[英]Embedded Tomcat won't listen to port 80 in AWS Elastic Beanstalk
I'm launching a Spring Boot .jar with Embedded Tomcat to an Elastic Beanstalk (Java) instance. 我正在使用嵌入式Tomcat将Spring Boot .jar发布到Elastic Beanstalk(Java)实例。
server.port=80 in the configuration file, however EB won't let Tomcat bind to port 80. 配置文件中的server.port = 80,但EB不会让Tomcat绑定到端口80。
What's preventing Tomcat from listening to port 80 and how do I fix it? 是什么阻止了Tomcat监听端口80以及如何解决?
Here's the pertinent section of the logs: 这是日志的相关部分:

Description:
The Tomcat connector configured to listen on port 80 failed to start. The port may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's listening on port 80, or configure this application to listen on another port.

I assume topic starter already resolved this problem, but I'll post my solution here for the new people who'll be stuck on the same issue. 我认为主题启动器已经解决了这个问题,但我会在这里发布我的解决方案,以解决那些陷入同一问题的新人。
I've made my Spring Boot application accessible from port 80 on AWS Elastic Beanstalk by setting environment property SERVER_PORT to 5000 (you can set it in "Configuration" > "Software Configuration"). 通过将环境属性SERVER_PORT设置为5000,您可以从AWS Elastic Beanstalk上的端口80访问我的Spring Boot应用程序(您可以在“Configuration”>“Software Configuration”中进行设置)。
