RNeo4j Installation Hanging, not Completing

由 和自甴很熟 提交于 2019-12-25 15:51:33
问题 I've tried installing RNeo4j package over and over, with no success - it keeps hanging, never finishing! I tried installing the packages in RStudio (with devtools::install_github("nicolewhite/RNeo4j") ), and even the base R, just to be sure. I updated my devtools to the latest, and tried again. Same thing. It would just get to ' Installing other packages curl, httr, R6, stringi ' and hang there. To confirm this wasn't an internet connection issue, I manually installed those listed packages (

How to use custom self signed certificates in Neo4j (instead of snakeoil.cert)?

问题 Recently I ran into the problem of generating a custom certificate that does not bind to 0.0.0.0 in Neo4j. It turns out that Neo4j - in contrast to the documentation - expects DER certificates for both the public and private key. I will post lessons learned in respons to this question. Rob 回答1: sudo vi /etc/neo4j/neo4j-server.properties uncomment org.neo4j.server.webserver.address=0.0.0.0 check: org.neo4j.server.webserver.https.enabled=true check: org.neo4j.server.webserver.https.port=7473

For a production Neo4j server I need to use a SSL certificate that is not self-signed. I will post lessons learned in the response below. sudo vi /etc/neo4j/neo4j-server.properties uncomment org.neo4j.server.webserver.address=0.0.0.0 check: org.neo4j.server.webserver.https.enabled=true check: org.neo4j.server.webserver.https.port=7473 change: org.neo4j.server.webserver.https.cert.location=/var/ssl/neo4j/server.crt change: org.neo4j.server.webserver.https.key.location=/var/ssl/neo4j/server.key now set up access to https note: both the private key and the certificate need to be in DER format

How to Create Nodes in RNeo4j using Vectors or Dataframes

由 风格不统一 提交于 2019-11-29 04:33:58
问题 The popular graph database Neo4j can be used within R thanks to the package/driver RNeo4j (https://github.com/nicolewhite/Rneo4j). The package author, @NicoleWhite, provides several great examples of its usage on GitHub. Unfortunately for me, the examples given by @NicoleWhite and the documentation are a bit oversimplistic, in that they manually create each graph node and its associated labels and properties , such as: mugshots = createNode(graph, "Bar", name = "Mugshots", location =

Replicate Neo4j browser auto-complete function in a cypher statement

由 馋奶兔 提交于 2019-11-29 02:41:25
I am trying to replicate the "auto-complete" functionality of the neo4j browser interface using only a cypher query. A successful implementation would mean that if the query is executed in the browser, toggling the auto-complete button would have no effect, as all "additional relationships" are specified in the query. I use the browser to prototype the queries, then use RNeo4j to implement them. Ideally, I'd like the RNeo4j result to match the browser result including auto-complete. As an example, consider the query: `MATCH p = (n:label1 {name:'tom'})-[r*2..3]-(n:label1 {name:'jerry'}) RETURN
