java - 配置为监听端口 80 的 Tomcat 连接器启动失败

Question

我运行 webapp https://github.com/donhuvy/mycustomer我遇到错误

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.

这是我的日志https://gist.github.com/donhuvy/93210850f955f9ddbc00ab735a0ade18#file-terminal-log-L191

我已经通过命令查看了80端口

sudo lsof -i TCP:80 | grep LISTEN

但结果是什么都没有。如何解决？ (我使用的是 macOS 10.12.5)

更新:

运行 Sencha 客户端(在目录 client 内)

sencha web -port 8082 start

然后我将 Spring Boot 端口更改为 8082:

APPLICATION FAILED TO START

Description:

The Tomcat connector configured to listen on port 8082 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 8082, or configure this application to listen on another port.

Answer 1

在linux上1024以下的端口只有root才能打开，所以默认限制80端口

如果你想在 80 端口上发布你的应用程序，你需要将请求从端口 80 重定向到你将要运行你的 springapp 的端口(例如 8080)

您可以使用默认允许在端口 80 上工作的 apache2 服务器，并且可以将您的请求转发给 tomcat
