[英]ActionCable Rails 5 (Passenger) - failed: Error during WebSocket handshake: Unexpected response code: 404
I am trying to deploy ActionCable and Rails 5 To Production server (DigitalOcean). 我正在尝试将ActionCable和Rails 5部署到生产服务器(DigitalOcean)。 I have followed all steps mention in the Gorails video here: https://gorails.com/episodes/deploy-actioncable-and-rails-5
我已按照Gorails视频中提到的所有步骤进行操作: https ://gorails.com/episodes/deploy-actioncable-and-rails-5
The app was deployed using Phusion Passenger + Nginx + Capistrano. 该应用程序使用Phusion Passenger + Nginx + Capistrano进行部署。
And when I tried to checked my site on production, I got this error on the browser's console: 当我尝试在生产中检查我的网站时,我在浏览器的控制台上收到了此错误:
WebSocket connection to 'ws://139.59.175.34/cable' failed: Error during WebSocket handshake: Unexpected response code: 404
These are my settings: 这些是我的设置:
/etc/nginx/sites-enabled/default 在/ etc / nginx的/启用的站点- /默认
server {
listen 80;
listen [::]:80 ipv6only=on;
server_name my_server_domain;
passenger_enabled on;
rails_env production;
root /home/deploy/my_app_domain/current/public;
# ActionCabel config (disable this if u r not using it)
location /cable {
passenger_app_group_name actioncable_websocket;
passenger_force_max_concurrent_requests_per_process 0;
}
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
production.rb production.rb
config.action_cable.url = "/cable"
config.action_cable.allowed_request_origins = ["http://139.59.175.34"]
cable.js cable.js
(function() {
this.App || (this.App = {});
App.cable = ActionCable.createConsumer("/cable");
}).call(this);
I have tried to change the ActionCable config on config/production.rb
to: 我试图将
config/production.rb
上的ActionCable配置更改为:
config.action_cable.url = [/ws:\/\/*/, /wss:\/\/*/]
config.action_cable.allowed_request_origins = [/http:\/\/*/, /https:\/\/*/]
but still no luck. 但仍然没有运气。
I have also looked into the production.log on the server and this is the error that was recorded: 我也查看了服务器上的production.log,这是记录的错误:
WebSocket error occurred: One or more reserved bits are on: reserved1 = 1, reserved2 = 0, reserved3 = 0
UPDATE: 更新:
Below is firewall setting on the server: 以下是服务器上的防火墙设置:
Your configuration looks correct. 您的配置看起来正确。
This issue can happens if you have a firewall running. 如果您正在运行防火墙,则会发生此问题。
Check with your iptables configuration (linux) if something is blocking it (I don't have a specific line of code to give to you though). 检查你的iptables配置(linux)是否阻塞了它(虽然我没有特定的代码行)。
If you're on Windows, check that there are no "antivirus" or "firewall" intercepting / blocking the bits. 如果您使用的是Windows,请检查是否有“防病毒”或“防火墙”拦截/阻止这些位。 I heard that Node32 is a very good candidate to block websockets.
我听说Node32是阻止websockets的非常好的候选者。
Update: Can you also try to connect using wss://139.59.175.34/cable
instead of ws://139.59.175.34/cable
? 更新:您还可以尝试使用
wss://139.59.175.34/cable
而不是ws://139.59.175.34/cable
进行连接吗? (Be sure your NGinx is proxying with SSL). (确保您的NGinx使用SSL代理)。 https://docs.nginx.com/nginx/admin-guide/security-controls/securing-http-traffic-upstream/

Finally I found the answer to my problem. 最后我找到了问题的答案。 It turns out that I do not have redis installed on my production server.
事实证明我的生产服务器上没有安装redis。 So I just need to install redis and now everything works great!
所以我只需要安装redis,现在一切都很棒!
To check whether you have redis installed on the server or not, use this command: 要检查服务器上是否安装了redis,请使用以下命令:
redis-cli
If the redis console appear, then you're all set. 如果出现redis控制台,那么你已经完成了设置。 If an error/warning comes out, you can follow these steps to install and run redis:
如果出现错误/警告,您可以按照以下步骤安装并运行redis:
sudo apt install redis-server
redis-server
Hope it helps! 希望能帮助到你!
