ubuntu下创建第一个rails应用程序

Posted 2020-09-25 lxjshuju

  一.创建一个新的应用程序

在控制台输入

> rails new  demo

 create  
      create  README.rdoc
      create  Rakefile
      create  config.ru
      create  .gitignore
      create  Gemfile
      create  app
...........
Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.
         run  bundle exec spring binstub --all
* bin/rake: spring inserted
* bin/rails: spring inserted

 demo文件建好了。

二.怎样启动server

>cd demo 到demo目录下

启动本地web服务器 > rails server

=> Booting WEBrick
=> Rails 4.1.1 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server
[2014-06-22 11:11:48] INFO  WEBrick 1.3.1
[2014-06-22 11:11:48] INFO  ruby 2.1.2 (2014-05-08) [x86_64-linux]
[2014-06-22 11:11:48] INFO  WEBrick::HTTPServer#start: pid=5313 port=3000

启动成功

三.通过浏览器訪问server

此时打开浏览器输入URL http://localhost:3000/，假设出现下面界面

OK，成功。
