Multiple development sites using different ports
I'd like to configure Tomcat so that I can run multiple dev websites as root
relative and distinguish them via port numbers. In order words, I'd like to
run http://localhost:8080/index.jsp and have that be a different site (using
a different directory) than http://localhost:9800/index.jsp
The reason this matters to me is because I like running my sites as
root-relative. That way I can reference images, files, etc as, for example,
/images/logo.png rather than having to traverse the directory structure via
"../". This makes the site much more portable and accurately reflects how
the site will run in production anyway (where most sites run as root).
So can anyone give me a quick primer on how to configure Tomcat to use
multiple ports for root-relative development? I have spent several hours
researching this with no luck.
I am currently running Tomcat 6.0
Thanks.

Re: Multiple development sites using different ports
Posted by Yves Glodt <yg...@mind.lu>.
Hello,
yesterday I set up exactly what you need
You need to set up 2 "services", and inside define your hosts and connectors.
So here my server.xml:
<Server port="8005" shutdown="SHUTDOWN" debug="0">
<Service name="inst1">
<Connector port="8180" minProcessors="5" maxProcessors="75"
useBodyEncodingForURI="true" enableLookups="true" redirectPort="8443"
acceptCount="100" debug="0" connectionTimeout="20000"
useURIValidationHack="false" disableUploadTimeout="true" />
<Connector port="8009" enableLookups="false" redirectPort="8443"
protocol="AJP/1.3" />
<Engine name="Standalone" defaultHost="localhost" debug="0">
<Host name="localhost" debug="0" appBase="webapps" unpackWARs="true"
autoDeploy="true">
<Logger className="org.apache.catalina.logger.FileLogger"
directory="logs" prefix="www.example.com." suffix=".txt"
timestamp="true" />
<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" />
</Host>
</Engine>
</Service>
<Service name="inst2">
<Connector port="8181" minProcessors="5" maxProcessors="75"
useBodyEncodingForURI="true" enableLookups="true" redirectPort="8443"
acceptCount="100" debug="0" connectionTimeout="20000"
useURIValidationHack="false" disableUploadTimeout="true" />
<Connector port="8010" enableLookups="false" redirectPort="8443"
protocol="AJP/1.3" />
<Engine name="Standalone" defaultHost="localhost2" debug="0">
<Host name="localhost2" debug="0" appBase="/home/tomcat/yourapp"
unpackWARs="true" autoDeploy="true">
<Logger className="org.apache.catalina.logger.FileLogger"
directory="/home/tomcat/yourapp/logs" prefix="www.example.com2." suffix=".txt"
timestamp="true" />
<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" />
</Host>
</Engine>
</Service>
</Server>
This makes you 2 tomcats, one on loaclhost:8180 and the other on
loaclhost:8181, with different folders in the filesystem where the webapps are
deployed, one in /var/lib/tomcat5.5/webapps, and the other in
/home/tomcat/yourapp
I use tomcat 5.5, but I guess this will work on 6.0 as well.
Regards,
Yves

You bet. First, ping devlocal1 and devlocal2 to make sure both names
are being resolved.
Then go comment out one of your Service elements and try to access
the other. Tail -f the catalina.out log file, making sure your Connectors
are starting properly.
If that works, reverse it and try the other Service.
When they're confirmed to work independently, try together.
However, I'd give the Engine elements different names, and I'd get rid
of the Cluster (unnecessary) and Logger (invalid) elements first...

Ha, that's embarrassing. I've been substituting real names for fake ones for
the sake of this discussion and got my wires crossed in my reply.
In any event, I have tried what you suggested re: the hosts file and still
no dice. There is a slight difference this time, though. Rather than
getting a "can't establish a connection" message, I get a blank page. Is
that progress? 8-)
Also, no log files are being created.

which doesn't match either of the above :-)
In any case, you need to set up /etc/hosts like:
127.0.0.1 localhost devlocal1 devlocal2
# all host aliases for a given address on same line
::1 localhost

RE: Multiple development sites using different ports
Posted by dylanmac <dy...@gmail.com>.
So here's what I entered in my server.xml file based on various pieces of
advice:
<Service name="instance1">
<Connector port="9091" protocol="HTTP/1.1" connectionTimeout="20000"
redirectPort="8443" />
<Connector port="8010" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Standalone" defaultHost="devlocal1" debug="0">
<Host name="devlocal1" debug="0" appBase="webapps/devlocal1"
unpackWARs="true" autoDeploy="true">
<Logger className="org.apache.catalina.logger.FileLogger"
directory="logs" prefix="devlocal1" suffix=".txt" timestamp="true" />
<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" />
</Host>
</Engine>
</Service>
<Service name="instance2">
<Connector port="9092" protocol="HTTP/1.1" connectionTimeout="20000"
redirectPort="8443" />
<Connector port="8011" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Standalone" defaultHost="devlocal2" debug="0">
<Host name="devlocal2" debug="0" appBase="webapps/devlocal2"
unpackWARs="true" autoDeploy="true">
<Logger className="org.apache.catalina.logger.FileLogger"
directory="logs" prefix="devlocal2" suffix=".txt" timestamp="true" />
<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" />
</Host>
</Engine>
</Service>
and here's what's in my hosts file:
127.0.0.1 localhost
::1 localhost
127.0.0.1 devlocal1
127.0.0.1 devlocal2
When I try to hit either http://devlocal1/ or http://localhost:9091/ this is
what I get in my browser (and yes, Tomcat was restarted)
Failed to Connect
Firefox can't establish a connection to the server at revfoodslocal:9091.

What did you try and what didn't work? Be specific.
Did you read the doc:

Only if you're going to expose your web sites to an uncontrolled set of clients (e.g., the Internet). Otherwise, as Hassan noted, simply update the /etc/hosts file on each client computer to include all the host names you want, all targeting the same IP address. (For Windows clients, it's in C:\WINDOWS\system32\drivers\etc\hosts.)

If this is only for your own use -- as I surmise from your examples of
http://localhost:nnnn/ -- you don't need DNS. Just put the names in
your /etc/hosts file (or equivalent).
I always do multiple dev sites this way. It's dead simple.

I looked at name-based virtual hosts and couldn't get it working. Moreover
all of the documentation says I need to configure the DNS properly for
name-based virtual hosting to work. Where do I do that?
Thanks.

It's easier to do name-based virtual hosts.
But if extra work appeals to you :-) create multiple Service elements,
each with appropriate Connector and Host entries.
FWIW!

Yeah, it takes some getting used to. There are many port numbers to
juggle and stuff like that. Once you get it working, it should all make
sense.

Right. Since Java makes it so easy to do context-relative paths, there's
basically no excuse for not doing it.

JSTL (which is stndard these days) has the <c:url> tag which should
automatically make URLs that look like root-relative (e.g. those that
start with a /) into context-relative URLs without you having to do
anything at all. You also get url-rewriting for session tracking when
the client doesn't support cookies. Bonus!

You may not have bin/catalina.sh (or .bat) in your distro (I've heard
that certain windows binary installs are missing these files, since the
service is the expected usage), so you probably haven't seen this
portion of it:
~ ...
~ -Dcatalina.base="$CATALINA_BASE" \
~ -Dcatalina.home="$CATALINA_HOME" \
~ ...
You should just be able to set catalina.base and catalina.home (JVM
properties) from the service configurator thing (tomcatw.exe maybe? I
don't do win32, sorry). Anyhow, just use the syntax shown above for
adding system properties or command-line arguments -- however the GUI
presents itself for configuring the service. Obviously, replace
$CATALINA_BASE with the actual path, etc. _HOME points to the actual
Tomcat install, while _BASE points to the separate instance you want to run.
You'll have to check back with someone else to figure out how to run
multiple win32 services like this. I've run out of win32 experience, here.
Good luck,

You would be better off using paths that are relative to the context
root. There are many tools that will do this form you in JSPs or

Check out the RUNNING.txt file that ships with Tomcat. Read the
"Advanced Configuration - Multiple Tomcat Instances" section; it should
help a lot.
The only thing you have to remember to do is to set the ports for each
instance's <Connector> elements and make sure you don't get confused.
I have this exact same setup in dev, test, demo, and prod (with the
addition of Apache httpd and mod_jk, too), so I should be able to answer
any questions you have.
