I got a 502 error when I'm trying to open a website. I used the instructions from the official website link
Added new file lifeline.conf at /etc/supervisor/conf.d/

I checked the asgi log file and it contains an error .
daphne: error: the following arguments are required: application
I'm guessing a mistake in lifeline.conf.
I am assuming you are not passing asgi application to daphne, because configuration you pasted in question has missing line. You have to pass it correctly. Assuming you have conf package with asgi.py module inside it containing asgi application instance, you have to do
command=/home/ubuntu/Env/lifeline/bin/daphne -u /run/daphne/daphne%(process_num)d.sock conf.asgi:application
conf.asgi:application should be at the end.

I have been on this for a month now without a working solution. Everything works fine in production but I have been trying to deploy my django-channels application using nginx as reverse proxy, supervisor to keep servers running, gunicorn to serve http requests and I am stuck at the weboscket request part using daphne to process http requests.
I am bindig with unix sockets: gunicorn.sock and daphne.sock

Please ask for any other thing needed, I'll update as quickly as I can. Thank You.
It's a chatting application, do you think I should use only Daphne, I'm considering the scalability, and that's why I used gunicorn to serve http requests. Hosting on Ubuntu Server
Try putting socket=tcp://0.0.0.0:8001 or socket=tcp://localhost:8001 in your [program:serverinterface] part of supervisord.conf. After that read your supervisor_log.log file to find out how it behaves. I had similar problems with it too. I hope that this helps. Use socket=tcp://localhost:8001 if it's inside of docker container. And make sure that nginx container is on the same docker network as that container.
I have setup Django using nginx, gunicorn and postgres as per below url.

Now I am trying to access swagger ui.
Nginx is up and running however showing default page.
When I run the same project using,
python manage.py runserver myip:8000
and then access the same url I can see actual swagger ui with rest end points.
I am not sure what I am doing wrong here.
Here is what I have added to nginx file.
server {
listen 80;
server_name <myipaddress>;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /home/threat-dashboard/backend;
}
location / {
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://unix:/tmp/backend.sock;
}
}
There was a mistake in sock file path. I corrected it from /tmp/backend.sock to /tmp/backend/backend.sock and it resolved the issue.
I am learing nginx for django, i am running the server in locally with docker.
this is my django_nginix.conf file :
server {
listen 80;
listen [::]:80 default_server;
server_name musicaldd.com;
client_max_body_size 90M;
location /media/ {
root /home/pyking/cpd/musicaldd_back/storage/;
}
location /static/ {
root /home/pyking/cpd/musicaldd_back/storage/;
}
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $host;
proxy_redirect off;
proxy_buffering off;
proxy_pass http://djangoapp:8000/;
}
}
When I run the server creating docker images and hit the URLs, it returns me 502-bed getaway timeout | nginix Can anyone tell me why this errors occuse, how can I fix this error
It may stupid question but this is very serious to me, coz, i am new on Nginx, it will really much be appreciated if you help me to fix this
If you are using uwsgi add this to your nginx.conf file based on your uwsgi params file location.
include /etc/nginx/uwsgi_params;
uwsgi_pass unix://tmp/uwsgi.sock;
uwsgi_param SCRIPT_NAME /;
If you are not i suggest use that. there is another option called gunicorn but uwsgi has better performance.
I have a situation here with my Nginx reverse proxy configuration. My distribution is Ubuntu 14.04
I have a domain, let's call it foo.bar.net, and I want the /grafana endpoint to redirect to my grafana server (localhost:3000), the /sentry endpoint to redirect to my sentry server (localhost:9000) and finally, the /private endpoint to redirect to my django server (localhost:8001). I am using gunicorn for the tuneling between django and nginx.
Here is what I tried :
server {
# listen on port 80
listen 80 default_server;
# for requests to these domains
server_name foo.bar.net;
location /sentry {
# keep logs in these files
access_log /var/log/nginx/sentry.access.log;
error_log /var/log/nginx/sentry.error.log;
# You need this to allow users to upload large files
# See http://wiki.nginx.org/HttpCoreModule#client_max_body_size
# I'm not sure where it goes, so I put it in twice. It works.
client_max_body_size 0;
proxy_pass http://localhost:9000;
proxy_redirect off;
proxy_read_timeout 5m;
allow 0.0.0.0;
# make sure these HTTP headers are set properly
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location /grafana {
proxy_pass http://localhost:3000;
proxy_redirect off;
proxy_read_timeout 5m;
allow 0.0.0.0;
# make sure these HTTP headers are set properly
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location /private {
proxy_pass http://127.0.0.1:8001;
}
location /private/static/ {
autoindex on;
alias /home/user/folder/private/static/;
}
}
The server won't even start correctly, the config is not loading.
I would also like the / path to redirect to the private endpoint if possible.
Additionally, I am not even sure where to put this configuration (sites-available/??)
Can anyone help me with that ?
Thanks a lot,
There are some missing semicolons and other syntax errors. Look at main nginx error log for details and fix them one by one.
Where to put that config file depends on your distribution. For some of them it should be sites-available directory and symlink to that file inside sites-enabled directory for quick enabling and disabling sites, if you don't have sites-available and sites enabled directory, you should put it into conf.d dir in your distribution.
I'm developing with apache2 ( mpm-worker ) + mod_wsgi behind nginx which is silly since I have to sudo apache2ctl graceful for every update I make in anything but the template files.
My nginx conf is:
server {
listen 80;
server_name site.org;
access_log /www/site.org/log/access.log;
error_log /www/site.org/log/error.log;
location / {
proxy_pass http://127.0.0.1:8080/;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Magic-Header "secret";
client_max_body_size 10m;
}
}
Would it be a matter of just binding proxy_pass to 127.0.0.1:3000 if 3000 is the port used by the django server?
Ack, didn't realize it was this easy... I..
copied the server {} settings into another file
changed the port to 3001
changed the server name to dev.site.org
updated my host records in the DNS to point to my server IP
restarted nginx
did manage.py runserver 3001.
All is well :)
