<solr persistent=”true”>

     <cores adminPath=”/admin/cores” defaultCoreName=”collection1”>

           <core name=”collection1”instanceDir=”collection1”/>

</cores>

</solr>

Copy schema.xml, solrconfig.xml to <solr.home>/<collectiondir>/conf

 

Modify /etc/default/jetty file, add  -Dsolr.solr.home=xxx

 

Tomcat:

Change tomcat server.xml: connector’s url encoding toUTF-8

<Connector port=”8080” protocol=”HTTP/1.1”connectionTimeout=”20000”  redirectPort=”8443”URIEncoding=”UTF-8”/>

 

Create solr.xml in $TOMCAT_HOME/conf/Catalina/localhost

<Context path=”/solr” docBase=”/usr/share/tomcat/webapps/solr.war”debug=”0” crossContext=”true”>

           <Environment name=”solr/home”type=”java.lang.String” value=http://www.mamicode.com/”usr/share/solr” override=”true”/>

</Context>

 

Copy schema.xml, solrconfig.xml, solr.xml etc to<solr.home> directory

<solr persistent=”true”>

     <cores adminPath=”/admin/cores” defaultCoreName=”collection1”>

         <core name=”collection1”instanceDir=”collection1”/>

</cores>

</solr>

Copy schema.xml, solrconfig.xml to <solr.home>/<collectiondir>/conf

 

        

Solr cloud requirement:

_version_  field

<field name=”_version_” type=”long” indexed=”true”stored=”true” multiValued=”false”/>

 

solr.ReplicationHandler

<requestHandler name=”/replication” class=”solr.ReplicationHandler”/>

 

solr.RealTimeGetHandler

<requestHandler name=”/get” class=”solr.RealTimeGetHandler”>

     <lstname=”defaults”>

           <str name=”omitHeader”>true</str>

</lst>

</requestHandler>

<updateLog>

    <strname=”dir”>${solr.data.dir:}</str>

</updateLog>

 

solr.xml

<solr persistent=”true”>

<cores adminPath=”/admin/cores … host=”localhost”hostPort=”xxx” zkClientTimeout=”xxxx”>

</solr>

 

Directory Implementation:

              <directoryFactory name=”DirectoryFactoryclass=”xxxxxxx”/>

             

Solr.StandardDirectoryFactory

Solr make  decision on underlining implementation

Solr.SimpleFSDirectoryFactory

Does not scale  well with high number of threads

Solr.NIOFSDirectoryFactory

Scale well with  many threads, but does not work well on Windows

Solr.MMapDirectoryFactory

Good for 64 bit  linux system  if near realtime  searching is not needed

Solr.NRTCachingDirectoryFactory

Good for near  real-time indexing and searching

Solr.RAMDirectoryFactory

Entirely in  memory and not support replication

Used for auto-completion  or unit testing
