How to Install GraphHopper on Fedora Server

This tutorial will guide you through the process of installing GraphHopper on the latest version of Fedora Server. GraphHopper is a powerful, open-source routing engine that can be used for various applications such as GPS navigation, logistics, and vehicle routing.

Prerequisites

Before we begin, ensure that your system meets the following requirements:

• A running instance of Fedora Server on your device.
• A user account with sudo privileges.

Step 1: Install Java

GraphHopper requires Java 8 or later to run. Furthermore, Fedora Server doesn't come with Java installed by default, so you'll have to install it yourself. You can use the following command to install OpenJDK on your machine:

sudo dnf install java-1.8.0-openjdk

Step 2: Download GraphHopper

1. Navigate to the GraphHopper download page using your web browser by going to this link: https://graphhopper.com/#getstarted.
2. Click on the "Download" button located on the page.
3. Select the "GraphHopper" option from the drop-down list that appears.
4. Click on the "Download" button beside your preferred format (we'll use ".tar.gz" in this guide).
5. Open your terminal to download the package with the following command:

wget https://oss.sonatype.org/content/repositories/releases/com/graphhopper/graphhopper-web/3.3/graphhopper-web-3.3-bin.tar.gz 

Step 3: Install GraphHopper

1. Extract the downloaded package into a folder:

tar xzf graphhopper-web-3.3-bin.tar.gz

2. Change your working directory to the graphhopper directory:

cd graphhopper-web-3.3/

3. Set up the OSM data file from the source you want. We’ll use the Berlin OpenStreetMap file:

wget http://download.geofabrik.de/europe/germany/berlin-latest.osm.pbf

4. Run GraphHopper:

./graphhopper.sh web berlin-latest.osm.pbf

5. Wait for GraphHopper to complete the initialization process. A message similar to the one below should appear.

2018-05-22 11:11:54.884 [main] INFO  com.graphhopper.http.GHServer - Started server at HTTP :8989

6. Use your browser and open http://localhost:8989, and you should see the GraphHopper web interface.

You've successfully installed GraphHopper on Fedora Server, and can use it for various applications!

Conclusion

In this tutorial, we've guided you through the installation of GraphHopper on Fedora Server, step by step.
