+---------------------------------------+
SQL>

tsql也可以工作：

#tsql-S MSSQL-U myusername-P mypassword
区域设置为“en_US.UTF-8”
区域设置字符集为“UTF-8”
使用默认字符集“UTF-8”
