【问题描述】：
我正在学习 ruby on rails。正在构建一个小应用程序，服务器已断开连接，不会再次连接。
使用：
rails server
我在 app 目录中。（双重，三重检查...）。
连接到服务器有一段时间工作正常，然后就停止了。
我正在使用 Mysql。
Rails 服务器在我正在开发的其他应用程序上可以正常启动。
这些是我的版本：
root@R://# ruby --version
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux]
root@R://# rails -v
Rails 4.2.1
和mysql版本：
+-------------------------+-------------------------+
| Variable_name | Value |
+-------------------------+-------------------------+
| innodb_version | 5.5.43 |
| protocol_version | 10 |
| slave_type_conversions | |
| version | 5.5.43-0ubuntu0.14.04.1 |
| version_comment | (Ubuntu) |
| version_compile_machine | x86_64 |
| version_compile_os | debian-linux-gnu |
+-------------------------+-------------------------+
这是输出
rails server
root@R://home/ruby/Projects/SempleApp# rails server
=> Booting WEBrick
=> Rails 4.2.1 application starting in development on http://localhost:3000
=> Runrails 服务器-hfor more startup options
=> Ctrl-C to shutdown server
Exiting
我的 database.yml 文件设置正常，自从服务器连接后我没有更改它。
我重新启动了 Mysql 服务。重启了终端，重启了整台电脑。。这个应用还是连接不上服务器，其他应用可以。。
我被困住了……在任何地方都找不到答案。帮助...
PS- 这是我在这里的第一个Q。希望我提供了正确的信息。
谢谢
完全错误：

【问题讨论】：
-
当你
rails dbconsole时会发生什么 -
完美进入控制台..
-
能否发布运行时遇到的错误
rails s -
我用完整的错误更新了 Q..
-
在
TweetrWork/config/routes.rb文件中您缺少end关键字，请添加并使用rails s重新启动
