Tomcat

A nice guide to installing Tomcat by Digital Ocean: https://www.digitalocean.com/community/tutorials/how-to-install-apache-tomcat-7-on-ubuntu-14-04-via-apt-get

sudo apt-get install tomcat7

Now visit http://localhost:8080. You should see something like this:

Tomcat Goodies

Install Tomcat goodies (listed on the default Tomcat page pictured above):

sudo apt-get install tomcat7-docs tomcat7-admin tomcat7-examples

When you do that, the links listed on localhost:8080 (to documentation, examples, etc) will now work.

Showing Tomcat Where Java Is

instructions modified from http://hongru.hou.io/blog/2013/01/07/How-to-install-GeoServer-on-Ubuntu-12.04/

We will need to edit the Tomcat config file:

sudo vim /etc/default/tomcat7

Insert the line that tells Tomcat where Java is:

JAVA_HOME=/usr/lib/jvm/openjdk-7-jdk

And then we restart Tomcat with the new configuration:

sudo /etc/init.d/tomcat7 restart

Java Goodies

sudo apt-get install default-jdk ant git

Geoserver

Download

Download the Geoserver WAR file (this is the web applet that will be run by Tomcat).
