Nginx/wsgi部署Django：避开502KeyError: u'REQUEST_METHOD'错误

Nginx/wsgi部署Django会有各种坑，主要是一些教程根本就不完整，都是抄过来的，所以按照教程就会遇到很多坑，最常见的就是502的坑，下面是我在部署的过程中，几个重要的文件，我就按照网上的教程操作，没有避开502KeyError: u'REQUEST_METHOD'错误，导致浪费了很多时间。

django项目目录结构

django文件结构

uwsgi.ini文件代码：

#mysite_uwsgi.ini file
[uwsgi]
# Django-related settings
# the base directory (full path)
chdir           = /var/www/yt
# Django's wsgi file
module          = yt.wsgi
# the virtualenv (full path)
# process-related settings
# master
master          = true
# maximum number of worker processes
processes       = 4 
# the socket (use the full path to be safe
socket          = 127.0.0.1:8888 
# ... with appropriate permissions - may be needed
chmod-socket    = 666
# clear environment on exit
vacuum          = true
socket-timeout  = 600
buffer-size     = 65535

uwsgi_params代码：

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 UWSGI_SCHEME $scheme;

uwsgi_param REMOTE_ADDR $remote_addr;

uwsgi_param REMOTE_PORT $remote_port;

uwsgi_param SERVER_PORT $server_port;

uwsgi_param SERVER_NAME $server_name;

这里一定要注意的是这里是uwsgi_param 不要搞成wsgi_param了，甚至有的教程，就是wsgi_param，最终会报502，我就是在这里被坑的，还是从github上下载的uwsgi_params这个文件，就是wsgi_param，所以坑死人不偿命。

如果你不幸下载了某个教程上叫你到github上下载的是wsgi_param，就会报下面的错误：

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/wsgi.py", line 167, in __call__
    request = self.request_class(environ)
  File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/wsgi.py", line 97, in __init__
    self.method = environ['REQUEST_METHOD'].upper()
KeyError: u'REQUEST_METHOD'

还有一个是nginx的配置文件，放在/etc/nginx/conf.d/目录下：命名为yt.conf

# the upstream component nginx needs to connect to
upstream django {
    #server unix:/var/www/yt/yt.sock; # for a file socket
    server 127.0.0.1:8888; # 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 192.168.0.5; # 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 /var/www/yt/media;  # your Django project's media files - amend as required
    }
    location /static {
        alias /var/www/yt/static; # your Django project's static files - amend as required
    }
    # Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  django;
	uwsgi_send_timeout 600;        # 指定连接到后端uWSGI的超时时间。
        uwsgi_connect_timeout 600;   # 指定向uWSGI传送请求的超时时间，完成握手后向uWSGI传送请求的超时时间。
        uwsgi_read_timeout 600;    
	keepalive_timeout 650;
        include     /var/www/yt/uwsgi_params; # the uwsgi_params file you installed
        proxy_buffers 8 32k;
        proxy_buffer_size 64k;	
    }
}
