AWSのAmazon Linuxにrails+nginx+unicornの流行りの構成を乗っけようとした。

した。

/usr/local/lib/ruby/gems/2.2.0/gems/unicorn-4.9.0/lib/unicorn/socket_helper.rb見てみます。

    sock = if address[0] == ?/
        if File.exist?(address)
          if File.socket?(address)
            begin
              UNIXSocket.new(address).close
              # fall through, try to bind(2) and fail with EADDRINUSE
              # (or succeed from a small race condition we can't sanely avoid).
            rescue Errno::ECONNREFUSED
              logger.info "unlinking existing socket=#{address}"
              File.unlink(address)
            end
          else
            raise ArgumentError,
                  "socket=#{address} specified but it is not a socket!"
          end
        end

if File.exist?(address)内を見ると、

          else
            raise ArgumentError,
                  "socket=#{address} specified but it is not a socket!"
          end

つまりunicorn.sockはソケットファイルと認識されていないのか。

unicorn.sockを削除したらいけるみたい。
