Solr setup examples

How to setup Standalone Solr using data-driven schemaless mode.

$ mkdir $HOME/solr
$ cd $HOME/solr
$ wget https://archive.apache.org/dist/lucene/solr/5.4.0/solr-5.4.0.tgz
$ tar zxvf solr-5.4.0.tgz
$ cd solr-5.4.0

2.Start standalone Solr

$ ./bin/solr start -p 8983 -s server/solr

3.Create core

$ ./bin/solr create -c collection1 -d server/solr/configsets/data_driven_schema_configs -n collection1_configs

How to setup SolrCloud using data-driven schemaless mode (shards=1 and replicationfactor=2).

1.Download and install ZooKeeper

$ mkdir $HOME/zookeeper
$ cd $HOME/zookeeper
$ wget https://archive.apache.org/dist/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz
$ tar zxvf zookeeper-3.4.6.tar.gz
$ cd zookeeper-3.4.6
$ cp -p ./conf/zoo_sample.cfg ./conf/zoo.cfg

2.Start standalone ZooKeeper

$ ./bin/zkServer.sh start

3.Download an install Solr

$ mkdir $HOME/solr
$ cd $HOME/solr
$ wget https://archive.apache.org/dist/lucene/solr/5.4.0/solr-5.4.0.tgz
$ tar zxvf solr-5.4.0.tgz
$ cd solr-5.4.0
$ ./server/scripts/cloud-scripts/zkcli.sh -zkhost localhost:2181 -cmd clear /solr
$ ./server/scripts/cloud-scripts/zkcli.sh -zkhost localhost:2181 -cmd makepath /solr
$ cp -pr server/solr server/solr1
$ cp -pr server/solr server/solr2

Developing

1. Plugin Developement and Testing

Code

  • To get started, you'll need JRuby with the Bundler gem installed.

  • Create a new plugin or clone and existing from the GitHub logstash-plugins organization. We also provide example plugins.

  • Install dependencies

bundle install

Test

  • Update your dependencies
bundle install
  • Run tests
bundle exec rspec

2. Running your unpublished Plugin in Logstash

2.1 Run in a local Logstash clone

  • Edit Logstash Gemfile and add the local plugin path, for example:
gem "logstash-output-solr", :path => "/your/local/logstash-output-solr"
  • Install plugin
bin/plugin install --no-verify
  • Run Logstash with your plugin
bin/logstash -e 'output {solr {}}'

At this point any modifications to the plugin code will be applied to this local Logstash setup. After modifying the plugin, simply rerun Logstash.

2.2 Run in an installed Logstash

You can use the same 2.1 method to run your plugin in an installed Logstash by editing its Gemfile and pointing the :path to your local plugin development directory or you can build the gem and install it using:

  • Build your plugin gem
gem build logstash-output-solr.gemspec
  • Install the plugin from the Logstash home
bin/plugin install /your/local/plugin/logstash-output-solr.gem
  • Start Logstash and proceed to test the plugin

Contributing

All contributions are welcome: ideas, patches, documentation, bug reports, complaints, and even something you drew up on a napkin.

Programming is not a required skill. Whatever you've seen about open source and maintainers or community members saying "send patches or die" - you will not see that here.

It is more important to the community that you are able to contribute.
