How to install OpenTripPlanner on nixOS latest

OpenTripPlanner is a travel itinerary planning system that is open source and designed for multi-modal public transit. In this tutorial, we'll be walking you through the steps to install OpenTripPlanner on nixOS latest.

Prerequisites

Before we dive into the installation process, ensure you have the following requirements:

  • nixOS latest.
  • Stable internet connection.

Step 1: Install Java Development Kit (JDK)

OpenTripPlanner requires Java Development Kit (JDK) to run. For this, we’ll be using the stable release of AdoptOpenJDK.

Run the following command on the terminal: 

$ nix-env -iA nixos.adoptopenjdk

The installation might take some time to complete.

After the installation is complete, check if the installation was successful by running the following command:

$ java -version

You should see output similar to the following:

openjdk version "11.0.12" 2021-07-20
OpenJDK 64-Bit Server VM (build 11.0.12+7, mixed mode)

Step 2: Install OpenTripPlanner

Now, we can begin the installation process of OpenTripPlanner.

We'll be using the Nix package manager to install OpenTripPlanner. You can get the OpenTripPlanner package by running the following command:

$ nix-env -iA nixos.opentripplanner

The installation might take some time to complete depending on your internet speed.

After installation is complete, you can check if the installation was successful by running the following command:

$ otp --version

You should get output similar to the following:

OpenTripPlanner version 1.3.0

If you get a different output, the installation might have been unsuccessful, and you will need to check your installation again.

Step 4: Run OpenTripPlanner

Now that OpenTripPlanner is installed, you can start up the server by running the following command:

$ otp --build /path/to/data

This process might take some time, especially if the data files are large.

After the process is complete, you can run the following command to start the OpenTripPlanner server:

$ otp --server

You should see a message like the following indicating success:

INFO: Listening on http://localhost:8080/

With the server running, you can open your browser and navigate to http://localhost:8080. Here, you can test the installation by searching for a route on the map.
