Neo4j AMI on AWS database path change

(Msrviking) #1

Hi, I am trying to change the database path by editing neo4j.template on Neo4j AMI on AWS however the neo4j instance is refusing to start after the change.

I get the error consistently that neo4j is starting, and stopping. I looked for anything specific in neo4j logs (debug.log) however couldn't read much from the logs on why the neo4j is failing. I get the error "Connection refused", and I understand it could be because the neo4j instance isn't starting.

The parameters I have changed are and to values as below

Can someone help me with what I am missing?

Thanks in advance.

Hi mrsviking,

Attaching the logs would help, but I can make a couple suggestions.

  1. Instead of the whole path make dbms.active_database=graph.db
    this is much closer to the original directory structure.
  2. Ensure the the Neo4j user owns /disk1/var/lib/neo4j and all subdirectories beneath it.
  3. Copy the dbms folder from the original /var/lib/neo4j/data to the new location.

Make sure Neo4j owns all the files once you are done copying (e.g. sudo chown -R neo4j:neo4j )

Thank you David. This worked. I had some issues getting the authentication, but then figured out that the dbms didn't have the auth file when I created the new directory path. Now all set.
