How to Install DeviceHive on Elementary OS Latest

DeviceHive is an open-source IoT platform that provides a framework for building scalable and secure smart devices. In this tutorial, we will guide you through the process of installing DeviceHive on your Elementary OS Latest operating system.

Prerequisites

Before we begin, please make sure you have the following prerequisites installed on your system:

• Elementary OS Latest
• Java 8 or later
• Git

You can check if Java and Git are installed on your system by running the following commands:

java -version
git --version

Step 1: Install PostgreSQL

DeviceHive requires a PostgreSQL database, so we need to install it first:

1. Open the terminal.
2. Update the package list: sudo apt-get update
3. Install PostgreSQL: sudo apt-get install postgresql postgresql-contrib
4. Verify the installation: sudo systemctl status postgresql

Step 2: Install Apache Maven

DeviceHive requires Apache Maven to build the source code. To install it, run the following commands:

1. Open the terminal.
2. Download the latest version of Apache Maven: wget https://apache.osuosl.org/maven/maven-3/3.8.2/binaries/apache-maven-3.8.2-bin.tar.gz
3. Extract the downloaded package: tar -xzvf apache-maven-3.8.2-bin.tar.gz
4. Rename the extracted folder: sudo mv apache-maven-3.8.2 /opt/maven
5. Set the environmental variables: sudo nano /etc/environment
6. Add the following lines at the end of the file:

MAVEN_HOME=/opt/maven
PATH=${MAVEN_HOME}/bin:${PATH}

7. Save and close the file.
8. Reload the environmental variables: source /etc/environment

Step 3: Install DeviceHive

Now that we have installed all the prerequisites, let's proceed with installing DeviceHive:

1. Open the terminal.
2. Clone DeviceHive from Github: git clone https://github.com/devicehive/devicehive-java-server.git
3. Change to the devicehive-java-server directory: cd devicehive-java-server
4. Build the source code: mvn clean package -DskipTests=true
5. Wait until the build is complete.
6. Create a DeviceHive database and user:

sudo -u postgres psql
CREATE DATABASE devicehive;
CREATE USER devicehive WITH PASSWORD 'devicehive';
GRANT ALL PRIVILEGES ON DATABASE devicehive TO devicehive;
\q

7. Edit the configuration file: nano server/src/main/resources/dh-application.properties
8. Update the following lines with your PostgreSQL database details:

hibernate.connection.url=jdbc:postgresql://localhost:5432/devicehive
hibernate.connection.username=devicehive
hibernate.connection.password=devicehive

9. Save and close the file.
10. Start the DeviceHive server: java -jar server/target/server.jar

Congratulations! You have successfully installed DeviceHive on your Elementary OS Latest operating system. To access the DeviceHive web interface, open your web browser and go to http://localhost:8080.
