在共享开发环境中使用Django，Gunicorn和Ngnix提供静态内容

Question

I have seen many great answers to this question here on SO, but either I don't understand them or they don't apply to my particular circumstance. I have looked here: Serving static files with Nginx + Gunicorn + Django and many others. I have followed the recommendation in those answers and I still do not have solution that works. I hope that if I explain exactly what I am doing then maybe someone will tell me where I went wrong.

I developing in a shared environment with several other teams and we share an ngnix server. I have a Django project on this shared server, sre-dev.example.com . The path to the Django project is /apps/capman/capman_port10001/capman .

In my settings.py I have these values set:

STATIC_ROOT = '/apps/capman/capman_port10001/capman/static'
STATIC_URL = '/static/'
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'corsheaders',
    'rest_framework',
    'rest_framework.authtoken',
    ...
    'django_db_logger',
    'rest_framework_swagger'
]

I have created a /etc/nginx/sites-enabled directory and sym link,

ln -s /apps/capman/capman_port10001/capman/nginx.conf caasa-dev.example.com

I also created alias (CNAME), caasa-dev.example.com in our DNS for sre-dev . And in added a nginx.conf file, /apps/capman/capman_port10001/capman/nginx.conf with the contents of:

server {
    listen 10001;
    server_name caasa-dev.example.com;

    location /static {
        alias /apps/capman/capman_port10001/capman/static/;
    }
}

I have executed ...

python manage.py collectstatic

... several times now and the files are there:

$ pwd
/apps/capman/capman_port10001/capman/static
$ ls
admin  rest_framework  rest_framework_swagger

I have restarted nginx and gunicron. I have a systemd configuration for my gunicorn server so I can do stuff like:

systemctl restart gnuicorn-capman.service

If I do systemctl -l status gnuicorn-capman.service I get this output:

# systemctl -l status gnuicorn-capman.service

Yet still when I attempt to go to caasa-dev.example.com:10001/admin/login/?next=/admin/ I do not get my static content:

I also get messages like this ...

... "GET /static/admin/css/base.css HTTP/1.1" 404 2793 "http://caasa-dev.example.com:10001/admin/login/?next=/admin/" "Mozilla/5.0 (Macintosh; Intel Mac OS X

... in my access.log.

So what have I left out? What am I doing wrong?

Update: If I go to caasa-dev.example.com:10001/static/ I the standard Django 404 error page.

Update 2:

For some reason my log files are empty:

Update 3:

Thanks Ivan but should my /apps/capman/capman_port10001/capman/nginx.conf be:

server {
    listen 80;
    server_name caasa-dev.example.com;

    location /static {
        alias /apps/capman/capman_port10001/capman/static/;
    }

    location / {
        proxy_pass http://127.0.0.1:10001;
    }
}

or

server {
    listen 10001;
    server_name caasa-dev.example.com;

    location /static {
        alias /apps/capman/capman_port10001/capman/static/;
    }

    location / {
        proxy_pass http://127.0.0.1:80;
    }
}

Update 4:

I just noticed that my /etc/nginx/nginx.conf does not include my sites-enabled directory:

[root@sre-dev nginx]# grep -r include *
nginx.conf:include /usr/share/nginx/modules/*.conf;
nginx.conf:    include             /etc/nginx/mime.types;
nginx.conf:    # See http://nginx.org/en/docs/ngx_core_module.html#include
nginx.conf:    include /etc/nginx/conf.d/*.conf;
nginx.conf:        include /etc/nginx/default.d/*.conf;
nginx.conf:#        include /etc/nginx/default.d/*.conf;
nginx.conf.default:    include       mime.types;
nginx.conf.default:        #    include        fastcgi_params;

Should I add the line ...

include /etc/nginx/sites-enabled/*.conf

... to my /etc/nginx/nginx.conf and if so where in that file?

Answer 1

gunicorn --workers 4 capman.wsgi --bind 0.0.0.0:10001

nginx: listen 10001;

I guess nginx did not even start (see equal port?). All the requests are processed by Django. Change port.

And if this is full Nginx config you have then it's missing proxy_pass block to forward requests to django

Answer 2

The problem is that u are using gunicorn to serve django but nginx is not listening on that port so that reverse proxy ith to you domain name. use this nginx config:

server {
listen 80;
server_name caasa-dev.example.com;

location /static {
    alias /apps/capman/capman_port10001/capman/static;
}

location / {
    proxy_pass http://127.0.0.1:10001;
}
}

In this config, nginx with act as a reverse proxy, and route all traffic to port 80 of your domain, to internal network 127.0.0.1:10001 which is handled by gunicorn.

note you are using gunicorn on address 0.0.0.0 . I donot recommend that. change it to 127.0.0.1 instead or use linux .sock files for better config.
