独角兽开始冻结

我正在做一些故障排除，以弄清为什么我的网站无法加载。

我正在使用Amazon OopsWorks。我有一台运行Rails 4.2.0和Ruby 2.2.0的Amazon Linux服务器。我正在使用Nginx和Unicorn。我已验证Nginx正在运行。当我尝试启动Unicorn时，bundle exec unicorn -E production -c /srv/www/likeminds/current/config/unicorn.rb没有出现错误。我什么也没得到。这就是问题，什么都没有发生。

独角兽怎么了？似乎一开始就冻结了。先谢谢您的帮助。

这是我的服务器上正在运行的内容。

更新我的Unicorn.rb文件不起作用。现在EC2输出

/home/deploy/.bundler/likeminds/ruby/2.2.0/gems/unicorn-4.9.0/lib/unicorn/configurator.rb:657:in `parse_rackup_file': rackup file (config.ru) not readable (ArgumentError)

这是导致Unicorn冻结的Unicorn.rb

# Set the working application directory
# working_directory "/path/to/your/app"
working_directory "/srv/www/likeminds/current/"

# Unicorn PID file location
# pid "/path/to/pids/unicorn.pid"
pid "/srv/www/likeminds/shared/pids/unicorn.pid"

# Path to logs
# stderr_path "/path/to/log/unicorn.log"
# stdout_path "/path/to/log/unicorn.log"
stderr_path "/srv/www/likeminds/shared/log/unicorn.log"
stdout_path "/srv/www/likeminds/shared/log/unicorn.log"

# Unicorn socket
listen "/srv/www/likeminds/shared/sockets/unicorn.likeminds.sock"
listen "/srv/www/likeminds/shared/sockets/unicorn.likeminds.sock"

# Number of processes
# worker_processes 4
worker_processes 2

# Time-out
timeout 30

这是一个输出错误但在我的本地主机上成功运行的版本。

if ENV["RAILS_ENV"] == "development"
  worker_processes 1
else
  worker_processes 3
end

timeout 30

更新＃＃

更改权限后，我能够启动Unicorn。但是我收到错误。
