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

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? Windows systems starting the production tomcat as a service is different than Linux/Unix systems starting tomcat with jsvc or a service script. --David edponce wrote: David, Thanks for replying. 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.

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 to

You need to add the execute privilege to your tomcat5-test script. Take

I suspect there are soft links in /etc/tomcat5 (or /etc/tomcat5 itself
is a softlink) to /usr/share/tomcat5. In that case, duplicate both.
Disk space is generally cheap and tomcat doesn't take that much room.
That would also bolster separation of the dev and production

You need to add the execute privilege to your tomcat5-test script. Take
a look at the man page for chmod.

I suspect there are soft links in /etc/tomcat5 (or /etc/tomcat5 itself
is a softlink) to /usr/share/tomcat5. In that case, duplicate both.
Disk space is generally cheap and tomcat doesn't take that much room.
That would also bolster separation of the dev and production
environments as each should have their own log directories.

DAvid I am on windows, but i connect to the server via ssh so all the commands are just like in Linux.

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

Re: HOW TO install/setup 2 instances of tomcat on same server
Tom,
ive created this start script...what i did is modified the previous path of
the original tomcat instance to the new one... wich was /etc/tomcat5 (where

Comments anyone ? When I was new to tomcat (arguably when compared with some members of this list, I could still be considered new), I found it conceptually easier to work with two instances, as you don't need to switch context names etc when you want to deploy live. 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.

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.

Why? Because, however good Tomcat is, webapp.s are notorious for leaking (and occasionally gushing) Tomcat's resources as they stop and start. Particularly with software under active development, there is the real possibility that app A will run Tomcat out of some vital memory pool and precipitate the crash of app B, though B be coded ever so carefully. Here our production Tomcats run pretty well. The development Tomcat can lock up several times a day, spinning at 100% CPU and unable to execute a controlled shutdown, as we update a developing app. a mere dozen times.

For Java webapp newbies, it's important to understand terminology and topography. Let's start with topography and move forward from there. You can deploy Tomcat either standalone (where Tomcat directly receives HTTP requests) or fronted with another web server like Apache httpd (which is a very popular setup). Your strategy depends a lot on which setup you'd like. You can also deploy your applications into, say, /myApp and /myApp-dev. If you have a preference, please let us know that before we do on. Explaining everything start to finish is lengthy and my fingers will get tired. So, let us know is you will be running Tomcat standalone or behind a web server, and then how you intend (or want) to deploy your webapps.

This is a list for Tomcat Users only (hence the name), and obviously you are not one of them, so go away ! Just kidding. Can you maybe give a bit more details, such as what system you are running this on, and the version of Tomcat if you know ? That would help, a bit. But it is probably not going to be easy, if you really have no idea of Tomcat to start with. Did you ever work with another Java servlet engine, or another HTTP server ? - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

To the OP : at least until Tomcat version 5.5, there is an integrated web-accessible Manager application, through which you can start and stop any application, and upload a new version and restart it. All this through a web form, and without restarting Tomcat. Comments anyone ? No matter which possibilities exist to set up multiple Tomcat instances on a single machine, I would *never* use a production server for development. If I was in the OP's shoes, I'd rethink this requirement (if it indeed is one). Me too. To the OP : it would really be more secure and stable to use two different servers, on which you could install two exactly identical Tomcat's. A test Tomcat does not necessarily need a big server, and your average clunky PC running Linux would probably do fine. (It does need some RAM though). That would be a lot easier to install, because you could have on each just a Tomcat out-of-the-box. (Also, whether you run Tomcat under Linux or Windows, from a pure-Java application point of view it is much the same.) Regards mks [1] Of course, one can create multiple Tomcat instances from a single binary by using multiple different CATALINA_BASEs. But that might be unnecessary complex in this case. Now, edponce, after reading the above and thinking about it, where do you incline ? And please, tell us some more about your exact environment if you can. Like, what is the server, what is the Tomcat version, where do you get it from, how do you install it, etc.. That would help us a lot to narrow down the possibilities. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Comments anyone ? When I was new to tomcat (arguably when compared with some members of this list, I could still be considered new), I found it conceptually easier to work with two instances, as you don't need to switch context names etc when you want to deploy live. 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. Tom
