Question
can't we create multiple instances of tomcat7 in ubuntu?
Hi,
I created duplicate instance of tomcat by creating a directory under /var/lib/tomcat7-a. Later i updated server.xml with new port i copied catalina.properties file and web.xml.
finally created init service for tomcat7-a and updated with defaults.
I tried to start the program when i pose a command like,
service tomcat7-a start
it gives “tomcat7-a not installed”
means,
it stops at below script in init program,
if [ ! -f “$CATALINAHOME/bin/bootstrap.jar” ]; then
logfailure_msg “$NAME is not installed.... kjfkdj”
exit 1
fi
what should i do now?

In your case, note that $CATALINA_BASE should be different from $CATALINA_HOME, where the former is where you created your instance and the latter is where tomcat7 is installed. Usually, $CATALINA_HOME is installed in /usr/share/tomcat7 on Ubuntu.
I configured the
$ cd /var/lib/
$ sudo mkdir tomcat7-a
$ cd /var/lib/tomcat7-a
$ sudo mkdir conf temp webapps work logs
$ sudo mkdir conf temp webapps work logs
$ cd ..
$ sudo chown -R tomcat7:tomcat7 tomcat7-a
$ sudo ln- s /var/lib/tomcat7/conf/catalina.properties /var/lib/tomcat7-a/conf
$ sudo ln- s /var/lib/tomcat7/conf/web.xml /var/lib/tomcat7-a/conf
$ sudo ln- s /var/lib/tomcat7/conf/policy.d/ /var/lib/tomcat7-a/conf
$ sudo cp /var/lib/tomcat7/conf/server.xml /var/lib/tomcat7-a/conf/
–>changed the port 8080 to 8081 in tomcat7-a server.xml
$ cd /etc/init.d/
$ sudo cp tomcat7 tomcat7-a
DESC=”Tomcat servlet engine”
CATALINABASE=/var/lib/$NAME
CATALINAPID=”/var/run/$NAME.pid”
$ sudo service tomcat7-a start
$ sudo update -rc.d tomcat7-a defaults
Now, when i try to start the new instance it kicks with an error like above what i mentioned. Now i changed the CATALINABASE=/var/lib/tomcat7-a and CATALINAHOME=/usr/share/tomcat7 in new instance init config.
Now it is starting when i use service tomcat7-a start. But when i go to browser it kicks an error like,
http://localhost:8081/ Failed to load resource: the server responded with a status of 404 (Not Found)
am i did anything wrong in config? ratherthan displaying tomcat manager page it displaying blank screen.. when i go to console i see this error.
