Step one.

 

sudo apt-get update

sudo apt-get upgrade

Update first.

The mainstream deployment of Django: nginx+uwsgi+django

 

Step 2, Install nginx

sudo apt-get install nginx

Install nginx. If you need to install the latest nginx, you need to download the source package from the official website for manual compilation.

The approximate file structure of nginx.

1. Configuration file: /etc/nginx

2. Program: /usr/sbin/nginx

3. Log: /var/log/nginx/access.log - error.log

 

Step 3, Install uwsgi

sudo apt-get install python3-dev

sudo apt-get install python3-pip

sudo pip3 install uwsgi (before this step, you can replace the PIP source to improve download speed.Create a pip.conf write under ~/.pip

[global]

trusted-host = pypi.douban.com

index-url = http://pypi.douban.com/simple)

 

Uwsgi is a web server that implements WSGI, uwsgi, http and other protocols.The role of HttpUwsgiModule in Nginx is to exchange with the uWSGI server.

The general flow is client <=>nginx<=>uwsgi<=>Django.Static requests are handled by Nginx itself.Non-static requests are passed to Django via uwsgi and processed by Django to complete a WEB request.

 

Create a Django test project, django-admin startproject mysite, cd mysite, Python management.py startapp demo1.

 

 

 

Step 4, Test uwsgi

Create a new test file in the mysite directory, nano test.py.

Write in:

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

Function:

uwsgi --http :8001 --plugin python --wsgi-file test.py

Access is normal.

 

Step 5, Test Django

python manage.py runserver 0.0.0.0:8002

Access is normal.

 

Connect Django and uwsgi.

uwsgi --http:8001 --plugin python --module mysite.wsgi

Access is normal.

 

Step 6, Configure uwsgi

uwsgi supports booting through multiple profiles, using the ini profile approach here.

 

New uwsgi:nano uwsgi.ini

 

# mysite_uwsgi.ini file
    [uwsgi]

    socket = 127.0.0.1:3400
    # Django-related settings
    # the django project directory (full path)
    chdir           = /home/ubuntu/mysite
    # Django's wsgi file
    module          = mysite.wsgi

    # process-related settings
    # master
    master          = true
    # maximum number of worker processes
    processes       = 2

    threads = 2
    max-requests = 6000

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

 

 

Error accessing, invalid request block size: 21573 (max 4096)...skip.

The reason is that the url address exceeds 4096 characters, because we started with a socket, changed the socket of the configuration file to http, or modified the buffer-size.

(It is recommended that you do not make any changes, change to http for testing, and return to socket when nginx is connected)

daemonize = /home/ubuntu/mysite/uwsgi.log

Add this code to the uwsgi.ini file at regular runtime and the access log will be output to uwsgi.log in the background

django is now accessible.

 

 

Step 7, Configure nginx

Modify nginx's default profile/etc/nginx/sites-enabled/default

server {
    # the port your site will be served on
    listen      80;
    # the domain name it will serve for
    server_name 127.0.0.1; # substitute your machine's IP address or FQDN
    charset     utf-8;

    # max upload size
    client_max_body_size 75M;   # adjust to taste

    # Django media
    location /media  {
        alias /home/ubuntu/mysite/media;  # your Django project's media files - amend as required
    }

    location /static {
        alias /home/ubuntu/mysite/static; # your Django project's static files - amend as required
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        include     uwsgi_params; # the uwsgi_params file you installed
        uwsgi_pass 127.0.0.1:8001;#This is consistent with the uwsgi configuration file
    }
}

Remember to modify the configuration of uwsgi.ini during the test.

Step 8, Run

 

Restart nginx and run uwsgi.

Be accomplished

 

 

For the time being, continue to supplement the knowledge of nginx, django, uwsgi.

Most of the configurations come from Baidu Search, so we won't paste each source one by one.Life is short.
