Fai

Answer 1

List process using ps -ef | grep php

Then below only works for me

kill -9 9347

which is a force kill of the process

501  9347   393   0  1:29PM ttys000    0:00.21 php artisan serve

Option 2:

If above not works, Change the default laravel serve port number if you can, like

php artisan serve --port=8088

Answer 2

The solution I found a problem we face several times in Ubuntu.

*Failed to listen on 127.0.0.1:8000 (reason: Address already in use)*

What we do, we change the port, right?

This problem can be solved also in few seconds following below steps.
1. Open Terminal
2. **sudo su**
3. **netstat -plnt**
_find the process running on port 8080_
4. **kill -9 PROCESSNUMBER**

Answer 3

best way if you 8000 port is busy or you have more one project running is run your project in new port such as 8088 or another free port.

php artisan serve --port=8088

Answer 4

When php artisan serve command given, below mentioned problem occured.

macridmi1109@Ridmis-MacBook-Pro kcnk % php artisan serve

Laravel development server started on http://localhost:8000/

[Thu Aug 6 11:31:10 2020] Failed to listen on localhost:8000 (reason: Address already in use)

Then try this line of code,

macridmi1109@Ridmis-MacBook-Pro project_laravel % ps -ef | grep php

Result will be,

501 66167 1 0 11:24am ttys002 0:00.77 /usr/bin/php -S localhost:8000 /Users/macridmi1109/Documents/Laravel/project_laravel/server.php

501 66268 64261 0 11:31am ttys002 0:00.00 grep php

Finally run the below code and, then again php artisan serve

macridmi1109@Ridmis-MacBook-Pro project_laravel % kill 66167

SOLUTION EXPLAINED BELOW

I use the command, ps -ef | grep php. After that, you will be able to find Process ID. After recognising the correct Process ID, use this command kill 66167 (kill "Process ID"). Then try php artisan serve. This worked for me.

Happy Coding

Answer 5

It is because something already running on that port and you can change the port by command itself, by running following command

php artisan serve --port 8001

Answer 6

Are there any other services running on port 8000?

You can use this command on Windows:

netstat -aon | more

or on Linux / OSX

sudo netstat -plnt

to see what services are running. Then disable the service that is running on port 8000 or use another port.
