If i remove the monitor and boot up, the application is not running, unless i log in with putty and execute the command manually. home/pi/.config/lxsession/LXDE-pi/autostartįor auto start when booting, but it only works when my Raspberry Pi connected to monitor during boot up. Now, that i need to run the executable file when startup without connect to any display. Xvfb-run /home/pi/System_scanning/program_Execute Xvfb-run python3 /home/pi/System_scanning/program_Execute.pyįor compiled executable command is as following: My command to run the application is as following: I tried using putty to execute in terminal and it shows Note: I had tested to execute compiled python file in autostart, but the application cant start without a display connect to. The laptop and RPi are both connected to your local network (router) by cable or WIFI. I tried to run it with putty and not connecting to any display, it works.īut if I add the instruction into autostart file in lxsession folder and boot up the Pi without any display, it unable to autostart. Direct connect network cable from laptop to RPi 2. sudo node app.js - This runs the server with administrative permissions.I need to run a executable PyQT5 python program without connect to any display on my Raspberry Pi on startup. npm install rpi-gpio - Installs the GPIO module for Raspberry Pi: Ĥ. Var express = require('express') var app = express() Īpp.get('/', function (req, res) ) ģ. nano app.js - This will create a file called "app.js" once it is open, you should paste this inside: npm install express - Installs the express module that will host a serverħ. npm init - Creates some files that NodeJS uses to manage modulesĦ. cd WebAppTest - Change directory into WebAppTestĥ. 1 USERRPIPADDRESS -pw YOURPASSWORD You will need to fill in your own information in the areas that are in all caps. mkdir WebAppTest - Make a directory colled WebAppTestĤ. cd /home/pi/Desktop - Change directory to the Desktopģ. The Raspberry Pi uses its built-in serial port to allow devices to connect to its consoleand issue commands just as if you were logged in. The Mac Terminal comes with its ownsoftware. cd / - Change directory to the root folderĢ. You will need to install terminal emulation software (Putty) if you are using Windowsand also USB drivers for the Console Lead. If you are a beginner with web development, you may want to watch some Express tutorials on YouTube to understand what is happening in the code.ġ. You could use NodeJS's HTTP module to host a server, but I like to use a NodeJS module called Express, because I find that it is easier to use. There are a few things we will need to do to get a web app running on your RPi. SSH tutorials for your OS or preferred SSH client can be found on YouTube. I recommend that you use the following guides if you have any problems with the steps above. Here are a few Linux shell commands you will need throughout this tutorial:Īpt-update - used to get latest repositories SSH into your Raspbian machine through the terminal (Mac/Linux users) or Putty (Windows users).Įverything you need to do can be done through the terminal via SSH and a few basic shell commands. Run through the basic Raspbian setup process. Contents Puttygen aka Putty Key Generator The key generation utility PuTTYgen can create various public-key cryptosystems including RivestShamirAdleman (RSA), Digital Signature Algorithm (DSA), Elliptic Curve Digital Signature Algorithm (ECDSA), and Edwards-curve Digital Signature Algorithm (EdDSA) keys. There are a few steps that you will need to complete to get your Raspberry Pi set up.
