Howdy, welcome to my geeky corner. This blog is all about my hobbies, tech tutorials and open source projects


Raspberry Pi - Admin Panel

I've been working on a personal project about Raspberry Pi, the whole idea is simple, i needed some basic monitoring (temperature, CPU, Memory Usage) and to send commands to my Pi server, it's tedious when everytime i have to use ssh for those purposes. So I decided to make an Admin Panel, where i can check my Pi condition in real time through the web ;-)


Instructions

  • Login Page (NEW): Log-in with your username and password. If you use pi-admin for the first time, you will be redirected to the sign-up page instead

  • Status page: this page shows the status of our Pi server

  • Control: we can see the two options: Basic Mode and God Mode

  • Basic Mode: in this mode you have some basic controls like Reboot, Shutdown, Kill a running process and Peek at any directory of your PI

Example : peeking at / directory

  • God Mode: this is the place where you can truely be the god of your Pi server, you can run every command that you want here

Example: run vcgencmd measure_temp to get core temperature of BCM2835 SoC.

  • It's mobile first, so you can run this on pretty much all devices that you own ;-)

Installation

  • For this app to run, you will need Node installed, you can see how i've installed Node on my Pi server in the previous post Setting up a self-hosted blog using Raspberry Pi and Ghost

  • The whole project is available on GitHub, all you have to do is clone it from there

    git clone https://github.com/tlnguyen-com/pi-admin.git
    
  • And then install it

    cd pi-admin
    npm install
    
  • After the installation, open the main.js file in public/js/ directory using nano public/js/main.js. You should see the line var socket = io.connect('http://localhost');, change the localhost to your PI server IP address.

  • Because of the new Log-in mechanism, you will need a mongodb database, I prefer to use http://www.mongohq.com/ service instead of installing mongodb to my Pi server. So make a registration from mongohq.com, create a new database and then specify its url in the file server/config/config.js from your pi-admin directory. You will find a line db: 'mongodb://<username>:<password>@oceanic.mongohq.com:10052/pi-admin', replace the db's value with your database url.

  • You should have everything setted right, now all you have to do is start it up using npm start or node server.js or forever server.js (if you have forever installed) , whatever command you like. Or you may want to start it as a service so the admin panel will start running right after server start up. You can check how to do it from here

  • You may now see the app through the the IP address of your Pi : http://yourPiAddress:3000
