基於Nginx 和 uwsgi 搭建 django.

第一篇博客，不是很懂語法之類的，希望通過多寫點東西，記錄自己的成長，早點成為一個pyer.

就寫下這兩天折騰的這個nginx-uwsgi-django.

首先附上官方文檔鏈接 http://uwsgi-docs.readthedocs.io/en/latest/tutorials/Django_and_nginx.html

環境 python == Python 2.7.3, os == centos6.5 x86_64

      django == 1.8.1

      uwsgi == uWSGI 2.0.15 (64bit) #都是pip 直接安裝的

      nginx == 1.10.1      #yum install -y 

  1.剛剛創建的project 

$django-admin startproject test_nginx_uwsgi
$cd test_nginx_uwsgi/
$tree
.
├── manage.py
└── test_nginx_uwsgi
    ├── __init__.py
    ├── settings.py
    ├── urls.py
    └── wsgi.py

 

2.當前目錄下創建test.py文件，代碼如下：

#test.py 
def application(env, start_response):
    start_response('200 OK', [('Content-Type','text/html')])
    return "Hello World" #國際慣例,helloworld

 運行代碼：

$uwsgi --http :9111 --wsgi-file test.py
##中間東西很多,又看不懂，亂七八糟的,我就不貼了##
*** uWSGI is running in multiple interpreter mode ***
spawned uWSGI worker 1 (and the only) (pid: 19381, cores: 1)

參數含義簡介：

• :9111 > 想必大家都知道，運行的端口
• wsgi-file > 指定加載的文件
• 報錯[uwsgi: command not found]的話，ln -s /your-python-dir/bin/* /usr/bin/*

 

 如圖所示，第一步完成！

 

3.測試您的django 是否能夠正常運行！ps:為了方便起見我們直接用admin網站測試好了~~

$python manage.py syncdb #創建superuser
$python manage.py makemigration
$python manage.py migrate
$python manage.py runserver 0.0.0.0:9111

 

大家有目共睹

 

4.使用Uwsgi 跑 django項目

cmd: (其中test_nginx_uwsgi.wsgi指的就是test_nginx_uwsgi目錄下的wsgi.py，django1.8自動生成)

$ uwsgi --http :9111 --module test_nginx_uwsgi.wsgi

 又成功了一步~可以對比上面的，同樣的url，這里卻很難看，是因為沒有加載static文件

   但是可以說明  web-client <-> Uwsgi <-> Django 是連通的,下面的就要看Nginx.

 

5.配置Nginx.

由於版本的問題，如果這里也用官方的源碼就不行了。

1. 收集靜態文件

   #首先setting.py中添加
   STATIC_ROOT = '/root/django/test_nginx_uwsgi/static_root/'
   ------------------------------我是換行------------------------------
   
   $python manage.py collectstatic
   You have requested to collect static files at the destination
   location as specified in your settings:
   
       /root/django/test_nginx_uwsgi/static_root
   
   This will overwrite existing files!
   Are you sure you want to do this?
   
   Type 'yes' to continue, or 'no' to cancel: yes
   #·······省略~
   62 static files copied to '/root/django/test_nginx_uwsgi/static_root'.

    

2. nginx配置文件在 /etc/nginx/nginx.conf ,其中include -> /etc/nginx/conf.d/*.conf  [這個，相信大多數linux服務如出一轍]
3. vi /etc/nginx/conf.d/test_nginx_uwsgi.conf,代碼如下

   # test_nginx_uwsgi.conf
   
   # the upstream component nginx needs to connect to
   upstream django_test { #加上_test，因為和原來的沖突了，這里備注下
       # server unix:///path/to/your/mysite/mysite.sock; # for a file socket
       server 127.0.0.1:9111; # for a web port socket (we'll use this first) 類似uwsgi端口
   }
   # configuration of the server
   server {
       # the port your site will be served on
       listen      8090;  #nginx 運行端口
       # the domain name it will serve for
       server_name .example.com; # 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 /root/django/test_nginx_uwsgi/media;  # 加載你的meida,
       }
       location /static {
           alias /root/django/test_nginx_uwsgi/static_root; # 加載你的靜態文件
       }
       # Finally, send all non-media requests to the Django server.
       location / {
           uwsgi_pass  django_test;
           include     /etc/nginx/uwsgi_params; #官方說要把文件cp到項目目錄，感覺沒必要
       }
   }
   

4. 重啟 nginx (不知道是我這機器有毛病還是····，光restart不行) 

[root@lzy test_nginx_uwsgi]# /etc/init.d/nginx restart
stopping nginx.... Done.
starting nginx..
[root@lzy test_nginx_uwsgi]# nginx -c /etc/nginx/nginx.conf
[root@lzy test_nginx_uwsgi]# nginx -s reload
[root@lzy test_nginx_uwsgi]# lsof -i :8090
COMMAND  PID USER   FD   TYPE   DEVICE SIZE/OFF NODE NAME
nginx   1354 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1383 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1384 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1386 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1387 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1388 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1390 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1391 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1392 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1393 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1398 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1399 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1400 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1401 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1402 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1403 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
nginx   1404 root    9u  IPv4 87392561      0t0  TCP *:8090 (LISTEN)
#可以看到8090端口已經在運行 nginx 了,說明配置文件有效果了

 

6.接下來官網Balala了一堆,我這種fish壓根不懂，我也沒按他的做，跳過這一步··

 

7.配置test_nginx_uwsgi_uwsgi.ini 啟動配置文件

　　ps:參考了http://www.runoob.com/django/django-nginx-uwsgi.html

　　創建test_nginx_uwsgi_uwsgi.ini  就在項目根目錄

#test_nginx_uwsgi.ini file
[uwsgi]

# Django-related settings

socket = :9111
# the base directory (full path)
chdir = /root/django/test_nginx_uwsgi

# Django s wsgi file
module = test_nginx_uwsgi.wsgi

# process-related settings
# master
master = true

# maximum number of worker processes
processes = 4

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

 

8.配置完成，就剩下啟動了

 啟動就很簡單呢

#首先啟動uwsgi 指定配置文件ini
$uwsgi --ini test_nginx_uwsgi.ini #也可以 nohup uwsgi --ini test_nginx_uwsgi.ini & 后台執行，無輸出
#其次重啟Nginx,參照上面重啟步驟

#瀏覽器打開 192.168.8.199:8090/admin

 

大功告成~現在就是通過nginx端口打開的django，如果nginx Listen 80，那么瀏覽器不用輸端口也行呢
