uwsgi+nginx在ubuntu14.04上部署django项目

注意：这里默认已经有完成的django项目，本文不做相关django项目介绍

1.通过python pip安装uwsgi：

sudo apt-get install python-dev
sudo apt-get install python-pip
sudo pip install --upgrade pip 
sudo pip install uwsgi

2.安装成功后查看uwsgi版本：

uwsgi --version

3.运行django服务(python manage.py runserver 8000)，测试uwsgi，这里要通过django的wsgi启动，wsgi.py 在项目目录下(如：项目名为hello，则wsgi.py应该在hello/hello下)：

大致内容如下：

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "hello.settings")
 
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

然后终端里运行：

uwsgi --http :8000 --module hello.wsgi

显示出是否正常工作

4.在django项目下创建uwsgi.ini文件和log文件夹：

touch uwsgi.ini

内容如下：

[uwsgi]
socket=127.0.0.1:9000  # uwsgi运行端口
chdir=/home/ubuntu/my_site/  # 项目位置
module=my_site.wsgi:application
vacuum=True
master=True
workers=4
enable-threads=True
threads=10
pidfile=/home/ubuntu/my_site/log/uwsgi.pid
daemonize=/home/ubuntu/my_site/log/uwsgi-production.log
memory-report=True

5.安装nginx服务器：

sudo apt-get install nginx-full

6.配置nginx文件：

cd /etc/nginx/conf.d/
touch default.conf

将以下内容放入default.conf中：

server{
     listen   80;
     charset  utf-8;
     location ~ ^/static {
         root   /home/cloud/my_site;   # 项目static文件夹所在目录
     }
     location / {
         uwsgi_pass    127.0.0.1:9000;   # uwsgi运行端口
         include    /etc/nginx/uwsgi_params;  
     }
}

确保/etc/nginx下有uwsgi_params文件：

uwsgi_param  QUERY_STRING       $query_string;
uwsgi_param  REQUEST_METHOD     $request_method;
uwsgi_param  CONTENT_TYPE       $content_type;
uwsgi_param  CONTENT_LENGTH     $content_length;
 
uwsgi_param  REQUEST_URI        $request_uri;
uwsgi_param  PATH_INFO          $document_uri;
uwsgi_param  DOCUMENT_ROOT      $document_root;
uwsgi_param  SERVER_PROTOCOL    $server_protocol;
uwsgi_param  REQUEST_SCHEME     $scheme;
uwsgi_param  HTTPS              $https if_not_empty;
 
uwsgi_param  REMOTE_ADDR        $remote_addr;
uwsgi_param  REMOTE_PORT        $remote_port;
uwsgi_param  SERVER_PORT        $server_port;
uwsgi_param SERVER_NAME $server_name;

然后在nginx目录下创建default的软连接：

ln -s /etc/nginx/conf.d/default.conf /etc/nginx/default.conf

7.如果静态文件目录用户权限是root，则需要更改/etc/nginx.conf文件（一般都在第一行的位置）：

将 user  www-data 改为 user  root

8.重启nginx服务并启动uwsgi服务（在django项目下）：

service nginx restart
uwsgi -i uwsgi.ini

正常输出如下：

[uWSGI] getting INI configuration from uwsgi.ini

注: 如果执行完上述步骤后报类似No Python application found的错误，则先执行

aptitude install uwsgi-plugin-python

然后重启uwsgi即可

经过以上步骤，django项目基本上就部署完成了
