使用uwsgi+nginx运行django程序

环境

1. Ubuntu:14.04
2. Python:2.7

部署代码

1. 代码说明：样例代码参考Django官方例子 https://docs.djangoproject.com/en/1.10/intro/tutorial01/
2. 代码位置:https://github.com/Eric-aihua/django_sample

安装软件

uwsgi

pip install uwsgi

Nginx

apt-get install nginx

Django

pip install django

验证uwsgi

初始化project

假设github上的代码已经下载到/root/django_sample 目录,执行以下命令

root@ubuntu:~/django_sample# python manage.py migrate
Operations to perform:
  Apply all migrations: admin, auth, contenttypes, polls, sessions
Running migrations:
  Applying contenttypes.0001_initial... OK
  Applying auth.0001_initial... OK
  Applying admin.0001_initial... OK
  Applying admin.0002_logentry_remove_auto_add... OK
  Applying contenttypes.0002_remove_content_type_name... OK
  Applying auth.0002_alter_permission_name_max_length... OK

  Applying polls.0003_user_zipcode... OK
  Applying sessions.0001_initial... OK

## 修改project 配置文件
django_sample/settings.py 文件的下列配置，需要修改为本机的IP

ALLOWED_HOSTS = ['192.168.116.131','127.0.0.1','localhost']

使用uwsgi启动django的project

 root@ubuntu:~/django_sample# uwsgi --http :8000 --module django_sample.wsgi

到目前为止，已经成功使用uwsgi启动了django工程，通过在浏览器中输入http://192.168.116.131:8000/polls/ 可以开始访问系统

# 配置Nginx
# 添加配置文件
在/root/django_sample 下创建两个文件
1. uwsgi_params：内容来自https://github.com/nginx/nginx/blob/master/conf/uwsgi_params

1. django_nginx.conf 内容如下

 # mysite_nginx.conf

# the upstream component nginx needs to connect to
upstream django {
    # server unix:///path/to/your/mysite/mysite.sock; # for a file socket
    server 127.0.0.1:8001; # for a web port socket (we'll use this first)
}

# configuration of the server
server {
    # the port your site will be served on
    listen      8000;
    # the domain name it will serve for
    server_name .example.com; # substitute your machine's IP address or FQDN
    charset     utf-8;

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

    # Django media
    location /media  {
        alias /root/django_sample/media;  # your Django project's media files - amend as required
    }

    location /static {
        alias /root/django_sample/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     include     /root/django_sample/uwsgi_params; # the uwsgi_params file you installed
    }
}

1. 让Nginx加载project的nginx配置文件

root@ubuntu:~/django_sample# ln -s /root/django_sample/django_nginx.conf /etc/nginx/sites-enabled/

1. 启动Nginx

/etc/init.d/nginx start

1. 启动uwsgi

root@ubuntu:~/django_sample# uwsgi --socket :8001 --module django_sample.wsgi

此处的端口配置与mysite_nginx.conf 中upstream的配置相同

上述启动方式输入参数比较多，也可以将启动配置添加到ini文件中，创建django_sample_uwsgi.ini,内容如下:

[uwsgi]

# Django-related settings
# the base directory (full path)
chdir           = /root/django_sample
# Django's wsgi file
module          = django_sample.wsgi
# the virtualenv (full path)
#home            = /path/to/virtualenv

# process-related settings
# master
master          = true
# maximum number of worker processes
processes       = 1
# the socket (use the full path to be safe
socket          = :8001
# ... with appropriate permissions - may be needed
# chmod-socket    = 664
# clear environment on exit
vacuum          = true

启动方式为:root@ubuntu:~/django_sample# uwsgi –ini django_sample_uwsgi.ini

到目前为止，数据访问链路已经基本畅通,请求链路为:the web client <-> the Nginx <-> the socket <-> uWSGI <-> Django

访问路径:http://192.168.116.131:8000/polls/
