我的rails应用程序在我的用户下运行良好:
$ rails server
=> Booting WEBrick
=> Rails 3.0.5 application starting in development on htttp://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
[2011-03-30 01:56:29] INFO WEBrick 1.3.1
[2011-03-30 01:56:29] INFO ruby 1.9.2 (2011-02-18) [x86_64-darwin10.7.0]
[2011-03-30 01:56:29] INFO WEBrick::HTTPServer#start: pid=3899 port=3000
但我需要在端口80下运行它,所以运行它作为sudo给了我这个:
$ sudo rails server -p 80
