ElasticBeanstalk worker cron 每分钟运行多次答案

【问题标题】：ElasticBeanstalk worker cron running multiple times per minuteElasticBeanstalk worker cron 每分钟运行多次

【问题描述】：

我有一个运行 Laravel 的 EB 工作环境（单实例），用于运行计划和分派的作业。

我面临的问题是每分钟多次调用 cron，导致计划的作业加倍。这可以在worker的访问日志中看到；

导致我的 CloudWatch 日志中出现类似的重复；

我正在使用dusterio/laravel-aws-worker 与 SQS 队列交互以处理分派的作业。

工人在cron.yaml中有以下内容；

version: 1
cron:
    - name: "schedule"
      url: "/worker/schedule"
      schedule: "* * * * *"

我的工作人员的控制台内核正在安排这样的每小时作业；

protected function schedule(Schedule $schedule)
{
    $schedule->job(new ImportData())
        ->hourly()
        ->timezone(config('app.timezone')); // Pacific/Auckland
}

这里有什么我遗漏的吗？

【解决方案1】：

对于那些偶然发现这个问题的人来说，问题是 HTTPS 重定向发生在我的应用程序上，并且同一个应用程序同时部署到 Web 层和工作层。 302 响应会导致 SQS 重试到您的最大重试次数限制，但每个调用仍在执行作业。

一种解决方案是从该重定向中排除 SQS 代理；

files:
    /etc/httpd/conf.d/http-redirect.conf:
        mode: "000644"
        owner: root
        group: root
        content: |
            RewriteEngine On
            RewriteCond %{HTTP:X-Forwarded-Proto} !https
            RewriteCond %{HTTP_USER_AGENT} !ELB-HealthChecker
            RewriteCond %{HTTP_USER_AGENT} !aws-sqsd
            RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

另一种方法是防止将此脚本部署到工作环境。
