CouchDB is a document-oriented database with MapReduce feature. It provides a RESTful JSON API over HTTP. It offers distributed, featuring robust, incremental replication with bi-directional conflict detection and management. It is similar to MongoDB.
To install it on Mac OS X Lion, just execute this command here:
sudo port install couchdb
And after the installation this here:
sudo launchctl load -w /Library/LaunchDaemons/org.apache.couchdb.plist
To install couchdb as Service in the OS and start the couchdb daemon.Now you can open a browser and navigate to this address:
http://localhost:5984/
You should get a JSON result similar to that here:
{"couchdb":"Welcome","version":"1.1.0"}
And that’s it. CouchDB installed, up and running!
