I'm using Apache Tomcat 8.0.41 on Ubuntu 16.04 LTS. When
I "kill -9" the tomcat process, it keeps restarting by

so I don't know what is causing it to restart after "kill
-9". Please consider the following proof:

What do I need to do to make tomcat stop restarting
itself?
How do you *start* Tomcat?
-chris
I use "catalina.sh start". Here is my "setenv.sh" contents:
CATALINA_HOME="/opt/tomcat"
JAVA_HOME="/usr/lib/jvm/java-8-oracle"
CATALINA_PID="/tmp/catalina.pid" JAVA_OPTS="$JAVA_OPTS
-Xmx1g -Xms1g -server"
Hmm. I was thinking that maybe you were using systemd or something
that actually watches services and auto-restarts them. That
appears not to be the case.
What is the parent process of the JVM?

I'm not sure what you mean by the "parent process of the
JVM"...when I do "ps -ef | grep 'java'" only 1 process comes up and
that's the process I'm running "kill -9" on...
When you run "ps -ef" one of the fields you get is the PPID ("parent
process id"). Find out what THAT process is, and you might find the
answer to your question.

The PPID of my tomcat process is 1 which corresponds to "/sbin/init
splash". Just restarted my system and tomcat started up automatically.
Where do I disable the automatic starting of tomcat?
