wget http://apache.cict.fr/lucene/solr/3.6.0/apache-solr-3.6.0.zip
unzip apache-solr-3.6.0.zip
cd apache-solr-3.6.0/

# copy the main app to the "webapps" folder
cp dist/apache-solr-3.6.0.war /var/lib/tomcat6/webapps/solr.war

# this also creates a "solr" directory here within 60s:
# /var/lib/tomcat6/webapps/solr
cp -rf example/solr/* /var/lib/tomcat6/webapps/solr/
chown -R tomcat6:tomcat6 /var/lib/tomcat6/webapps/solr

# stop tomcat
/etc/init.d/tomcat6 stop

# create our config file
touch /etc/tomcat6/Catalina/localhost/solr.xml
chown tomcat6:tomcat6 /etc/tomcat6/Catalina/localhost/solr.xml
nano /etc/tomcat6/Catalina/localhost/solr.xml

# and fill it with the following configuration :

<Context docBase="/var/lib/tomcat6/webapps/solr.war" debug="0" privileged="true" allowLinking="true" crossContext="true">
<Environment name="solr/home" type="java.lang.String" value="/var/lib/tomcat6/solr" override="true" />
</Context>

# edit the data path
mkdir -p /var/lib/solr/data
chown -R tomcat6:tomcat6 /var/lib/solr/data
nano /var/lib/tomcat6/webapps/solr/conf/solrconfig.xml

# edit the path <dataDir>/var/lib/solr/data</dataDir>

# start tomcat
/etc/init.d/tomcat6 start

# this link should now work:
http://192.168.1.35:8080/solr/admin/

# Disable excessive double logging to .out file

----------------------------
# MULTI-core setup
----------------------------
# stop tomcat
/etc/init.d/tomcat6 stop

# edit the config file:
nano /var/lib/tomcat6/webapps/solr/solr.xml

# add the following replacing the existing data

  <cores adminPath="/admin/cores" defaultCoreName="core0">
    <core name="core0" instanceDir="core0" />
    <core name="core1" instanceDir="core1" />
  </cores>

# create default directories
mkdir core0 core1

#copy or create the magento conf folder in each
cp -R /root/magesolrtemp/conf /var/lib/tomcat6/webapps/solr/core0/
cp -R /root/magesolrtemp/conf /var/lib/tomcat6/webapps/solr/core1/

# start tomcat
/etc/init.d/tomcat6 start
