How to setup a simple Ubuntu Server Tomcat cluster on VirtualBox for testing?

http://serverfault.com – I am looking for a step by step instructions to setup at leat two (and later more) simple Ubuntu Virtual Core 12.10 Server VMs on Oracle VirtualBox under Windows 7 64bit. The test setup would be: Apache HTTP server on the Windows host acting as a Load Balancer. The result will be that going to http://localhost:8080 would balance between two nodes and prove session replication. Two lean, small footprint Ubuntu Server guest nodes with Java 7 and Tomcat 7. The intention is to help everyone doing High Availability / Load Balancing development and testing to create a reasonable environment on (HowTos)

simple jsp problem. 2 years 42 weeks ago

I have my jsp page located at /install/apache-tomcat-5.5.29/webapps/jsp-examples/light/login.jsp

There fore i will have to use following url to access it. http://localhost:8080/jsp-examples/light/login.jsp

How would i make this little shorter like. http://localhost:8080/login.jsp.

I m using apache tomcat server 5.5.29.

I get the following error when I run my JSP file in Eclipse-Juno with Tomcat v7:

'starting Tomcat v7.0 server at localhost' has encountered a problem. Port 8080 required by Tomcat v7.0 server at localhost is already in use. The server may already be running in another process, or a system process may be using the port.

forward port 80 to 8080 failed 15 weeks 3 days ago

I am trying to forward a port from 80 to 8080 (default to tomcat).

I have an application running on tomcat and fronted with Apache.

I am trying to set up a high availability setup(not load balancing, only HA) with 2 tomcat servers. When I google for information, I get tons of links with apache+HAProxy+keepalived setup for linux fronted by a virtual IP. This seems simple enough.

I have setup Solr on a Ubuntu server and can reach the "Tomcat Web Application Manager" application via http://localhost:8080/manager/html and execute solr queries via http://localhost:8080/solr/core_things/select/?q=name:bloggs.

How can I get the manager application to run on a different port than Solr itself?

(I have setup http authentication for the manager application, however I'd prefer it

Tomcat7 is tied to a shell 14 weeks 2 days ago

When my ubuntu server boots up, tomcat7 does not run (I cannot open localhost:8080) When I ssh into my server, I am able to open localhost:8080 When I close my ssh connection, tomcat stops working again

I have this startup script in the init.d:

export JAVA_HOME=/usr/lib/jvm/java-7-oracle export CATALINA_HOME=/home/knowroaming/apache-tomcat-7.0.34 /etc/init.d/tomcat7.sh start

I also have symb

Currently we have the following setup.

Hardware Load Balancer (LB) Box A running Tomcat on 8080 (TA) Box B running Tomcat on 8080 (TB)

TA and TB are running behind LB.

For now it's pretty complicated and manual job to take Box A or Box B out of LB to do the zero downtime deployment.

I am thinking to do something like this:

Hardware Load Balancer (LB) Box A running Nginx on 8080 (NA) Box A
