We need to use sudo because this is a system-wide configuration file. Next, turn on the automatic upgrades by editing the file /etc/apt//10periodic. To do this, we first need to install the necessary packages. Then, we turn on Ubuntu’s unattended security upgrades. Therefore, we first upgrade all the packages in the system by running the following commands. It is important to keep our server up to date and safe over time. In this step, we will configure updates for the server. If so, follow the instructions in the above tutorial to make the swap file persistent. However, when serving large maps, a small swap file might actually be necessary, especially in low-memory Droplets. The web service does not normally require additional swap while running, so this swapfile can be removed after the setup is complete.
On low-memory Droplets, these operations may fail, which is why it is necessary to allocate a swap file. Some of the operations in this tutorial, such as building OSRM from source and the pre-processing phases, are memory intensive. Recommended 4 Gigabytes of swap, as covered in How to add swap on Ubuntu 14.04.This tutorial assumes your sudo non-root username is osrm. A sudo non-root user, which you can create by following this tutorial.Functionalities to embed OpenStreetMaps in Web pages are already provided out-of-the-box by APIs such as OpenLayers. The software that makes this possible is an open-source project called Open Source Routing Machine (OSRM), which is based on the OpenStreetMap data. How long does it take to get from point A to point B with a car, or by foot?.
The OpenStreetMap project consists of raw map data, collected and aggregated by thousands of users.
