Unable to start laravel development server on linux

问题

I am using laravel 5 for my project and everything has been working fine but recently I am facing this problem which I done understand.

devboy@devboy-hp ~/sonel_ims_project/ims_eneo $ php artisan serve
Laravel development server started on http://localhost:8000/
[Fri Nov 13 12:00:56 2015] Failed to listen on localhost:8000 (reason: Address already in use)

I have tried devboy@devboy-hp ~ $ sudo netstat -plnt and get

Then I change port like so php artisan serve --port="8888" but get similar error like below after a while:

Laravel development server started on http://localhost:8888/
[Fri Nov 13 12:01:02 2015] Failed to listen on localhost:8888 (reason: Address already in use)

The first time it happened, it was java using port 8000, so I killed the process and started the server and it worked. Upon stopping and restarting, I get the same error. What could be the problem (as I said everything has been working fine except now and I have not done any major update)?

回答1:

Your previous deployment in your local is already running that's why you can't run php artisan serve. You can solve your issue by following this command in your terminal:

ps -ef | grep php you'll see this list:

gujarat 6690 3500 0 05:55 pts/1 00:00:00 php artisan serve
gujarat 6694 6690 0 05:55 pts/1 00:00:00 sh -c '/usr/bin/php5' -S localhost:8000 '/home/gujarat/WebDevelopment/quickstart-basic'/server.php
gujarat 6695 6694 0 05:55 pts/1 00:00:00 /usr/bin/php5 -S localhost:8000 /home/gujarat/WebDevelopment/quickstart-basic/server.php
gujarat 7436 3500 0 06:26 pts/1 00:00:00 grep --color=auto php
Now kill it using: sudo kill 6690 if still exist then use this sudo kill -9 6690 you'll see this result:

[1]+ Killed php artisan serve

Now you can serve your local using php artisan serve again

回答2:

This is exactly what I did for the problem.

I exit PHPStorm
sudo netstat -plnt
kill 7563 (Process using port 8888)
kill 6931 (Process using port 8000)
sudo /opt/lampp/lampp restart (Restart my server altogther)
php artisan serve
Launch PhpStorm

Now everything is working fine. What caused the problem anyway?

回答3:

please restart apache server

sudo apache restart

And once again run your project in another port

php artisan serve --port=2020

回答4:

Using lsof, you can see what is listening on the port.

sudo lsof -i :80

Change the 80 to whichever port you're interested. You need to be root or sudo.

回答5:

Well the problem might be it didnt stop the expected way previously eg via CTRL+C so what you can do is to check for running php processes and kill them 1 by 1.

i) Run ps -A from the terminal then identify the php process ids (most of the times they are two)

ii) Run sudo kill -9 pid# corresponding to the php pids.

iii) Run php artisan serve and it will work.

Run this comment

sudo netstat -plnt

The output will show like this

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name 
tcp       14      0 127.0.0.1:8000          0.0.0.0:*               LISTEN      3648/php7.3

Then kill the port:8000 using this comment

 kill -9 3648
