Raspberry PI 3B+ Buster, Server not working

miraclecontrols · May 16, 2020, 6:29am

Raspberry Pi 3B+ Server localhost:3030 does not work after install Anvil App Server Jar.

Failed to start built-in Postgres database: java.lang.IllegalStateException: Process failed
More logs are available in .anvil-data/postgres.log.
Some common causes of this problem:

Are you launching this server as ‘root’ on a UNIX system?
Postgres will not run as root; try launching the server as an ordinary user.
Are you running this server on an unusual architecture or OS? (Linux/arm)

tail .anvil-data/postgres.log.

initdb: cannot be run as root
Please log in (using, e.g., “su”) as the (unprivileged) user that will
own the server process.

What could be the solution to this?

# Running Anvil apps locally

You can export any Anvil app from the Anvil Editor and run it on your computer using the open-source [Anvil App Server](https://github.com/anvil-works/anvil-runtime). 

You can also **build and deploy your apps in Anvil's cloud** -- by far the easiest way to build a web app. Build your app using our [online IDE](https://anvil.works), complete with drag-and-drop UI designer and autocomplete -- then [click one button](https://anvil.works/docs/deployment), and it's live on the web!

Follow this how-to guide to export an Anvil app from the online IDE and run it on your own machine.

All you need to do to run your app locally is:

1. Install the Anvil App Server
2. [Clone an Anvil app onto your local machine with git](https://anvil.works/docs/version-control/git)
3. Launch your app

## Set up your environment

### Dependencies

You will need to install the **Java virtual machine**. On Debian-based Linux systems (like Ubuntu and Raspbian), you can do:

I follow this tutorial above and works great … you try

Yes it worked thank you. Needed Java virtual machine. Do you know how to run it as a background service?

I create a bash file and it will run everytime i start RaspberryPi … easy

I am a bit new to yaml. Can you please give me a link or bash script to get me started. Tried web search but did not succeed.

#!/bin/bash

cd /home/pi
. env/bin/activate
echo “DONE”
anvil-app-server --app your_app_name

this is what i have in my bash file.
you only need to create an empty file, inside you put that, save … run … and its done

Of course, you need to clone your app from git hub before you do that, to /home/pi
And already create the environment env as you see in the tutorial

you try

##Somehow bash did not work for me so I adopted systemd method.

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

##and inserted the following in the file:

[Unit]
Description=camera service
After=network.target

[Service]
ExecStart=anvil-app-server --app <my_app_name_here>
WorkingDirectory=/home/pi/
StandardOutput=inherit
StandardError=inherit
Restart=always
User=pi

[Install]
WantedBy=multi-user.target

##ctrl+x then y then enter to save
##and it worked after doing this on terminal

sudo systemctl enable camera.service
sudo systemctl start camera.service
sudo systemctl daemon-reload

Perfect. Thank you for your assistance
