Ruby on rails 阿帕奇，Centos，乘客问题

环境：

• Centos 6.5
• 64位
• Apache 2.2.15
• ruby 1.9.3p484
• 乘客（4.0.37）

我继续从Apache获得500服务器错误，无法让它显示任何内容。我已经能够使用webrick访问并移动应用程序，因此我相信问题不是实际的应用程序本身

/var/log/httpd/error\u log的输出：

但我一直无法找到基于搜索这些的解决方案

任何帮助都将不胜感激。谢谢

好的。。。启动并运行它。多亏了我

这使它启动并运行，但随后进行更新，以确保在服务器重新启动后不会再次遇到此问题

@卢里克：你说对了一半。在上述修复之后，我得到了一个“没有权限”的用户。我必须将目录chmod到765才能让Passenger/Apache看到它。感谢您的帮助

您能确保您在project dir上的权限正确吗？那个apache用户有r_x访问权限？仔细检查，没有骰子。我建议使用不同版本的passenger gem（可能有更新？）并重新安装apache模块（并重新配置conf文件以指向模块的新路径）
