启动 Rails Passenger App 时出错

Question

我使用 RVM 将 ruby 版本更改为 2.1.5，使用 Apache 配置了 4 rails 应用程序，但我无法使用 Passenger 启动它们。所以我每次都遇到这个错误。

App 8612 stderr: Cannot execute "/root/.rvm/gems/ruby-2.1.5/gems/passenger-5.0.8/buildout/support-binaries/PassengerAgent": Permission denied (errno=13)
[ 2015-06-01 20:11:43.2847 8422/7f244835b700 App/Implementation.cpp:287 ]: Could not spawn process for application /var/www/example: An error occured while starting up the preloader.

  Message from application: Cannot execute "/root/.rvm/gems/ruby-2.1.5/gems/passenger-5.0.8/buildout/support-binaries/PassengerAgent": Permission denied (errno=13)

我应该如何纠正这种情况？我使用 chown -R 777 /root/.rvm/gems/ruby-2.1.5/gems/passenger-5.0.8/buildout/support-binaries/ ，但问题最后

Answer 1

首先，你不应该运行你的应用程序使用 root 用户。

将 PassengerUserSwitching on 添加到您的虚拟主机。如果您的 Web 应用程序由 root 拥有，它应该能够使用 rvm（因为它仅为 root 用户安装）。
