Solr 3.x and Tomcat setup tutorial

There is a good tutorial on solr's official site on Solr with jetty but I wouldn't find a good instruction on Solr with Tomat setup thats clean and easy. So here is my instruction.

1. download solr ( we are at version 3.x.x)
2. extra files    (tar -zxvf apache.solr.blabla.tar)
3. create solrHome folder
4. go to the upzipped solr directory and copy dist/apache.solr.3.x.x.war to solrHome
5. rename that file in solrHome from apache.solr.3.x.x.war to solr.war
6. download tomcat and modify server.xml as in 7
7.       <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">
                <Context docBase="/home/ec2-user/sandbox/solrHome/solr.war" path="/solr" reloadable="true" unpackWAR="false">
                        <Environment name="solr/home" type="java.lang.String" value="/home/ec2-user/sandbox/solrHome/" override="true" />
                </Context>

      </Host>
8. copy folders and files below  to solrHome folder also make a folder name "data" too.
conf, example, exampledocs, start.jar
these things can be found in the solr distribution tar file downloaded.

9. test solr.
go to http://localhost:8983/solr/admin/
make sure server is up and running.

10. index the monitor data 
-data are in xml format, if we want to add more data, modify the solrconfig and schema.xml files
-to fit the new data format. this is actually very simple.

cd /home/ec2-user/sandbox/solrHome/exampledocs
user:~/solr/example/exampledocs$ java -jar post.jar solr.xml monitor.xml
make sure not error from catalina.out.

11.
http://localhost:8983/solr/browse
check interface. play with it, click it. no error.

12
index all data.
java -jar post.jar *.xml

13
http://localhost:8983/solr/browse
check interface. play with it, click it. no error. more data.

------------------
command to delete all index

java -Ddata=args -Dcommit=no -jar post.jar "<delete><query>*:*</query></delete>"

java -Ddata=args -Dcommit=no -jar post.jar "<commit/>"

java -Ddata=args -Dcommit=no -jar post.jar "<optimize/>"
