# Neo4J
|
|
|
|
Human Connection is a social network. Using a graph based database which can
|
|
model nodes and edges natively - a network - feels like an obvious choice. We
|
|
decided to use [Neo4j](https://neo4j.com/), the currently most used graph
|
|
database available. The community edition of Neo4J is Free and Open Source and
|
|
we try our best to keep our application compatible with the community edition
|
|
only.
|
|
|
|
## Installation with Docker
|
|
|
|
Run:
|
|
|
|
```bash
|
|
docker-compose up
|
|
```
|
|
|
|
You can access Neo4J through [http://localhost:7474/](http://localhost:7474/)
|
|
for an interactive cypher shell and a visualization of the graph.
|
|
|
|
|
|
## Installation without Docker
|
|
|
|
Install the community edition of [Neo4j](https://neo4j.com/) along with the plugin
|
|
[Apoc](https://github.com/neo4j-contrib/neo4j-apoc-procedures) on your system.
|
|
|
|
To do so, go to [releases](https://neo4j.com/download-center/#releases), choose
|
|
"Community Server", download the installation files for you operation system
|
|
and unpack the files.
|
|
|
|
Download [Neo4j Apoc](https://github.com/neo4j-contrib/neo4j-apoc-procedures/releases)
|
|
and drop the `.jar` file into the `plugins` folder of the just extracted Neo4j-Server.
|
|
|
|
Then make sure to allow Apoc procedures by adding the following line to your Neo4j configuration \(`conf/neo4j.conf`\):
|
|
|
|
```
|
|
dbms.security.procedures.unrestricted=apoc.*
|
|
```
|
|
|
|
### Alternatives
|
|
|
|
You can download [Neo4j Desktop](https://neo4j.com/download/) and run locally
|
|
for development, spin up a
|
|
[hosted Neo4j Sandbox instance](https://neo4j.com/download/), run Neo4j in one
|
|
of the [many cloud options](https://neo4j.com/developer/guide-cloud-deployment/),
|
|
[spin up Neo4j in a Docker container](https://neo4j.com/developer/docker/),
|
|
on Archlinux you can install [neo4j-community from AUR](https://aur.archlinux.org/packages/neo4j-community/)
|
|

|
|
Just be sure to update the Neo4j connection string and credentials accordingly
