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

rameezts / badbots.lst
Created October 19, 2015 07:14
A list of bad and "good" User-Agents (robots) that are worth blocking with haproxy. This will help stop your bandwidth being used up by these crawlers. I continually add to this list at least once a week. This is the haproxy rule I use. acl badbots hdr_reg(User-Agent) -i -f /etc/haproxy/badbots.lst block if badbots
# -----------------------------------------------------------------
# User-Agent strings that are worth blocking with the following rule
# in haproxy to prevent your content being stolen, stop spammers and
# to limit your bandwidth usage.

# acl badbots hdr_reg(User-Agent) -i -f /etc/haproxy/badbots.lst
