Apache Solr for Bitnami Cloud Hosting

Apache Solr is a popular open source enterprise search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, rich document (e.g., Word, PDF) handling, and geospatial search. Solr is highly scalable, providing distributed search and index replication, and it powers the search and navigation features of many of the world's largest internet sites.

How to configure the Apache Solr server?

Obtain example configuration files by following these steps:

$ sudo /opt/bitnami/ctlscript.sh stop solr
  • Change directories to locate the files:

      $ cd /opt/bitnami/apache-solr
    
  • Create Solr home directory /opt/bitnami/apache-solr/example/techproducts/solr by executing the following command:

      $ sudo ./bin/solr -e techproducts
    

This action creates a set of example configuration files in /opt/bitnami/apache-solr/example/techproducts/solr/techproducts/conf. These are configuration references. Modify these files depending on your server requirements.

  • Access the Solr administration interface via SSH or by opening the port 8983 in the server firewall. Refer to the FAQ for more information on how to configure your server firewall.

How to enable the Apache Solr logs?

The Apache Solr log files are not enabled by default after version 3.x. To enable the log files, uncomment the following section in the /opt/bitnami/apache-solr/server/etc/jetty.xml file. Remember to restart the server for your changes to take effect.
