我如何使用独角兽作为“rails"? [英] How can I use unicorn as "rails s"?

问题描述

一个新的 Rails 项目的 Gemfile 显示:

A new Rails project's Gemfile shows:

# Use unicorn as the app server
gem 'unicorn'

rails s --help 显示:

Usage: rails server [mongrel, thin, etc] [options]

然而，正在做:

rails s unicorn

我明白了:

/Users/patrick/.rvm/gems/ruby-1.9.3-head@keynote/gems/rack-1.4.5/lib/rack/handler.rb:63:in `require': cannot load such file -- rack/handler/unicorn (LoadError)

from script/rails:6:in `require'
from script/rails:6:in `<main>'

我过去在其他项目中使用过 unicorn，但总是不得不运行 unicorn 命令并指定一个配置文件，这有点麻烦.我想知道如何通过使用 rails s...

I've used unicorn in the past on other projects, but always had to run the unicorn command and specify a config file which is a bit of a pain. I am wondering how I can just simply make it work by using rails s...

这可能吗?

推荐答案

它看起来像 unicorn-rails @Dogbert 提到的 gem 实际上可以用来使 Unicorn 成为 rails server 处理程序.

It looks like the unicorn-rails gem that @Dogbert mentioned can actually be used to make Unicorn the rails server handler.

只需在 Gemfile 中包含 gem "unicorn-rails"(对于 Rails 4.2.4，gem "rack-handlers"), 运行 bundle install 安装 gem，然后可以运行:

Simply include gem "unicorn-rails" (and for Rails 4.2.4, gem "rack-handlers") in your Gemfile, run bundle install to install the gem, then you can run:

$ rails server unicorn

虽然一旦安装了 unicorn-rails，Unicorn 应该是默认的应用服务器，所以你也可以只运行 rails server 并且它应该使用 Unicorn(假设你不t 在您的 Gemfile 中也有 Thin 或 Mongrel，在这种情况下，它们可能会发生冲突，您可能希望删除您不使用的那些).

Although once unicorn-rails is installed, Unicorn should be the default app server so you could also just run rails server and 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).
