invalid parameter server_name in /etc/nginx/sites-enabled/django

I've deployed a Django application on DigitalOcean.
First off, when i try to secure this with https and ssl, I get this error.
when i run nginx -t :
nginx: [emerg] invalid parameter "server_name" in /etc/nginx/sites-enabled/django:12

}
}
server {
listen 80;
server_name domain.com;
return 301 https://$host$request_uri;
}
Furthermore, I can access the website using the ip address but not the domain name registered.It results in a 400 bad request page.
Could this be an issue with the settings.py ?
for reference in settings.pyALLOWED_HOSTS=['*']. What list do I provide in the ip_addresses() function?
Are these two problems related?
using Django v1.10.5

You're missing semicolons on a bunch of lines, that's why nginx -t is failing.

django production deployment does not load static files

I've been trying for about a whole day to deploy Django's static files in production, but till now I had no luck, so I absolutely need community's help!
My nginx config is:
worker_processes 1;
user nobody nogroup;
pid /tmp/nginx.pid;
error_log /tmp/nginx.error.log;
events {
worker_connections 1024;
accept_mutex off;
}
http {
include mime.types;
default_type application/octet-stream;
access_log /tmp/nginx.access.log combined;
sendfile on;
upstream app_server {
server unix:/tmp/gunicorn.sock fail_timeout=0;
# For a TCP configuration:
# server 192.168.0.7:8000 fail_timeout=0;
}
server {
listen 80 default;
client_max_body_size 4G;
server_name _;
keepalive_timeout 5;
# path for static files
root /home/ubuntu/src/static;
location / {
# checks for static file, if not found proxy to app
try_files $uri #proxy_to_app;
}
location #proxy_to_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
}
error_page 500 502 503 504 /500.html;
location = /500.html {
root /home/ubuntu/src/static;
}
}
}
and in my django settings.py file I've set the following:
STATIC_URL = '/static/'
STATICFILES_DIRS = ()
STATICFILES_FINDERS = (
'django.contrib.staticfiles.finders.FileSystemFinder',
'django.contrib.staticfiles.finders.AppDirectoriesFinder',
)
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
and of course I've run the collectstatic django command and the folder in path /home/ubuntu/src/static exists containing all appropriate files.
Still my deployment does not server any static file :/
Does anybody have any idea what might be wrong with my setup?
Thank you in advance

I used a great tutorial here for my setup. Hopefully this can help. One obvious change I can see is using location /static/ for static files and just forwarding location / straight to gunicorn (or uwsgi in my case)

Add static alias to server conf
location /static {
alias /home/ubuntu/src/static; # your Django project's static files - amend as required
}
Full configuration should be like
server {
listen 80 default;
client_max_body_size 4G;
server_name _;
keepalive_timeout 5;
# path for static files
# root /home/ubuntu/src/static;
location /static {
alias /home/ubuntu/src/static; # your Django project's static files - amend as required
}
location / {
# checks for static file, if not found proxy to app
try_files $uri #proxy_to_app;
}
location #proxy_to_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
}
error_page 500 502 503 504 /500.html;
location = /500.html {
root /home/ubuntu/src/static;
}
}
}

Nginx config does not work for two subdomains

I'm trying to get the following setup to work with gunicorn and nginx. Everything works until I add the second server config...
upstream app_server_djangoapp {
server localhost:8002 fail_timeout=0;
}
server {
listen 80;
server_name api.domain.tld;
access_log /var/log/nginx/guni-access.log;
error_log /var/log/nginx/guni-error.log info;
keepalive_timeout 5;
# Size in megabytes to allow for uploads.
client_max_body_size 20M;
# path for static files
root /home/username/webapps/guni/static;
location /docs/ {
autoindex on;
alias /srv/site/docs/buildHTML/html/;
}
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
if (!-f $request_filename) {
proxy_pass http://app_server_djangoapp;
break;
}
}
}
server {
listen 80;
server_name flower.domain.tld;
location / {
proxy_pass http://localhost:5555;
}
What I'm I doing wrong? I need to have two subdomains one mapped to my django app and other mapped to my monitoring software on 5555 (flower)
log files states:
2014/11/21 12:03:27 [emerg] 962#0: unexpected end of file, expecting
"}" in /etc/nginx/sites-enabled/default:47

Your code is missing a closing "}" at the very end:
server {
listen 80;
server_name flower.domain.tld;
location / {
proxy_pass http://localhost:5555;
}
}
For future reference:
You can run nginx -t (with sudo if needed) to test the configuration before reloading nginx - this will give you a quite good description of any errors you might have in your configuration file(s).

How to correctly set virtual hosts on Ningx?

Trying to setup Nginx handling 2 domains I stucked with some problems. While my setup with two domains works correctly with static html handling, tried to push forward and start two python apps behind Nginx. I tried with some differents wsgi containers, and different micro frameworks, but the problem is that Nginx can't handle virtual hosts, rather it serves only one app at both domain adresses.
Here is Nginx conf:
user www-data;
worker_processes 8;
pid /var/run/nginx.pid;
events {
worker_connections 768;
}
http {
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
server_names_hash_bucket_size 64;
include /etc/nginx/mime.types;
default_type application/octet-stream;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
gzip on;
gzip_disable "msie6";
server {
listen 80;
server_name www.domainA.com;
root /var/www/domainA.com;
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Originating-IP $remote_addr;
proxy_set_header HTTP_REMOTE_ADDR $remote_addr;
proxy_set_header REMOTE_ADDR $remote_addr;
proxy_set_header CLIENT_IP $remote_addr;
proxy_pass http://127.0.0.2:7000;
}
}
server {
listen 80;
server_name www.domainB.com;
root /var/www/domainB.com;
location / {
... ... blah blah...same story...except this proxy pass.....
proxy_pass http://127.0.0.1:5000;
}
}
}
Any help ?
EDIT:
Just tried to add empty server block as 1st block and it return 404.

Are these outward facing websites?
If you put the full ip in your listen clause you should start working correctly.
listen 512.548.595.485:80;
Right now you have the server ip for both sites which is causing a conflict.
Hope this helps.

In the senario where virtual hosts share an ip and port, nginx selects the right virtual host by comparing the Host header sent by the client to each servers' server_name entry. If you have curl use the following to see exactly what you're sending for the Host header:
curl -s --trace-ascii - http://www.domainA.com | grep 'Host:'
To make your server_name more flexible use the .example.com notation. This is shorthand for example.com and *.example.com. Or just add as many server_name entries as you need.
Next confirm your apps are listening on the right ips and ports. Shell into your server and try:
curl -I 'http://127.0.0.1:5000'
curl -I 'http://127.0.0.2:7000'

Finally I ended with such problem. In testing conditions I didn't add all flavours which would make Nginx satisfied. Then I found THIS LINK :
If the “Host” header field does not match a server name, NGINX will route the request to the default server for this port. The default server is the first one listed in the nginx.conf file. This will be overridden if the default_server parameter is set in the listen directive within a server context. An example is given below.
Nginx docs and tutorials are dispersed on few web locations so finding few doesn't mean that you got all answers you need.

I think, this is your solution. Create a BASH file whose name should be virtualhost.sh. Copy and paste the following code:
#!/bin/bash
domain=$1
root="/data/$domain"
block="/etc/nginx/sites-available/$domain"
# Create the Document Root directory
mkdir -p $root
# Assign ownership to your regular user account
chown -R $USER:$USER $root
# Create the Nginx server block file:
tee $block > /dev/null <<EOF
server {
listen 80;
listen [::]:80;
root /data/$domain;
index index.php index.html index.htm;
server_name $domain www.$domain;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_buffer_size 128k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 256k;
include fastcgi_params;
}
location ~ /\.ht {
access_log off;
log_not_found off;
deny all;
}
location ~* \.(jpg|jpeg|gif|png|css|js|ico|xml)$ {
access_log off;
log_not_found off;
expires 30d;
}
location = /favicon.ico {
log_not_found off;
access_log off;
}
location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}
}
EOF
# Link to make it available
ln -s $block /etc/nginx/sites-enabled/
# Test configuration and reload if successful
nginx -t && service nginx reload
You need call this BASH file:
virtualhost.sh www.yourdomain.com

Nginx, uwsgi and flask does not display the css file

I have set up uwsgi and nginx to serve a flask website that I'm working on but it refuses to display the css file even though it appears in the body of the page correctly and I can view it. It does not change the styling of the page.
I use the following nginx.conf
