Create a folder for everything Blynk Server related

mkdir blynk_server

Make a folder for server data

mkdir ./blynk_server/server_data

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)

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

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
