【问题描述】：

我正在尝试在 Linux 系统上使用 PHP 连接到 MSSQL DB。

使用tsql -S <dbConfig> 或tsql -H <dbHost> 成功连接到数据库（当然是使用用户凭据）。但是，在 PDO 中使用相同的主机和配置会返回连接到主机适配器失败的错误。

问题似乎存在于 PHP PDO 和我假设是 freetds 之间。

调试看起来像这样：

 PDOException in Connector.php line 55:
 SQLSTATE[01002] Adaptive Server connection failed (MYHOST.database.windows.net) (severity 9)
        in Connector.php line 55

at PDO->__construct('dblib:host=MYHOST.database.windows.net;dbname=RecipeDB;charset=utf8', 'MYUSER@MYHOST', 'MYPASSWORD', array('0', '2', '0', false)) in Connector.php line 55
at Connector->createConnection('dblib:host=MYHOST.database.windows.net;dbname=RecipeDB;charset=utf8', array('driver' => 'sqlsrv', 'host' => 'MYHOST.database.windows.net', 'database' => 'RecipeDB', 'username' => 'MYUSER@MYHOST', 'password' => 'MYPASSWORD', 'charset' => 'utf8', 'prefix' => '', 'name' => 'remoteRecipes'), array('0', '2', '0', false)) in SqlServerConnector.php line 32
at SqlServerConnector->connect(array('driver' => 'sqlsrv', 'host' => 'MYHOST.database.windows.net', 'database' => 'RecipeDB', 'username' => 'MYUSER@MYHOST', 'password' => 'MYPASSWORD', 'charset' => 'utf8', 'prefix' => '', 'name' => 'remoteRecipes')) in ConnectionFactory.php line 61

【解决方案1】：

看来我已经设法从 /etc/freetds.conf 文件中删除了包含 [global] 的行。一旦我替换它，PDO 就能够调用数据库。

下面是我的样子：

[global]
# TDS protocol version
 ; tds version = 4.2
 tds version = 8.0
 client charset = UTF-8

# Whether to write a TDSDUMP file for diagnostic purposes
# (setting this to /tmp is insecure on a multi-user system)
   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

[testConnection]
    host = MYHOST.database.windows.net
    port = 1433
    tds version = 8.0
