sudo unicorn -c unicorn.rb -E development -D -l 0.0.0.0:8080

我在Unicorn日志中收到以下错误.

I,[2013-05-05T19:15:15.538805 #2357]  INFO -- : listening on addr=0.0.0.0:8080 fd=5
F,[2013-05-05T19:15:15.541673 #2357] FATAL -- : error adding listener addr=/home/vagrant/tmp/myapp/sockets/unicorn.sock

我以流浪者用户身份登录,并按照http://recipes.sinatrarb.com/p/deployment/nginx_proxied_to_unicorn配置了unicorn.rb

@dir = '/home/vagrant/myapp/'

worker_processes 4
working_directory @dir

timeout 30

listen "#{@dir}tmp/sockets/unicorn.sock",:backlog => 64
pid "#{@dir}tmp/pids/unicorn.pid"

stderr_path "#{@dir}log/unicorn.stderr.log"
stdout_path "#{@dir}log/unicorn.stdout.log"

我查看了代码,但无法初始化以下内容

Kgio::UNIXServer.new('0.0.0.0:8080')
