yes, just modify the server.xml on the 2nd instance so it runs on different ports.

RE: Multiple tomcat instances
From: Kelly, Steve [mailto:[EMAIL PROTECTED] Is it possible to run multiple instances of tomcat on the same server, for example to support production and test environments ? Yes. I run up to four on this machine - two (one 4.1, one 5.0) are running as I type this.

RE: Multiple tomcat instances
Another option which uses fewer resources but doesn't provide quite the same degree of isolation is to run two hosts in the same Catalina service. If your DNS maps www.mydomain.com and test.mydomain.com to the same IP address, they can share the same ports. Each one can have its own logs, Servlet mappings, and set of apps.

RE: Multiple tomcat instances
Steve, In the Host definition you specify an appBase for the applications directory (which will have a new ROOT under it), a Valve for the AccessLog, and whatever else you want to split off. The applications in the appBase directory will have their own WEB-INFO where you specify Servlet mappings, etc. The only restriction that I can think of is that the servlets in WEB-INF/web.xml must have different Servlet-names from those in conf/web.xml Fritz -Original Message- From: Kelly, Steve [mailto:[EMAIL PROTECTED] Sent: Friday, April 15, 2005 7:41 AM To: Tomcat Users List Subject: RE: Multiple tomcat instances Can you expand a bit more how this would work.

Re: Multiple Tomcat Instances with Linux
Jon, I run multiple tomcat services on a Linux box with Apache for various development and distributions. The way I went about it is to setup multiple Service configurations within the server.xml file. Each service has it own port for connectivity and its own worker for mod_jk. I create a virtual host entry in mod_jk.conf file which mounts the assigned worker which in turn points to the specific tomcat service. Here's the three files I touch to make it work and an example entry. My environment is Tomcat 4.1.29, mod_jk, and Apache 1.3.27. Hope this helps.

Re: Multiple Tomcat instances for virtual hosts
Your plan should work pretty well. I do something similar myself. The major difference is that I use one installation of Tomcat for all the sites. I have a script to start tomcat for each site, that points CATALINA_HOME to the shared Tomcat binaries, and CATALINA_BASE to the conf/, logs/, temp/, work/, and webapps/ directories for the site: file /home/site1/tomcat/catalina: #!/bin/sh CATALINA_BASE = /home/site1/tomcat CATALINA_HOME = /usr/share/tomcat4 (or whatever) CATALINA_OPTS = -server (maybe others) export CATALINA_BASE CATALINA_HOME CATALINA_OPTS $CATALINA_BASE/bin/catalina.sh $* I can do ./catalina start, ./catalina stop,etc to control each site. It works pretty well, especially if you're developing one site while others are in production. Two things to watch for: 1) You are correct that you have to use different ports for each server.xml file. I declared that site one could have ports between 8100-8199, site 2 between 8200-8299, etc. Each project can use whatever they want in their range. 2) Since these Tomcat instances listen on ports above 1024, they don't need to be started by the root user. If they did, I'd be very wary of putting the server.xml file (and other config files and scripts) where the user could modify them. Also, your system boot procedures need to take some steps to start them using the correct username. 3) I use Apache as a front end for all these Tomcat instances, using a proxy instead of JK or JK2. In each virtual host, there's something like this: ProxyPass /examples/ http://localhost:8181/examples/ ProxyPassReverse /examples/ http://localhost:8181/examples/ There are two nice things about this: Apache logs everything, making it easier to do usage reports. And, all the connections to Tomcat come from Apache and localhost, so I can block outside connections to all ports except the ones Apache listens to. However, it's still possible for user A to change his server.xml file to listen to a port that's being sent traffic for user B. For my purposes, that's not an issue; for others, it may be.

Re: Multiple Tomcat instances for virtual hosts
I really like the idea of setting up multiple instances of Tomcat per virtual site - i have 2 questions: 1) How does it affect memory usage, i.e. if we are on a server with X ammount of ram and there are 20 sites, does each site end up needing a minimum of ~21 MB RAM for tomcat so we have a basic need of 420MB ram being used just to keep tomcat up / site? 2) If one site gets busier then will it slow down the other sites more so than using mod_jk / mod_webapp? sai On Sat, 06 Sep 2003 21:05:38 -0400, Bob Langford wrote Your plan should work pretty well.

RE: Multiple Tomcat instances

It's possible to setup differenzt IP's on one maschine and use the same port on each of them) - What's the problem ? In my installation startup.sh etc. are readable and executable by anybody.

Now, to start each instance, each user telnets into the server and executes the command '/usr/bin/tomcat4 start'. The directories tomcat uses are all correct (it does use the correct CATALINA_BASE). _ The problem is this: Tomcat runs for each user if no other tomcat instance is running (I ensure that by running gtop on the server and killing instances run by other users). However, if one other instance of tomcat is running (by another user), we get the error message below. I have tried commenting out all the connectors except for non-SSL HTTP/1.1. I have turned them all on and generated keystore files for SSL. I have replaced the hostnames with the IP addresses. Nothing seems to work. I am at a complete loss at what to do. If anybody has ANY idea where to go from here, I am open to suggestions. _ error message is: Catalina.start: LifecycleException: Error creating server socket (java.net.BindException): java.net.BindException: Address already in use LifecycleException: Error creating server socket (java.net.BindException): java.net.BindException: Address already in use at org.apache.catalina.connector.warp.WarpConnector.initialize(WarpCo nnector.ja va:491) at org.apache.catalina.core.StandardService.initialize(StandardServic e.java:454 ) at org.apache.catalina.core.StandardServer.initialize(StandardServer. java:553) at org.apache.catalina.startup.Catalina.start(Catalina.java:780) at org.apache.catalina.startup.Catalina.execute(Catalina.java:681) at org.apache.catalina.startup.Catalina.process(Catalina.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorIm pl.java:39 ) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAc cessorImpl .java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:243) - Root Cause - java.net.BindException: Address already in use at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:321) at java.net.ServerSocket.bind(ServerSocket.java:308) at java.net.ServerSocket.bind(ServerSocket.java:266) at java.net.ServerSocket.init(ServerSocket.java:182) at java.net.ServerSocket.init(ServerSocket.java:138) at org.apache.catalina.net.DefaultServerSocketFactory.createSocket(De faultServe rSocketFactory.java:118) at org.apache.catalina.connector.warp.WarpConnector.initialize(WarpCo nnector.ja va:485) at org.apache.catalina.core.StandardService.initialize(StandardServic e.java
RE: multiple Tomcat-instances and a confused servlet...
In server.xml, ContextInterceptor className=...AutoSetup will automatically add subdirectories of TOMCAT_HOME/webapps as contexts, using the subdirectory name as the context name. Context declarations in server.xml can override the settings for the auto-added contexts. If you don't want a web application automatically served, move it outside of the TOMCAT_HOME/webapps or remove the interceptor so no contexts are automatically served.

RE: Multiple Tomcat Instances
Hello, You need a single mod_jk.conf and a single worker.properties. You need to write it yourself: you declare your two tomcats into workers.properties, and for getting your mod_jk.conf, you merge your 2 mod_jk.conf.auto, but when you make the mapping for the dynamic part of a webapp (servlets or jsps) you have to specify on which tomcat to sent the request. For example, if you have a foo webapp in a tomcat1, and a bar webapp in a tomcat2: in workers.properties, you need something like: worker.list=ajp_tomcat1,ajp_tomcat2 worker.ajp_tomcat1.port=8007 worker.ajp_tomcat1.host=localhost worker.ajp_tomcat1.type=ajp12 worker.ajp_tomcat2.port=8009 worker.ajp_tomcat2.host=localhost worker.ajp_tomcat2.type=ajp12 and in mod_jk.conf, something like: JkMount /foo/servlet/* ajp_tomcat1 JkMount /foo/*.jsp ajp_tomcat1 JkMount /bar/servlet/* ajp_tomcat2 JkMount /bar/*.jsp ajp_tomcat2 Xavier Marjou -Original Message- From: Abhijat Thakur [SMTP:[EMAIL PROTECTED]] Sent: Friday, September 07, 2001 7:16 PM To: [EMAIL PROTECTED] Subject: RE: Multiple Tomcat Instances I am using two tomcats server1.xml AJP on Port 8007 server2.xml AJP on port 8009 I am using Http via Apache.Every time i start tomcat with one of server.xml files i rename the mod_jk.conf-auto and the included the two static files in httpd.conf.

RE: Multiple Tomcat Instances
What you are trying to do isn't quite supported by Tomcat 3.2.x. The name of the auto-generated config file is not configurable, so the second Tomcat instance steps on the first's. I would recommend renaming the config file after starting each instance of Tomcat. Whenever a context is added or removed, repeat this process. Running multiple instances is better supported in Tomcat 3.3. The auto-generated file is written by a module (a.k.a interceptor) in the server.xml. Parameters may be specified, which include the name of the config file to write and where to write it. Your two server.xml files could specify different file names to avoid overwriting each other.

Re: Multiple Tomcat instances on one machine
This is not the case for me. I have verified which work directory is being used by removing everything in the work directory at both the top level and the instance level before starting Tomcat. After starting Tomcat, I noticed that the top level work directory is being used. I can get around that by setting the workDir attribute for the ContextManager in server.xml. But now I need to customize the other configuration files in conf for each instance. By the way, I am running Tomcat 3.2.1 on Solaris 7.
