=Install Apache Solr under Ubuntu=

This Tutorial describes how to install a local Tomcat Server with the newest Solr Version.

==Java Runtime Environment installieren==

At First we need a Java Runtime Environment. You can use OpenJdk or Oracle (Sun) Java Version 6+

        aptitude install default-jre

or

        apt-get install openjdk-6-jdk

==Tomcat downloading and install==

At Firts we need the newest Tomcat Version from Apache.org. If this link isn't working anymore go to tomcat.apache.org

        cd /opt
        wget http://artfiles.org/apache.org/tomcat/tomcat-7/v7.0.23/bin/apache-tomcat-7.0.23.tar.gz
        tar xvfz apache-tomcat-7.0.23.tar.gz
        ln -s apache-tomcat-7.0.23 tomcat
        rm apache-tomcat-7.0.23.tar.gz

==Solr downloading and install==

Now we need the Newest Version of Solr. You can find it on the Apache Site (http://www.apache.org/dyn/closer.cgi/lucene/solr/)

        cd /opt
        wget http://apache.imsam.info//lucene/solr/3.5.0/apache-solr-3.5.0.tgz
        tar xvfz apache-solr-3.5.0.tgz
        rm apache-solr-3.5.0.tgz

Now we deploy Apache Solr to the Tomcat Server. Copy the war File from the "dist" dir to your Tomcat webapps folder.

        cd /opt
        cp apache-solr-3.5.0/dist/apache-solr-3.5.0.war tomcat/webapps/solr.war

Now copy the Multicore Example to your Solr Folder /opt/solr. Now you can delete the other solr files, we dont need them.

        cd /opt
        cp -R apache-solr-3.5.0/example/multicore/ solr
        rm -R apache-solr-3.5.0

Now we can start your new Tomcat server.

Note: It's important to strat the Tomcat Server from /opt, otherwise the Tomcat Server will not find your solr dir.

        cd /opt
        ./tomcat/bin/startup.sh

Now you can see your solr Cores and the admin interface under the url http://yourserver:8080/solr 

Your Solr Server is now ready to use, but you should maybe add some security configuration

==Secure your Installation==

Your have just to do a few steps to scure your server.

Move your Data:

Create a new dir and change it in your Solr config. If you use 2 cores you have to change it for eache of them:

        mkdir /var/solr
        vi /opt/solr/solr.xml

bevore :

        <core name="core-0" instanceDir="core-0" />
        <core name="core-1" instanceDir="core-1" />

after:

        <core name="core-0" instanceDir="core-0" dataDir="/var/solr/core-0" />
        <core name="core-1" instanceDir="core-1" dataDir="/var/solr/core-1" />

==Tomcat logging.properties:==

Your Logging Properties should be reduced to SEVERE, otherwise it will be realy big realy fast.

Edit the logging.properties File in /opt/tomcat/conf 

        vi /opt/tomcat/conf/logging.properties

Default is "FINE". You should change it from "FINE" to "SEVERE"
