Django+nginx+uwsgi deployment

install python

Download the source package in python:

wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
# unzip
tar -zxf Python-3.6.5.tgz
cd Python-3.6.5

#compile

./configure --prefix=/appliocation/python3 --enable-optimizations

make && make install

# Configure environment variables
vim ~/.bash_prefile

# Add python's bin path to this line, as follows  
export PATH=$HOME/bin:/usr/local/python3/bin:/usr/local/bin:$PATH

source ~/.bash_profile

　　install django

pip3 isntall django==1.11.8 #Create
 a django project 
django- admin startproject hello_django
cd hello_django
#Create application 
python3 manager.py startapp app01 #Create
 uwsgi configuration file vim hello_django.ini #Enter

myweb_uwsgi.ini file [uwsgi]



# Django-related settings 

socket = :8080
 # The port of the real service

# Django project root directory (absolute path) 
chdir = /root/ hello_django

# The location of the wsgi.py file in the project 
module = hello_django.wsgi

# process-related settings
# master
master          = true

#Number of processes running
processes       = 4

# ... with appropriate permissions - may be needed
# chmod-socket    = 664
# clear environment on exit
vacuum          = true


# ##Install uwsgi 
pip install uwsgi

start uwsgi

uwsgi hello_django/ hello_django.ini
It can only be accessed after modification in seeing.py, the default is only localhost, as follows
ALLOWED_HOSTS = ['192.168.0.75', '127.0.0.1', 'localhost']

Configure Nginx

Find nginx.conf and write the following

server {
         #here is the port 
        listen 80 used for access ;
        server_name  localhost;

        charset UTF-8;

        client_max_body_size 75M;
        location / {
                include uwsgi_params;
                #Same as uwsgi content 
                uwsgi_pass 127.0.0.1:8080 ;
                 #Link timeout 
                uwsgi_read_timeout 30 ;
        }
    }

In this way, restart your nginx, access port 80, and you can see the effect.

Still have questions?

You may have discovered that the static resources on your web page cannot be accessed! ! For example, the admin page will be particularly rudimentary, because when nginx+uwsgi+Django, Django's processing of static resources, nginx cannot proxy (maybe). In short, this kind of thing should not be done by Django, because nginx is more capable of processing static resources. For static resources, let nginx handle it. 
Generally speaking, you will have two kinds of static resources /media/at the beginning of the link and /static/the beginning. Static is used to process original pictures, videos, js, css files of some websites. Django supports this kind of link by itself. So how to close /static/the file that Django processes at the beginning, it is very simple, change setting.pythe DEBUGvalue in False, at this time, Django will not process /static/the file. 
So /media/what? Generally speaking, we will save the pictures uploaded by users and use them when they are displayed on the webpage /media/.setting.py

MEDIA_URL = ' /media/ '  #Access prefix link 
MEDIA_ROOT = os.path.join(BASE_DIR, ' ../media ' ) #The specific location where the file is stored

url.pyadd in

from django.conf import settings
from django.conf.urls.static import static
if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

This means that when DEBUG=True, the file will be parsed /media/, and the location where the file is stored is the second parameter. 
In this way, when deploying as a production environment, you only need to change DEBUG to False, and Django will not deal staticwith mediait.

Collect static files

Django has a tool that collects all the static files used in the application for easy parsing by nginx. Specifically:  Set the static files collected in this way into the above directory
. How to run this tool?setting.pySTATIC_ROOT = os.path.join(BASE_DIR, '../collectedstatic') 
python3 manager.py collectstatic

Configure nginx to parse static files

Similarly, nginx.conf 
First, add 
user root 
a statement at the top of the file to let the root user run nginx, otherwise access to static files may prompt no permission 
. Second, location /add the following content before the configuration file mentioned above

      location /static/ {
            autoindex is;
            alias /root/SchoolBuyWeb/collectedstatic/;
        }

        location /media/ {
            autoindex is;
            alias /root/SchoolBuyWeb/media/;
        }

After paying attention alias, you can correspond to the directory you set yourself! 
Restart nginx, now it's ok~~
