It seems that ports are being used already. Have you tried restarting your pc?

3

Yeah I tried that but didnot work any solution for it.
I also tried to server next port with
bench serve --port portnumber

still getting error while setup .
It shows "There is error " in message.

Any solution please.

instead of bench serv ,try to kill the ports 11000,12000,13000 using

kill $(lsof -t -i:{PORT_NUMBER})
ex.

kill $(lsof -t -i:11000)

Thank you for you support.
But unfortunately i cannot able to overcome from issue.
This command doesn’t kill the port instead suggest for the commands.
seeking for more support please.

run with sudo

ex. sudo kill $(lsof -t -i:8080)

7

I got this.
Still same error while running bench.

swift@ubuntu:~/frappe-bench$ sudo kill $(lsof -t -i:11000)

Usage:
kill [options] […]

Options:
[…] send signal to every listed
-, -s, --signal
specify the to be sent
-l, --list=[] list all signal names, or convert one to a name
-L, --table list all signal names in a nice table

-h, --help display this help and exit
-V, --version output version information and exit

For more details see kill(1).

kill -9 $(lsof -t -i:11000)
the above command works but only if the port is in use it will kills hence first try bench start if still it shows the same error
i.e.,
listening socket 127.0.0.1:13000: bind: Address already in use

9

127.0.0.1:12000: bind: Address already in use

Try
$ ps aux | grep redis
you will get
redis 3044 0.0 0.0 37000 8780 ? Ssl 14:59 0:00 /usr/bin/redis-server *:6379

$ sudo kill -9 3044
$ sudo service redis-server restart
