Why is access to port 8000 denied?

Question

Django

after installing This package
The system started listening on port 8000, which is used by django by default.
I want to release port 8000, how can I do it now?

Answer 1

which by standard uses django

no, by default, not by standard, just run runserver on any other port.

Answer 2

It's just that someone has already occupied the port. If you are sure that there is nothing important, then just drop this process. I wrote a function like this

kill_on_port() {
    port=$(lsof -t -i:$1)
    echo "KILL PROCESS:" $port
    sudo kill -9 $port
}
alias killonport="kill_on_port [email protected]"

Although, if you have Windows, then you need something similar for Windows.
