Django + Haystack + Solr Installation/Setup

Django Haystack Solr Setup

### Solr Install ###

Install pysolr and django-haystack and set up django-haystack. Setup for haystack is pretty straight forward:
https://django-haystack.readthedocs.org/en/v1.2.7/tutorial.html

Make sure you follow the haystack instructions for the correct version of haystack that you installed,
as some of the setting variables are different depending on the version.


# SSH into the server that you want to install Solr on

  ssh 192.168.1.1


# Download Solr

  sudo curl -O http://apache.mirror.vexxhost.com/lucene/solr/3.6.1/apache-solr-3.6.1.zip

  - Note: Or go here: http://lucene.apache.org/solr/ and download the latest version.

  - Note 2: Make sure you dont download the "-src" version


# Unzip the file

  sudo unzip apache-solr-3.6.1.zip

  - Note: Unzip in whichever directory, I put it in the root directory.


# Give the new folder permissions

  chmod 777 -R apache-solr-3.6.1


# cd into the example directory

  cd apache-solr-4.0.0/example


# Start the Solr Server

  java -jar start.jar


# Build the schema out for solr and save it to schema.xml

  python manage.py build_solr_schema > schema.xml

  - Note: Do this is your django project directory


# Replace the solr schema in  "apache-solr-3.6.1/example/solr/conf/schema.xml" with the one you made in the previous step

  Just copy it over transmit. the schema.mxl file might not be at this exact location, it depends on your solr version.

  java -jar start.jar


# Build the Search index

  -Note: Do this in your django project directory


# Set up Jetty

# Set up a cron job to update the search indexes

  0 */2 * * * cd DJANGO_PROJECT_PATH & PYTHON_PATH MANAGE_PATH update_index --age=<num_hours> > CRON_LOG_PATH 2>&1

  Example: This will update the index every 2 hours.
  0 */2 * * * cd /home/lift/www/eea.org/eea & /home/lift/virtualenvs/eea/bin/python /home/lift/www/eea.org/eea/manage.py update_index --age=2 > /home/lift/www/eea.org/logs/cron.txt 2>&1

can we use solr 5.4.0 with haystack?
