Installing neo4j in openshift

While I run sh neo4j console inside the /neo4j/versions/2.1/neo4j-2.1/bin. I get the following error:

WARNING: Max 16384 open files allowed, minimum of 40 000 recommended. See the Neo4j manual.

It seems you put in a shell variable Caused by: java.lang.NumberFormatException: For input string: ""${OPENSHIFT_NEO4J_DB_PORT}"" in Neo4j's neo4j-server.properties which is not supported.

Try to modify your config script to rather replace the port inline in the config file, like this:

sed -i -e "s|org.neo4j.server.webserver.port=.*|org.neo4j.server.webserver.port=${OPENSHIFT_NEO4J_DB_PORT}|g" $NEO4J_HOME/conf/neo4j-server.properties

Seems like you've hit the max files limit. This article talks about it in relation to Neo4j:

Neo4j WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual

Specifically you would up the numbers in /etc/security/limits.conf. You may need to restart.

This seems to be possible on OpenShift:
