• Downloads and initializes the Blynk Server
• Installs the server as a systemd service if you so choose

Quick Install

1. Clone this repo

git clone https://github.com/librarysteve/installblynkpi.git

2. Run the installer script

cd ./installblynkpi

sudo chmod +x ./install.sh

sudo ./install.sh

3. Answer "Yes" if you would like it to start on boot

Manual Install

1. Update, upgrade, and install openjdk 8

sudo apt-get update && sudo apt-get -y upgrade

sudo apt-get install -y openjdk-8-jdk

2. Download a copy of the latest blynk server from The Blynk Server Repo or via wget

wget https://github.com/blynkkk/blynk-server/releases/download/v0.41.10/server-0.41.10-java8.jar

3. Create a folder for everything Blynk Server related

mkdir blynk_server

4. Make a folder for server data

mkdir ./blynk_server/server_data

5. Create a shell script to start the server something like:

#!/bin/bash
$(java -jar /home/pi/blynk_server/server-0.41.10-java8.jar -dataFolder /home/pi/blynk_server/data_folder)

6. Create a service "Unit File" so the server will start on boot using systemd

sudo nano /etc/systemd/system/blynk.service

Example Unit File:

[Unit]
Description=Blynk IoT Server
After=network.target

[Service]
ExecStart=/home/pi/blynk_server/start_blynk_server.sh
WorkingDirectory=/home/pi/blynk_server
StandardOutput=inherit
StandardError=inherit
Restart=Always
User=pi

[Install]
WantedBy=multi-user.target

7. Enable the service with systemctl First start the service

sudo systemctl start blynk.service

Then enable

sudo systemctl enable blynk.service

Then check to see if it is running

sudo systemctl status blynk

if you see an "active" message (usually in green) you're good to go
