AWS EC2：（连接被拒绝）同时连接到上游

Question

Error:

2022/02/25 05:25:23 [error] 16292#16292: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.9.17, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:5000/", host: "172.21.11.88"

It's my first time uploading a fullstack JAR file in AWS EC2. Jar file contains Thymleaf web pages and the main java codes.

I've also done setting my RDS in AWS as well.I changed the security group to 'allow access' anywhere so I can connect to it on my local MySQL Workbench. By this, Im done setting up my SQL tables.

So I uploaded the JAR file. The status went from Healthy to Severe. When I access the URL of my app I get this:

application.properties

server.port=5000

AWS Security Group

Inbound Rules

Health Monitoring

UPDATE:

Here's where Im at

Is this what's causing my errors?

Answer 1

By default EB expects your app to listen on port 5000. From docs :

By default, Elastic Beanstalk configures the nginx proxy to forward requests to your application on port 5000. You can override the default port by setting the PORT environment property to the port on which your main application listens.
