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

1.安装nginx(/export/servers/nginx/)###

保证/export/servers/nginx/是nginx的安装目录

/export/servers/nginx/conf/domain/xxx应用配置文件

2.部署django环境,保证python manage.py runserver 0.0.0.0:8000能正常跑起来,websocket能调通###

1.项目名称:Python_20160906,里面有2个应用

2.一个应用名字叫app,一个叫做api

3.项目路径/export/App/DevOPS/Python_20160906



uwsgi相关的东西在下图这个配置文件中(项目settings.py文件目录下)

3.uwsgi###

(1)安装

pip install uwsgi

(2)测试是否安装成功(uwsgi开启服务)

--home:指定virtualenv的环境目录,如果没用virtualenv的话不用指定可选
--chdir:指定django项目的根路径:/export/App/DevOPS/Python_20160906
-w 指定django项目的wsgi文件位置,就是如图2的东西(因为项目目录为/export/App/DevOPS/Python_20160906,项目目录下还有个同名目录Python_20160906,存放项目配置文件的地方,里面有个wsgi.py文件,所以写作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)直接访问验证

curl http://127.0.0.1:8000/

4.写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:项目名

<2>chdir:指定django项目的根路径

<3>module:对应了上面命令行启动的-w参数,指定django项目的wsgi文件位置

<4>master:是否有主进程

<5>processes:几个工作进程

<6>socket:创建的socket套接字文件位置

<7>chmod-socket:套接字权限

<8>vacuum:当服务器退出的时候自动删除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.开启uwsgi服务(启动后会创建sock套接字文件)###

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

6.变更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;

			autoindex_localtime on;
        }
}

8.重启nginx###

/etc/init.d/nginx restart

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

(1)修改django项目的settings.py,添加一条数据

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

(2)修改uwsgi的配置文件,添加异步选项

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

(3)重启uwsgi服务

killall uwsgi
