Magento 2 update.log每分钟都会增加大量文件

更新：

我最终使用logrotate实用程序来处理不断增长的日志文件。我还设置了一些cron作业，这些作业将不时检查不需要的临时文件。

我已经配置并运行了标准的Magento 2 cron。两天后，在“管理”面板中运行某些操作时遇到了一些问题。当检查服务器日志时，我发现这是磁盘空间问题。经过进一步调查，我发现这update.log.txt是罪魁祸首。文件大小每分钟增加> 1MB。曾经有一段时间它达到了20GB以上。

标准Magento 2设置正常吗？还是可以＆如何禁用它或至少将其最小化？

它同时发生在开发人员模式和生产模式中。

Cron设置基于此指南。

Cron标签：

* * * * * <path to php binary> <magento install dir>/bin/magento cron:run | grep -v "Ran jobs by schedule" >> <magento install dir>/var/log/magento.cron.log
* * * * * <path to php binary> <magento install dir>/update/cron.php >> <magento install dir>/var/log/update.cron.log
* * * * * <path to php binary> <magento install dir>/bin/magento setup:cron:run >> <magento install dir>/var/log/setup.cron.log

更新：

我最终使用logrotate实用程序来处理不断增长的日志文件。我还设置了一些cron作业，这些作业将不时检查不需要的临时文件。

据我所知，该var/log/update.log文件确实与cron一起使用。

声明在 \setup\src\Magento\Setup\Model\Cron\Status.php

$this->logFilePath = $logFilePath ? $logFilePath : DirectoryList::LOG . '/update.log';

然后通过该getLogFilePath()方法进行检索。

如果检查此方法的调用位置，则位于\setup\src\Magento\Setup\Model\Cron\JobFactory.php：

$logStream = fopen($cronStatus->getLogFilePath(), 'a+');
$streamOutput = new MultipleStreamOutput([$statusStream, $logStream]);

然后将该$streamOutput变量作为参数传递给作业类，例如：

return new JobUpgrade(
    $this->serviceLocator->get('Magento\Setup\Console\Command\UpgradeCommand'),
    $objectManagerProvider,
    $streamOutput,
    $this->serviceLocator->get('Magento\Setup\Model\Cron\Queue'),
    $cronStatus,
    $name,
    $params
);

如果继续讲这个示例，$this->output则在execute()方法中使用：

$this->command->run(new ArrayInput($this->params), $this->output);

该run()方法在中声明vendor\symfony\console\Symfony\Component\Console\Command\Command.php

$output然后在多个地方使用该变量，例如：

    $this->initialize($input, $output);

以及 ：

    if ($input->isInteractive()) {
        $this->interact($input, $output);
    }

    $input->validate();

    if ($this->code) {
        $statusCode = call_user_func($this->code, $input, $output);
    } else {
        $statusCode = $this->execute($input, $output);
    }

另一个有趣的是：

        } elseif (OutputInterface::VERBOSITY_VERY_VERBOSE === $output->getVerbosity()) {
            $output->writeln('<comment>Install the proctitle PECL to be able to change the process title.</comment>');
        }

根据最后的代码，在参数非常冗长的情况下可以编写一些东西。也许您使用设置了cron作业，-vv这就是为什么东西被记录的原因。

这不是一个确定的答案，但是您应该遵循我刚刚给您提供的堆栈跟踪来调查问题。

您可能在某些文件夹上设置了错误的权限。/ update / cron列出所有具有错误权限的文件夹

简单的方法就是在crontab更新和设置中注释掉

#* * * * * <path to php binary> <magento install dir>/update/cron.php >> <magento install dir>/var/log/update.cron.log
#* * * * * <path to php binary> <magento install dir>/bin/magento setup:cron:run >> <magento install dir>/var/log/setup.cron.log

如果不需要从管理面板更新和安装，则不需要它们。

对于生产服务器来说，这是一个危险的主意。您可以通过测试/本地服务器上的composer手动更新；测试；然后将更新复制到生产服务器。

您真正需要的是

* * * * * <path to php binary> <magento install dir>/bin/magento cron:run | grep -v "Ran jobs by schedule" >> <magento install dir>/var/log/magento.cron.log

它管理“索引器，发送自动电子邮件，生成站点地图等”-如devdocs中所述

/var/log/update.log是cron日志文件，当您有文件时，尤其会出现此问题permission issue。“这就是我打开该文件时遇到的情况。”

这可能是解决方法：https : //community.bitnami.com/t/update-log-file-grows-rapidly-in-magento-2-1-1/49253/6

您需要为Magento目录和文件设置正确的权限和所有权。

据我所知update.log是您的自定义日志文件，因为Magento 2会生成此类文件

• var / log / debug.log –由Psr \ Log \ LoggerInterface :: debug（）保存的所有信息都存储在此处。
• var / log / exception.log –所有异常信息都存储在此处。
• var / log / system.log-其他日志记录级别的信息保存在此处。

我不确定为什么它会在文件中生成大量日志数据，可能是语法错误或类似的错误。

但是我建议您只update.log在您的Magento 2代码目录中使用with进行搜索，然后从您的代码中删除该日志。
