Running two instances of Solr on Tomcat on one Ubuntu server.
This post deals specifically with the aptitude packages tomcat6 and solr-tomcat, but it might be helpful in general. You can basically copy and paste the following (as root):
cp /etc/tomcat6/Catalina/localhost/solr.xml /etc/tomcat6/Catalina/localhost/solr_2.xml nano /etc/tomcat6/Catalina/localhost/solr_2.xml
Make it look like this:
<Context path="/solr_2" docBase="/usr/share/solr_2" debug="0" privileged="true" allowLinking="true" crossContext="true"> <Resources className="org.apache.naming.resources.FileDirContext" allowLinking="true" /> <Environment name="solr/home" type="java.lang.String" value="/usr/share/solr_2" override="true" /> </Context>
Then:
cp -rf /usr/share/solr /usr/share/solr_2 cp -rf /etc/solr /etc/solr_2 rm /usr/share/solr_2/WEB-INF/web.xml ln -s /etc/solr_2/web.xml /usr/share/solr_2/WEB-INF/web.xml rm /usr/share/solr_2/conf ln -s /etc/solr_2/conf /usr/share/solr_2/conf nano /etc/solr_2/conf/solrconfig.xml cp -rf /var/lib/solr /var/lib/solr_2 chown -R tomcat6:tomcat6 /var/lib/solr_2/data chmod -R 770 /var/lib/solr_2/data
chown tomcat6:tomcat6 dataimport.properties
service tomcat6 restart
Now you should have two solr instances running at localhost:8080/solr and localhost:8080/solr_2 respectively.
