Port 8080 already in use in eclipse

I am trying to run a Spring MVC demo file on Eclipse oxygen when I hit the button run as> run on server it shows the following error after a moment

Port 8080 required by Tomcat v8.5 Server at localhost is already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s)

Followed below steps and was able to solve the issue:

C:\Users\Sri Priya P Kulkarni>netstat -o -n -a | findstr 0.0:8080 TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 13196

C:\Users\Sri Priya P Kulkarni>taskkill /F /PID 13196 SUCCESS: The process with PID 13196 has been terminated.

My method is to run tomcat7w.exe to disable it. (Only Stopping it is not enough). And my Kaspersky (Anti virus) generate some new rules for eclipse and java.

Always Kill the process before deploying your war file in tomcat

ps -A|grep tomcat It will list all tomcat process. Note Down the PID and run

KILL <PID>

Cross check by ps -A|grep tomcat

Step 1: (open the CMD command)

  C:\Users\username>netstat -o -n -a | findstr 0.0:8080

  TCP 0.0.0.0:3000 0.0.0.0:0 LISTENING 3116

  Now , we can see that LISTENING port is 3116 for 8080 ,

  We need to kill 3116 now

Step 2:-

 C:\Users\username>taskkill /F /PID 3116

 Step 3: Go to Eclipse and start Server , it will run

OR 

 you can change port number in folder  servers>Tomcat>server.xml

You can just change the default port of your Tomcat server if the problem persists.

A process is already listening on port 8080 and you can't have more than one process listening on the same port.

You have two options :

  1. Kill the existing process if it's not usefull netstat -tulpn | grep :8080

  2. Change you application port. In your application.properties and file add this line server.port=8081

in your apache conf folder, open the httpd file and look for 8080 port. Change 8080 to any port you like. I believe you will find 8080 on two places
