How do you set up neo4j to work with Google Compute Engine?

I'm wondering how one would get neo4j to work with Google Compute Engine. Has anybody done this? What problems did you encounter?

Here you go,

Basic Setup

Configuration for GCE

Play around

  • Start neo4j server ./bin/neo4j start
  • Check your running instances @ http://IP_ADDRESS:7474/

Once py2neo Installed and server started, try some pycode to test it

>> from py2neo.neo4j import GraphDatabaseService, CypherQuery
>> # Set up a link to the local graph database.
>> # When () left blank defaults to http://localhost:7474/db/data/
>> graph = GraphDatabaseService('http://IP_ADDRESS:7474/db/data/')
>> CypherQuery(graph, "CREATE (n {name:'Example'}) RETURN n;").execute()

Above python setup / code, you can use it in GAE as well.

Edit: Appengine + Neo4j

from py2neo import neo4j
GRAPH_DB = neo4j.GraphDatabaseService(
        'http://uname:psswd@localhost:7474/db/data/')
if IS_PROD:
    GRAPH_DB = neo4j.GraphDatabaseService(
        'http://uname:psswd@host:port/db/data/')

def _execute(query):
    """Execute all neo4j queries and return list of Record objects.

    Returns:
      Returns list of Record objects.
    """
    try:
        result = neo4j.CypherQuery(GRAPH_DB, query).execute()
        # logging.info(result.data)
        return result
    except neo4j.CypherError as error:
        logging.error(error.exception)
    except DeadlineExceededError as dead:
        logging.warn(dead)
    except urlfetch_errors.InternalTransientError as tra_error:
        logging.warn(tra_error)
    except httplib.HTTPException as exp:
        logging.warn(exp)
    except neo4j.http.SocketError as soc:
        logging.warn(soc)

the easiest and the safest way is to use docker neo4j image

and this is docker docs, to install and deploy on google compute engine
