Open Source Routing Machine (OSRM) is an open-source routing engine that calculates shortest and fastest paths on road networks. In this tutorial, we will be installing OSRM on OpenBSD.
Note: The following steps assume that you have already installed OpenBSD on your machine. If not, please install OpenBSD before proceeding.
To install OSRM on OpenBSD, you will first need to install the following dependencies:
$ doas pkg_add cmake libstxxl-dev
Next, we will download the latest version of OSRM from the official website and extract it:
$ curl -L https://github.com/Project-OSRM/osrm-backend/archive/v5.25.0.tar.gz -o osrm.tar.gz
$ tar -xzvf osrm.tar.gz
Now, we will build OSRM using the following command:
$ cd osrm-backend-5.25.0/
$ mkdir build
$ cd build
$ cmake ..
$ make
$ make install
After running the above commands, OSRM will be installed on your system.
In order to use OSRM, you will also need to download the map data for the area you will be routing in. You can download map data in multiple formats from the OpenStreetMap website. For this tutorial, we will download map data in the pbf format:
$ curl -L http://download.geofabrik.de/europe/germany/berlin-latest.osm.pbf -o berlin-latest.osm.pbf
We will now preprocess the map data using the following command:
$ osrm-extract berlin-latest.osm.pbf -p ../profiles/car.lua
$ osrm-partition berlin-latest.osrm
$ osrm-customize berlin-latest.osrm
The above commands will generate a new file named berlin-latest.osrm.
Finally, we will start the OSRM server using the following command:
$ osrm-routed berlin-latest.osrm
You will now be able to access the OSRM server by visiting http://localhost:5000/ in your web browser.
That's it! You have successfully installed OSRM on OpenBSD and can now use it to calculate the shortest and fastest paths on road networks.
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!
