我已经将问题更新了几次，但原始问题基本保持不变，因此我的思考过程更容易理解。我已经为每个人添加了一个简短的摘要，以决定他们是否能够在这方面提供帮助。任何帮助都是非常感谢的。

摘要

  • 错误很少发生(每2-4周发生一次)。
  • 错误发生后，每隔一次访问数据库的请求也会崩溃，并出现相同的错误
  • 在创建MySqlConnector时出现的错误似乎只发生在此应用程序的实时服务器上，因此我们不能离开该错误并开始调试，而是必须对其进行热修复以保持正常运行时间。
  • 我们确实遇到了一些连接随机断开(很少)的问题。这几乎是在同一时刻开始的。也许问题是在建立PDO连接时连接断开了？

堆栈

  • Apache 2.4.32
  • PHP Apache 10.2.6

详细问题

我们在其中一个laravel项目中遇到了以下错误：

一旦这个错误第一次发生，所有对网站的请求都会触发完全相同的错误。

在谷歌上搜索这个问题，我发现了以下两个解决方案：

run php artisan config:cache or php artisan config:clear

  • restart
  1. php artisan config:cache

(运行web服务器或运行web服务器

找到这些解决方案的一个示例可以在here找到

现在重启web服务器起作用了，但在一个小时内，同样的问题又出现了。又重新启动了一次，现在看起来是有效的，但我想知道是什么导致了这种情况，以及我们如何防止它发生？

更多信息：

  • 我们使用Redis来缓存包括config.
  • Hosting在内的所有东西都是使用一个自定义的apache堆栈完成的。
  • 这个网站已经运行了几个月，进行了几次重启，但从未遇到过这个问题。
  • 今天第一次出现这个问题时，服务器已经填满了它的内存容量，第二次出现这个问题时，它还剩下15 GB的内存。

任何线索或建议都将不胜感激。如果需要更多的信息来回答这个问题，我会在被问到的时候尝试扩展这个问题。

更新：

所以我们让错误再次发生，相同的行，但不同的错误。我认为在建立PDO连接时出了问题，然后这个连接被存储起来，以便在一段时间内再次用于所有未来的请求？

这是新的堆栈跟踪：

错误行再次出现在来自laravel/framework的ConnectionFactory的第245行。这一行是来自下面函数的return new MySQLConnector;行：

代码语言：javascript
复制
/**
 * Create a connector instance based on the configuration.
 *
 * @param  array  $config
 * @return \Illuminate\Database\Connectors\ConnectorInterface
 *
 * @throws \InvalidArgumentException
 */
public function createConnector(array $config)
{
    if (! isset($config['driver'])) {
        throw new InvalidArgumentException('A driver must be specified.');
    }

    if ($this->container->bound($key = "db.connector.{$config['driver']}")) {
        return $this->container->make($key);
    }

    switch ($config['driver']) {
        case 'mysql':
            return new MySqlConnector;
        case 'pgsql':
            return new PostgresConnector;
        case 'sqlite':
            return new SQLiteConnector;
        case 'sqlsrv':
            return new SqlServerConnector;
    }

    throw new InvalidArgumentException("Unsupported driver [{$config['driver']}]");
}

MySqlConnector类扩展了Connector类。Connecter的前几行是：

代码语言：javascript
复制
<?php

namespace Illuminate\Database\Connectors;

use PDO;
use Exception;
use Illuminate\Support\Arr;
use Doctrine\DBAL\Driver\PDOConnection;
use Illuminate\Database\DetectsLostConnections;

class Connector
{
    use DetectsLostConnections;

    /**
     * The default PDO connection options.
     *
     * @var array
     */
    protected $options = [
        PDO::ATTR_CASE => PDO::CASE_NATURAL,
        PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
        PDO::ATTR_ORACLE_NULLS => PDO::NULL_NATURAL,
        PDO::ATTR_STRINGIFY_FETCHES => false,
        PDO::ATTR_EMULATE_PREPARES => false,
    ];

似乎应该设置PDO::ATTR_CASE。或者可能PDO::CASE_NATURAL也没有设置？我不完全理解到底发生了什么，但在创建新的MySqlConnecter对象或创建底层连接器时，它会返回未设置的错误。首先，我认为这与类中的一些函数有关。但是看到Trace在创建时停止，这意味着错误不可能真正来自任何函数。

所以我认为在使用PDO类时一定出了什么问题？Connecter.php在开头还有下面一行：'use Doctrine\DBAL\Driver\PDOConnection;‘，它也扩展了PDO。

一旦发生这种情况，每个用户的后续请求都会返回相同的堆栈跟踪错误，直到我们重新启动Apache，我完全不理解这一点。似乎在PDO文件不可用的情况下可能会发生这种情况，但我不确定为什么总是发生这种情况，为什么重启Apache可以解决这个问题。

以下是可能有助于解决此问题的子问题：

  1. 是什么原因导致此错误出现？
  2. 如果上面的问题不能轻松回答，我可以做些什么来更好地了解此问题？这种情况在我们的实际环境中很少发生，所以我们没有机会把dd的应用程序放在各处一步一步地进行。而且每次重启Apache时都必须使用快速修复程序。
  3. 为什么在初始失败后的每个请求都会失败，并返回相同的错误？

我们最后一次尝试重启了Apache，以及MySQL。(按此顺序)似乎已经解决了问题。以防我们当晚也重启服务器。

这为我们解决了问题，但如果有人对导致问题的原因有更好的答案，我希望他们能分享他们的知识！

编辑:仍未修复，似乎是临时修复。

到目前为止，这里有三个建议：

  • 确保您的数据库配置设置正确并以这种方式保存(因此在服务器端读取的变量不会发生任何变化...不仅来自.env文件)。这可能与缓存和当前数据库设置之间的某种冲突有关。仔细看一看；
  • 确保你的php版本符合laravel 5.4的要求，因为这种类型的错误很容易由当前php版本中不存在的语法引起，这些语法在某个给定的时间点在后台的某个地方被使用，从那里后台服务器上的工作corrupted;
  • This可能与你正在使用的php版本的PDO PDO驱动程序的可用性有关，所以给定的关于PDO类中的东西的功能片段是不可访问的。对我来说，这听起来很合理，所以你可以更深入地挖掘这个问题。重点关注正在使用的某些PHP和PDO模块的设置。

此外，应该关注服务器端配置错误(如apache或服务器管理)，因为错误输入可能会传递到基本的laravel层，并导致意外行为。不幸的是，堆栈跟踪和错误周围的信息不足以准确地诊断问题。尽管如此，请继续关注，这似乎很有趣。
