Neo4j Database Recovery

In the rare case of having problems with a corrupt Neo4j database, try the following steps (GNU/Linux and OS X only):

1. Download the Neo4j server in the version Structr is using.

   wget http://dist.neo4j.org/neo4j-enterprise-2.2.8-unix.tar.gz

2. Unpack the downloaded file

   tar xvf neo4j-enterprise-2.2.8-unix.tar.gz

3. Enter the directory just created

   cd neo4j-enterprise-2.2.8

4. Configure Neo4j to access your database

   Copy the db/ directory of your Structr instance to data/graph.db or modify the parameter org.neo4j.server.database.location in conf/neo4j-server.properties to reflect the location of your Structr db/ directory.

5. Start Neo4j

   bin/neo4j start

6. Wach the log file

   Depending on whether you copied the database or edited the configuration, it’s either
   tail -100f data/graph.db/messages.log
   or
   tail -100f <structr-main-directory>/db/messages.log

7. Stop Neo4j

   bin/neo4j stop

If the database doesn’t start properly, try downloading an older version and repeat the procedure.
