nginx部署django應用

　　Django部署方式有不少種，以前寫過一篇部署在Apache上的博文：http://www.javashuo.com/article/p-vqmzzkji-bt.html 。下文介紹的是經過Nginx來部署。

　　Nginx是一個高性能的HTTP和反向代理服務，運用很是普遍。Django應用能夠經過Nginx+uwsgi的方式進行部署。Nginx放置在服務器的最前端來接收全部web請求，統一管理，首先分離出靜態請求，本身作處理。而後，Nginx將非靜態請求經過uwsgi轉發給Django，由Django處理。

 

 1、安裝Nginx

  安裝Nginx命令

apt-get install Nginx

  Nginx的默認端口爲80，很容易被其餘服務佔用，所以須要修改爲其餘端口。打開文件 vi /etc/nginx/nginx.conf ，若是能找到監聽的端口，直接修改 。找不到的也不要緊 ，找到以下配置 ，說明是引用了其餘目錄的文件

... include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } ...

  打開 /etc/nginx/sites-enabled/ ，找到並編輯 default ，將80修改爲8088

# Default server configuration # server { listen 8088 default_server; listen [::]:8088 default_server; # SSL configuration # # listen 443 ssl default_server; # listen [::]:443 ssl default_server; # # Note: You should disable gzip for SSL traffic. # See: https://bugs.debian.org/773332
 # # Read up on ssl_ciphers to ensure a secure configuration. # See: https://bugs.debian.org/765782
 # # Self signed certs generated by the ssl-cert package # Don't use them in a production server!
 # # include snippets/snakeoil.conf;

  Nginx啓動命令

service nginx start service nginx restart service nginx stop

2、配置uwsgi

1.安裝  

  pip 安裝 uwsgi 命令：

pip install uwsgi

2.配置 uwsgi 和 Django 的鏈接  

  Django 項目路徑位於 /home/project/web/ ，在 Django 項目根目錄（manage.py 同級目錄）新建文件 uwsgi.ini （也支持 xml 文件格式）。在文件中添加以下內容：

# uwsgi.ini file [uwsgi] # Django-related settings socket = :8000 # the base directory (full path) chdir = /home/project/web # Django s wsgi file module = web.wsgi # process-related settings master = true # maximum number of worker processes processes = 5

#maximum number of worker threads
threads = 5

# try to remove all of the generated file/sockets vacuum = true

3. 配置 uwsgi 和 Nginx 的鏈接

  修改Nginx配置文件：vi /etc/nginx/sites-available/default ，增長一段配置。而後重啓Nginx

server { listen 8099; server_name 127.0.0.1 charset UTF-8; access_log /var/log/nginx/web_access.log; error_log /var/log/nginx/web_error.log; client_max_body_size 75M; location / { include uwsgi_params; # 經過uwsgi轉發請求 uwsgi_pass 127.0.0.1:8000; # 和上文配置的socket端口保持一致 uwsgi_read_timeout 15; # 設置請求超時時間 } location /static { # 訪問靜態資源 expires 30d; autoindex on; add_header Cache-Control private; alias /var/web/; } }

4.配置 Django 靜態資源

  在setting裏增長配置，靜態資源 路徑 和 Nginx 裏的訪問路徑一致

STATIC_ROOT = os.path.join(BASE_DIR,'/var/web')

  執行命令

Python manage.py collectstatic

5.最後啓動項目

cd /home/project/web uwsgi --ini uwsgi.ini

運行成功：
