Question

我在php上编写了一个自定义应用程序，它与数据库连接。如果我在Windows wamp服务器上运行它，应用程序将与数据库连接正确。如果我在ubuntu apache2上运行它，我收到以下错误：

<b>Warning</b>:  mysqli::real_connect(): (28000/1045): Access denied for user 'user'@'localhost'
 (using password: YES) in <b>/var/www/html/reportCMS/php/classes/Database.class.php</b> on line <b>137
</b><br />
<br />
<b>Warning</b>:  mysqli::set_charset(): invalid object or resource mysqli
 in <b>/var/www/html/reportCMS/php/classes/Database.class.php</b> on line <b>141</b><br />
<br />
<b>Warning</b>:  mysqli::prepare(): invalid object or resource mysqli
 in <b>/var/www/html/reportCMS/php/classes/Database.class.php</b> on line <b>829</b><br />
<br />
<b>Fatal error</b>:  Problem preparing query (SELECT id,username,password,type from user WHERE BINARY
 username=? AND active=1 ) Access denied for user 'user'@'localhost' (using password: YES) in <b
>/var/www/html/reportCMS/php/classes/Database.class.php</b> on line <b>830</b><br />

Database.class.php第137行是：

$this->_mysqli = mysqli_init();
$this->_mysqli->real_connect( $this->host, $this->username, $this->password, $this->db, $this->port );
$this->_mysqli->set_charset ('utf8');

在两种情况下与数据库的连接都在使用mysql的ubuntu机器上。

你能指导我，如何找到错误？如果您需要更多信息，请告诉我。

修改唯一的区别在于权限的配置文件，在ubuntu上是localhost。在Windows机器上是ubuntu的IP。但是我已经为myshost上的localhost和％授予了权限。

最后我解决了。我的错误是在Windows上创建了配置文件（用户名，密码，db）。因为在文件上插入了一些空格，我将它与Netbeans一起从Ubuntu中删除它并且它有效。
