Learning Neo4j 3.x - Second Edition

By: Jerome Baton

Overview of this book

Neo4j is a graph database that allows traversing huge amounts of data with ease. This book aims at quickly getting you started with the popular graph database Neo4j. Starting with a brief introduction to graph theory, this book will show you the advantages of using graph databases along with data modeling techniques for graph databases. You'll gain practical hands-on experience with commonly used and lesser known features for updating graph store with Neo4j's Cypher query language. Furthermore, you'll also learn to create awesome procedures using APOC and extend Neo4j's functionality, enabling integration, algorithmic analysis, and other advanced spatial operation capabilities on data. Through the course of the book you will come across implementation examples on the latest updates in Neo4j, such as in-graph indexes, scaling, performance improvements, visualization, data refactoring techniques, security enhancements, and much more. By the end of the book, you'll have gained the skills to design and implement modern spatial applications, from graphing data to unraveling business capabilities with the help of real-world use cases.

Preface

Reset password


Even on a development machine that I use everyday, I may have forgotten the clever password I set up for the user Neo4j, as I have several versions installed on my machine.

The solution is to stop your server, then change the directory to the data/dbms subfolder, and remove the file named auth.

Check for other hosts

To know what hosts are running on your local network, with SSH access enabled, I offer you this little script:

#!/bin/bash

port=22
for ordi in `nmap -sn 192.168.0.1-100 /25 | egrep "scan report" | awk '{print $5}'`
do 
   echo Found IP $ordi on network.
   echo --------------------------------------
done
echo Now trying them for port $port , sorry for the timeout on successful connections
echo
for ordi in `nmap -sn 192.168.0.1-100 /25 | egrep "scan report" | awk '{print $5}'`
do
   echo Trying $ordi on port $port
   cat < /dev/tcp/$ordi/$port
   echo --------------------------------------
done

You may need to adapt this to change the IP range. Unix super users...
