Well, well, well...
The stuff is not so hard after all.
I have a single Apache runnin' and a single Tomcat runnin' too.
I think the best way is to make instances of Tomcat.
Yu will have one binary code runnin' and many instances, on different port
each..., easyly usefull by their own.
I mean every user will have the opportunity to start/stop his own instance
without disturbin' all the other.
If it is what yu want so lets's go.
Tomcat can be instantiated easily:
For each user let's say in their HOME dir call user_home, just create a WebApp
folder like below:
$user_home/WebApp containing
./conf
./logs
./webapps
./work
Just set the rights correctly for that user.
In the conf folder cp the $CATALINA_HOME/conf files yu need ( server.xml,
web.xml, tomcat_users.xml ...)
modify conf/server.xml to set different non-used ports for yur stuff
for instance :
<Server port="8015" shutdown="SHUTDOWN" debug="0">
../..
<Connector className="org.apache.catalina.connector.warp.WarpConnector"
port="8018" minProcessors="5" maxProcessors="75"
enableLookups="true" appBase="webapps"
acceptCount="10" debug="0"/>
In the bin folder create the files to start/stop the instance:
#!/bin/sh -x
# -----------------------------------------------------------------------------
# Start script for the CATALINA Server
#
# $Id: shutdown.sh,v 1.1.4.1 2002/01/30 18:10:40 patrickl Exp $
#
# V1.0 021902 Adapted for user1 by Admin on 02/19/2002
# -----------------------------------------------------------------------------
JAVA_HOME=/usr/j2se
CATALINA_HOME=/usr/local/Tomcat
CATALINA_BASE=/export/home/user1/AppWeb
export JAVA_HOME CATALINA_HOME CATALINA_BASE
BASEDIR=`dirname $0`
$CATALINA_HOME/bin/catalina.sh start "$@"
#
Make the same for stop replacing start by ... stop ! yes yu get it, boy..
Yu can modify the user_home/conf/server.xml to put logs at the right place.
Yu can also allow the manager application too!
Well i do it with an instance of Apache via mod_webapp under TC4.0.2/Warp1.0.2
without any pbs..
Hope this help.
Regards.
