daemonize | Command line utility to run a program as a Unix daemon | Command Line Interface library

I have deployed to azure a create-react-app that has a server.js file for dynamically generating meta tags.

The stack is Node 16 on Linux

In my startup command I have pm2 start /home/site/wwwroot/server.js --no-daemon

My server.js is as follows

my reference:
https://docs.djangoproject.com/en/4.0/howto/deployment/wsgi/uwsgi/

my project name:
'mysite'

my directories:

I create 'uwsgi.ini'.

then, I written in ini file.

I have a Sinatra app (app.rb) that resides within within /var/www/example. My setup is nginx, thin, and sinatra.

I have both nginx and thin up and running but when I navigate to my site, I get a 404 from nginx. I assume that the server block config is wrong. I've tried pointing root to /var/www/example/ instead of public but that makes no difference. I don't think the request makes it as far as the sinatra app.

What am I doing wrong?

Server block:

I am trying to make an image that uses the MySQL image as its base and I want to create a database (and some other stuff) once I know the server is up. I have a bootstrap script as my entrypoint in which the first thing I do is run mysql image's entrypoint script in background as ./entrypoint.sh mysqld &.

Currently, what I do after this is start a loop with some sleep that uses mysqladmin --ping to check if the server is up. Once its up I start my other commands and start creating the database I want.

This works fine when mysql is already initialized (i.e. not the first time the container is started/entrypoint.sh is executed). But on the first run the image seems to create a temporary mysql server (mysqld --daemonize --skip-networking --default-time-zone=SYSTEM --socket="${SOCKET}" - from the entrypoint script), run some commands and then stop that server. Post that it starts the actual server. The problem I am facing is that the mysqladmin ping command actually reacts with a success to the temporary server itself and so my script tries to create the database which fails.

I've read many answers here that say to run the ping command (that I am using) to check if server is up, but none that I saw mention anything about this temporary server or how to detect if it is a temporary one.

Any clues as to how I can detect this ? Or if there is anything better I can do at any part of the flow I have mentioned above ?

I do have one hacky solution in mind right now. One involves updating the entrypoint script to use a different from default socket file for the temporary server, which I can then use to see if the server running is temporary or not, but I'd rather not resort to this if a standard solution exists.

Thanks!

I am quite new to Puppet and I am having some problems with the Puppet Config for one of our hosts running Puppet Agent. We are using Ubuntu 20.04 and Puppet CE 7.12.1 on all systems.

On our Puppet Server (Hostname: puppet), I am trying to write the Puppet config for our host eb-web (which is running a Puppet Agent). I would like to configure UFW (Uncomplicated Firewall) (https://help.ubuntu.com/community/UFW) on eb-web using the Puppet Module kogitoapp/ufw version 1.0.3 (https://forge.puppet.com/modules/kogitoapp/ufw) to allow through HTTP traffic.

Our Puppet Server is configured to use Hiera to hold our facts. So far I have created the following configuration files: File: /etc/puppetlabs/code/environments/production/hiera.yaml

I'm trying to deploy my first django app by following these steps. The problem I have is that, for some reason, running uwsgi --emperor venv/vassals/ --uid www-data --gid www-data after activating my venv just seems to delete the .sock file in my root dir. I assume this is causing the problem because looking at the nginx logs at /var/log/nginx/error.log suggest so:

I've written a Pi Hardware Interface Server (phis) that uses http protocol to control the hardware connected to my Raspberry Pi (relays, analog measurements, etc). It processes simple requests and responds with plain text. It has been working flawlessly for years and I have written extensive browser-based interfaces to the system. Here's the basic structure:
