我已经在这个问题上挣扎了好几天,终于到了一堵砖墙。
我一直试图让我的筹码运行:
我一直在看其他一些SO这样的文章:
nginx - uWSGI HTTP + websocket config
他们似乎遇到了类似的问题,但解决方案对我不起作用。
基本上,每当我尝试启动uWSGI进程时,我都会遇到nginx 502坏网关屏幕。根据文档中的说明,我有两个单独的uwsgi进程在运行。
当我运行websocket uwsgi实例时,我得到以下内容:
*** running gevent loop engine [addr:0x487690] ***
[2015-05-27 00:45:34,119 wsgi_server] DEBUG: Subscribed to channels: subscribe-broadcast, publish-broadcast
告诉我那个uwsgi实例运行正常。 然后我运行我的下一个uwsgi进程并且没有错误记录那里......
当我导航到浏览器中的页面时,页面会挂起几秒钟,然后才能获得502 Bad Gateway屏幕。
根据NGINX日志,NGINX说:
2015/05/26 22:46:08 [error] 18044#0: *3855 upstream prematurely closed connection while reading response header from upstream, client: 192.168.59.3, server: , request: "GET /chat/ HTTP/1.1", upstream: "uwsgi://unix:/opt/django/django.sock:", host: "192.168.59.103:32768"
这是我尝试在网络浏览器中访问该页面时唯一的错误日志。
任何人的想法???
以下是我的部分配置文件:
nginx.conf
user www-data;
worker_processes 4;
pid /run/nginx.pid;
events {
worker_connections 768;
}
http {
##
# Basic Settings

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/django.conf;
}
我有以下django.conf文件,它扩展了nginx.conf
upstream django {
server unix:/opt/django/django.sock;
}
server {
listen 80 default_server;
charset utf-8;
client_max_body_size 20M;
sendfile on;
keepalive_timeout 0;
large_client_header_buffers 8 32k;
location /media {
alias /opt/django/app/media/media;
}
location /static {
alias /opt/django/app/static;
}
location / {
include /opt/django/uwsgi_params;
}
location /ws/ {
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://unix:/opt/django/app.sock;
proxy_buffers 8 32k;
proxy_buffer_size 64k;
}
}
两个负责我的uwsgi进程的文件如下:
runserver_uwsgi.ini:
[uwsgi]
ini = :runserver
[default]
userhome = /opt/django
chdir = %dapp/
master = true
module = chatserver.wsgi:application
no-orphans = true
threads = 1
env = DJANGO_SETTINGS_MODULE=myapp.settings
vacuum = true
[runserver]
ini = :default
socket = /opt/django/app.sock
module = wsgi_django
buffer-size = 32768
processes = 4
chmod-socket=666
和wsserver_uwsgi.ini
[uwsgi]
ini = :wsserver
[default]
userhome = /opt/django
chdir = %dapp/
master = true
module = chatserver.wsgi:application
no-orphans = true
threads = 1
env = DJANGO_SETTINGS_MODULE=chatserver.settings
vacuum = true
[wsserver]
ini = :default
http-socket = /opt/django/django.sock
module = wsgi_websocket
http-websockets = true
processes = 2
gevent = 1000
chmod-socket=666

我发现了这个问题。
我的[runserver]套接字(app.sock)应该指向upstream django
,我的[wsserver]套接字(django.sock)应该指向location /ws/
,如下所示:
upstream django {
server unix:/opt/django/app.sock;
}
server {
listen 80 default_server;
charset utf-8;
client_max_body_size 20M;
sendfile on;
keepalive_timeout 0;
large_client_header_buffers 8 32k;
location /media {
alias /opt/django/app/media/media;
}
location /static {
alias /opt/django/app/static;
}
location / {
include /opt/django/uwsgi_params;
}
location /ws/ {
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://unix:/opt/django/django.sock;
proxy_buffers 8 32k;
proxy_buffer_size 64k;
}
}

我有同样的问题,但这不是我的NGINX配置,这是我的UWSGI进程在我将JSON从客户端发布到服务器时导致超时错误。我的流程为5,将其更改为1,这样就解决了问题。对于我的应用程序,我只需要一次运行一个进程,因为AWS不需要被多个进程超载。
这是工作的UWSGI配置ini文件,它解决了超时问题,从而解决了502网关问题。
autoboot.ini
#!/bin/bash
[uwsgi]
socket = /tmp/app.sock
master = true
chmod-socket = 660
module = app.wsgi
chdir = home/app
close-on-exec = true # Allow linux shell via uWSGI
processes = 1
threads = 2
vacuum = true
die-on-term = true
这也是我的Nginx配置。
nginx.conf
# the upstream component nginx needs to connect to
upstream django {
server unix:///app/tmp/app.sock; # for a file socket
# server 127.0.0.1:6000; # 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 XXX.XXX.XX.X #actual IP in here
charset utf-8;
# max upload size
client_max_body_size 75M; # adjust to taste
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
# Finally, send all non-media requests to the Django server.
location / {
uwsgi_pass django;
include uwsgi_params;
}
location /static {
autoindex on;
alias app/static; # your Django project's static files - amend as required
}
error_page 502 /502.html;
location = /502.html {
alias app/templates/502autoreload.html;
}
client_body_timeout 100s;
uwsgi_read_timeout 500s;
keepalive_timeout 300;
}
