I have been following this tutorial to deploy my django project on Digital Ocean. I am trying to configure gunicorn.
My project structure looks similar to this:
On my settings.py I use DEBUG=False
I create the gunicorn.socket and gunicorn.service.
/etc/systemd/system/gunicorn.socket
[Unit]
Description=gunicorn socket
[Socket]
ListenStream=/run/gunicorn.sock
[Install]
WantedBy=sockets.target
/etc/systemd/system/gunicorn.service
[Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target
[Service]
User=someuser
Group=www-data
WorkingDirectory=/home/someuser/myproject

--access-logfile - \
--workers 3 \
--bind unix:/run/gunicorn.sock \
Myproject.wsgi:application
[Install]
WantedBy=multi-user.target
I start and enable the Gunicorn socket:
sudo systemctl start gunicorn.socket
sudo systemctl enable gunicorn.socket
Check the status of the process to find out whether it was able to start:
sudo systemctl status gunicorn.socket
This is what I get and then it returns to the command line.
Failed to dump process list, ignoring: No such file or directory

May 04 23:12:03 myproject systemd[1]: Listening on gunicorn socket.
Next, I check for the existence of the gunicorn.sock file within the /run directory:
file /run/gunicorn.sock
/run/gunicorn.sock: socket
It seems that a file or directory doesn't exist, but it doesn't provide any more details. The gunicorn.sock seems to exist.
I am familiar with Python but not with servers and deploying so I am at a loss here.
I have successfully followed the similar tutorial for Ubuntu 16.04 a few months ago, but now I keep hitting issues.
I know, that's old question, but...
I haved some error. In my case wrong WorkingDirectory and application with modul wsgi. I think that's error in "myproject.wsgi:application"
This is actually an issue with your usage of systemd. You need to refer to the name of the service in your calls to systemctl, not the socket as you're doing. In your case the service will be called gunicorn because you've named your systemd unit file as gunicorn.service.
systemctl enable gunicorn
systemctl start gunicorn

I just change socket file destination (home/facealatoo(user)/) and gunicorn destination (usr/local/bin/gunicorn). And these actions solved my problem)))
I am running a virtualenv with Python3.6 on Ubuntu 16.04 for my Django project using uwsgi and NGINX.
I have uWSGI installed globally and also in the virtualenv.
I can run my project from the command line using uWSGI within the env with
/home/user/Env/myproject/bin/uwsgi --http :8080 --home /home/user/Env/myproject --chdir /home/user/myproject/src/myproject -w myproject.wsgi
and go to my domain and it loads fine.
However I am obviously running uWSGI in "Emperor mode" and when I set the service file up (along with NGINX) the domain displays internal server error.
The uWSGI logs trace to --- no python application found ---
I was having this problem when running
uwsgi --http :8080 --home /home/user/Env/myproject --chdir /home/user/myproject/src/myproject -w myproject.wsgi
because it was using the global install uwsgi instead of the virtualenv one.
I changed my StartExec to the virtualenv uwsgi path but no luck.
I can't figure out what I'm doing wrong, path error? Syntax error?
my /etc/systemd/system/uwsgi.service file

Okay bit silly but it seems I ran sudo systemctl stop uwsgi and then sudo systemctl start uwsgi and it works now.
I am trying to setup a simple flask application served by Nginx and Gunicorn and have mostly followed this tutorial. When trying to access the webpage, I get a 502 Bad Gateway error.
The nginx log (/var/log/nginx/error.log) says :
[crit] 23472#0: *1 connect() to unix:/home/crawforc3/webpage/webpage.sock failed (13: Permission denied)
I checked and there is a webpage.sock file in my project directory that looks like this:
srwxrwxrwx 1 crawforc3 www-data 0 May 31 17:59 webpage.sock
Here is my /etc/systemd/system/gunicorn.service
[Unit]
Description=gunicorn daemon
After=network.target
[Service]
User=crawforc3
Group=www-data
WorkingDirectory=/home/crawforc3/webpage
Environment="PATH=home/crawforc3/miniconda3/envs/HALSWEBPAGE/bin"
ExecStart=/home/crawforc3/miniconda3/envs/HALSWEBPAGE/bin/gunicorn --workers 3 --bind unix:/home/crawforc3/webpage/webpage.sock -m 007 wsgi:app
[Install]
WantedBy=multi-user.target
I discovered that there was a discrepancy with /etc/nginx/nginx.conf
I had the user set as www-data and I should have set it as crawforc3. Making this change and restarting nginx and gunicorn resolved the issue.
I set up a VPS (django + gunicorn + nginx ) and it was working fine showing default django screen, but after I updated my django code and made all migrations I thought that now I need to restart gunicorn to apply changes.
So I did this:
sudo systemctl restart gunicorn
After this I've got Internal Server Error
Everything is set up like here
gunicorn.service :
[Unit]
Description=gunicorn daemon
After=network.targett
[Service]
User=thekotik
Group=www-data
WorkingDirectory=/home/thekotik/glboy
ExecStart=/home/thekotik/glboy/denv/bin/gunicorn --workers 3 --bind unix:/home/thekotik/glboy/closer.sock closer.wsgi:application
[Install]
WantedBy=multi-user.target
<class 'socket.error'>, [Errno 13] Permission denied: file: /usr/lib/python2.7/socket.py line: 228
unix socket files holds the same case unix file permissions; the file ( /home/thekotik/glboy/closer.sock) is currently being used or not owned by gunicorn process user that causes error 13.
I recommend using the TCP option --bind 127.0.0.1:8000.For tcp based changes,
gunicorn.service
[Unit]
Description=gunicorn daemon
After=network.targett
[Service]
User=thekotik
Group=www-data
WorkingDirectory=/home/thekotik/glboy
ExecStart=/home/thekotik/glboy/denv/bin/gunicorn --workers 3 --bind 127.0.0.1:9090 closer.wsgi:application
[Install]
WantedBy=multi-user.target
use above systemd service file for gunicorn & change the proxy option in nginx to
proxy_pass http://127.0.0.1:9090$request_uri;
that will avoid unix socket file based permission problems.
Hi I have deployed Django using UWSGI and Nginx using following tutorial http://uwsgi-docs.readthedocs.io/en/latest/tutorials/Django_and_nginx.html
Everything is running fine. I face a challenge while updating python code. I don't know the efficient way to deploy new changes.
after hit and trial, I used following commands to deploy
git pull; sudo service uwsgi stop; sudo service nginx restart; sudo service uwsgi restart; /usr/local/bin/uwsgi --emperor /etc/uwsgi/vassals
this command works fine. But I face following problems
Usagi runs in the foreground. Every time I make changes, a new UWSGI instance start running.
Due to multiple UWSGI instances, My AWS server get crashed, due to memory exhaustion.
I want to know what commands should I run to reflect changes in python code.
PS: in my previous APACHE Django setup, I only used to restart apache, is it possible to reflect changes by only restarting nginx.
Try this:
git pull
python manage.py migrate # to run any migrations
sudo service uwsgi restart
Press Ctrl + Z and then bg + enter
This should run the process in the background.
Please let me know if this works.
Please have a look at this for running uwsgi in background. create an .ini file /etc/uwsgi/sites/projectname.ini. The script would look like this(for ubuntu 16.04):
[uwsgi]
project = projectname
base = projectpath
chdir = %(base)/%(project)
home = %(base)/Env/%(project)
module = %(project).wsgi:application
master = true
processes = 5
socket = %(base)/%(project)/%(project).sock
chmod-socket = 666
vacuum = true
(For ubuntu 16.04):
then create the following systemd script at /etc/systemd/system/uwsgi.service:
[Unit]
Description=uWSGI Emperor service
After=syslog.target
[Service]
ExecStart=/usr/local/bin/uwsgi --emperor /etc/uwsgi/sites
Restart=always
KillSignal=SIGQUIT
Type=notify
StandardError=syslog
NotifyAccess=all
[Install]
WantedBy=multi-user.target
Refresh the state of the systemd init system with this new uWSGI service on board
sudo systemctl daemon-reload
In order to start the script you'll need to run the following:
sudo systemctl start uwsgi
In order to start uWSGI on reboot, you will also need:
sudo systemctl enable uwsgi
You can use the following to check its status:
systemctl status uwsgi
(For ubuntu 14.04):
Create an upstart script for uWSGI:
sudo nano /etc/init/uwsgi.conf
Then add following lines in the above created file:
description "uWSGI application server in Emperor mode"
start on runlevel [2345]
stop on runlevel [!2345]
setuid user
setgid www-data
exec /usr/local/bin/uwsgi --emperor /etc/uwsgi/sites
