Configuring Apache Solr for your Drupal site
Make a copy of the Solr core to be used for Drupal sites
cp -r example/ drupal/
Create cores for your sites. Every core is an instance of a Drupal site:
cd drupal/multicore
sudo cp -r core0 MYSITENAME
Edit the solr.xml to add your new core:
sudo vim solr.xml
and add a new core similar to:
<core name="My Site Name" instanceDir="MYSITENAME" />
Replace the default Solr configuration with the Drupal Solr configuration provided from the Search API Solr Search module.
sudo rm -r MYSITENAME/conf
sudo cp -r /PATH/TO/DRUPAL/sites/all/modules/contrib/search_api_solr/solr-conf/5.x /usr/local/solr/drupal/multicore/conf/MYSITENAME/conf
Start Solr
cd ..
java -Dsolr.solr.home=multicore -jar start.jar
Create Solr user
sudo useradd -d /usr/local/solr -M -s /usr/sbin/nologin solr
sudo chown -R solr:root /usr/local/solr
Add Solr as a Service
Download the init.d script to start Apache Solr. Thanks to 2bits.
wget http://2bits.com/sites/2bits.com/files/solr-init.d.sh_.txt
sudo mv solr-init.d.sh_.txt /etc/init.d/solr
Edit the file to suit your environment and change the SOLR_HOME=/opt/solr/example environment variable (line 18) to /usr/local/solr/drupal
sudo vim /etc/init.d/solr
Replace line 18 to be:
SOLR_HOME=/usr/local/solr/drupal
Make the service to work properly:
sudo chmod a+rx /etc/init.d/solr
sudo update-rc.d solr defaults
Access Solr
Your Solr URL will be: http://localhost:8983/solr/#
