![]() I have the idea that I cannot get the traccar server running one way or the other.Īt least when I try the traccar Port Check to port 8082 I get the message that the port is closed. I have done the port forwarding steps in the router to the IP address of the Raspberry. I have tried but no connection is established to the traccar server. I have tried with the downloads traccar-linux-arm-4.12 and with traccar-linux-64-4.12.Īfter: "sudo systemctl start traccar" nothing happens. The linux installed on the RPI is Ubuntu Desktop 20.10 64b I have a Raspberry Pi 4, 8Gb with a 32 Gb sd card. Up till inclusive the steps of extracting the traccar file and the creation of the /opt/traccar/. However considering the power consumption of my old PC I have bought a Raspberry Pi 4 and installed Linux and traccar on it. I installed linux and downloaded traccar and everything works fine. Is used by some Java applications to determine the Java installation location.I have installed the traccar server on an old PC. Enter the number of the version you want set as the default and press Enter. You will be presented with a list of all installed Java versions. Press to keep the current choice, or type selection number: ![]() * 0 /usr/lib/jvm/java-11-openjdk-armhf/bin/java 1111 auto modeġ /usr/lib/jvm/java-11-openjdk-armhf/bin/java 1111 manual modeĢ /usr/lib/jvm/java-8-openjdk-armhf/jre/bin/java 1081 manual mode The output will look something like below: There are 2 choices for the alternative java (providing /usr/bin/java). ![]() To change the default version, use the update-alternatives tool: sudo update-alternatives -config java If you have multiple Java versions installed on your Pi, run the java -version command to check the default version: java -version OpenJDK Client VM (build 25.212-b01, mixed mode) Set the Default Version # The output should look something like this: openjdk version "1.8.0_212" Verify the installation by printing the Java version Although I doubt a bit the accuracy of GPS reception in a dense city and my original plan included something like detecting nearby wifi networks but that type of location services is paid and becomes a bit expensive once you start polling the server every few minutes. If your application requires Java 8, install it by typing: sudo apt update sudo apt install openjdk-8-jdk Sounds great I always wanted to do something like this. Subscribe to the project news and updates. The previous Java LTS version 8 is still supported and widely used. Traccar is a free and open source modern GPS tracking system. That’s it! You have successfully installed Java on your Pi, and you can start using it. OpenJDK Server VM (build 11.0.5+10-post-Raspbian-1deb10u1, mixed mode) OpenJDK Runtime Environment (build 11.0.5+10-post-Raspbian-1deb10u1) The output should look something like this: openjdk version "11.0.5" Once the installation is complete, verify it by checking the Java version: java -version Run the following commands to install the OpenJDK 11 JDK on your Raspberry Pi: sudo apt update sudo apt install default-jdk OpenJDK 11 is the default Java development and runtime in the latest Raspbian OS, which is based on Debian 10, Buster. Some Java-based applications may require a specific version of Java, so you should consult the application documentation. If you are not sure which Java package to install, the general recommendation is to stick to the default OpenJDK (JDK 11) version. JDK consist of JRE and development/debugging tools and libraries necessary to build Java applications. JRE includes the Java virtual machine (JVM), classes, and binaries that allow you to run Java programs. The standard Raspbian repositories include two different Java packages, Java Runtime Environment (JRE) and Java Development Kit (JDK). ![]() This guide explains how to install Java (OpenJDK) on Raspberry Pi with the latest Raspbian OS running on it. That permits only non-commercial use, such as personal or development use. Oracle Java has a few additional commercial features and a license OpenJDK is an open-source implementation of the Java Platform. There are two different implementations of Java, Oracle Java and OpenJDK. Java is one of the most popular programming languages used to build different kinds of applications and systems.
