If this is your first install, automatically load ElasticSearch on login with:
mkdir -p ~/Library/LaunchAgents
ln -nfs #{plist_path} ~/Library/LaunchAgents/
launchctl load -wF ~/Library/LaunchAgents/#{plist_path.basename}
If this is an upgrade and you already have the #{plist_path.basename} loaded:
launchctl unload -w ~/Library/LaunchAgents/#{plist_path.basename}
ln -nfs #{plist_path} ~/Library/LaunchAgents/
launchctl load -wF ~/Library/LaunchAgents/#{plist_path.basename}
If upgrading from 0.18 ElasticSearch requires flushing before shutting
down the cluster with no indexing operations happening after flush:
curl host:9200/_flush
To stop the ElasticSearch daemon:
launchctl unload -wF ~/Library/LaunchAgents/#{plist_path.basename}
To start ElasticSearch manually:
elasticsearch -f -D es.config=#{prefix}/config/elasticsearch.yml
See the 'elasticsearch.yml' file for configuration options.
You'll find the ElasticSearch log here:
open #{var}/log/elasticsearch/#{cluster_name}.log
The folder with cluster data is here:
open #{var}/elasticsearch/#{cluster_name}/
You should see ElasticSearch running:
open http://localhost:9200/
