Nginx + uwsgi + django + websocket(dwebsocket)環境部署

1.安裝nginx(/export/servers/nginx/)###

保證/export/servers/nginx/是nginx的安裝目錄
/export/servers/nginx/conf/domain/xxx應用配置文件

2.部署django環境,保證python manage.py runserver 0.0.0.0:8000能正常跑起來,websocket能調通###

1.項目名稱:Python_20160906,里面有2個應用
2.一個應用名字叫app,一個叫做api
3.項目路徑/export/App/DevOPS/Python_20160906

uwsgi相關的東西在下圖這個配置文件中(項目settings.py文件目錄下)

3.uwsgi###

(1)安裝

pip install uwsgi

(2)測試是否安裝成功(uwsgi開啟服務)

--home:指定virtualenv的環境目錄,如果沒用virtualenv的話不用指定可選
--chdir:指定django項目的根路徑:/export/App/DevOPS/Python_20160906
-w 指定django項目的wsgi文件位置,就是如圖2的東西(因為項目目錄為/export/App/DevOPS/Python_20160906,項目目錄下還有個同名目錄Python_20160906,存放項目配置文件的地方,里面有個wsgi.py文件,所以寫作Python_20160906.wsgi)
# uwsgi --http :8000 --home /home/siva/Env/first --chdir /export/App/DevOPS/Python_20160906 -w Siva_First.wsgi
uwsgi --http :8000 --chdir /export/App/DevOPS/Python_20160906 -w Python_20160906.wsgi

(3)直接訪問驗證

curl http://127.0.0.1:8000/

4.寫uwsgi配置文件(肯定不能手工命令起啊)###

mkdir -p /export/servers/nginx/conf/uwsgi/
cd /export/servers/nginx/conf/uwsgi/
vim Python_20160906.ini

<1>project:項目名
<2>chdir:指定django項目的根路徑
<3>module:對應了上面命令行啟動的-w參數,指定django項目的wsgi文件位置
<4>master:是否有主進程
<5>processes:幾個工作進程
<6>socket:創建的socket套接字文件位置
<7>chmod-socket:套接字權限
<8>vacuum:當服務器退出的時候自動刪除unix socket文件和pid文件

[uwsgi]
project = Python_20160906
 
chdir = /export/App/DevOPS/%(project)
module = %(project).wsgi
 
master = true
processes = 5
 
socket = /export/App/DevOPS/%(project)/%(project).sock
chmod-socket = 664
vacuum = true

5.開啟uwsgi服務(啟動后會創建sock套接字文件)###

uwsgi --ini /export/servers/nginx/conf/uwsgi/Python_20160906.ini &

6.變更nginx配置文件###

map $http_upgrade $connection_upgrade {
        default upgrade;
        ''   close;
}
server
                {
	
                listen                   80;
                server_name              devops.xx.com devops.xx.local;
                access_log               /export/servers/nginx/logs/devops.xx.local/devops.xx.local_access.log main;
                error_log                /export/servers/nginx/logs/devops.xx.local/devops.xx.local_error.log warn;
                error_page 400 401 402 403 404 405 408 410 412 413 414 415 500 501 502 503 506 = http://www.jd.com/error2.aspx;

      location / {
				include         /export/servers/nginx/conf/uwsgi_params;

			autoindex_localtime on; 
        }
}

8.重啟nginx###

/etc/init.d/nginx restart

9.uwsgi支持django后端的websocket(dwebsocket模塊)###

(1)修改django項目的settings.py,添加一條數據

WEBSOCKET_FACTORY_CLASS = 'dwebsocket.backends.uwsgi.factory.uWsgiWebSocketFactory'

(2)修改uwsgi的配置文件,添加異步選項

async = 30
ugreen = ''
http-timeout = 300

(3)重啟uwsgi服務

killall uwsgi
