Setup Advice Needed: dev vs. test vs. production
I have some web services running on tomcat and I am trying to figure out the best way to have 1 tomcat instance running all 3 environments. So the tomcat would run dev, test, and production on one tomcat instance. I don't want to install 3 instances of tomcat on the customers machine for running the different environments. I guess the way I would like it to work is to have the web services have the same name regardless of the environment. The easy way to think about it is to have each environment running on a different port. Is this possible? Or would it be easier to have a virtual host? For now I just need to be pointed in the correct direction on what is the best way to handle this situation with tomcat. If you do have a suggestion and know how to set it up then please pass it along. Thanks, Susan === Susan G.

RE: Setup Advice Needed: dev vs. test vs. production
I hear you. But in our environment it just isn't feasible to install three different tomcats on the customer's system. So I was trying to come up with a way to do this without having to rename a bunch of stuff. If it was running on a different virtual host for each environment or different ports. Can Tomcat be setup so 3 VM instances are ran under one tomcat installation? With the constraint that only one tomcat can be installed on the system what is the best way to run 3 separate environments?

With the constraint that only one tomcat can be installed on the system what is the best way to run 3 separate environments? The answer is don't. If you cannot have more than 1 tomcat in the enterprise, then you should schedule downtime for the production system, to do your testing. Undeploy the prod.war and deploy the test.war or dev.war. When done, undeploy then deploy the prod.war.

RE: Setup Advice Needed: dev vs. test vs. production
Susan, Are you wanting to only perform one (1) install of the Tomcat software? What is the customer environment (O/S, etc.) that is imposing this requirement? I am going to guess that it is possibly Windows, and not Linux. But whichever, what you probably want is multiple instances of Tomcat running off the same install. This has been discussed many times on this list, and I think is documented in the Tomcat docs. Please conduct a search. Also, if it is Windows, it's pretty easy to set up multiple services using the service installer, so each can be controlled separately. For ease of use by your users, I would suggest 3 different IPs/DNS names assigned to the physical server with each Tomcat instance being configured for one of them.

Chuck's reply about reading RINNIGN.txt is what I was talking about here. He also makes several good points on why separate installs is desirable. -Original Message- From: Jeffrey Janner [mailto:jeffrey.jan...@polydyne.com] Sent: Friday, January 21, 2011 1:15 PM To: 'Tomcat Users List'; 'cong...@yoeric.com' Subject: RE: Setup Advice Needed: dev vs. test vs. production Susan, Are you wanting to only perform one (1) install of the Tomcat software?

RE: Setup Advice Needed: dev vs. test vs. production
You are preaching to the choir here about the multiple installs. But I can't. This is running on an AS400. And the clients are very particular on what you can install. So I am stuck. FYI: The dev, test, and production is for my software not Tomcat. So I have 3 or more versions of the software that I have to support. I want to have 1 tomcat installation will all of the versions on it at my customer site. Actual development happens on my laptop but sometimes I have versions that the customer has to play with and give feedback on that aren't ready for testing. This I would install under dev, then others that are actually in the testing phase and then finally production. On my laptop I have multiple tomcat installations but I don't have that luxury on the customer's as400. So my thought process is I will have to change my software that communicates with the web services so that it calls different web services depending on dev, test, or production. However I don't want to have to do this. It would be better if I could just change the port. I don't know if a virtual host would give me anything or not.

You don't have to install anything else. Read RUNNING.txt, specifically the Advanced section. It will explain everything. On my laptop I have multiple tomcat installations but I don't have that luxury on the customer's as400. You should adopt the procedure above for your laptop, too: no need for multiple Tomcat installations unless you actually want different TC versions. So my thought process is I will have to change my software that communicates with the web services so that it calls different web services depending on dev, test, or production.

It would be better if I could just change the port. I don't know if a virtual host would give me anything or not. If you are changing the port, virtual hosting doesn't add anything. If you are doing virtual hosting, changing the port doesn't add anything. If you run multiple TC instances, it's easier to configure and deploy (in my opinion) and you get the added benefit that your dev service can't take down your production service. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk056yMACgkQ9CaO5/Lv0PDYtQCfUKI0Rv+r4IjbuauTwKXeHitS MAwAoKhK0q1AyCRn+7Nk2cpSjnYzSR2Y =WuWx -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
