我已经看了一个相关的答案这个问题的负载，但..解决方案仍然没有为我工作！我的代码在localhost测试环境内工作正常，但不在生产环境中。访问拒绝mysqli时推送到生产服务器
这里是我的代码：
<h1> Security clearances Due to Expire</h1>
<?php
$db['user'] = 'prometheus';
$db['password'] = '';
$db['host'] = '*****.manchester.mpl.local';
$ingeniumMySQL = new mysqli($db['host'], $db['user'], $db['password'], "ingenium");
if ($ingeniumMySQL->connect_errno) {
echo "Failed to connect to MySQL: " . $ingeniumMySQL->connect_error;
}
$sqlone="SELECT person_security_levels.clearance_expires_date,
person.forename,
person.surname

where person_security_levels.person_id= person.id and person_security_levels.clearance_expires_date between NOW() AND DATE_ADD(NOW() ,
INTERVAL +3 MONTH)

";
$resultone= mysqli_query($ingeniumMySQL,$sqlone);

我查询数据库来产生HTML表格的结果集。 授予指定用户全部权限 虚拟用户已创建用于在不同帐户上进行测试，并且使用最新的mysqli。
这里是在生产中显示的错误（欣赏任何建议）：
警告：mysqli的:: mysqli的（）[mysqli.mysqli]：（一千〇四十五分之二万八）：访问 拒绝用户“普罗米修斯'@'****。manchester.mpl.local'（使用 password：YES） /storage/www/z-ingenium/application/views/scripts/reports/clearance-expires.phtml on line 7 Failed连接到MySQL：访问拒绝用户 'prometheus'@solutions.manchester.mpl.local'（使用密码：是）
看起来你没有在你的生产服务器上设置密码。尝试删除密码。 –
您是否从命令行验证了MySQL连接？ （意识到在发布之前您可能已经从源代码中删除密码）。 –
您的数据库是否在另一台主机上？数据库服务器的“绑定地址”是否配置为允许远程主机？默认情况下，它只设置为允许从本地主机。 – Rvanlaak
