1, 安装 uwsgi

pip install uwsgi

2, 测试 uwsgi

新建测试文件

$ vim test.py

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

启动uwsgi，并测试

$ uwsgi --http :8000 --wsgi-file test.py

$ curl -i http://localhost:8000

3, 通过 uwsgi 来启动django

# 原始启动方式，通过manage.py
$ python manage.py runserver 0.0.0.0:8000
# 使用uwsgi
$ uwsgi --http :8000 --chdir /usr/share/nginx/html/django-blog --wsgi-file /usr/share/nginx/html/django-blog/mysite/wsgi.py
# 测试
$ curl -i http://localhost:8000

4，利用Nginx转发请求，uwsgi执行python

配置Nginx文件

# mysite_nginx.conf

# the upstream component nginx needs to connect to
upstream django {
    server 127.0.0.1:8000; # for a web port socket (we'll use this first)
}

# configuration of the server
server {
    # the port your site will be served on
    listen      80;
    # the domain name it will serve for
    server_name django.luckybird.me; # substitute your machine's IP address or FQDN
    charset     utf-8;
    
    access_log  /var/log/nginx/dj-access.log main;
    error_log   /var/log/nginx/dj-error.log;

    # max upload size
    client_max_body_size 75M;   # adjust to taste


    location /static {
        alias /usr/share/nginx/html/django-blog/static; # your Django project's static files - amend as required
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  django;
        include     /etc/nginx/uwsgi_params; # the uwsgi_params file you installed
    }
}

重启Nginx

5，通过 uwsgi 来启动django，并请求Nginx端口

# 使用uwsgi
$ uwsgi --http :8000 --chdir /usr/share/nginx/html/django-blog --wsgi-file /usr/share/nginx/html/django-blog/mysite/wsgi.py
# 测试80端口
$ curl -i http://localhost

至此，将Nginx、uwsgi、django整合在一起了

uwsgi还可以采用socket方式启动

1,添加socket配置文件

# mysite_uwsgi.ini file
[uwsgi]

# Django-related settings
# the base directory (full path)
chdir           = /usr/share/nginx/html/django-blog
# Django's wsgi file
wsgi-file       = /usr/share/nginx/html/django-blog/mysite/wsgi.py
# the virtualenv (full path)
home            = /usr

# process-related settings
# master
master          = true
# maximum number of worker processes
processes       = 10
# the socket (use the full path to be safe
socket          = /usr/share/nginx/html/django-blog/mysite/mysite.sock
# ... with appropriate permissions - may be needed
chmod-socket    = 666
# clear environment on exit
vacuum          = true

2,通过socket方式启动uwsgi

# 测试文件
$ uwsgi --socket mysite.sock --wsgi-file test.py --chmod-socket=666
# django项目
$ uwsgi --socket mysite.sock --chdir /usr/share/nginx/html/django-blog --wsgi-file /usr/share/nginx/html/django-blog/mysite/wsgi.py --chmod-socket=666

3,修改Nginx配置文件，然后重启

upstream django {
	server unix:///usr/share/nginx/html/django-blog/mysite/mysite.sock; # for a file socket

    #server 127.0.0.1:8000; # for a web port socket (we'll use this first)
}

4，测试

# 测试80端口
$ curl -i http://localhost

遇到问题

uwsgi: invalid option -- 'x'

原因：centos下，在没有安装libxml2时，pip安装的uwsgi无法支持xml格式的配置文件
解决：

yum install libxml*
pip uninstall uwsgi
pip install uwsgi

ImportError: Import by filename is not supported.

原因：使用 –module 参数，找不到wsgi module，或者指向 –wsgi-file 文件 wsgi.py
方法：

--wsgi-file wsgi.py
