curl http://archive.apache.org/dist/lucene/solr/4.10.3/solr-4.10.3.tgz | tar xz
cp ~/solr-4.10.3/example/lib/ext/* /usr/share/tomcat7/lib/
cp ~/solr-4.10.3/dist/solr-4.10.3.war /var/lib/tomcat7/webapps/solr.war
cp -R ~/solr-4.10.3/example/solr /var/lib/tomcat7
chown -R tomcat7:tomcat7 /var/lib/tomcat7/solr
