Tomcat startup, 8080 address already in use

100,124

Solution 1

I also had the same issue. Tried all the options suggested in this thread. But didnt help. Then just did ran:

ps -awwef | grep tomcat

and found some stale process running. I killed it using (-15 instead of -9)

sudo kill -15 <tomcat pid from previous command>

And woot! it worked. Restarted tomcat without any issue.

Solution 2

NEVER kill a process with signal -9, because this type of killing process leaves its resources present in the system, which can only be removed after a server reboot. only use kill -9 only in extreme emergency. better to use kill -15, as it might take some time to cleanup resources, but you would always get proper flushing of that whole set of resources, that the process is consuming. so most probably, the tomcat is not working as it has left some of the resources left in the memory. So, either perform a reboot or try to find following:

through lsof command and grep it with tomcat. it will show you anything that has tomcat associated with it

lsof | grep tomcat

search of any pid lock file on filesystem, left by tomcat.
Also try to issue:

lsof -i TCP | grep 8080

Solution 3

The port number is configured in $TOMCAT_HOME/conf/server.xml

If port 8080 is in use, change it in the server.xml file. Mine looks like this in server.xml

<Connector port="8085" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" />

Solution 4

Just running a lsof may be not enough. I suggest this command:

sudo lsof -i :8080

And then you can kill whatever process is holding the port (most probably another instance of tomcat).

Solution 5

Just for the record: I got this error (as a newbie) because I started Apache before starting Tomcat.

If I stopped Apache, then started Tomcat and then started Apache, the errors disappeared.

The setup is:

Amazon EC2
Tomcat (with secure forwarding to 8443)
Apache 2.2

I run the shutdown.sh, and I get no errors.

BUT when I try to runt the startup.sh I get this error:

Any thoughts or pointers?

I tried rebooting, the problem did not get solved. I read about this problem, it's like you stated - resources present in the memory. But how do they survive a rebooT?! :S
marko over 12 years

Tried changing it to 8181 8383...no effect! This seems like a work around, what I'm looking to do is run on 8080 no matter what. The problem isn't even solved by a reboot!

try to run ps -aux | grep java, and look for any processes of java running at startup.

thanks for the suggestions, I've tried ps -efl | grep java (and other similar combination) noting worked. Eventually I terminated my amazon instance and created a new one...

Ran ps -aux | grep java. Killed the two instances of Tomcat identified using kill -15. It worked. Thank you!
