问题描述:在使用ActionCable + Nginx + Puma时,遇到了java.io.EOFException错误。
解决方法:
location /cable {
proxy_pass http://puma_server;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Forwarded-Ssl on;
proxy_set_header X-Forwarded-Port $server_port;
}
# config/puma.rb
workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['RAILS_MAX_THREADS'] || 5)
threads threads_count, threads_count

environment ENV['RACK_ENV'] || 'development'
# Add this line to enable WebSocket proxying
on_worker_boot do
ActiveSupport.on_load(:active_record) do
ActiveRecord::Base.establish_connection
end
end
development:
adapter: redis
url: redis://localhost:6379/1
test:
adapter: async
production:
adapter: redis
url: <%= ENV['REDIS_URL'] %>
检查Redis是否正常工作。确保Redis服务器正在运行,并且连接信息正确。
检查服务器日志以获取更详细的错误信息。在服务器上运行应用程序时,查看Nginx、Puma和Rails应用程序的日志文件,以获取更多关于错误的详细信息。
希望这些解决方法可以帮助你解决ActionCable + Nginx + Puma和java.io.EOFException的问题。如果问题仍然存在,请进一步检查网络连接和服务器配置。
