Laravel连接到SQL Server 2008命名实例

Question

我正在尝试从Ubuntu机器连接一个SQL服务器,除了命名实例之外,每个方法都很好用:

这很有效

'data' => array(
            'driver'   => 'sqlsrv',
            'host'     => 'xxxx',
            'port'     => 1433,
            'database' => 'db',
            'username' => 'user',
            'password' => 'pwd',
            'prefix'   => '',
        ),

这不

  'data' => array(
                'driver'   => 'sqlsrv',
                'host'     => 'yyyy\NAMEDINSTANCE',
                'port'     => 1433,
                'database' => 'db',
                'username' => 'user',
                'password' => 'pwd',
                'prefix'   => '',
            ),

我总是最终得到这个错误:

exception 'PDOException' with message 'SQLSTATE[HY000] Unknown host machine name (severity 2)' in /var/www/public/my.api/vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php:47

我尝试了所有可能的组合:

• 主持人\ INSTANCE
• 主持人/实习
• 主持人\\实例

有人能帮我吗 ？

编辑:因为我也尝试过没有实例名称(如此处所述),脚本继续尝试连接,直到我收到此错误:

exception 'PDOException' with message 'SQLSTATE[HY000] Unable to connect: Adaptive Server is unavailable or does not exist (severity 9)' in /var/www/public/my.api/vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php:47

任何编辑器如Management Studio,DBeaver或Database.NET只能通过指定INSTANCENAME连接到该实例,因此它似乎更像是DSN的PDO问题

我也试图直接连接到那个命名实例而tsql没有任何运气:

tsql -S SERVER -U usr -P pwd -L dbname

这里的/etc/freetds.conf文件:

[global]
        tds version = 8.0
        client charset = UTF-8
        port = 1433
        dump file = /tmp/freetds.log
        dump file append = yes
        text size = 64512

[SERVER]
        host = ip
        port = 1433
        instance = instance_name

[SERVER2]
        host = ip
        port = 1433

和tds日志文件:

log.c:196:Starting log file for FreeTDS 0.91
        on 2015-03-19 15:35:46 with debug flags 0x4fff.

util.c:384:tdserror: returning TDS_INT_CANCEL(2)
mem.c:615:tds_free_all_results()

当然,如果我尝试连接到SERVER2(这是一个非命名实例),一切顺利......

Answer 1

我终于找到了解决方案,有两个问题:

• SQL服务器没有监听好的默认端口(我的坏)
• Laravel(PDO？)不知道如何处理(或者至少我没有找到)命名实例,我尝试过任何可能的组合(参见问题)

所以我最终使用了FreeTDS DSN和laravel的组合来连接SQL命名实例服务器.

该/etc/freetds.conf DSN配置:

[NAMED_INSTANCE]
   host = 127.0.0.1
   port = 55021

在laravel数据库适配器中:

'webcmd' => array(
    'driver'   => 'sqlsrv',
    'host'     => 'NAMED_INSTANCE',
    'database' => 'db',
    'username' => 'usr',
    'password' => 'pwd',
    'prefix'   => '',
),

这解决了我的问题,希望它也会帮助别人
