Heroku migration to Cedar - "ERROR: No application configured, nothing to run"
Heroku migration to Cedar - "ERROR: No application configured, nothing to run"
我正在尝试将 Rails 应用程序上的旧 Heroku Ruby 从 Bamboo 迁移到 Cedar 堆栈。我正在使用 Ruby 1.8.7、Rails 2.3.11 和 Postgres 数据库。
我按照 https://devcenter.heroku.com/articles/cedar-migration 中的说明进行了所有操作，但是通过应用程序启动，我在 heroku 日志中收到消息：
"ERROR: No application configured, nothing to run"
我的个人资料：
web: bundle exec puma -C config/puma.rb
config/puma.rb:
workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['MAX_THREADS'] || 5)
threads threads_count, threads_count
preload_app!
rackup DefaultRackup
port ENV['PORT'] || 3000
environment ENV['RACK_ENV'] || 'development'
on_worker_boot do
# Worker specific setup for Rails 4.1+
# See: https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#on-worker-boot
ActiveRecord::Base.establish_connection
end
宝石文件：
source 'http://rubygems.org'
ruby '1.8.7'
gem 'rake', '~> 0.8.3'
gem 'rails', '2.3.11'
gem 'puma'
gem 'pg', '0.14.1'
gem 'rdoc'
Rakefile:
# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.
require(File.join(File.dirname(__FILE__), 'config', 'boot'))
require 'rake'
require 'rake/testtask'
require 'rdoc/task'
require 'tasks/rails'
本地捆绑包安装工作正常。我在服务器上调用这样的命令：
$ heroku buildpack:set https://github.com/heroku/heroku-buildpack-ruby#legacy-ruby-1.8.7
将提交推送到 Heroku 并执行成功的数据库迁移后，我仍然收到日志：

我忘记删除vendor/rails/actionpack/lib/action_controller.rb中带有rack 1.1.0版本的行。现在应用程序已经启动并且工作起来很有魅力。 Малъ，你是我的救世主！非常感谢。
我已经在 heroku cedar-10 堆栈上 运行 我的 Rails 2.3 应用程序做了一些步骤。不幸的是，它也将很快被删除，这样 heroku 支持就得到了回答。所以：
升级或降级rubygems到1.4.2,需要运行rake冻结:
$ gem update --system 1.4.2
将 rake 添加到 Gemfile。和捆绑设置。
根据 manual，你必须首先将 Rails gem 冻结到 /vendor 文件夹中：
$ rake rails:freeze:gems
修改文件：vendor/rails/actionpack/lib/action_controller.rb支持rack 1.4.0版本：
$ sed "s/gem 'rack', '~> 1.1.0'/gem 'rack', '~> 1.4.0'/" -i vendor/rails/actionpack/lib/action_controller.rb
将rack 1.4.0和puma 2.3.2gem添加到Gemfile，并删除 rails gem ，然后再次捆绑设置：
gem 'rack', '~> 1.4.0'
gem 'puma', '~> 2.3.2'
注意： config/puma.rb 也不再需要了。
通过 rackup:
将 Procfile 更改为 运行 puma
$ cat Procfile
web: bundle exec rackup -s puma -p ${PORT:-3000} -E ${RACK_ENV:-development}
将 config.ru 添加到 运行 Rails 来自 rackup 的应用：
$ cat config.ru
# RAILS_ROOT/config.ru
require "config/environment"
use Rails::Rack::LogTailer
use Rails::Rack::Static
run ActionController::Dispatcher.new
将更改和新增的文件添加到git，并将更改推送到heroku。
由于heroku在生产中默认使用PostgreSQL，创建MySQL db实例，当然如果你打算使用它，根据manual：
$ heroku addons:add cleardb:ignite
-----> Adding cleardb to sharp-mountain-4005... done, v18 (free)
$ heroku config | grep CLEARDB_DATABASE_URL
CLEARDB_DATABASE_URL => mysql://adffdadf2341:adf4234@us-cdbr-east.cleardb.com/heroku_db?reconnect=true
$ heroku config:set DATABASE_URL='mysql://adffdadf2341:adf4234@us-cdbr-east.cleardb.com/heroku_db?reconnect=true'
此外，我必须删除服务器变量
STACK: bamboo-ree-1.8.7
并添加
RAILS_ENV: production
现在，原始应用程序（不是它的测试副本）可以工作了。
此致，
迈克尔
无论如何首先尝试在行尾添加 config.ru (Rails 3.X.X)
我的程序文件
web: bundle exec puma -C config/puma.rb config.ru
我正在尝试将 Rails 应用程序上的旧 Heroku Ruby 从 Bamboo 迁移到 Cedar 堆栈。我正在使用 Ruby 1.8.7、Rails 2.3.11 和 Postgres 数据库。
我按照 https://devcenter.heroku.com/articles/cedar-migration 中的说明进行了所有操作，但是通过应用程序启动，我在 heroku 日志中收到消息：
"ERROR: No application configured, nothing to run"
我的个人资料：
web: bundle exec puma -C config/puma.rb
config/puma.rb:
workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['MAX_THREADS'] || 5)
threads threads_count, threads_count

rackup DefaultRackup

environment ENV['RACK_ENV'] || 'development'

# Worker specific setup for Rails 4.1+
# See: https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#on-worker-boot
ActiveRecord::Base.establish_connection
end
宝石文件：
source 'http://rubygems.org'
ruby '1.8.7'
gem 'rake', '~> 0.8.3'
gem 'rails', '2.3.11'
gem 'puma'
gem 'pg', '0.14.1'

Rakefile:

require(File.join(File.dirname(__FILE__), 'config', 'boot'))
require 'rake'
require 'rake/testtask'

本地捆绑包安装工作正常。我在服务器上调用这样的命令：

我忘记删除vendor/rails/actionpack/lib/action_controller.rb中带有rack 1.1.0版本的行。现在应用程序已经启动并且工作起来很有魅力。 Малъ，你是我的救世主！非常感谢。
我已经在 heroku cedar-10 堆栈上 运行 我的 Rails 2.3 应用程序做了一些步骤。不幸的是，它也将很快被删除，这样 heroku 支持就得到了回答。所以：
升级或降级
rubygems到1.4.2,需要运行rake冻结:$ gem update --system 1.4.2将
rake添加到 Gemfile。和捆绑设置。根据 manual，你必须首先将
Railsgem 冻结到 /vendor 文件夹中：$ rake rails:freeze:gems修改文件：vendor/rails/actionpack/lib/action_controller.rb支持
rack 1.4.0版本：$ sed "s/gem 'rack', '~> 1.1.0'/gem 'rack', '~> 1.4.0'/" -i vendor/rails/actionpack/lib/action_controller.rb将
rack 1.4.0和puma 2.3.2gem添加到Gemfile，并删除railsgem ，然后再次捆绑设置：gem 'rack', '~> 1.4.0' gem 'puma', '~> 2.3.2'注意： config/puma.rb 也不再需要了。
通过
将 Procfile 更改为 运行rackup:puma$ cat Procfile web: bundle exec rackup -s puma -p ${PORT:-3000} -E ${RACK_ENV:-development}将 config.ru 添加到 运行
Rails来自rackup的应用：$ cat config.ru # RAILS_ROOT/config.ru require "config/environment" use Rails::Rack::LogTailer use Rails::Rack::Static run ActionController::Dispatcher.new将更改和新增的文件添加到git，并将更改推送到heroku。
由于heroku在生产中默认使用
PostgreSQL，创建MySQLdb实例，当然如果你打算使用它，根据manual：$ heroku addons:add cleardb:ignite -----> Adding cleardb to sharp-mountain-4005... done, v18 (free) $ heroku config | grep CLEARDB_DATABASE_URL CLEARDB_DATABASE_URL => mysql://adffdadf2341:adf4234@us-cdbr-east.cleardb.com/heroku_db?reconnect=true $ heroku config:set DATABASE_URL='mysql://adffdadf2341:adf4234@us-cdbr-east.cleardb.com/heroku_db?reconnect=true'
此外，我必须删除服务器变量
STACK: bamboo-ree-1.8.7
并添加
RAILS_ENV: production
现在，原始应用程序（不是它的测试副本）可以工作了。
此致，
迈克尔
无论如何首先尝试在行尾添加 config.ru (Rails 3.X.X)
我的程序文件
web: bundle exec puma -C config/puma.rb config.ru
