我有一个在 nginx 上运行的 Django 应用程序。这个应用程序使用套接字，(据我所知)应该被代理。所以我在配置 nginx 和其他东西时遇到了麻烦。相同的应用程序在 Apache/2.4.7 上运行良好，因此我认为这不是编程错误。
使用的套接字基于 Django-Channels，后端与 Channels getting started 中的代码非常相似.
对于服务器配置，我使用了 this手册。
一开始我只有一个问题:在创建套接字时我得到了 200 个请求应答而不是 101 个。经过多次操作(配置和安装更新版本)和信息收集后，我得出了目前的情况:
我为套接字单独启动 uwsgi:
uwsgi --virtualenv /home/appname/env/ --http-socket /var/run/redis/redis.sock --http-websock --wsgi-file /home/appname/appname/appname/wsgi.py
在创建套接字的这一步 var socket = new WebSocket("ws://appname.ch/ws/64"); 我明白了
WebSocket connection to 'ws://appname.ch/ws/64' failed: Error during WebSocket handshake: Unexpected response code: 502
当然
2016/09/12 12:00:26 [crit] 30070#0: *2141 connect() to unix:/var/run/redis/redis.sock failed (13: Permission denied) while connecting to upstream, client: 140.70.82.220, server: appname.ch,, request: "GET /ws/64 HTTP/1.1", upstream: "http://unix:/var/run/redis/redis.sock:/ws/64", host: "appname.ch"
在 nginx 错误日志中。
在 chmod 777/var/run/redis/redis.sock 之后我得到响应
WebSocket connection to 'ws://appname.ch/ws/64' failed: Error during WebSocket handshake: Unexpected response code: 404
在 uwsgi 中

似乎 404 应该不是一个复杂的错误，但经过多天的修复后，我不知道问题出在哪里，也不知道我的方法是否正确。
最佳答案
首先，永远不要尝试手动创建 socks 。 只需设置一个路径，它就会自动创建。
这是 nginx 和 uwsgi conf 的示例:
server {
root /your/djang/app/main/folder/;
# the port your site will be served on
listen 80;
server_name your-domain.com *.your-domain.com # if you have subdomains
charset utf-8;
access_log /path/to/logs/if/you/have/access_log.log
error_log /path/to/logs/if/you/have/error_log.log
# max upload size
client_max_body_size 1G;
location /media/ {
alias /path/to/django/media/if/exist/;
}
location /static/ {
alias /path/to/django/static/if/exist/;
}
# Note three slash
location / {
uwsgi_pass unix:///home/path/to/sock/file/your-sock.sock
}
这个cna就是你的uwsgi配置文件
# suprasl_uwsgi.ini file
[uwsgi]
uid = www-data
gid = www-data
chmod-socket = 755
chown-socket = www-data
# Django-related settings
# the base directory (full path)
chdir = /your/djang/app/main/folder/
# Django's wsgi file
wsgi-file = /your/djang/app/main/folder/main-folder/wsgi.py;
# the virtualenv (full path)
home = /your/env/folder/;
# process-related settings
# master
master = true
# maximum number of worker processes
processes = 2
# the socket (use the full path to be safe
socket = /home/path/to/sock/file/your-sock.soc
logto = /path/to/logs/if/you/have/uwsgi_logs.log
你所要做的就是运行这个命令:
uwsgi --ini your_uwsgi_file.ini # --ini 选项用于指定一个文件
