我发现了问题。
我的[runserver]套接字（app.sock）应该指向下面
upstreamdjango，我的[wsserver]套接字（django.sock）应该指向下面
location /ws/：
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; }}
