我想部署我的Ruby on Rails应用程序与ArchLinux的Linode VPS，我使用Apache作为Web服务器。乘客：红宝石（机架）应用程序无法启动
这里是客运错误：
Error message: No such file or directory - config.ru
Exception class: Errno::ENOENT
Application root: /srv/http
这里是回溯：

官方旅客指南（4.3。部署到一个子URI）我创建了一个符号链接到我的应用程序：
$ ls -la /srv/http
total 197580
drwxr-xr-x 7 root root 4096 Oct 25 13:07 .
drwxr-xr-x 4 root root 4096 Jul 7 14:23 ..
drwxrwxr-x 4 mylinode root 4096 Oct 1 18:40 copisteria
lrwxrwxrwx 1 root root 35 Oct 25 13:07 copy -> /srv/http/copisteria/current/public
-rw-r--r-- 1 root root 972 Aug 8 18:48 index.html
我认为问题出在Application Root，那应该是/srv/http/copisteria/current。
是的，这是问题......现在我有'RackBaseURI/copy'，并且一切正常。谢谢！ – enricostn
