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

This might help

lsof -n -i4TCP:8080 

The PID is the second field in the output.

Or try:

lsof -i -P

Answer 2

I needed to run this command

sudo lsof -i :80 # checks port 8080

Then i got

COMMAND   PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
acwebseca 312 root   36u  IPv4 0x34ae935da20560c1      0t0  TCP 192.168.1.3:50585->104.25.53.12:http (ESTABLISHED)

show which service is using the PID

ps -ef 312

Then I got this

  UID   PID  PPID   C STIME   TTY           TIME CMD
    0   312    58   0  9:32PM ??         0:02.70 /opt/cisco/anyconnect/bin/acwebsecagent -console

To uninstall cisco web security agent run

sudo /opt/cisco/anyconnect/bin/websecurity_uninstall.sh

Answer 3

try netstat

netstat -vanp tcp | grep 3000

if your netstat doesn't support -p , use lsof

sudo lsof -i tcp:3000 

For Centos 7 use

netstat -vanp --tcp | grep 3000

Answer 4

Run: nmap -p 8080 localhost (Install nmap with MacPorts or Homebrew if you don't have it on your system yet)

Nmap scan report for localhost (127.0.0.1)

Host is up (0.00034s latency).

Other addresses for localhost (not scanned): ::1

PORT STATE SERVICE

8080/tcp open http-proxy

Run: ps -ef | grep http-proxy

UID PID PPID C STIME TTY TIME CMD

640 99335 88310 0 12:26pm ttys002 0:00.01 grep http-proxy"

Run: ps -ef 640 (replace 501 with your UID)

Port 8080 on mac osx is used by something installed with XCode SDK

Answer 5

To script this:

pid=$(lsof -ti tcp:8080)
if [[ $pid ]]; then
  kill -9 $pid
fi

The -t argument makes the output of lsof "terse" which means that it only returns the PID.

Answer 6

You can also use the Activity Monitor to identify and quit the process using the port.
