Setting up an external Zookeeper Solr Cluster

Setting up an external Zookeeper Solr Cluster

This is a step by step instruction on how to create a cluster that has three Solr nodes running in cloud mode. These instructions should work on both a local cluster (for testing) and a remote cluster where each server runs in its own physical machine. This was tested on Solr version 5.4.1 and Zookeeper version 3.4.6

Installing Solr and Zookeeper

  • Download and extract Solr:
    • curl -O http://archive.apache.org/dist/lucene/solr/5.5.3/solr-5.5.3.tgz
    • mkdir /opt/solr
