How to kill a process running on particular port in Linux?
LinuxUnixPortKill ProcessLinux Problem Overview
I tried to close the tomcat using ./shutdown.sh
from tomcat /bin
directory. But found that the server was not closed properly. And thus I was unable to restart
My tomcat is running on port 8080
.
I want to kill the tomcat process running on 8080
. I first want to have the list of processes running on a specific port (8080) in order to select which process to kill.
Linux Solutions
Solution 1 - Linux
This fuser 8080/tcp
will print you PID of process bound on that port.
And this fuser -k 8080/tcp
will kill that process.
Works on Linux only. More universal is use of lsof -i4
(or 6 for IPv6).
Solution 2 - Linux
To list any process listening to the port 8080:
lsof -i:8080
To kill any process listening to the port 8080:
kill $(lsof -t -i:8080)
or more violently:
kill -9 $(lsof -t -i:8080)
(-9
corresponds to the SIGKILL - terminate immediately/hard kill
signal: see List of Kill Signals and What is the purpose of the -9 option in the kill command?. If no signal is specified to kill
, the TERM signal a.k.a. -15
or soft kill
is sent, which sometimes isn't enough to kill a process.).
Solution 3 - Linux
Use the command
sudo netstat -plten |grep java
used grep java
as tomcat
uses java
as their processes.
It will show the list of processes with port number and process id
tcp6 0 0 :::8080 :::* LISTEN
1000 30070621 16085/java
the number before /java
is a process id. Now use kill
command to kill the process
kill -9 16085
-9
implies the process will be killed forcefully.
Solution 4 - Linux
Option 1 A One-liner to kill only LISTEN on specific port:
kill -9 $(lsof -t -i:3000 -sTCP:LISTEN)`
Option 2 If you have npm installed you can also run
npx kill-port 3000
Solution 5 - Linux
One liner
kill -9 $(lsof -t -i tcp:8080)
Explanation here: use a combination of lsof
and kill
root@localhost:~# lsof -i tcp:8080
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 23672 sine 238u IPv6 3028222 0t0 TCP localhost:http-alt (LISTEN)
select pid and use kill
kill 23672
Solution 6 - Linux
You can use the lsof command. Let port number like here is 8090
lsof -i:8090
This command returns a list of open processes on this port.
Something like…
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
ssh 75782 eoin 5u IPv6 0x01c1c234 0t0 TCP localhost:8090 (LISTEN)
To free the port, kill the process using it(the process id is 75782)…
kill -9 75782
This one worked for me. here is the link from the original post: link
Solution 7 - Linux
If you want to kill a process running on port number 8080 then first you need to find the 8080 port process identification number(PID) and then kill it. Run the following command to find 8080 port number PID:
sudo lsof -t -i:8080
Here,
- sudo - command to ask admin privilege(user id and password).
- lsof - list of files(Also used for to list related processes)
- -t - show only process ID
- -i - show only internet connections related process
- :8080 - show only processes in this port number
So you can now easily kill your PID using following command:
sudo kill -9 <PID>
Here,
- kill - command to kill the process
- -9 - forcefully
You can use one command to to kill a process on a specific port using the following command:
sudo kill -9 $(sudo lsof -t -i:8080)
For more you can see the following link How to kill a process on a specific port on linux
Solution 8 - Linux
Best way to kill all processes on a specific port;
kill -9 $(sudo lsof -t -i:8080)
Solution 9 - Linux
This prints to stdout the process ids of everything running on <port_number>
:
fuser -n tcp <port_number>
It also prints some stuff to stderr, so:
fuser -n tcp <port_number> 2> /dev/null
We can then supply these process ids to the kill
command:
sudo kill $(fuser -n tcp <port_number> 2> /dev/null)
You could also put this in a function if you do it a lot:
function killport() {
sudo kill $(fuser -n tcp $1 2> /dev/null)
}
Solution 10 - Linux
To know the pid of service running on particular port :
netstat -tulnap | grep :*port_num*
you will get the description of that process. Now use kill or kill -9 pid. Easily killed.
e.g
netstat -ap | grep :8080
tcp6 0 0 :::8080 :::* LISTEN 1880/java
Now:
kill -9 1880
Remember to run all commands as root
Solution 11 - Linux
Get the PID of the task and kill it.
lsof -ti:8080 | xargs kill
Solution 12 - Linux
First you need to do is run (replace with your port number):
fuser -k 3000/tcp
This will release the port. After you run the above command run:
service docker restart
And your problem is resolved.
Solution 13 - Linux
try like this,
sudo fuser -n tcp -k 8080
Solution 14 - Linux
Choose the port number and apply the grep in netstat command as shown below
netstat -ap | grep :7070
Console Output
> tcp 0 0 :::7070 :::* LISTEN 3332/java
Kill the service based on PID ( Process Identification Number )
kill -9 3332
Solution 15 - Linux
-
lsof -i tcp:8000
This command lists the information about process running in port 8000 -
kill -9 [PID]
This command kills the process
Solution 16 - Linux
Linux: You can use this command if you know the port :
netstat -plten | grep LISTEN | grep 8080
AIX:
netstat -Aan | grep LISTEN | grep 8080
You then take the first column (example: f100050000b05bb8) and run the following command:
rmsock f100050000b05bb8 tcpcb
kill process.
Solution 17 - Linux
Linux: First you can find PID of this command if you know the port :
netstat -tulpn
example:-
Local Address Foreign Address State PID/Program name
:::3000 :::* LISTEN 15986/node
You then take the kill process. run the following command:
kill -9 PID
Expample: -
kill -9 15986
Solution 18 - Linux
You can know list of all ports running in system along with its details (pid, address etc.) :
netstat -tulpn
You can know details of a particular port number by providing port number in following command :
sudo netstat -lutnp | grep -w '{port_number}'
ex: sudo netstat -lutnp | grep -w '8080' Details will be provided like this :
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
if you want to kill a process using pid then : kill -9 {PID}
if you want to kill a process using port number : fuser -n tcp {port_number}
use sudo
if you are not able to access any.
Solution 19 - Linux
Run the following command to find 8080 port number PID:
> sudo lsof -t -i:8080
You can now easily kill your PID using following command:
> sudo kill -9
You can use one command to to kill a process on a specific port using the following command:
> sudo kill -9 $(sudo lsof -t -i:8000)
Solution 20 - Linux
This will kill programs running on port 80
sudo fuser -k 80/tcp
Solution 21 - Linux
kill -9 `fuser 8080/tcp|xargs -n 1`
, this commands also kills the process that listens on port 8080 with TCP connection
Solution 22 - Linux
Simply run this command. Don't forget to replace portnumber
, with your port ;)
kill -9 $(sudo lsof -t -i:portnumber)
Solution 23 - Linux
sudo apt-get install psmisc (or sudo yum install psmisc)
sudo fuser 80/tcp
Result: 80/tcp: 1858 1867 1868 1869 1871
Kill process one by one
kill -9 1858
Solution 24 - Linux
I'm working on a Yocto Linux system that has a limited set of available Linux tools. I wanted to kill the process that was using a particular port (1883).
First, to see what ports we are listening to I used the following command:
root@root:~# netstat -lt
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:hostmon 0.0.0.0:* LISTEN
tcp 0 0 localhost.localdomain:domain 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:9080 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:1883 0.0.0.0:* LISTEN
tcp 0 0 :::hostmon :::* LISTEN
tcp 0 0 localhost:domain :::* LISTEN
tcp 0 0 :::ssh :::* LISTEN
tcp 0 0 :::1883 :::* LISTEN
Next, I found the name of the process using port 1883 in the following way:
root@root:~# fuser 1883/tcp
290
root@root:~# ps | grep 290
290 mosquitt 25508 S /usr/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf
12141 root 8444 S grep 290
As we can see above, it's the program /usr/sbin/mosquitto
that's using port 1883.
Lastly, I killed the process:
root@root:~# systemctl stop mosquitto
I used systemctl
becuase in this case it was a systemd service.
Solution 25 - Linux
This is the solution for Windows:
C:\Users\Niroshan>netstat -ano|findstr "PID :8080"
Proto Local Address Foreign Address State PID
TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 18264
taskkill /pid 18264 /f
Solution 26 - Linux
Other way with Git Bash:
stopProcessByPortNumber() {
port=":${1}"
portStrLine="$(netstat -ano | findstr LISTENING | findstr $port)"
processId="$(grep -oP '(\d+)(?!.*\d)' <<< $portStrLine)"
echo $processId
taskkill -PID $processId -F
}
Solution 27 - Linux
- first check the process
netstat -lt
- check process id
fuser <port number>/tcp
- kill the process running on the port
kill <process id>
Solution 28 - Linux
to build on what @veer7 said:
if you want to know what was on the port, do this before you kill it.
$ sudo netstat -plten |grep java
tcp6 0 0 127.0.0.1:8005 :::* LISTEN 1000 906726 25296/java
tcp6 0 0 :::8009 :::* LISTEN 1000 907503 25296/java
tcp6 0 0 :::8080 :::* LISTEN 1000 907499 25296/java
$ ps 25296
PID TTY STAT TIME COMMAND
25296 ? Sl 0:16 /usr/lib/jvm/java-8-openjdk-amd64/bin/java -Dcatalina.base=/hom
Use 'ps' and the number of the process that netstat reported back
Solution 29 - Linux
In my case cent os has some issue in suggested answer. So I used following solution :
ss -tanp | grep 65432 | head -1 | grep -Po "(?<=pid=).*(?=,)" | xargs kill

How to kill process if the service on the port is not responding
timeout 1 telnet localhost 8080 2>&1 | if grep -q 'Unable'; then sudo kill -9 $(sudo lsof -t -i:8080); fi
What it does
- Start 'timeout' with one second, to make telnet exit
- ' 2>&1 | ' pipe error-message without exiting
- If error-message contains 'Unable', then run the kode to kill process locking port 8080
This can ble placed in a file and run regulary from 'sudo crontab'
Solution 31 - Linux
Just this commands work for me:
ps -aux | grep 8000
and then:
sudo kill <PID>
Solution 32 - Linux
In Windows, it will be netstat -ano | grep "8080"
and we get the following message TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 10076
WE can kill the PID using taskkill /F /PID 10076
