How to Check if Tomcat is already running
Apache Tomcat ( or merely Tomcat ) is an open reservoir web server and servlet container developed by the Apache Software Foundation ( ASF ). tom implements the Java Servlet and the JavaServer Pages ( JSP ) specifications from Oracle Corporation, and provides a “ pure Java ” HTTP web server environment for Java code to run.

If you have any of below questions then you are at right place :

  • Several ports (8080, 8081, 8082) required by Tomcat Server at localhost are already in use
  • Tomcat Server Error – Port 8080 already in use
  • port 8080 required is in use
  • port 8080 already in use eclipse
  • how to stop port 8080 in windows

I ’ ve apparatus tomcat as Windows Service. Running Tomcat as a Windows Service provides a number of benefits that are necessity when moving from a development set-up to a production environment .

Benefit-1) Setup reliable automatic startup on boot

  • Essential in an environment where you may want to remotely reboot a Java System after maintenance without worrying about whether your server will come back online.

Benefit-2) Setup Tomcat server startup without active user login

  • In a data center, it is not reasonable to expect an active login from the system just to run Tomcat. In fact, Tomcat is often run on blade servers that may not even have an active monitor connected to them. Windows Services are owned by the System, and can be started without an active user.

Benefit-3) Better Security

start/stop my //XX// ServiceName recently I wanted tomy Tomcat Server via command credit line as wanted to create flying shall script to do it. official documentation provided below commands in the phase of

Available command line options are:

  • //TS// Run the service as console application This is the default operation. It is called if the no option is provided. The ServiceName is the name of the executable without exe suffix, meaning Tomcat6
  • //RS// Run the service Called only from ServiceManager
  • //SS// Stop the service
  • //US// Update service parameters
  • //IS// Install service
  • //DS// Delete service Stops the service if running

But rather doing it this way I found below commands very utilitarian and simple .

1) Windows (if Tomcat is setup as Windows Service)

  • To Start server: /bin>Tomcat8.exe start
  • To Stop server: /bin>Tomcat8.exe stop

2) Windows (if you have downloaded binaries as .zip)

  • To Start server: /bin>catalina.bat start
  • To Stop server: /bin>catalina.bat stop

3) Mac/Linux/Unix (if you have downloaded binaries as .zip)

  • To Start server: /bin>./catalina.sh start
  • To Stop server: /bin>./catalina.sh stop

Below are all catalina.sh control parameters :
