Solr Cloud Configuation Steps

Download Solr 4.3.0 (I have tested on 4.3.0, latest version is 6.3.0 )


First configure solr.xml file

Note: we need 4 solr and 3 zookeeper server for solr cloud (zookeeper must be odd number, minimum three zookeeper require. only one zookeeper is not allowed. Among 4 solr, First one is your Shard1, 2nd solr is your Shard2, 3rd is Replica of Shard1 and 4th is Replica of Shard2 vice versa).

Configure Solr.xml file in all solr servers....

Location of solr.xml file: Solr server Directory/solr/solr.xml

Host: Give IP Address here (Ensure that your IP must be given to your system before assigning it to solr).
