# Minimalistic Python Server Code
This repo contains an example of the basic, boilerplate code for a Python-based HTTP server. The server was coded on and designed to run on a Linux-based Raspberry Pi (Raspberry Pi Zero W to be specific), but can be extrapolated to run on almost any OS-based device.
The server code can be found in the [server.py](./server.py) module.
[This learing resource](https://realpython.com/python-sockets/) was used for learning as I made this.
## Making Requests
When the server is running, the client will need to make HTTP requests to the server using both the server device's local IP address **and** port number it is listening on. For example:
In the above example, HTTP requests are being made through Postman, directing the requests at the server's local IP address, followed by a colon, and the port number the server is listening on (configured in the server code).
If you instead want to simply *only* want to have to specify the server's IP address and *not* a port number, you simply need to run the server on the HTTP-dedicated port, **port 80**. But, running it on a "privileged" port, ports between 0 and 1023, will require `sudo` or `root` privileges to run and begin listening on.
## Running Server in Background After SSH Exited
When you SSH into your server and start the server `.py` script, if you run it in the background with `&` at the end of the command but then exit the SSH session, it will stop. Run this command:
```
sudo nohup python sever.py &
```
- `sudo` - will need to add this if your server is on a privileged port (port 80 for HTTP, for example).
- `nohup` - process will not be killed when you exit the SSH session (is independent of the SSH session).
- `&` - run in background.
And then, to see the process, you can run:
```
ps aux | grep python
```
`ps aux` lists background tasks. `grep python` filters to tasks with "python" in them, showing you your sever process.
To kill the process, run `kill `. So if it was process number 3407, run `kill 3407`.
