这是我在服务器故障的第一个问题。 searchnetworking时找不到解决scheme。
我正在运行一个运行Nginx的OpenBSD服务器，我没有设置，这是在浏览器中抛出一个502错误的网关错误。 Nginx错误日志显示这个错误：

我对Nginx很less有经验。 任何帮助是极大的赞赏。
附加信息：
unicorn.rb
listen '/tmp/unicorn.sock' worker_processes 2 working_directory "/var/sfta/current" pid "/var/run/unicorn.pid" stderr_path "/var/log/unicorn.log" timeout 120 preload_app true before_fork do |server, worker| defined?(ActiveRecord::Base) and ActiveRecord::Base.connection.disconnect! old_pid = '/var/run/unicorn.pid.oldbin' if File.exists?(old_pid) && server.pid != old_pid begin Process.kill("QUIT", File.read(old_pid).to_i) rescue Errno::ENOENT, Errno::ESRCH # someone else did our job for us end end # Throttle the master from forking too quickly by sleeping. sleep 1 end after_fork do |server,worker| defined?(ActiveRecord::Base) and ActiveRecord::Base.establish_connection worker.user('_sfta', '_sfta') if Process.euid == 0 end
这意味着Nginx会尝试使用UNIX套接字/tmp/unicorn.sock将您的stream发送到应用程序。 但似乎这个套接字不存在。
独angular兽是一个Ruby服务器。 你需要启动你ruby应用程序与独angular兽指定sockets/ tmp / unicorn.sock。
