How to install GraphHopper on NetBSD

GraphHopper is an open-source routing engine that uses OpenStreetMap data to provide routing capabilities. In this tutorial, we will guide you through the process of installing GraphHopper on NetBSD.

Prerequisites

Before we start with the installation process, make sure that you have the following prerequisites installed on your NetBSD system:

• NetBSD version 8.0 or higher
• OpenJDK 8 or higher

Step 1: Download GraphHopper

Go to the GraphHopper website (https://graphhopper.com/) and download the latest version of GraphHopper. Alternatively, you can use the following command to download GraphHopper on your NetBSD system:

$ fetch https://graphhopper.com/public/releases/graphhopper-web-3.2.0-bin.zip

Note: Replace the filename with the latest version available.

Step 2: Unzip GraphHopper

After downloading GraphHopper, unzip it using the following command:

$ unzip graphhopper-web-3.2.0-bin.zip

Step 3: Configure GraphHopper

Next, we need to configure GraphHopper. To do this, navigate to the graphhopper-web-3.2.0 directory and create a config.yml file:

$ cd graphhopper-web-3.2.0
$ nano config.yml

Copy and paste the following configuration into the config.yml file:

graphhopper:
  datareader.file: /path/to/your/map.osm.pbf
  graph.flag_encoders: car
  preparation:
    minimizer: compact
  routing:
    ch:
      weighting: fastest
    lm:
      enabled: false
  plugins:
  - openweathermap

datareader:
  osm:
    parse_osm: false
    skip_invalid_edges: true
  elevation_provider: cgiar
  graph_cache:
    enable: false

web:
  bind_host: localhost
  port: 8989

Note: Change the datareader.file value to the path of your OpenStreetMap data file.

Step 4: Start GraphHopper

Finally, we can start GraphHopper using the following command:

$ java -jar *.jar server config.yml

GraphHopper should now be running and available at http://localhost:8989/.

Congratulations! You have successfully installed GraphHopper on NetBSD.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
