【问题描述】：
我已经安装了 Ruby/Rails/Apache2/Passenger，我使用 Capitrano 来部署我的 Rails 应用程序。
但是，当我部署时（没有错误显示），我访问我的网站，它记录了一些错误，后来我通过passenger-config --detect-apache2 命令在Apache2 log 中得到错误内容。
$ passenger-config --detect-apache2

Permission problems
Sorry, this program doesn't have enough permissions to autodetect all your
Apache installations, because it's running as the cenx user.
Please re-run this program with root privileges:
export ORIG_PATH="$PATH"
sudo -s -E
export PATH="$ORIG_PATH"

希望你能帮助我，谢谢！

看起来Passenger 找不到Apache。查看ruby-forum.com/topic/4411223
