Secondary instance of Tomcat on single server does not process requests
Hi all,
My secondary instance of Tomcat 6 does not process requests -- it simply
times out for everything. The only log is catalina.out and there are not
errors in it. Anyone know what could be wrong? I'm using Tomcat 6, Java
1.6.0_20, on Centos 5.5 Final.
I've set the secondary instance to use port 8081 for http and 8010 for AJP,
both have redirect ports of 8444.
Below is the directory structure of the secondary instance:
/data/tomcat2
|-- bin
|-- setenv.sh
|-- catalina.sh
|-- conf
|-- server.xml
|-- web.xml
|-- logs
|-- temp
|-- webapps
|-- ROOT
|-- manager
|-- host-manager
|-- work
Following is the startup/shutdown/restart script I'm using:
#!/bin/sh
if [ "$CATALINA_BASE" = "" ]; then
export CATALINA_BASE=/data/tomcat2
fi
case "$1" in
'start')
. /data/tomcat2/bin/catalina.sh start
;;
'stop')
. /data/tomcat2/bin/catalina.sh stop
;;
'restart')
. /data/tomcat2/bin/catalina.sh stop
sleep 10
. /data/tomcat2/bin/catalina.sh start
;;
*)
echo "Usage: {start|stop|restart}"
;;
esac

Thanks for pointing out that I needed tomcat-juli.jar and for the detailed
explanation of your setup; it was very helpful. By adding tomcat-juli.jar to
the instance bin directory and modifiying my startup/shutdown scripts
accordingly, I was able to get the second tomcat instance working.
I appreciate everyones help.
Best,
Ari

That being said, I start up and shut down 4 Tomcat instances when I'm working on
cluster issues. Here's a typical directory structure I use for each Tomcat
that's a part of the cluster:
deimos-host/
├── bin
│ ├── setenv.sh
│ ├── shutdown.sh
│ ├── startup.sh
│ └── tomcat-juli.jar
├── conf
│ ├── Catalina
│ │ └── localhost
│ │ ├── host-manager.xml
│ │ ├── manager.xml
│ ├── catalina.policy
│ ├── catalina.properties
│ ├── context.xml
│ ├── logging.properties
│ ├── server.xml
│ ├── tomcat-users.xml
│ └── web.xml
├── lib
├── logs
├── temp
├── temp-dir
├── watch-dir
├── webapps
│ ├── docs
│ ├── manager
│ ├── ROOT
└── work
I've left out the actual web applications and permissions.
Here's my startup.sh script for the above host.
#!/bin/bash
export CATALINA_BASE=/someplace/deimos-host
export CATALINA_HOME=/reference-place/apache-tomcat-6.0.29
$CATALINA_HOME/bin/startup.sh
The shutdown.sh script is similar.
I have a bunch of environment variables in setenv.sh. They reference where log4j
logs should go and enables JMX. Those aren't really important.
Finally, I start the entire cluster with the following script.
#!/bin/bash
( phobos-host/bin/startup.sh )
sleep 5
( deimos-host/bin/startup.sh )
sleep 5
( mars-host/bin/startup.sh )
sleep 5
( xerxes-host/bin/startup.sh )
The cluster shutdown script is similar.
There are a few things to note in the above script. The parentheses are
necessary around each startup script. If you take a look at the stock startup.sh
script in $CATALINA_HOME/bin, you'll find that the last line is:
exec "$PRGDIR"/"$EXECUTABLE" start "$@"
exec replaces the current shell. So if you write a script that tries to start
multiple Tomcats, the first time you run the stock startup.sh script, your shell
gets replaced.
I have sleep statements in my script since this is for a cluster and I don't
define a port in the Receiver element of the cluster. This allows Tomcat to find
open ports for cluster communication.
. . . . just my two cents

Which other files are needed? I tried copying all the files from the conf
directory of the base configuration, but that didn't resolve the issue
either.
Also, I have changed the shutdown port from 8005 to 8006. Any other
ideas/suggestions? Thanks.

Those two files are not sufficient.
Note, that the conf folder is read only from the second instance.
(The files in CATALINA_HOME\conf are never read).

What about the shutdown port? POssible conflict there?
