Multiple Tomcat Instances as a Service

Yesterday I posted how to set up Multiple instances of Tomcat running Railo. The whole setup turned out to be relatively painless.

Running the multiple instances as a service is a small improvement that can make life a little easier. A small adjustment to the service.bat file is all that is needed in the Windows environment, a startup script for the linux environment could also be made/modified in a similar way.

Service_Instance.bat

The first thing is to make a copy of service.bat and save it as service_instance.bat, once you have done that edit the service_instance.bat file and modify it.

Go down to line 63 and make the following changes

if "%1" == "" goto displayUsage
if "%2" == "" goto setServiceName
if "%3" == "" goto displayUsage
set SERVICE_NAME=%2
set PR_DISPLAYNAME=Railo 3.1 %2
set CATALINA_BASE=%3
:setServiceName
if %1 == install goto doInstall
if %1 == remove goto doRemove
if %1 == uninstall goto doRemove
echo Unknown parameter "%1"
:displayUsage
echo.
echo Usage: service.bat install/remove [service_name] [path_to_instance]
goto end

Save the file and then in a command prompt window you can do the following:

d:\tomcat6\bin>service_instance.bat install instance1 d:\tomcat6\server\instance1

When you check the windows Services you should see Railo 3.1 Instance1 as a new Service name. You should now be able to start/stop the service or set it to automatic.

Happy Coding...
