使用config/ unicorn /unicorn.rb配置更改unicorn的默认端口号

Question

如何使用config/unicorn/unicorn.rb文件配置参数更改unicorn的默认端口号。我需要在同一台机器上运行两个nginx的独角兽，如何实现？现在，我收到端口地址已被占用错误。

app_dir = "/home/rails/apps/app_name/current"
shared_dir = "/home/rails/apps/app_name/shared"

env = "staging"

# Set unicorn options
worker_processes 1
preload_app true
timeout 30

# Fill path to your app
working_directory app_dir

# Set up socket location
listen "#{shared_dir}/sockets/unicorn.admin.sock", :backlog => 64

# Loging
stderr_path "#{shared_dir}/log/unicorn.stderr.log"
stdout_path "#{shared_dir}/log/unicorn.stdout.log"

# Set master PID location
pid "#{shared_dir}/pids/unicorn.admin.pid"

before_fork do |server, worker|
  # server.listen(addr, :tries => -1, :delay => 5, :tcp_nopush => true)
  defined?(ActiveRecord::Base) and ActiveRecord::Base.connection.disconnect!
  old_pid = "#{server.config[:pid]}.oldbin"
  if File.exists?(old_pid) && server.pid != old_pid
    begin
      sig = (worker.nr + 1) >= server.worker_processes ? :QUIT : :TTOU
      Process.kill(sig, File.read(old_pid).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
      # someone else did our job for us
    end
  end
end

after_fork do |server, worker|
  defined?(ActiveRecord::Base) and ActiveRecord::Base.establish_connection
end

before_exec do |server|
  ENV['BUNDLE_GEMFILE'] = "#{app_dir}/Gemfile"
end

我得到了这个错误：

/shared/sockets/unicorn.admin.sock (Errno::EADDRINUSE)

看起来您使用的是套接字连接。在这种情况下，您必须对该行使用uniq条目：

# Set up socket location
listen "#{shared_dir}/sockets/unicorn<X>.admin.sock", :backlog => 64
