Open Source Routing Machine (OSRM) is a high-performance routing engine designed for car, bike, and pedestrian routing. It allows you to compute shortest paths in a network of roads with the help of OpenStreetMap data. In this tutorial, we will show you how to install OSRM on Alpine Linux.
Before we begin, please ensure that you have the following:
The first and most important step is to install the dependencies needed by OSRM. Open your terminal and run the following command:
sudo apk add build-base git cmake libstdc++ libxml2-dev libzip-dev bzip2-dev zlib-dev
This command will install the necessary dependencies on your machine.
Next, we need to clone the OSRM repository from GitHub. Run the following command to clone the repository:
git clone https://github.com/Project-OSRM/osrm-backend.git
This command will create a new directory named osrm-backend.
To build and install OSRM, navigate to the osrm-backend directory and run the following commands:
mkdir build
cd build
cmake ..
make
sudo make install
This will build and install OSRM on your machine.
Now that we have installed OSRM on our machine, we need to download and prepare OpenStreetMap (OSM) data.
OSRM requires the data to be in .osm.pbf format. You can download OSM data from Geofabrik.
Once you have downloaded the data, navigate to the osrm-backend directory and run the following command:
osrm-extract data.osm.pbf -p profile.lua
This will extract the data and prepare it for OSRM.
Finally, we need to generate the OSRM graph. To do this, run the following command:
osrm-contract data.osrm
This will generate the OSRM graph that we can use to run queries against.
Congratulations! You have successfully installed OSRM on Alpine Linux and prepared the OSM data to generate the OSRM graph. You can now use OSRM to compute shortest paths in a network of roads.
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!
