> 使用 uwsgi 命令启动

$ uwsgi --http :8001 --chdir /data/github/django-cms --module cms.wsgi

> uwsgi 命令 + supervisord.conf

[program:cms1]
    command=uwsgi --http :8001 --chdir /data/github/django-cms --module cms.wsgi
    directory=/data/github/django-cms
    startsecs=0
    stopwaitsecs=0
    autostart=true
    autorestart=true

> uwsgi.ini + supervisord.conf + nginx.conf

推荐

*  uwsgi.ini

[uwsgi]
    socket = /home/ubuntu/cms.sock
    chdir = /data/github/django-cms
    wsgi-file = cms/wsgi.py
    touch-reload = /home/ubuntu/reload
     
    processes = 2
    threads = 4
     
    chmod-socket = 664
    #chown-socket = ubuntu:www-data
     
    vacuum = true

配置好了，可以测试

$ uwsgi uwsgi.ini --http :8002

*  supervisord.conf

[program:cms_app]
    command=uwsgi --ini /home/ubuntu/uwsgi.ini
    directory=/data/github/django-cms
    startsecs=0

*  nginx.conf

server {
        listen      8080;
        server_name 118.25.81.114;
        charset     utf-8;
    
        client_max_body_size 75M;
    
        location /media  {
            alias /data/github/django-cms/media;
        }
    
        ### method1 for static conf
        location /static {
            alias /data/github/django-cms/static;
        }
    
        ### method2 for static conf
        #location  ~/static/  {
        #    root   /data/github/django-cms;
        #    break;
        #}
    
        location / {
            uwsgi_pass  unix:///home/ubuntu/cms.sock;
            include     /data/nginx/conf/uwsgi_params;
        }
    }
