I’m using django-gunicorn-nginx setup by following this tutorial http://ijcdigital.com/blog/django-gunicorn-and-nginx-setup/ Upto nginx setup, it is working. Then I installed supervisor, configured it and then I reboot my server and checked, it shows 502 bad gateway. I’m using Ubuntu 12.04 LTS
[program: qlimp] directory = /home/nirmal/project/qlimp/qlimp.sh user = nirmal command = /home/nirmal/project/qlimp/qlimp.sh stdout_logfile = /path/to/supervisor/log/file/logfile.log stderr_logfile = /path/to/supervisor/log/file/error-logfile.log
Then I restarted supervisor and I run this command
$ supervisorctl start qlimp and I’m getting this error
unix:///var/run/supervisor.sock no such file
Is there any problem in my supervisor setup?
That there is no socket file probably means that supervisor isn’t running. A reason that it isn’t running might be that your qlimp.conf file has some sort of error in it. If you do a
sudo service supervisor start
you can see whether or not this is the case. If supervisor is already running, it will say. And if it is catching an error, it will usually give you a more helpful error message than supervisorctl.
I have met the same issue as you and after several times, here comes the solution:
First remove the apt-get supervisor version:
sudo apt-get remove supervisor
Kill the backend supervisor process:
sudo ps -ef | grep supervisor
Then get the newest version(apt-get version was 3.0a8):
sudo easy_install(pip install) supervisor==3.0b2
Echo the config file(root premission):
echo_supervisord_conf > /etc/supervisord.conf
Anything has been done! Have fun!
cd /etc/supervisor sudo supervisord sudo supervisorctl restart all
Are you sure that supervisord is installed and running? Is there a socket file in present at
The error indicates that
supervisorctl, the control CLI, cannot reach the UNIX socket to communicate with
supervisord, the daemon.
You could also check
/etc/supervisor/supervisord.conf and see if the values for the
supervisorctl sections match.
Note that this is a Ubuntu-level problem, not a problem with Python, Django or nginx and as such this question probably belongs on ServerFault.
On Ubuntu 16+ it seems to been caused by the switch to systemd, this workaround may fix for new servers:
# Make sure Supervisor comes up after a reboot. $ sudo systemctl enable supervisor # Bring Supervisor up right now. $ sudo systemctl start supervisor
and then do check your status of iconic.conf [My example] of supervisor
$ sudo supervisorctl status iconic
PS: Make sure gunicorn should not have any problem while running.
The error maybe due to that you don’t have privilege.
Maybe you can fix the error by this way,open your terminal,and input
vim /etc/supervisord.conf to edit the file,search the lines
;chmod=0700 ; socket file mode (default 0700)
and delete the Semicolon in the start of the string
;chmod=0700,restart your supervisord.I suggest you do it.
Make sure that in
/etc/supervisor.conf the following two sections exists
[unix_http_server] file=/tmp/supervisor.sock ; path to your socket file [rpcinterface:supervisor] supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
You can do something like this :-
sudo touch /var/run/supervisor.sock sudo chmod 777 /var/run/supervisor.sock sudo service supervisor restart
It’s definitely work, try this.
In my case, Supervisor was not running. To spot the issue I run:
sudo systemctl status supervisor.service
The problem was that I had my logs pointing to a non-existing directory, so I just had to create it.
I hope it helps 🙂
