I am working on linux server.

I want to know whether there exists a PID for each tomcat service running on any server.

If there exists a PID for a particular tomcat service, then can we find the service name corresponding to that PID?

Can we list all the tomcat services running on the server?

ps -ef |grep tomcat

sun 5144 1 0 10:21 pts/1 00:00:06 /Java/jdk/bin/java
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/java/tomcat/common/endorsed -classpath :/java/tomcat/bin/bootstrap.jar:/java/tomcat/bin/commons-logging-api.jar
-Dcatalina.base=/java/tomcat -Dcatalina.home=/java/tomcat -Djava.io.tmpdir=/java/tomcat/temp org.apache.catalina.startup.Bootstrap start

PID=5144

  • Thanks for your efforts. Actually when I am executing this command: ps -ef | grep tomcat. It is not showing anything. But there are some services in which instead of Dcatalina it is showing Dwapper and Djavax. Can you please tell me what is that? And how to find out those services from command line? – Aditya Jun 29 '17 at 12:15

You can use netstat to capture the PID. But this will depend on whether or not the service is actually running on the server. netstat would capture the port it is binding to as well as the PID and program name. Granted that you have Tomocat running on port 80, you can try the following:

netstat -tulnp | grep '80'
