Question

我有一个UBUNTU LAMP设置。安装了所有必要的扩展

php5-odbc php5-mssql FREETDS unixODBC

从CLI我已经使用isql和tsql测试了我与数据库的连接，两者都正在连接并且工作正常。

这是我的freetds.conf：

    ....
    # A typical Microsoft server
[TS]
        host = 10.32.6.52
        port = 1433
        tds version = 8.0
        client charset = UTF-8

这是我的odbc.ini

[TS]
Description = "XXXXXXX"
Driver = /usr/local/lib/libtdsodbc.so
Server = xxx.xxx.xxx.xxx
Port = 1433
Database = XX_X_XX_XXXXX
Trace = No
TDS_Version = 8.0
[Default]
Driver=/usr/local/lib/libtdsodbc.so

这是我的odbcinst.ini

[FreeTDS]
Description = FreeTDS
Driver = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so
Setup = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so
FileUsage = 1
CPTimeout =
CPResuse  =
client charset = utf-8
UsageCount = 1

这是我的php

<?php

putenv("TDSVER=80");
putenv("FREETDSCONF=/etc/freetds/freetds.conf");
putenv("ODBCSYSINI=/etc/odbcinst.ini");
putenv("ODBCINI=/etc/odbc.ini");


$myServer = "XXX.XXX.XXX.XXX";
$username = "XXXXX";
$password = "XXXXX";
$database = "XXXXX";

//connection to the database
$dbhandle = mssql_connect($myServer, $username, $password)
  or die("Couldn't connect to SQL Server on $myServer");

//select a database to work with
$selected = mssql_select_db($database, $dbhandle)
  or die("Couldn't open database $myDB");

//declare the SQL statement that will query the database
$query = "SELECT title from project where id = 8 ";

//execute the SQL query and return records
$result = mssql_query($query);

$numRows = mssql_num_rows($result);
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>";

//display the results
while($row = mssql_fetch_array($result))
{
  echo "<li>" . $row["title"] . "</li>";
}
//close the connection
mssql_close($dbhandle);
?>

就像我从CLI说的那样我可以连接到SQL服务器，但是从php它不起作用。我已经尝试了所有可以找到的建议，但没有任何对我有用。

这里还有我的Apache错误日志：

找到问题并解决了。我通过取消注释/etc/freetds/freetds.conf

中的日志文件位置来启用Freetds.log

这是日志文件提取

config.c:303:[XXXXXXXXX] not found.
config.c:367:... $FREETDS not set.  Trying $HOME.
config.c:293:Could not open '/var/www/.freetds.conf' ((.freetds.conf)).
config.c:297:Found conf file '/usr/local/etc/freetds.conf' (default).
config.c:483:Looking for section global.
config.c:542:   Found section global.
config.c:545:Got a match.
config.c:567:   text size = '64512'
config.c:542:   Found section egserver50.
config.c:542:   Found section egserver70.
config.c:556:   Reached EOF
config.c:483:Looking for section XXXXXXXXXXXX.
config.c:542:   Found section global.
config.c:542:   Found section egserver50.
config.c:542:   Found section egserver70.
config.c:556:   Reached EOF
config.c:303:[XXXXXXXXXXXX] not found.
config.c:208:Failed in reading conf file.  Trying interface files.
config.c:1042:Looking for server XXXXXXXXXXX....

所以基本上它是在freetds.conf文件中查找我的servername。但我没有指明它。连接信息在配置文件中列为[TS]我更改了我的php信息以查找[TS]并且突然间它工作了

$myServer = "TS";
$username = "XXXXX";
$password = "XXXXX";
$database = "XXXXX";

Answer 2

我只想发布此事件，以帮助其他可能遇到同样问题的人：

最终为我工作的是：将PHP连接字符串中的freetds.conf值更改为我尝试连接的服务器的引用名称，正如我在{{1}中指定的那样}和.odbc.ini，而不是实际的IP地址。

感谢@Stroes指出我正确的方向。经过一个多星期的阅读文章和故障排除后，这个问题几乎让我流下了眼泪。
