This is a guide for standing up a quick server using Yum on AWS Linux.
Other options for getting a server running are:

  1. Manual download and install, instructions can be found here
  2. There is a cloud formation template that Neo4J provide here

Prerequisites

  • AWS Linux EC2 instance. I used a T2.Medium but check here for suggested sizing.
  • Security Group setup to allow incoming traffic on port 22 and 7474.

Install Instructions

SSH onto the server the run the following commands

sudo su
cd /tmp
wget http://debian.neo4j.org/neotechnology.gpg.key
rpm --import neotechnology.gpg.key
cat <<EOF> /etc/yum.repos.d/neo4j.repo
[neo4j]
name=Neo4j Yum Repo
baseurl=http://yum.neo4j.org
enabled=1
gpgcheck=1
EOF

If you wish to install a certain version of Neo4J then run a command like the one below replace the version number as required

yum -y install neo4j-2.3.2

If you just want the latest version run the alternative below command instead

yum -y install neo4j

edit /etc/neo4j/neo4j-server.properties ( This is called neo4j.conf in version 3)
Remove the # from the line below in the file

#org.neo4j.server.webserver.address=0.0.0.0

Restart the service

service neo4j restart

To have this run as a service run these commands

chkconfig --add neo4j
chkconfig neo4j on

Log into Neo4J on http://<EC2 IP Address>:7474
The default username and password are neo4j/neo4j you will be prompted to change the password after the first login.

    Hi, Ben,
    when I tried to restart neo4j server: I got error
    # service neo4j restart
    ERROR! Neo4j cannot be started using java version 1.7.0_181.
    * Please use Oracle(R) Java(TM) 8, OpenJDK(TM) or IBM J9 to run Neo4j.
    Any issue with JAVA setting?
    or do you have the new version of the scenario?
    thanks,
    Hank

    Thanks Travis
    Always good to keep these repository details up to date, even on old install instructions.
