Re: HOW TO install/setup 2 instances of tomcat on same server
that is on windows... I am working on linux via ssh! I dont have anything installed on my PC... David Smith-2 wrote: If you installed tomcat using the .exe installer, go get the .zip download and grab the service.bat file from it's bin directory. If you installed .zip version of tomcat, you should have a file in the bin directory named service.bat. Service.bat can help you create new tomcat services in the Windows environment, each with their own name for start/stop/restart. If you want to get custom with the setup, just take a look at how the bat file creates a new service and then roll your own from the command line. --David edponce wrote: DAvid I am on windows, but i connect to the server via ssh so all the commands are just like in Linux. I've tried tomcat5 start, but i think that just works for the original tomcat, also, how can i check that when i start the 2nd instsance of tomcat it start with no errors. Thank you Eduardo David Smith-2 wrote: Ok ... forgive me if this was posted already, but what OS do you have and how are you starting the production instance?

I've duplicated my tomcat folder and renamed it and ive changed the 2 connector and the server shut down port. But i dunno how to start the duplicate instance. how can i do that! Thank you, Eduardo David Smith-2 wrote: Can any one please guide me on the correct direction so that i don't mess up anything! I've never worked with Tomcat that is why i have no idea on how to do it. Yes. Just open the server.xml file in tomcat's conf directory and look for the Connector ... / elements that aren't wrapped in xml comments ( !-- -- ). In those you will see port=8009 or whatever. Just make sure they are all unique in both server.xmls. Also change the port number in the Server ... element so it doesn't conflict with the other. As an aside, I would recommend putting together a new server.xml, removing all the xml comments to make an easier to read server.xml. Keep the original around for documentation/reference as server.original.xml or whatever you like. You do not necessarily need two separate instances of Tomcat. Under Tomcat, each application can be started and stopped (and even a new version reloaded) without stopping the Tomcat server. Technically yes, but if you restart the app enough times you will run out of memory and need to restart the service. The max webapp restart count is dependent on how big the webapp is as well as how much extra memory tomcat has. It's better to occasionally restart a dev instance of tomcat than bounce a production instance when it stops responding. --David André Warnier wrote: André Warnier wrote: edponce wrote: I know this question has been asked a lot but I've read different solutions depending on the needs of the problem.

Can any one please guide me on the correct direction so that i don't mess up anything! I've never worked with Tomcat that is why i have no idea on how to do it. Ok, serious now. This is at the same time some information for you, the Original Poster (OP), and a question for the others on this list more Tomcat-qualified than I am. But we've got to start somewhere... To the OP (and the others to contradict me if I'm wrong) : You do not necessarily need two separate instances of Tomcat. Under Tomcat, each application can be started and stopped (and even a new version reloaded) without stopping the Tomcat server. You would just need to name your applications differently. (like http://host.mycompany.com/real-app; and http://host.mycompany.com/test-app;). There also exists the possibility to run one Tomcat with different Virtual Hosts, on the same port 80. Each one of these virtual hosts would have a different DNS name (like realserver.mycompany.com and testserver.mycompany.com) and could have a different directory where the applications reside, but the application itself would be named the same way. I am mentioning the above two possibilities because, you knowing not much about Tomcat to start witj, either one of the above is probably easier

Hi edponce
so if i understood everything i just need to duplicate the tomcat

Yes, you just need to duplicate it. You can call the duplicate folder
whatever you like.
Then On the duplicated tomcat
directory, you need to edit the server.xml file so that the second
server.xml as unique ports for the shutdown port, the interface port
(eg 8080 could become 8081 etc) and how can i check if i've done this
correctly? that both instances are running?
Yes. Check your logs during startup and shutdown also for any
warnings or port binding issues.
Thanks for your help...
You're welcome.

environments as each should have their own log directories.

Re: HOW TO install/setup 2 instances of tomcat on same server
DAvid I am on windows, but i connect to the server via ssh so all the commands are just like in Linux. I've tried tomcat5 start, but i think that just works for the original tomcat, also, how can i check that when i start the 2nd instsance of tomcat it start with no errors. Thank you Eduardo David Smith-2 wrote: Ok ... forgive me if this was posted already, but what OS do you have and how are you starting the production instance?

Just make sure they are all unique in both server.xmls. Also change the port number in the Server ... element so it doesn't conflict with the other. As an aside, I would recommend putting together a new server.xml, removing all the xml comments to make an easier to read server.xml. Keep the original around for documentation/reference as server.original.xml or whatever you like. You do not necessarily need two separate instances of Tomcat. Under Tomcat, each application can be started and stopped (and even a new version reloaded) without stopping the Tomcat server. Technically yes, but if you restart the app enough times you will run out of memory and need to restart the service. The max webapp restart count is dependent on how big the webapp is as well as how much extra memory tomcat has. It's better to occasionally restart a dev instance of tomcat than bounce a production instance when it stops responding. --David André Warnier wrote: André Warnier wrote: edponce wrote: I know this question has been asked a lot but I've read different solutions depending on the needs of the problem.

(like http://host.mycompany.com/real-app; and http://host.mycompany.com/test-app;). There also exists the possibility to run one Tomcat with different Virtual Hosts, on the same port 80. Each one of these virtual hosts would have a different DNS name (like realserver.mycompany.com and testserver.mycompany.com) and could have a different directory where the applications reside, but the application itself would be named the same way. I am mentioning the above two possibilities because, you knowing not much about Tomcat to start witj, either one of the above is probably easier to set up than two separate Tomcat instances. The difference between the above solutions and two really separate Tomcat instances would be if the test application could really crash the whole server, in which case you may not like one of the above solutions.

Re: HOW TO install/setup 2 instances of tomcat on same server

Whilst a little cumbersome, and inefficient from a resource usage standpoint, when you're learning, being able to restart tomcat as you shop and change the server.xml file etc can be useful, without fear of breaking the production service. It can also be useful for evaluating a new version before you unleash it to production. edponce: If you want to run two instances, the easiest way, to my mind, is to duplicate the tomcat directory. On the duplicated tomcat directory, you need to edit the server.xml file so that the second server.xml as unique ports for the shutdown port, the interface port (eg 8080 could become 8081 etc). Once you have made these changes, you should be able to start each of them up by running their respective startup scripts. You could achieve the same using links and a few other sharing techniques, but for simplicity's sake, I think this approach to two instances using duplicated directories is the most robust.

HOW TO install/setup 2 instances of tomcat on same server
I know this question has been asked a lot but I've read different solutions depending on the needs of the problem. I need to have 2 instances of tomcat on the same server for the same application. One would be for production and the other for development (which can be start and stopped whenever without affecting the production one). From my understanding i need to have each instance on different ports and modifying some other files but what I am missing is the technical things. Can any one please guide me on the correct direction so that i don't mess up anything! I've never worked with Tomcat that is why i have no idea on how to do it.
