How to Install OpenTripPlanner on Linux Mint

OpenTripPlanner is an open-source routing platform that allows you to plan multi-modal trips using a variety of transportation options, including public transit, biking, and walking. In this tutorial, we will guide you through the process of installing OpenTripPlanner on Linux Mint.

Prerequisites

Before we start, make sure your system meets the following requirements:

• Linux Mint latest version
• Java Development Kit (JDK) version 8 or later
• PostgreSQL database server
• Apache Maven

Step 1: Install JDK

If you don't have JDK installed on your system, you need to install it first. Follow the below steps to install JDK:

1. Open the terminal by pressing "Ctrl+Alt+T".
2. Update the package list using the following command:

sudo apt-get update

3. Install the default-jdk package using the following command:

sudo apt-get install default-jdk

4. Verify the installation by running the following command:

java -version

You should get an output similar to the following:

openjdk version "1.8.0_292"
OpenJDK Runtime Environment (build 1.8.0_292-8u292-b10-0ubuntu1~20.04-b10)
OpenJDK 64-Bit Server VM (build 25.292-b10, mixed mode)

Step 2: Install PostgreSQL

OpenTripPlanner requires a PostgreSQL database server to store its data. You can install PostgreSQL using the following command:

sudo apt-get install postgresql

Step 3: Create a PostgreSQL Database and User

Next, we need to create a PostgreSQL database and user for OpenTripPlanner. Follow the below steps to create the database and user:

1. Switch to the PostgreSQL user account using the following command:

sudo -i -u postgres

2. Create a new user with a password using the following command:

createuser otpuser -P

You will be prompted to enter a password for the user. 3. Create a new database for OpenTripPlanner using the following command:

createdb otpdb

4. Grant all privileges on the database to the new user using the following command:

grant all privileges on database otpdb to otpuser;

5. Exit the PostgreSQL user account using the following command:

exit

Step 4: Download and Build OpenTripPlanner

1. Download the latest version of OpenTripPlanner using the following command:

wget https://repo1.maven.org/maven2/org/opentripplanner/otp/1.4.0/otp-1.4.0-shaded.jar

2. Build the project using Apache Maven:

mvn package

Step 5: Run OpenTripPlanner

1. Start OpenTripPlanner by running the following command:

java -Xmx2G -jar target/otp-1.4.0-shaded.jar --build otp --inMemory --analyst --port 8080

This command will start OpenTripPlanner on port 8080. 2. Open your web browser and go to http://localhost:8080 to access the OpenTripPlanner web application.

Congratulations! You have successfully installed and set up OpenTripPlanner on your Linux Mint system.
