Do you mean to create the socket manually? Haven't tried that. 

The directory and all its parents are owned by the user running gunicorn 
and also have 777 permissions. I am no sure I understand what you mean by - 
"The user isn't in one of the new group cause he is logged in" . 
Is it possible the reason to be something from the virtual env since the 
directory  /webapps/my-app/run/ is inside virtual env path. 

Thanks,
Kaloian

Well it appears to be a permission issue after all, but I really 
cannot understand why. I tried to change the directory for the sock 
file from /webapps/my-app/run/gunicorn.sock to /sockets/gunicorn.sock 
and gunicorn started normally. I tried to give full permissions to 
/webapps/my-app/run/ but still no success. I never tried to create the 
sock file myself and the /webapps/my-app/run/ dir is empty all the 
time. I cannot understand what is stopping gunicorn from creating the 
sock file in this directory.


Did you try to sudo to the user running gunicorn and creating the socket?
Some hints:
- The user can't access the directory cause he is not allowed to index 
one of his parent

- The user isn't in one of the new group cause he is logged in
- ... ?

Most of the time sudo to the user is useful for me

A UNIX socket is like a TCP connection, except it's represented as
a file. gunicorn is supposed to create it on startup and destroy
it on shutdown, and it shouldn't be present when gunicorn is not
running.

Maybe you tried to create /path/to/my/gunicorn.sock yourself, and
the file is now garbage? Try deleting it. Otherwise, another
instance of gunicorn may be running already. Try "ps aux | grep
gunicorn" or "lsof -U | grep gunicorn" if you're on Linux. Also,
the user running gunicorn_start must have access to create files
in /path/to/my/

Re: Gunicorn sock file is missing?

[Kaloian]

Hi Erik, and thanks for the help. 

Well it appears to be a permission issue after all, but I really cannot 
understand why. I tried to change the directory for the sock file from 
/webapps/my-app/run/gunicorn.sock to /sockets/gunicorn.sock and gunicorn 
started normally. I tried to give full permissions to /webapps/my-app/run/ 
but still no success. I never tried to create the sock file myself and the 
/webapps/my-app/run/ dir is empty all the time. I cannot understand what is 
stopping gunicorn from creating the sock file in this directory.

Re: Gunicorn sock file is missing?

[Kaloian]

Hi Erik,

No it doesn't start at all, running the gunicorn_start script gives: 


*[ERROR] Retrying in 1 second.*
*[ERROR] Retrying in 1 second.*
*[ERROR] Retrying in 1 second.*
*[ERROR] Retrying in 1 second.*
*[ERROR] Retrying in 1 second.**[ERROR] Can't connect to 
/path/to/my/gunicorn.sock *

This is why I thought that the missing sock file is failing it to start. Do 
you think it could be something else? 
I have already tried to add the absolute path in gunicorn_start but nothing 
changed. 

Thanks,
Kaloian

Is gunicorn even running? If not, you ned to find out why it failed to start, 
or why it crashed. As a start, try adding the absolute path to gunicorn in your 
gunicorn_start script instead of just "exec gunicorn".

Gunicorn sock file is missing?

[Kaloian]

I have an ansible provisioned VM based on this one 
https://github.com/jcalazan/ansible-django-stack but for some reason trying 
to start Gunicorn gives the following error:

*Can't connect to /path/to/my/gunicorn.sock *

and in nginx log file:

*connect() to unix:/path/to/my/gunicorn.sock failed (2: No such file or 
directory) while connecting to upstream*

And the socket file is really missing in the specified directory. I have 
checked the permissions of the directory and they are fine.

Here is my gunicorn_start script:


NAME="{{ application_name }}" 
DJANGODIR={{ application_path }} 
SOCKFILE={{ virtualenv_path }}/run/gunicorn.sock 
USER={{ gunicorn_user }} GROUP={{ gunicorn_group }} 
NUM_WORKERS={{ gunicorn_num_workers }} 

# Set this to 0 for unlimited requests. During development, you might want to # 
set this to 1 to automatically restart the process on each request (i.e. your # 
code will be reloaded on every request). 
MAX_REQUESTS={{ gunicorn_max_requests }} 
echo "Starting $NAME as `whoami`" 
# Activate the virtual environment. 
cd $DJANGODIR 
. ../../bin/activate 
# Set additional environment variables. 
. ../../bin/postactivate 
# Create the run directory if it doesn't exist. 
RUNDIR=$(dirname $SOCKFILE) test -d $RUNDIR || mkdir -p $RUNDIR 
# Programs meant to be run under supervisor should not daemonize themselves # 
(do not use --daemon). 
exec gunicorn \ --name $NAME \ 
--workers $NUM_WORKERS \ 
--max-requests $MAX_REQUESTS \ 
--user $USER --group $GROUP \ 
--log-level debug \ 
--bind unix:$SOCKFILE \ 
{{ application_name }}.wsgi


Can anyone point me to any direction what could be causing the missing 
gunicorn.sock file ?

Thanks
