Node.js Adonis-502弹性豆茎上的坏网关

我正在尝试在Elastic Beanstalk上部署AdonisJS应用程序。我已经按照几个教程进行了操作，但我得到了502坏网关：(

我已经按照所有教程中的建议，从配置门户将

PORT

env变量设置为8081

----------------------------------------
/var/log/nginx/error.log
----------------------------------------
2020/12/28 19:54:52 [error] 5218#0: *266 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.xxx.xx, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8081/", host: "172.xx.xx.x"

请提供帮助，因为它现在变得非常令人沮丧：(

谢谢

使用

0.0.0.0

作为

HOST

变量。 出现错误是因为应用程序不可访问。请设置

HOST=0.0.0.0

，使服务器侦听所有接口

---

您可以在此处查看有关

0.0.0.0

的更多详细信息：

您的

HOST

变量是否设置为

0.0.0

？@crbast否。我应该将其设置为0.0.0.0吗？@crbast您是一个救生员！非常感谢，它成功了：）@crbast您还可以告诉我如何在环境中执行

节点ace迁移：运行

。我在.ebextensions文件夹下有一个脚本，但在使用该脚本时部署失败。没有脚本，一切都很好，但数据库无法工作，因为没有表。谢谢！我很高兴它可以工作：）对于您的第二个问题，请打开一个带有日志详细信息的新问题（我很乐意回答）。谢谢，我正在迁移到EC2，Elastic beanstalk有很多问题，一旦我得到部署错误，即使我恢复应用程序的旧工作版本，它也不会得到修复。我不知道EC2，但尝试删除完整应用程序并重试完整部署EC2工作正常。
