I'm trying to load the CSV file in to Neo4j. But it was throwing error like this
Couldn't load the external resource at: file:/home/trainings/Desktop/neo4j-community-3.0.6/import/home/trainings/Desktop/neo4j_module_datasets/terrorist_data_subset.csv
I tried changing the neo4j.conf file. I have changed
dbms.directories.import=import
dbms.security.allow_csv_import_from_file_urls=true
even though im facing the error.
It's a little bit old post but I would like to share answer.
On Ubuntu linux neo4j version 3.2.2 open the conf from /etc/neo4j/neo4j.conf.
Find the line dbms.directories.import. Modify this path to change the default import location or comment out to load using the absolute path from '/'.
Then add the file path in query as below.
LOAD CSV FROM 'file:///artists.csv' AS line CREATE (:Artist { name: line[1], year: toInt(line[2])})
Comment out this config line: dbms.directories.import=import.
Just by placing the .CSV in to Import folder we can able to load the data into Neo4j
If you comment out the dbms.directories.import=import (located within /etc/neo4j/neo4j.conf), this allows system-wide access from neo4j dangerous, but maybe fine if it is only run on a personal machine.
To enable changes you must then kill all neo4j processes and restart the server pkill -u neo4j ; sudo neo4j start. When loading you should get something similar to:
Active database: graph.db
Directories in use:
home: /var/lib/neo4j
config: /etc/neo4j
logs: /var/log/neo4j
plugins: /var/lib/neo4j/plugins
import: NOT SET
data: /var/lib/neo4j/data
certificates: /var/lib/neo4j/certificates
run: /var/run/neo4j
Note the NOT SET in the import row.

I have a CSV file to contains some nodes, and I want to load it into neo4j through Neo4j Desktop, but got the following error message:
Invalid URL '/Users/nlp/social_graph/graph-nodes.csv': no protocol: /Users/nlp/social_graph/social-nodes.csv
What's the error? Note that before I run the command in the browser, the database is empty. How to load the database?
EDIT: Did some search and added 'file:///' to the file path, this time I got another message:
Couldn't load the external resource at: file:/Users/congminmin/Library/Application%20Support/Neo4j%20Desktop/Application/neo4jDatabases/database-fdb13bea-33f7-409b-a6bd-387a25a679e6/installation-3.5.12/import/Users/congminmin/social_graph/social-nodes.csv
The easiest would be to copy your cv file into the import directory under your neo4j installation directory. Then use file:///social-nodes.csv In your LOAD CSV command.
Find more details here: https://neo4j.com/developer/guide-import-csv/
I know it's late, but if you are using neo4j on docker, the import folder path is as follows:
/var/lib/neo4j/import
You can create a volume that bounds to the import directory. After mounting, copy your local files to your mounted directory, then use file:///file-name in your LOAD command.
I have created a graph database within Neo4j Desktop (version 1.1.10) I wish to export that as a Cypher file.
How do I do that? I can't see any command within the app for export a Cypher file.
You can try following the documentation here: Neo4j - Export a (sub)graph to Cypher script and import it again
First, install the apoc procedure library, and add it into the plugins directory.
Second, run Neo4j as an administrator. If not, Neo4j doesn't have permission to write files.
Before starting Neo4j, edit the neo4j.conf file and add this line:
apoc.export.file.enabled=true
Then, start Neo4j, and in the Neo4j browser, execute the following command:
CALL apoc.export.cypher.all("export.cypher",{})
This will store the whole database in the file "export.cypher".
$ neo4j version
neo4j 3.3.4
Host machine

Data Import
neo4j-admin import --database=actors.db --nodes movies.csv --nodes actors.csv --relationships roles.csv
after I changes to neo4j.conf as follows:
#dbms.active_database=graph.db
# changed into
dbms.active_database=actors.db
The server still points to graph.db.
I tried to restart the neo4j service to see if it will help
$ sudo service neo4j restart
However, neo4j.conf gets fully reset, and it is reverted back to
#dbms.active_database=graph.db
what is the proper step by step solution to change neo4j.conf?
Can't comment because I don't have enough reputation points... but did you ever figure this out? I've been running into the same issue.
I overwrite the neo4j.conf file, but everytime I restart the service with:
$ sudo service neo4j restart
The neo4j.conf file goes back to how it was
Update: I was able to figure this out. Chances are you have a neo4j.template file which is used to create the neo4j.conf file each time the database is reset. If you edit that, you should be good to go.
I also ran into same issue. When I dig more I found the answer. It is happening when I am trying to runNeo4J server on aws ec2 instance using custom community ami provided by Neo4j. There is a script having name pre-neo4j.sh which is configured to run on every restart of Neo4j service. Inside that script, it is replacing neo4j.conf on every restart of service with some configured template to preserve public-ip or anything like that.
I created a database Neo4j on a PC, with many relationships, node, etc
how to move/ copy the database from this pc to another?
thanks for the help

update1: I have tried to found conf/neo4j-server.properties but i don't have...
this is a screenshot of my folder ne04j (It is in Windows document Folder)

Neo4J databases live in your filesystem, you can simply make a copy of the folder in which your Neo4J data is stored. If you are running standalone this folder will be configured in conf/neo4j-server.properties and the line will look something like this:
org.neo4j.server.database.location=data/graph.db
Copy the content of that folder to the graph database folder on your other machine. I'd recommend that your databases are not running when you do this.
I believe you're looking for the dump shell command which you can use to export a database into a single Cypher create statement, you'd "dump" the database and then import it on your new machine.
Information on using the command is outlined here: Neo4j docs
A Neo4j database can be dumped and loaded using the following commands:
neo4j-admin dump --database=<database> --to=<destination-path>
neo4j-admin load --from=<archive-path> --database=<database> [--force]
Limitations
The database should be shutdown before running the dump and load commands.
https://neo4j.com/docs/operations-manual/current/tools/dump-load/
i used the above solution, but the file name was different.
in the folder of the neo4j data, look for folder called conf and inside the configuration file called neo4j.conf
inside this file you will see a line that direct to the folder that contain the data.
its called "graph.db"
replace it with the same folder from your backup of the DB that you want to clone.
Im trying to import csv files from disk with cypher commands as shown in the tutorial, but Im getting "Couldn't load the external resourse at: externalResourceFailure.
Is there any "roadmap" for importing csv in windows from files?
Thank you in advance!
take alook at SyntaxException with Neo4j LOAD command
in the question, step 3, please check if you path to the file is correct on your operating system:
the syntax for accessing a local file on windows is simply "file:c:/nosql/test/unclaimed.csv" and not file:// as might be inferred from examples on ...
You have to put the files into the import directory in neo4j.
it will work if path like this "file:///C:/myfile.csv"
The Windows and Linux file systems require different file URI schemes for streaming over HTTP. Neo4j's LOAD CSV Cypher clause makes an HTTP web request to the URI of a file and not the file system path.
For more information on file URI schemes on Windows please take a look at: http://en.wikipedia.org/wiki/File_URI_scheme#Windows_2
You can also create a folder import into your neo4j installation folder and run a cipher like this
LOAD CSV WITH HEADERS FROM "file:///yourcsvfile.csv" AS row
On mac: create a folder inside the Neo4j directory. Neo4j will install in Documents (by default)
mkdir /Users//Documents/Neo4j/default.graphdb/import
Copy your file in this location
Use it like this
USING PERIODIC COMMIT LOAD CSV WITH HEADERS FROM "file:///user_list.csv" as row create (:Users {userId: row.USER_ID });
