How can I kill whatever process is using port 8080 so that I can vagrant up?

Question

On MacOSX, I\'m using Packer to build a Vagrant box so I need to continually bring it up and tear it down. I\'m attempting to \'vagrant up\', and receive the standard error

Answer 1

Fast and quick solution:

lsof -n -i4TCP:8080

PID is the second field. Then, kill that process:

kill -9 PID

Less fast but permanent solution

1. Go to /usr/local/bin/ (Can use command+shift+g in finder)

2. Make a file named stop. Paste the below code in it:

#!/bin/bash
touch temp.text
lsof -n -i4TCP:$1 | awk '{print $2}' > temp.text
pidToStop=`(sed '2q;d' temp.text)`
> temp.text
if [[ -n $pidToStop ]]
then
kill -9 $pidToStop
echo "Congrates!! $1 is stopped."
else
echo "Sorry nothing running on above port"
fi
rm temp.text

3. Save this file.
4. Make the file executable chmod 755 stop
5. Now, go to terminal and write stop 8888 (or any port)
