AWS Elastic Beanstalk 上的 Resque

Question

我在使用在 64 位 Amazon Linux 2/3.4.3 平台上运行的 Ruby 2.7 上启动 AWS Elastic Beanstalk 上的 Resque 时遇到问题。我的Procfile如下：

Procfile：

web: bundle exec puma -C /opt/elasticbeanstalk/config/private/pumaconf.rb
worker: RACK_ENV=production BACKGROUND=yes QUEUE=* PIDFILE=/var/pids/worker.pid bundle exec rake resque:work

工作进程启动后不断被杀死。我在 resque.log 中没有收到任何错误消息。我收到的错误消息如下：

我可以使用相同的命令手动启动 resque，然后环境为“绿色”并且可以工作：

eb ssh
[ec2-user@ip-172-31-23-44 current]$ sudo su -

自动生成的worker.service 文件为：

Answer 1

问题出在 Resque 的 BACKGROUND=true 选项上。要使其与 AWS ElasticBeanstalk 一起使用，只需将您的 Procfile 更改为：

web: bundle exec puma -C /opt/elasticbeanstalk/config/private/pumaconf.rb
worker: bundle exec rake resque:work

并确保您没有在任何地方设置后台环境变量。
