Tomcat Server ports in use...what to do now

Question

I found the message telling me that the ports required by Tomcat are already in use.

netstat -an|grep 8080
tcp6       0      0 :::8080                 :::*                    LISTEN     
netstat -an|grep 8005
tcp6       0      0 127.0.0.1:8005          :::*                    LISTEN 

So,I created the file tcp6.js using Node.js and bound it to 9000:

 var net=require('net');
 var chat=net.createServer();
 chat.on('connection',function(client){
    client.write('Die');
    client.end();
 });

 chat.listen(9000);

I logged out and logged back in. But the netstat still shows tcp6 bound to 8080 and 8005. These are the results of

ps aux | grep tomcat

Answer 1

Go to tomcat home -> conf

There is a file called server.xml, in that search for 8080 and replace it with 8180 and restart the tomcat.
