如何在生產(chǎn)上部署Django?

Django的部署可以有很多方式，采用nginx+uwsgi的方式是其中比較常見的一種方式。

?uwsgi介紹

uWSGI是一個(gè)Web服務(wù)器，它實(shí)現(xiàn)了WSGI協(xié)議、uwsgi、http等協(xié)議。Nginx中HttpUwsgiModule的作用是與uWSGI服務(wù)器進(jìn)行交換。

要注意 WSGI / uwsgi / uWSGI 這三個(gè)概念的區(qū)分。

1. WSGI是一種Web服務(wù)器網(wǎng)關(guān)接口。它是一個(gè)Web服務(wù)器（如nginx，uWSGI等服務(wù)器）與web應(yīng)用（如用Flask框架寫的程序）通信的一種規(guī)范。
2. uwsgi是一種線路協(xié)議而不是通信協(xié)議，在此常用于在uWSGI服務(wù)器與其他網(wǎng)絡(luò)服務(wù)器的數(shù)據(jù)通信。
3. 而uWSGI是實(shí)現(xiàn)了uwsgi和WSGI兩種協(xié)議的Web服務(wù)器。
4. uwsgi協(xié)議是一個(gè)uWSGI服務(wù)器自有的協(xié)議，它用于定義傳輸信息的類型（type of information），每一個(gè)uwsgi packet前4byte為傳輸信息類型描述，它與WSGI相比是兩樣?xùn)|西。

?uwsgi性能非常高

uWSGI的主要特點(diǎn)如下

1. 超快的性能
2. 低內(nèi)存占用（實(shí)測(cè)為apache2的mod_wsgi的一半左右）
3. 多app管理（終于不用冥思苦想下個(gè)app用哪個(gè)端口比較好了-.-）
4. 詳盡的日志功能（可以用來分析app性能和瓶頸）
5. 高度可定制（內(nèi)存大小限制，服務(wù)一定次數(shù)后重啟等）

總而言之uwgi是個(gè)部署用的好東東，正如uWSGI作者所吹噓的：

If you are searching for a simple wsgi-only server, uWSGI is not for you, but if you are building a real (production-ready) app that need to be rock-solid, fast and easy to distribute/optimize for various load-average, you will pathetically and morbidly fall in love (we hope) with uWSGI.

Uwsgi 安裝使用

1 # Install the latest stable release:
2 pip install uwsgi
3 # ... or if you want to install the latest LTS (long term support) release,
4 pip install https://projects.unbit.it/downloads/uwsgi-lts.tar.gz

安裝uwsgi

基本測(cè)試

Create a file called?test.py:

# test.py
def application(env, start_response):start_response('200 OK', [('Content-Type','text/html')])return [b"Hello World"] # python3#return ["Hello World"] # python2

運(yùn)行

uwsgi --http :8000 --wsgi-file test.py

用uwsgi啟動(dòng)Django

uwsgi --http :8000 --module midware.wsgi

可以把參數(shù)寫到配置文件uwsgi.ini

[uwsgi]
http = :9000
# the local unix socket file than commnuincate to Nginx
socket = 127.0.0.1:8001
# the base directory (full path)
chdir = /home/ubuntu/midware
# Django's wsgi file
wsgi-file = midware/wsgi.py
# maximum number of worker processes
processes = 4
# thread numbers startched in each worker process
threads = 2
# monitor uwsgi status
stats = 127.0.0.1:9191
# clear environment on exit
vacuum = true

用uwsgi啟動(dòng)Django

ubuntu@ubuntu:~/midware$ uwsgi uwsgi.ini

?用uwsgitop監(jiān)控

安裝uwsgitop

sudo pip3 install uwsgitop

進(jìn)行監(jiān)控

uwsgitop  :9191   #9191是配置文件中的監(jiān)控進(jìn)行127.0.0.1:9191　　

安裝Nginx

sudo apt-get install nginx
sudo /etc/init.d/nginx start    # start nginx
sudo /etc/init.d/nginx restart    # restart nginx

為你的項(xiàng)目生成Nginx配置文件

You will need the?uwsgi_params?file, which is available in the?nginx?directory of the uWSGI distribution, or from?https://github.com/nginx/nginx/blob/master/conf/uwsgi_params

Copy it into your project directory. In a moment we will tell?nginx?to refer to it.

Now create a file called mysite_nginx.conf, and put this in it:

# uwsgi_params   #把這個(gè)文件從/etc/nginx/拷貝到項(xiàng)目midware下。
[uwsgi]
http = :9000
# the local unix socket file than commnuincate to Nginx
socket = 127.0.0.1:8001
# the base directory (full path)
chdir = /home/ubuntu/midware
# Django's wsgi file
wsgi-file = midware/wsgi.py   #每個(gè)Django項(xiàng)目都會(huì)有一個(gè)名為wsgi.py的文件。
# maximum number of worker processes
processes = 4
# thread numbers startched in each worker process
threads = 2
# monitor uwsgi status
stats = 127.0.0.1:9191   #uwsgitop監(jiān)控的就是它
# clear environment on exit
vacuum = true

文件mysite_nginx.conf

# 放到/etc/nginx/sites-enabled下，或者放到項(xiàng)目midware下，然后鏈接到/etc/nginx/sites-enabled（建立短鏈接ln -s mysite_nginx.conf /etc/nginx/sites-enabled/）# mysite_nginx.conf# the upstream component nginx needs to connect to
upstream django {# server unix:///path/to/your/mysite/mysite.sock; # for a file socketserver 127.0.0.1:8001; # for a web port socket (we'll use this first)    #uwsgi.ini中的the local unix socket（socket = 127.0.0.1:8001）
}# configuration of the server
server {# the port your site will be served onlisten      8000;      #用戶訪問的端口# the domain name it will serve forserver_name .example.com; # substitute your machine's IP address or FQDN    #服務(wù)器名稱charset     utf-8;# max upload sizeclient_max_body_size 75M;   # adjust to taste   #用戶請(qǐng)求最大為75M# Django medialocation /media  {alias /path/to/your/mysite/media;  # your Django project's media files - amend as required}location /static {alias /home/ubuntu/midware/static; # your Django project's static files - amend as required   #靜態(tài)文件路徑}# Finally, send all non-media requests to the Django server.location / {uwsgi_pass  django;include     /home/ubuntu/midware/uwsgi_params; # the uwsgi_params file you installed    #把這個(gè)文件放到項(xiàng)目目錄，或者/etc/nginx/sites-enabled/uwsgi_params}
}

啟動(dòng)uwsgi、重啟Nginx

Deploying static files

Before running?nginx, you have to collect all Django static files in the static folder. First of all you have to edit mysite/settings.py adding:

# 文件settings.py
DEBUG = False   #生成環(huán)境中不能用DEBUG模式


STATIC_ROOT = os.path.join(BASE_DIR, "all_tatic_files")
 ?#把所有靜態(tài)文件放到一個(gè)文件夾下，注意不要與"static"重名，否則會(huì)被覆蓋。

?

?最后執(zhí)行

python manage.py collectstatic   #合并靜態(tài)文件

不要忘了，修改mysite_nginx.conf中的靜態(tài)文件配置
