Tomcat 7 doesn't shut down, process keeps running?

Question

I started tomcat 7 using,

cd /opt/tomcat7/bin    
$/opt/tomcat7/bin ./startup.sh

It shows process running

root     23206  130  3.4 1323956 572880 pts/2  Sl   07:58   1:05 /usr/bin/java -Djava.util.logging.config.file=/opt/tomcat7/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Dspring.profiles.active=mongo1,maxListenersAllowed -DST_SERVER=mongo1 -Djava.endorsed.dirs=/opt/tomcat7/endorsed -classpath /opt/tomcat7/bin/bootstrap.jar:/opt/tomcat7/bin/tomcat-juli.jar -Dcatalina.base=/opt/tomcat7 -Dcatalina.home=/opt/tomcat7 -Djava.io.tmpdir=/opt/tomcat7/temp org.apache.catalina.startup.Bootstrap start

If I shutdown it using

$/opt/tomcat7/bin ./shutdown.sh

It gives this message

Using CATALINA_BASE:   /opt/tomcat7
Using CATALINA_HOME:   /opt/tomcat7
Using CATALINA_TMPDIR: /opt/tomcat7/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /opt/tomcat7/bin/bootstrap.jar:/opt/tomcat7/bin/tomcat-juli.jar

but if I check the above process, it still shows it running. Tomcat doesn't shut down. I tried it using root user as well but still no success.

Manully I can kill the process but I want to create deploy script so want to do it using shutdown.sh and startup.sh

Same happens if I try using

/opt/tomcat7/bin/catalina.sh start
/opt/tomcat7/bin/catalina.sh stop

Answer 1

You can force the shutdown by PID.

Edit

..tomcat/bin/catalina.sh

and set the

CATALINA_PID=path

variable to a local path.

CATALINA_PID

(Optional) Path of the file which should contains the pid of the catalina startup java process, when start (fork) is used

then you can shutdown Tomcat with -force flag

../tomcat/bin/shutdown.sh -force

If the script can not stop Tomcat normally will use a kill to stop the process by PID.

Update:

According to Joshua Taylor comment, the recommended way to store additional variables for running tomcat is the setenv.* script.

Take a look at (3.4) Using the "setenv" script (optional, recommended) section in the tomcat running docs

https://tomcat.apache.org/tomcat-7.0-doc/RUNNING.txt

Answer 2

I once had the misfortune of a page running infinite redirect loops due to a faulty authentication mechanism.

It eventually slowed down the entire server, but also made it impossible for me to shut it down gracefully. In the end I had to employ brute force like vzamanillo describes.

The point being that something fishy might be running within your server's processes that won't finish properly.
