Question

就像我在标题中所写的，Unicorn主进程最近（在部署和重新启动之后）正在杀死工作者并且一直在开始新的工作，这就是为什么我的Rails应用程序根本不起作用的原因。除此之外，服务器上的CPU是100％。但是，如果我制作上限独角兽：停止正在关闭正确关闭但是在独角兽上限之后：开始它再次重新开始。

unicorn.rb：

# Should be 'production' by default, otherwise use other env 
rails_env = ENV['RAILS_ENV'] || 'production'

app_path = "/home/ruby/app/current"

listen 5000
# Spawn unicorn master worker for user ruby (group: www-data)
user 'ruby', 'ruby'
working_directory app_path

worker_processes 2
timeout 90
#preload_app true

# Log everything to one file
stderr_path "log/unicorn.log"
stdout_path "log/unicorn.log"

# Set master PID location
pid "#{app_path}/tmp/pids/unicorn.pid"

# To save some memory and improve performance
GC.respond_to?(:copy_on_write_friendly=) and GC.copy_on_write_friendly = true

# Force the bundler gemfile environment variable to   
# reference the Сapistrano "current" symlink
before_exec do |_|
   ENV["BUNDLE_GEMFILE"] = File.join(@app, 'Gemfile')
end

before_fork do |server, worker|
 # Replace with MongoDB or whatever
 if defined?(ActiveRecord::Base)
    ActiveRecord::Base.connection.disconnect!
    Rails.logger.info('Disconnected from ActiveRecord')
 end

 old_pid = "#{server.config[: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

  sleep 1
end

after_fork do |server, worker|
  # Replace with MongoDB or whatever
  if defined?(ActiveRecord::Base)
    ActiveRecord::Base.establish_connection
    Rails.logger.info('Connected to ActiveRecord')
  end
