Nginx + Systemd/Systemctl + Django not working (502 bad gateway) -

-

i've been @ hours , yet cannot figure out why setup isn't working. if run command that's in exec on own, can access page through browser fine. when try run service, 502: bad gateway.

i first tried using unix sockets, when didn't work, plugged in ip , port directly, still no luck.

gunicorn.service:

[unit] description=gunicorn daemon after=network.target  [service] user=username workingdirectory=/home/username/naomiselect environment="path=/home/username/naomiselect/naomienv/bin" execstart=/home/username/naomiselect/naomienv/bin/gunicorn --workers 3 --bind local_ip:8000 naomiselect.wsgi:application  [install] wantedby=multi-user.target

nginx.conf:

user www-data; worker_processes auto; pid /run/nginx.pid;  events {     worker_connections 768;     # multi_accept on; }  http {      ##     # basic settings     ##      sendfile on;     tcp_nopush on;     tcp_nodelay on;     keepalive_timeout 65;     types_hash_max_size 2048;     # server_tokens off;      # server_names_hash_bucket_size 64;     # server_name_in_redirect off;      include /etc/nginx/mime.types;     default_type application/octet-stream;      ##     # ssl settings     ##      ssl_protocols tlsv1 tlsv1.1 tlsv1.2; # dropping sslv3, ref: poodle     ssl_prefer_server_ciphers on;      ##     # logging settings     ##      access_log /var/log/nginx/access.log;     error_log /var/log/nginx/error.log;      ##     # gzip settings     ##      gzip on;     gzip_disable "msie6";      # gzip_vary on;     # gzip_proxied any;     # gzip_comp_level 6;     # gzip_buffers 16 8k;     # gzip_http_version 1.1;     # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;      ##     # virtual host configs     ##      include /etc/nginx/conf.d/*.conf;     include /etc/nginx/sites-enabled/*; }

sites-available/naomiselect:

server {     listen 80;     server_name local_ip;      location = /favicon.ico { access_log off; log_not_found off; }     location /static/ {         root /home/username/naomiselect;     }      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://local_ip:8000/;     } }

the directory group , owner www-data , username, respectively, recursively, permissions drwxrwxr-x.

i have no idea i'm doing incorrectly when i've referenced several tutorials , tried different methods , none of them work.

so (in comments) status gunicorn.service says "exited" rather "running" after start it.

most of times, means service type= misconfiguration. default type=simple, expects non-forking process. probably, daemon forks background after startup, confuses systemd:

if set simple (the default if neither type= nor busname=, execstart= specified), expected process configured execstart= main process of service.

if set forking, expected process configured execstart= call fork() part of start-up. parent process expected exit when start-up complete , communication channels set up.

so, check hypothesis, run daemon binary shell. if releases shell immediately, daemon "forking" , need pass corresponding option in unit file:

[service] type=forking

i'm new python/django , created simple django website using pycharm. site works fine running on computer, i'm lost when comes taking site onto host (dreamhost). i'm able upload files correct directories fine, , believe made correct changes database on mysql. i'm not sure go there though. right now, page shows files rather site. direction appreciated. much! you should not run django application using python manage.py runserver on production. how run application on django depends on server (apache, nginx) want use for apache - https://docs.djangoproject.com/en/1.10/howto/deployment/wsgi/modwsgi/ for nginx - https://www.digitalocean.com/community/tutorials/how-to-serve-django-applications-with-uwsgi-and-nginx-on-ubuntu-14-04 the mysql database should, of course, exist , have correct credentials. or, if choose use sqlite, file should accessible, readable , writable www-user (may different depending on linux distributive)
