shutting down tomcat on port 8080

Question

I have problem in shutting down tomcat server. When I type localhost://8080, it keeps on showing me tomcat homepage. I restarted the system also but did not help. I have already tried following commands and it did not show any process which might be running on port 8080 (Following commands did not output anything.)

netstat -anp|grep :8080[[:blank:]]

fuser -n tcp 8080

lsof -w -n -i tcp:8080

netstat | grep 8080

I also tried netstat -tulpn which shows following. I dont see any process running on port 8080 there.

Could someone please tell me how to free port 8080. I tried to run ./shutdown of tomcat but it shoed java.net.ConnectException: Connection refused

I guess it is because of already running instant on port8080.

Thanks.

Answer 1

It worked for me,

1. In terminal, run:

   fuser -n tcp 8080
   

   Now we got some output like this:

   8080/tcp:            15008
   

   Here 15008 is where our apache is running.

2. Kill that using:

   kill -9 15008
   

3. Done.

Answer 2

If you installed tomcat from Software Center (or via apt-get command line), then it should be running from the standard ubuntu installation directory. Starting and stopping Tomcat should be as easy as

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop

Maybe 5.5 needs to be replaced by the version you are using.

If you just downloaded tomcat and are running from your custom unzipped directory, the startup and shutdown scripts provided by Apache should work. Assuming your tomcat is in $TOMCAT_HOME:

$TOMCAT_HOME/bin/startup.sh
$TOMCAT_HOME/bin/shutdown.sh

If all fails, you can always manually kill all java processes

killall java

or, if something is REALLY stuck

killall -9 java

These last ones will kill ALL java processes currently running.

Answer 3

ps -ef |grep 'catalina'

then take that pid

kill -9 $pid

alternatively if you want to free 8080 port

Change your tomcat port to other than 8080

vi $CATALINA_HOME/conf/server.xml

search for the following section and then change port number to any thing of you choice.

<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" />

save the changes and restart the tomcat. Now your 8080 port will be free as tomcat will be running to alternative port you changed.

Try this command may be help you

sudo kill `sudo lsof -t -i:8080`
