ruby-on-rails - 500 内部服务器错误与 Rails 生产

Question

我最近将一些新文件上传到我的生产服务器(并覆盖了旧文件)，现在收到 500 Internal Server Error。服务器正在运行 phusion passenger(即使我不再收到该错误消息)并且在我的本地测试环境中一切似乎都运行良好。

这是网站:http://www.pandonews.com/

当我查看我的 apache 日志时，我看到了这个错误:

[ pid=3106 thr=140057117177664 file=ext/apache2/Hooks.cpp:884 time=2013-09-01 17:37:24.84 ]: Unexpected error in mod_passenger: Cannot spawn application '/var/www/feedme': The spawn server died unexpectedly, and restarting it failed.
  Backtrace:
     in 'virtual Passenger::SessionPtr Passenger::ApplicationPool::Client::get(const Passenger::PoolOptions&)' (Client.h:742)
     in 'Passenger::SessionPtr Hooks::getSession(const Passenger::PoolOptions&)' (Hooks.cpp:312)
     in 'int Hooks::handleRequest(request_rec*)' (Hooks.cpp:585)

我不知道问题出在哪里。到目前为止，它一直运行良好。我真的不知道从哪里开始才能解决这个问题。我尝试再次运行 gem passenger install 但没有任何反应。

最近的事件:

• 已安装 pg gem(但在决定暂时使用 sqlite3 后将其从 gem 文件中删除)yml 文件应该没问题...
• 尝试在服务器和本地运行 bundle update，但它一直挂起
• 更改了一些 javascript 和 css 文件...
• 尝试使用 RAILS_ENV=production rake:db reset 重置服务器 - 没有变化!

编辑:运行 rails s production 时出现以下错误:

编辑 2:

$ passenger-status
ERROR: Phusion Passenger doesn't seem to be running.

编辑 3:看起来它正在运行，仍然是内部服务器错误:

passenger start -a 0.0.0.0 -p 3000 -d -e production

Answer 1

做了以下事情:

1. gem install passenger(没有 sudo 或任何东西)
2. 找到root:passenger-config –root
3. 将 chmod 提供给所有从根目录到用户名的文件夹:sudo chmod -R 777/home/username/.rvm/gems/ruby-1.9.3-p392/gems/passenger-4.0.14 到每个文件夹直到/home/用户名/
4. passenger-install-apache2-module(没有任何东西)
5. 将给定的代码粘贴到里面:/etc/apache2/httpd.conf
6. sudo 服务 apache2 重启
