Introduction to Ubuntu14.04 Deployment examples

The first step.

Digitalocean django nginx ubuntu 18

sudo apt-get update

Django ubuntu nginx 

sudo apt-get upgrade

Update First:

The main way to deploy Django: Nginx+uwsgi+django

502 bad gateway nginx 1.10 3 ubuntu django

Step two, install Nginx

sudo apt-get install Nginx

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

Nginx's approximate file structure.

1. configuration file:/etc/nginx

2. Procedure:/usr/sbin/nginx

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

Step three, 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 increase the download speed.) Create a pip.conf write under ~/.pip

[Global]

Trusted-host = pypi.douban.com

UWSGI is a Web server that implements protocols such as WSGI Protocol, UWSGI, HTTP, and so on. The role of Httpuwsgimodule in Nginx is to exchange with the UWSGI server.

The approximate process is: client <==>nginx<==>uwsgi<==>django. The static request is handled by Nginx itself. Non-static requests are passed through Uwsgi to Django, which is processed by Django to complete a Web request.

Create a Django test project, Django-admin startproject mysite,cd mysite,python manage.py startapp demo1.

Fourth step, Test Uwsgi

Create a new test file under the MySite directory, nano test.py.

Write:

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

Run:

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

Access is normal.

Fifth Step, 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.

Sixth Step, configure Uwsgi

The UWSGI supports booting through a variety of configuration files, using the INI configuration file method.

New Uwsgi:nano Uwsgi.ini

# Mysite_uwsgi.ini FILE[UWSGI]    socket = 127.0.0.1:3400# django-related Settings    # The Django project directory (f ull path)    chdir           =/home/ubuntu/mysite    # Django ' s wsgi filemodule          = Mysite.wsgi    # process-related Settings    # Master    Master          = true# Maximum number of worker processes    processes       = 2threads = 2max-requests = 6000# ... with appropriate permissions-may is neededchmod-socket    = 664# clear Environment on exitvacuum          = True

Access times wrong,invalid request block size: 21573 (max 4096)...skip.

The reason is that the URL address is more than 4,096 characters, because we start with a socket, change the configuration file socket to HTTP, or modify the buffer-size.

(It is recommended not to make changes, the test is changed to HTTP, etc., when the connection Nginx, change back to the socket)

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

The formal runtime adds this code to the Uwsgi.ini file, and the access log is spooled to the Uwsgi.log

At this point Django has access to it.

Seventh Step, configure Nginx

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

server {    # The port your site is served on    listen      ;    # The domain name it would serve Forserver_name 127.0.0.1; # Substitute your machine ' s IP address or fqdncharset     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/stat Ic # 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;# Consistent with UWSGI configuration file here    }}

Remember to modify the configuration of the Uwsgi.ini when testing.

Eighth step, run

Restart Nginx and run Uwsgi.

Done

For the time being, follow-up continues to add Nginx, Django, Uwsgi knowledge.

Most of the configuration from Baidu Search, do not post each source. Life is short.
