我已经安装了 freetds，我想通过 php 连接到 mssql 服务器。我正在使用centos。

root@server [~/php]# tsql -C
Compile-time settings (established with the "configure" script)
                            Version: freetds v0.91
             freetds.conf directory: /usr/local/etc
     MS db-lib source compatibility: no
        Sybase binary compatibility: no
                      Thread safety: yes
                      iconv library: yes
                        TDS version: 5.0
                              iODBC: no
                           unixodbc: yes
              SSPI "trusted" logins: no
                           Kerberos: no

我用来连接到 mssql 服务器的 php 代码。（它位于子目录中）我能够通过本地 mssql 服务器 2008 连接到远程 mssql 服务器。

<?php
// Older FreeTDS installations need the FREETDSCONF Environment variable
putenv('FREETDSCONF=../usr/local/etc/freetds.conf');
// Current release of FreeTDS uses the FREETDS environment variable. So we set both to be sure
putenv('FREETDS=../usr/local/etc/freetds.conf');
$mssql = mssql_connect('116.214.26.236' , 'dbname', 'password');
//mssql_select_db('myDb',$mssql);


if (!$mssql) {
    die('Something went wrong while connecting to MSSQL');
}else echo 'Success';

?>

我的 TDS 配置文件

#   $Id: freetds.conf,v 1.12 2007/12/25 06:02:36 jklowden Exp $

# This file is installed by FreeTDS if no file by the same

    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 = 116.214.26.236
    port = 1433
    tds version = 7.0

我得到的错误

警告：mssql_connect() [function.mssql-connect]：无法连接到服务器：第 6 行 /home/butter/public_html/investonline/mssql.php 中的 116.214.26.236 连接到 MSSQL 时出现问题

请指导我哪里出错了。

我在谷歌上搜索了一些博客说下面的行值必须是 yes，MS db-lib 源兼容性：否

我的 php.ini 配置文件

mssql
MSSQL Support   enabled
Active Persistent Links 0
Active Links    0
Library version FreeTDS

Directive   Local Value Master Value
mssql.allow_persistent  On  On
mssql.batchsize 0   0
mssql.charset   no value    no value
mssql.compatability_mode    Off Off

mssql.secure_connection On  On
mssql.textlimit Server default  Server default
mssql.textsize  Server default  Server default
mssql.timeout   60  60

还让我知道我应该如何获取日志，以便我可以知道在哪一步出现错误。

还有为什么我无法连接到 mssql 服务器。

您可以使用 PDO php 库与 sql server 连接，您可以像这样使用 $output = new PDO ('mssql:host=SERVERHOST;dbname=DBNAME','DBUSERNAME','DBPASSWORD');

得到这个链接并按照它说的做。最好只使用微软的驱动程序。
