How do I get 'puma' to start, automatically, when I run `rails server` (like Thin does)
提问by Matt Scilipoti
Normally, when you run rails serverit starts Webrick. If you install the 'thin' gem, then 'thin' starts instead. I would like to do the same thing with the 'puma' server.
通常，当您运行rails server它时，它会启动 Webrick。如果您安装“瘦”gem，则改为“瘦”。我想对“美洲狮”服务器做同样的事情。
I see that the startcommand within railties (lib/rails/commands) calls super, but I can't find what the various options for 'super' are. I have also reviewed many references to Rails within 'thin'.
我看到startrailties (lib/rails/commands) 中的命令调用 super，但我找不到“super”的各种选项是什么。我还在“瘦”中查看了许多对 Rails 的引用。
I found a Changelog entry entitled "Added Thin support to script/server. #488 [Bob Klosinski]" from Oct. of 2008, but that code area has changed significantly since that commit (a93ea88c0623b4f65af98c0eb55924c335bb3ac1).
我从 2008 年 10 月发现了一个名为“Added Thin support to script/server.#488 [Bob Klosinski]”的变更日志条目，但自那次提交（a93ea88c0623b4f65af98c0eb55924c335bb3ac1）以来，该代码区域发生了重大变化。
If someone could direct me to the right section of code, that would be very helpful.
如果有人可以将我引导到正确的代码部分，那将非常有帮助。

To make Puma the default, paste this code into script/rails above require 'rails/commands':
要使 Puma 成为默认值，请将此代码粘贴到上面 require 'rails/commands' 的脚本/rails 中：
require 'rack/handler'
Rack::Handler::WEBrick = Rack::Handler.get(:puma)
Puma is the default server now if you use rails s
如果您使用，Puma 现在是默认服务器 rails s
rails s
=> Booting Puma
=> Rails 3.2.12 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Connecting to database specified by database.yml
Puma 1.6.3 starting...
* Min threads: 0, max threads: 16
* Environment: development
* Listening on tcp://0.0.0.0:3000

With Rails 4 you simply have to add the puma-gem to the Gemfile. (Tested with Rails 4.0.2 and Puma 2.6.0)
使用 Rails 4，您只需将 puma-gem 添加到 Gemfile。（使用 Rails 4.0.2 和 Puma 2.6.0 测试）

At least in Rails 4, you just need to add the following to your Gemfile
至少在 Rails 4 中，您只需要将以下内容添加到 Gemfile 中
gem 'puma'
then run 'bundle', and then when you run 'rails server' and Puma will be used.
然后运行'bundle'，然后当你运行'rails server'时，就会使用Puma。
