使用centos上的freetds连接到ms sql 2005

Question

我在从PHP连接到MS SQL 2005时遇到问题.

我可以从shell连接,使用...

tsql -S 10.0.0.134 -p 1433  -U gareth 

输入一个简单的查询按预期工作...

1> SELECT @@VERSION AS MSSQL_VERSION
2> go
MSSQL_VERSION   
Microsoft SQL Server 2005 - 9.00.4035.00 (Intel X86) 
Nov 24 2008 13:01:59 
Copyright (c) 1988-2005 Microsoft Corporation
Express Edition on Windows NT 6.1 (Build 7601: Service Pack 1)

但是,从PHP脚本尝试此操作不起作用...

$test = mssql_connect('10.0.0.134:1433', 'gareth', 'mypass');

...并生成一个mssql_connect()[function.mssql-connect]:无法连接到服务器错误.

我可以看到/ usr/lib/php/modules中的mssql.so模块和phpinfo()显示模块已加载.

如果有人能给我看一下freetds.conf和odbc.conf的示例配置,我很乐意使用odbc_connect

谢谢

这是我在PHP.net上可以找到的有关您的问题的内容.也许它会帮助你解决它.

This might be obvious to some, but here is a quick tidbit that might save you some time if you are using FreeTDS in Linux:
Be sure that you have these two lines in freetds.conf:
dump file = /tmp/freetds.log
dump file append = yes

so you can tail -f it in the background of debugging the problem.  This helped me find my issue on on CentOS Linux: 

1) tsql test works

2) php-mssql connection in php also works WHEN RUN FROM THE SHELL

3) running PHP through apache does NOT work.

my /tmp/freetds.log file told me: 
net.c:168:Connecting to MYDBSERVER port MYDBPORT
net.c:237:tds_open_socket: MYDBSERVER:MYDBPORT: Permission denied

and the answer was my firewall/SELinux was denying the Apache processes access to connect to the remote MSSQL DB port, but my shell accounts were fine.
