Mac Port occupied and kill port

I have encountered a network port already occupied by other programs when I deployed the Web app on-premises, so I need to exit the process that occupies the port, we can use "terminal" to end the process of consuming a particular port.

1. Open the terminal and use the following command:

lsof-i:****

In the above command, * * * * represents the port number, we first want to know which (or which) processes occupy the port, such as you can run lsof-i:8000, see which process occupies 8000 port, and also show the process ID; We remember the process ID

2. Then use the command "Kill Process ID" to kill the process, such as:

Kill 1011

At this point we will be able to shut down the application that occupies the port.
