The Tomcat connector configured to listen on port 80 failed to start

I run webapp https://github.com/donhuvy/mycustomer I face error

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.

This is my log https://gist.github.com/donhuvy/93210850f955f9ddbc00ab735a0ade18#file-terminal-log-L191

I have been check port 80 by command

sudo lsof -i TCP:80 | grep LISTEN

But result is nothing. How to fix it? (I use macOS 10.12.5)

Update:

Run Sencha client (inside directory client)

sencha web -port 8082 start

and I change Spring Boot port to 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.

If you start SpringBoot application with configured port 80, here can be 2 problems:

  1. Need to execute a command with root permissions. Just add "sudo" before the start command. This helped me.

  2. Port is using by another application. To check it, you can use the command: "netstat -l";

On linux ports below 1024 can be opened only by root, so the port 80 is restricted by default

if you want to publish your app on 80 port you need to redirect request from port 80 to the port you gonna run your springapp (e.g 8080) port

you can use apache2 server wich is allowed by default to work on port 80 and can forward requests for you to tomcat

80 port is already use by another application. change the post no of tomcat. and you can not run tomcat on 80 post directly you need to install authbind, for reference you can follow below links :-

Following works:

apt-get install authbind

First, set AUTHBIND=yes in /etc/default/tomcat7 file

sudo touch /etc/authbind/byport/80
sudo chmod 500 /etc/authbind/byport/80
sudo chown tomcat7 /etc/authbind/byport/80
