AWS上的Laravel计划任务无法正常工作 [英] Laravel Scheduling Task on AWS is not working

问题描述

我正在将我的Laravel应用程序部署到ElasticBeanstalk环境.我正在尝试在服务器上的调度任务"中运行命令.但这是行不通的.这就是我所做的.

I am deploying my Laravel application to ElasticBeanstalk environment. I am trying to run a command in the Scheduling Task on the server. But it is not working. This is what I have done.

我在Kernel.php文件中安排我的命令，如下所示.

I schedule my command in the Kernel.php file as follow.

$schedule->command('counter:update')->everyMinute()->onOneServer();

我正在使用Redis作为缓存驱动程序，并且可以正常工作.

I am using Redis as my cache driver and it is working.

然后我尝试了两种不同的方法.

Then I tried two different approaches.

第一种方法:使用Laravel AWS Worker软件包， https://packagist.org/packages/dusterio/laravel-aws-worker

我按照文档中的说明安装了软件包.

I installed the package following the instructions mentioned in the doc.

然后我将CSRF中间件中文档中提到的工作路由列入白名单.

Then I whitelist the worker routes mentioned in the doc in the CSRF middleware.

然后我在项目的根文件夹中创建了一个cron.yml文件，内容如下.

Then I created a cron.yml file right inside the project's root folder with the following content.

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

然后，我部署了我的应用程序.但是计划"任务无法正常工作.因此，我尝试了以下第二种方法.

Then I deployed my application. But the Scheduling task is not working. So I tried the second approach as follow.

第二种方法:使用Crontab

我创建了一个.ebextensions/cronjob.config文件，其中包含以下内容.

I created a .ebextensions/cronjob.config file with the following content.

files:
    "/etc/cron.d/schedule_run":
        mode: "000644"
        owner: root
        group: root
        content: |
            * * * * * root . /opt/elasticbeanstalk/support/envvars && /usr/bin/php /var/www/html/artisan schedule:run 1>> /dev/null 2>&1

commands:
    remove_old_cron:
        command: "rm -f /etc/cron.d/*.bak"

然后，我部署了我的应用程序.第二种方法也不起作用.配置中缺少什么?如何使它正常工作?

Then I deployed my application. The second approach is not working either. What is missing in my configuration and how can I get it working?

这是我的另一个cronjob.config文件.

This is my another cronjob.config file.

files:
    "/etc/cron.d/mycron":
        mode: "000644"
        owner: root
        group: root
        content: |
            * * * * * root /usr/local/bin/myscript.sh

    "/usr/local/bin/myscript.sh":
        mode: "000755"
        owner: root
        group: root
        content: |
            #!/bin/bash

            date > /tmp/date
            * * * * * root . /opt/elasticbeanstalk/support/envvars && /usr/bin/php /var/www/html/artisan schedule:run 1>> /dev/null 2>&1

            exit 0

commands:
    remove_old_cron:
        command: "rm -f /etc/cron.d/mycron.bak"

推荐答案

您尝试的 cron.yml 仅用于工作环境.

/opt/elasticbeanstalk/support/envvars 仅适用于 Amazon Linux 1 .由于您正在使用运行PHP 7.3的 64位Amazon Linux 2 v3.0.3 (我记得)，因此cron会出错.

The /opt/elasticbeanstalk/support/envvars is only for Amazon Linux 1. Since you are using 64bit Amazon Linux 2 v3.0.3 running PHP 7.3 (as I recall), the cron will error out.

因此，您应该专注于第二种方法，该方法与 AWS博客相一致，说明如何在AL2上使用cron:

Thus, you should focus on the second approach, which is in line with AWS blog on how to use cron on AL2:

• 如何在以下环境中的Amazon EC2实例上创建cron作业弹性Beanstalk环境?

因此，我建议通过博客中显示的脚本(例如，/usr/local/bin/myscript.sh )执行 cron 作业.

Therefore, I would recommend execute cron job through a script (e.g., /usr/local/bin/myscript.sh) as shown in the blog.

/usr/local/bin/myscript.sh 的修改内容.

您只能先尝试 date>/tmp/date 只是为了检查cron作业是否正常.为此，您必须部署应用程序，并检查/tmp/date 是否包含此脚本生成的时间.

You can try first only with date > /tmp/date just to check if the cron job works. For this you have to deploy your application, and check if /tmp/date contains the time generated by this script.

    "/usr/local/bin/myscript.sh":
        mode: "000755"
        owner: root
        group: root
        content: |
            #!/bin/bash

            date > /tmp/date

            # the line below is commented out.
            #/usr/bin/php /var/www/html/artisan schedule:run 1>> /dev/null 2>&1

            exit 0

Amazon Linux 2中的访问环境变量

env变量存储在/opt/elasticbeanstalk/deployment/env

因此要在脚本中加载它们，可以使用以下内容:

Thus to load them in your script you can use the following:

env $(cat /opt/elasticbeanstalk/deployment/env | xargs) sh -c '/usr/bin/php /var/www/html/artisan schedule:run 1>> /dev/null 2>&1'

或两行

export $(cat /opt/elasticbeanstalk/deployment/env | xargs) 
/usr/bin/php /var/www/html/artisan schedule:run 1>> /dev/null 2>&1
