[英]WebSockets with nginx and puma (websocket-rails)
Using the websocket-rails gem, I'm able to successfully get a websocket connection straight through puma in development, however, when deployed to production and attempting to access the websocket through nginx (passing off to puma) I have a couple of errors: one in the nginx error log: 使用websocket-rails gem,我可以在开发过程中直接通过puma成功地获得websocket连接,但是,当部署到生产环境并尝试通过nginx访问websocket(传递给puma)时,我会遇到两个错误: Nginx错误日志中的一个:
[info] 14340#0: *7 upstream timed out (110: Connection
timed out) while proxying upgraded connection, client: 123.45.67.89, server:
foo.com, request: "GET /websocket HTTP/1.1", upstream:
"http://unix:///opt/oneconnect/shared/tmp/sockets/puma.sock:/websocket", host:
"foo.com"
... and one on the javascript console: ...,然后在javascript控制台上:
WebSocket connection to 'ws://foo.com/websocket' failed: Error during WebSocket handshake: Unexpected response code: 301
I found that nginx (the version I'm using is 1.4.6) is capable of websocket use but requires special configuration , which I've already attemped (getting the errors above). 我发现nginx(我正在使用的版本是1.4.6)可以使用websocket,但需要进行特殊配置 (我已经尝试过了)(获取上面的错误)。 Here's my nginx.conf:
这是我的nginx.conf:
upstream oneconnect {
server unix:///opt/oneconnect/shared/tmp/sockets/puma.sock;
}
server {
listen 80;
listen 443 ssl;
#ssl on;
ssl_certificate /etc/ssl/foo.com.crt;
ssl_certificate_key /etc/ssl/foo.com.key;
root /opt/oneconnect/current/public;
try_files $uri @oneconnect;
access_log /opt/oneconnect/current/log/nginx.access.log;
error_log /opt/oneconnect/current/log/nginx.error.log info;
server_name foo.com;
location ~ ^/(assets)/ {
root /opt/oneconnect/current/public;
gzip_static on;
expires max;
add_header Cache-Control public;
}
location /websocket/ {
proxy_pass http://oneconnect;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
location @oneconnect {
proxy_read_timeout 300;
proxy_connect_timeout 300;
proxy_redirect off;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://oneconnect;
}
}
I'm assuming that I'm missing something simple, but I'm stumped at this point and have Googled until my eyes started bleeding. 我以为我错过了一些简单的东西,但此时我很迷and,并且一直用Google搜索,直到我的眼睛开始流血为止。 If anyone could help it would be much appreciated, or maybe just point me to how to debug these connections (it seems hard to get debug info from a ws connection).
如果有人可以提供帮助,将不胜感激,或者只是将我指向如何调试这些连接(似乎很难从ws连接中获取调试信息)。 Thanks for your time.
谢谢你的时间。
