我在Linux下安装乘客有问题。 我要这样做的方式是
已添加存储库：deb https://oss-binaries.phusionpassenger.com/apt/passenger trusty main至/etc/apt/sources.list.d/passenger.list
已安装：
sudo apt-get install libapache2-mod-passenger

sudo a2enmod passenger启用乘客模块，但出于某种原因，我在安装后错过了/etc/apache2/mods-available/passenger.conf和/etc/apache2/mods-available/passenger.load个文件。 （它们不会被创建，也不会被libapache2-mod-passenger删除，所以我认为这是某种错误）。所以我手动创建了它们：取值
set@set:~$ which ruby
/home/set/.rvm/rubies/ruby-2.1.5/bin/ruby
set@set:~$ which rails

所以我坚持这一点，不知道在哪里移动nex。重新安装libapache2-mod-passenger无济于事。我该如何解决这个问题？

这个问题更像是记忆问题 我面临着与你的问题类似的问题。但是我的情况正在发生在VM框的虚拟框中。对我来说，类似的设置适用于具有更多RAM的典型硬件。
我现在正在做的解决此问题的方法是安装最新的乘客模块。
gem install passenger并运行passenger-install-apache2-module本身就是乘客。
我认为最新的模块正常运作。
以下是 apache conf dir 下的 puppetmaster.conf 文件条目。
LoadModule passenger_module /usr/local/share/gems/gems/passenger-5.0.26/buildout/apache2/mod_passenger.so
PassengerRoot /usr/local/share/gems/gems/passenger-5.0.26

尝试使用Nginx而不是Apache。 Nginx拥有内置乘客支持，您可以在此处找到Capistrano，Nginx和Passenger的完整部署指南：https://gorails.com/deploy/ubuntu/14.04
