This mini-tutorial is inspired by this stackoverflow question
The goal is to get access to an apache tinkerpop/gremlin graph database via Python.
Prerequisites
- Java
- Python
- Gremlin-Server
- Gremlin-Console (for debugging)
To get the preqequisites you can either follow the manual or script based installation below. The script based installation is quicker - the manual installation gives you more insight and control over the installation steps.
Manual Installation
Installing Java
There are many ways to install Java and your mileage may vary.
sudo apt-get install openjdk-8-jre
java -version
openjdk version "1.8.0_222"
OpenJDK Runtime Environment (build 1.8.0_222-8u222-b10-1ubuntu1~18.04.1-b10)
OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)
Installing Python and Pip
We assume you'd like to work with python 2.7
sudo apt install python2.7
python --version
Python 2.7.15+
sudo apt install python-pip
pip --version
pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)
Installing Gremlin-Python
sudo -H pip install -r requirements.txt
Installing Gremlin Server and Console
Script based installation
The "run" installation helper script tries to automate the necessary steps
- Installation
- Gremlin-Server start
- Gremlin-Console start (for debugging)
- Python script start
The following command should get you going:
git clone https://github.com/WolfgangFahl/gremlin-python-tutorial
./run -i
./run -s
# in another console
./run -p
Help
./run -h
usage: ./run [-c|-h|-i|-p|-s|-v]
-c|--console: start console
-h|--help: show this usage
-i|--install: install prerequisites
-p|--python: start python trial code
-s|--server: start server
-v|--version: show version
Version
./run -v
apache-tinkerpop-gremlin version 3.4.3
Installation
run -i
installs
- gremlin server
- gremlin console
- gremlin python module
Gremlin-Server start
./run -s
starts the gremlin server with a default yaml-file in foreground
Gremlin-Console start (for debugging)
./run -c
starts the gremlin console
Python script start
./run -p
starts the python test script.
