Unicorn和nginx错误

Question

vagrant@lucid32:/vagrant$ bundle exec unicorn_rails -c config/unicorn.rb -D -d
{:unicorn_options=>{:listeners=>[], :config_file=>"config/unicorn.rb"},
 :app=>
  #<Proc:0xa1a6ef4@/home/vagrant/.rbenv/versions/1.9.3-p392/lib/ruby/gems/1.9.1/gems/unicorn-4.6.2/bin/unicorn_rails:135 (lambda)>,
 :daemonize=>true}

master failed to start, check stderr log for details

不幸的是，我不知道如何检查stderr日志，culd找不到任何相关信息。

下面是配置文件：

working_directory "/vagrant"
pid "/vagrant/tmp/pids/unicorn.pid"
stderr_path "/vagrant/log/unicorn.log"
stdout_path "/vagrant/log/unicorn.log"

listen "/tmp/unicorn.todo.sock"
worker_processes 2
timeout 30

这是nginx.conf文件

upstream unicorn {
  server unix:/tmp/unicorn.todo.sock fail_timeout=0;
}


server {
  listen 80 default;
  # server_name example.com;
  root /vagrant/public;
  try_files $uri/index.html $uri @unicorn;
  location @unicorn {
      proxy_pass  http://unicorn;
  }

  error_page 500 502 503 504 /500.html;
}

现在的问题是没有创建/tmp目录。所以我创建了它，得到了同样的错误，然后我删除了它，得到了同样的错误。现在我陷入了一个无限循环中。

我非常感谢任何关于ho的帮助，让它工作，或者至少如何读取错误日志。

编辑:我找到了stderr文件：

Answer 1

独角兽进程正在后台运行(-d)，请在终端上键入以下命令

ps aux | grep unicorn

并杀死正在运行的独角兽进程，然后重新启动独角兽进程。

Answer 2

我也遇到了同样的问题( Text file busy错误)，也是从Vagrant VM运行的。@destiel的评论帮助我解决了这个问题:显然，这是由于从Vagrant共享文件夹运行rails和unicorn造成的。在复制到虚拟驱动器后，它工作正常。我在Windows8主机上运行，以防万一。
