python--Django+uwsgi+nginx

uwsgi+Django

View uwsgi version and information: cmd - >> uwsgi

First, to test whether the normal use uwsgi

1. Create a test file index.py
vim index.py

write the code below:

def application(env, start_response):
    start_response('200 OK', [('Content-Type','text/html')])
    return [b"Hello World"]

run:

uwsgi --http :9090 --wsgi-file index.py

Then you can access through a browser ip + port to see the Hello Worid

2. Add the concurrent (to increase processing speed)
uwsgi --http: 9090 --wsgi-File index.py --processes 4 --threads 2

Then it is to deploy a Django.

 

1. Create an ini file in the project root directory

vim uwsgi.ini

Write the code:

[Uwsgi]
http = 0.0.0.0:8000
chdir = /usr/www/DjangoSpider/
wsgi-file = DjangoSpider/wsgi.py
processes = 4
threads = 2

NOTE: Django in ALLOWED_HOSTS = [] to ALLOWED_HOSTS = [ '*']

 

2. Start

uwsgi uwsgi.ini 

Then you can add ip port access through the deployment of a good project, but this time a static file is not showing up, and we need to show we can configure nginx perfect.

 

uwsgi+nginx+Django

 

1.cd default.conf modify the file into the '/etc/nginx/cond.d' directory (it is recommended to keep a copy of the source file)

 

server {
    listen       80;
    localhost server_name;    # Uniform Domain Name provided by external users

    # Forwards the request to the dynamic server uwsgi 
    LOCATION / {
         # comprises request parameters uwsgi 
        the include uwsgi_params;
         # care uwsgi request to the server (server uwsgi ip and port) 
        uwsgi_pass 127.0.0.1:8000;   # single server uwsgi (no load equilibrium) 
        # uwsgi_pass upstream1; 
    }

    # If it is a static resource request is a direct response resources. 
    LOCATION / static {
         # specify the directory to store static files (. need to modify / usr / ... directory operating authority chmod 777 $ / usr) 
        Alias / usr / the WWW / project name / static / ;
    }
}

 

2. End modify the configuration file, to re reload it.

nginx -s reload

3. Request 80 interfaces, may appear permission problem, then you need to turn off selinux

setenforce 0

4. Collect static resources.

When the admin backend access without style, you need to collect Django static resources.

# Project name /settings.py (project configuration, STATIC_ROOT set the path to collect static resources): 
STATIC_URL = ' / static / ' 
STATICFILES_DIRS = [os.path.join (base_dir, ' static ' )]
 # Specifies the path to collect static files (need to modify / var / ... operating authority catalog) 
STATIC_ROOT = ' ./static '

Then run the command:

python manage.py collectstatic

ini file in the root directory 5. Modify project

vim uwsgi.ini

[uwsgi]
# http = 0.0.0.0:8000
Socket=0.0.0.0:8000
chdir = /usr/www/DjangoSpider/
wsgi-file = DjangoSpider/wsgi.py
processes = 4
threads = 2

 

Start:
Start nginx: systemctl start / restart nginx
project root directory: uwsgi uwsgi.ini

see whether nginx start: systemctl status nginx

When web access ip packet 502, should be the authority, so we need to run the corresponding command.
setenforce 0
