Go to apache site and download solr version (solr-4.7.2) and extract to /opt/ solr directory in root (/) dir and provide 755 recursive permission. * 3. install latest java jdk version, as solr needs java. needs sudo user to install. * sudo -s * provide sudo password to login. than you will be logged in as root user. * install java jdk * sudo apt-get install jdk * confirm java installed * javac or java –version * 3. change directory to solr * cd /opt/solr/solr/bin * 3. start solr server * java -jar start.jar * 4. locate your browser url * [http://localhost:8983/solr/](http://localhost:8983/solr/) * you will be able to see solr admin , cool. * 5. Now you will need to fix * /opt/solr/solr/collection1/conf/solrconfig.xml file * open and change this ‘4.7’ to * 4.6 * It will match the luence version to our solr installtion setup. we are all completed now. if you will not do this it will throw error in indexing ‘lazy_load_error’ java. * 6. configure wpsolr with solr details: * Index name: whateveer you want Solr Protocol: http Solr host: localhost Solr port: 8983 Solr path: /solr * And click “Check Solr Status, then Save this configuration” button a green arrow will show, means all cool. now check uncheck page,post ,cateogry , taxonomy to index, than go to “solr indexing batch” tab and click “Synchronize WordPress with ‘Config’ ” button it will index all new changes to solr. * 7.
