It looks like the unicorn-railsgem that @Dogbert mentioned can actually be used to make Unicorn the rails serverhandler.
看起来unicorn-rails@Dogbert 提到的gem 实际上可以用来使 Unicorn 成为rails server处理程序。
Simply include gem "unicorn-rails"(and for Rails 4.2.4, gem "rack-handlers") in your Gemfile, run bundle installto install the gem, then you can run:
只需在您的, 运行中包含gem "unicorn-rails"（对于 Rails 4.2.4，gem "rack-handlers"）以安装 gem，然后您可以运行：Gemfilebundle install
$ rails server unicorn
Although once unicorn-railsis installed, Unicorn should be the default app server so you could also just run rails serverand it should use Unicorn (assuming you don't also have Thin or Mongrel in your Gemfile, in which case they may conflict and you might want to remove the ones you're not using).
虽然一旦unicorn-rails安装，Unicorn 应该是默认的应用程序服务器，所以你也可以直接运行rails server，它应该使用 Unicorn（假设你Gemfile的 .那些你没有使用的）。

A better option might just be to run the unicorn server directly.
更好的选择可能只是直接运行 unicorn 服务器。
bundle exec unicorn -p 3000 # default port is 8080
回答by Tom Maeckelberghe
gem 'rack-handlers'
rails server unicorn

However the answer by Stevenis the simplest way to do.
然而，答案Steven是最简单的方法。
I run unicornon development environment via a rake task:
我unicorn通过 rake 任务在开发环境中运行：
lib/tasks/dev_unicorn.rake:
lib/tasks/dev_unicorn.rake:
task :server do
# optional port parameter
port = ENV['PORT'] ? ENV['PORT'] : '3000'
puts 'start unicorn development'
# execute unicorn command specifically in development
# port at 3000 if unspecified
sh "cd #{Rails.root} && RAILS_ENV=development unicorn -p #{port}"
end
# an alias task
task :s => :server
run:
跑：
rake s

I don't think it is possible to use unicorn as 'rails s'. Use this -
我认为不可能将独角兽用作“rails”。用这个 -
Add gem 'unicorn' to gem file and run bundle install.
将 gem 'unicorn' 添加到 gem 文件并运行 bundle install。
and then run any of the following commands -
然后运行以下任何命令 -
$ unicorn -p 3000
$ 独角兽 -p 3000
or
或者
$ unicorn_rails -p 3000
$ unicorn_rails -p 3000
