升级到Ruby版本2.1.2,乘客仍然在1.9.3

Question

每当我使用RVM和Capistrano更新Ruby及其Gemlist时,如何更新Passenger使用的Ruby版本？检查我的应用程序是否使用正确的ruby版本和gemset的最佳方法是什么？

我有一个运行在Linode服务器(Ubuntu)上的Rails应用程序,使用NGinx和Passenger.在它运行之前没有任何问题.

以前我的应用程序使用Ruby 1.9.3-p194运行Ruby on Rails 3.2.16

我使用RVM来管理本地和服务器上的ruby版本.在我安装了Ruby-2.1.2并更新了基本的宝石(bundler,nokogiri等等)后,我为我的应用程序创建了我的新gemset.

在开发(本地)中,我使用Ruby 2.1.2,rails 3.1.19(在我升级到Rails 4之前),以及该项目的特定gemset.

我修改了我deploy.rb的Capistrano,遵循RVM-Capistrano宝石集成

require "rvm/capistrano"
require "bundler/capistrano"

set :user, "myusername"
set :application, "myapp"

set :deploy_to, "/home/#{user}/apps/#{application}"
set :scm, :git
set :repository,  "git@github.com:myusername/#{application}.git"
set :branch, "master"
set :rvm_ruby_string, :local              # use the same ruby as used locally for deployment
set :rvm_autolibs_flag, "read-only"       # more info: rvm help autolibs
set :use_sudo, false
set :deploy_via, :remote_cache
set :keep_releases, 3
default_run_options[:pty] = true
set :ssh_options, { :forward_agent => true }

before 'deploy:setup', 'rvm:install_rvm'  # install/update RVM
before 'deploy:setup', 'rvm:install_ruby' # install Ruby and create gemset

after "deploy:restart", "deploy:cleanup"
after "deploy", "rvm:trust_rvmrc"

namespace :deploy do
  task :start do ; end
  task :stop do ; end
  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end

  # ... some more tasks for assets and symlinks

end

namespace :rvm do
  task :trust_rvmrc do
    run "rvm rvmrc trust #{release_path}"
  end
end

然后我跑了 cap deploy

我刷新了我的网页,Passenger引发了以下错误:

It looks like Bundler could not find a gem. Maybe you didn't install all the gems that this application needs. To install your gems, please run:

bundle install
...
Could not find rake-10.3.2 in any of the sources (Bundler::GemNotFound)
/home/myusername/.rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.5.3/lib/bundler/spec_set.rb:92:in `block in materialize'
...
Ruby interpreter command
/home/myusername/.rvm/gems/ruby-1.9.3-p194/wrappers/ruby

显然,Passenger仍在运行Ruby-1.9.3而不是Ruby-2.1.2.我不确定RVM-Capistrano是否安装/更新了Ruby版本和相应的gemset.我不确定我错过了什么？

编辑: 我检查了nginx.conf作为root用户/opt/nginx/conf/nginx.conf

在我找到的文件的顶部

...

http {
    passenger_root /home/myusername/.rvm/gems/ruby-1.9.3-p194/gems/passenger-4.0.37;
    passenger_ruby /home/myusername/.rvm/gems/ruby-1.9.3-p194/wrappers/ruby;

...

server {
    listen 80;
    server_name XXX.XXX.XX.XX myapp.com www.myapp.com *.myapp.com;
    root /home/myusername/apps/myapp/current/public;
    passenger_enabled on;
    client_max_body_size 4G;
}

这是否意味着我必须使用ruby-2.1.2更改这些行？有没有办法自动化这种变化？

更新2: 我修改了nginx.conf

http {
        passenger_root /home/myusername/.rvm/gems/ruby-2.1.2@rails3.2/gems/passenger-4.0.53;
        passenger_ruby /home/myusername/.rvm/gems/ruby-2.1.2@rails3.2/wrappers/ruby;

并在我的deploy.rb明确告诉使用gemsetruby-2.1.2@rails3.2

set :rvm_ruby_string, "2.1.2@rails3.2"

应用程序运行正常,Ruby解释器仍然是1.9.3.我甚至在管理页面上打印出RUBY_VERSION常量,它显示1.9.3

我不明白......

谢谢你的帮助

如果您使用 Passenger 4 或更高版本，则可以使用 rvm 管理的多个 ruby​​ 版本。

这里有一些指南的链接

https://www.phusionpassenger.com/documentation/Users%20guide%20Apache.html

看起来要在您的服务器中运行乘客安装/升级，您必须rvmsudo -s先运行
