Rails 4 和 ruby 2.5 的 Phusion Passenger 错误

Question

Ubuntu 16.04
Rails 4.2.10
Ruby 2.5.0
SERVER_SOFTWARE = Apache/2.4.18 (Ubuntu) Phusion_Passenger/5.2.2

我使用 rbenv 安装了 ruby，当我这样做时

ruby -v

我明白了

ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-linux]

我安装了 Phusion Passenger 如下：

sudo apt-get install -y dirmngr gnupg
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7
sudo apt-get install -y apt-transport-https ca-certificates
sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger trusty main > /etc/apt/sources.list.d/passenger.list'
sudo apt-get update
sudo apt-get install -y libapache2-mod-passenger
sudo a2enmod passenger
sudo apache2ctl restart

当我这样做时：

sudo /usr/bin/passenger-config validate-install

我得到：

 * Checking whether this Passenger install is in PATH... ✓
 * Checking whether there are no other Passenger installations... ✓
 Everything looks good. :-)

但是，当我尝试启动我的应用程序时，我收到一条错误消息：

Web application could not be started
Web application could not be started by the Phusion Passenger application server.

从 /var/log/apache2/error.log，我得到：

==================================

答案：

答案是卸载stand alone Phusion Passenger，安装成gem，如下：

sudo apt-get remove -y passenger libapache2-mod-passenger

然后安装 gem

gem install passenger --no-rdoc --no-ri
passenger-install-apache2-module

按照安装说明进行操作
