How to Install Neo4j Server on Centos/RHEL

5/15/2015

Run the following commands to download and import neotechnology's public gpg key into the rpm keyring

cd /tmp
wget http://debian.neo4j.org/neotechnology.gpg.key
sudo rpm --import neotechnology.gpg.key

Create the neo4j repo file using you editor of choice and add it to the yum repos definition directory. Add the following lines to the neo4j.repo file

[neo4j]
name=Neo4j Yum Repo
baseurl=http://yum.neo4j.org
enabled=1
gpgcheck=1

nano neo4j.repo
sudo cp neo4j.repo /etc/yum.repos.d/

Finally run the command to install neo4j
sudo yum install neo4j

Here are some things to note with the install:
  • - An java jdk (openjdk) is installed and configured for you even if you already have one on the server.
  • - The neo4j binaries are installed to /usr/share/neo4j
  • - The neo4j properties files are installed to /etc/neo4j
  • - The default/initial database location is /var/lib/neo4j
  • - Neo4j is installed as a service in the stopped state. You can start it by running sudo service neo4j start. By default, the neo4j instance is only accessible via http://localhost:7474/. If you want to enable outside access, you need to uncomment the line in the neo4j-server.properties file: #org.neo4j.server.webserver.address=0.0.0.0 and restart the server.
