How to run Solr 4 in Tomcat locally?

Question

I\'ve been trying to set up Solr 4.3 on my home PC (in Tomcat 7) but it doesn\'t run. I have set up Tomcat and deployed the solr.war file which both unpacks and sho

The easiest way to get started with Solr on Tomcat is to use HDS (Heliosearch Distribution for Solr), a Tomcat/Solr distribution

It's a super-set of Apache Solr, containing an additional "server" directory that is a pre-configured (threads, logging, connection settings, message sizes, etc) Tomcat based Solr server.

Some other implementation notes:

• start scripts can be run from anywhere, and allow passing JVM args on command line (just like jetty, so it makes it easier to use)
• start scripts work around known JVM bugs
• start scripts allow setting port from command line, and default stop port based off of http port to make it easy to run multiple servers on a single box)
• zkcli, the start script for the solr zookeeper tool, will auto-explode the WAR if necessary
• the "server" directory has been kept clean but stuffing all of tomcat under the "server/tc" directory

To start:

$ cd server
$ bin/startup.sh

To start on a different port (e.g. 7574):

$ cd server
$ bin/startup.sh -Dhttp.port=7574

To shut down:

$ cd server
$ bin/shutdown.sh -Dhttp.port=7574

The scripts even accept -Djetty.port=7574 to make it easier to cut-n-paste from start examples using jetty. The "example" directory is still there too, so you can still run the jetty based server if you want.
