#ruby-on-rails #puma #rbenv #capistrano3

Вопрос:

в Интернете найдено много проблем с этой проблемой, но я не нашел ни одной, которая могла бы решить мою проблему, и мне трудно понять все.

Это моя единственная проблема.

Я начал переписывать приложение ruby on rails, используя rbenv. Я хочу попробовать развернуть это приложение с помощью Capistrano Puma и Nginx (нужен ли мне также Passenger или я могу использовать только Puma?)

Я написал свой проект на локальном компьютере. и теперь я пытаюсь развернуть ее на сервере. но с самого начала у меня возникла эта проблема с конфигурацией Capistrano.

Здесь что не так?

 $ cap --tasks --trace
** Invoke load:defaults (first_time)
** Execute load:defaults
cap aborted!
Don't know how to build task 'start' (See the list of available tasks with `cap --tasks`)

/config/deploy/production.rb

 # server-based syntax
# ======================
# Defines a single server with a list of roles and multiple properties.
# You can define all roles on a single server, or split them:
set :stage, :production # this defines production stage for deployment

set :branch, 'master'
server "seances.ecranvillage.ovh", user: "deploy", roles: %w{app db web}, my_property: :my_value
# server "example.com", user: "deploy", roles: %w{app web}, other_property: :other_value
# server "db.example.com", user: "deploy", roles: %w{db}




# role-based syntax
# ==================

# Defines a role with one or multiple servers. The primary server in each
# group is considered to be the first unless any hosts have the primary
# property set. Specify the username and a domain or IP for the server.
# Don't use `:all`, it's a meta role.

# role :app, %w{deploy@example.com}, my_property: :my_value
# role :web, %w{user1@primary.com user2@additional.com}, other_property: :other_value
# role :db,  %w{deploy@example.com}



# Configuration
# =============
# You can set any configuration variable like in config/deploy.rb
# These variables are then only loaded and set in this stage.
# For available Capistrano configuration variables see the documentation page.
# http://capistranorb.com/documentation/getting-started/configuration/
# Feel free to add new variables to customise your setup.



# Custom SSH Options
# ==================
# You may pass any option but keep in mind that net/ssh understands a
# limited set of options, consult the Net::SSH documentation.
# http://net-ssh.github.io/net-ssh/classes/Net/SSH.html#method-c-start
#
# Global options
# --------------
set :ssh_options, {
    keys: %w(/home/deploy/.ssh/id_rsa),
#    forward_agent: false,
#    auth_methods: %w(password)
}
#
# The server-based syntax can be used to override options:
# ------------------------------------
# server "example.com",
#   user: "user_name",
#   roles: %w{web app},
#   ssh_options: {
#     user: "user_name", # overrides user setting above
#     keys: %w(/home/user_name/.ssh/id_rsa),
#     forward_agent: false,
#     auth_methods: %w(publickey password)
#     # password: "please use keys"
#   }

Я добавил файлы, такие как /config/secrets.yml и т. Д…

Возможно, я не использую хорошую практику для использования Capistrano… почему я не могу это сделать?

1. bundle exec cap --tasks --trace работает ли?

2. bundle exec решил проблему для меня.

3. Вы поняли это? Я только что обновил свое приложение Rails до версии 6.1, и теперь у меня точно такая же проблема

Ответ №1:

в основном это связано с проблемами с обновленной версией ruby, rails и ubuntu. У меня такая же проблема.

Добавлена в Capfile эта строка перед последней строкой, и это решило мою проблему (только если ваша версия puma <5 ).

 install_plugin Capistrano::Puma::Daemon

Для справки следуйте приведенному ниже руководству. Было бы полезно для кого-то. Потому что я потратил много времени, чтобы найти решение для этого.
https://matthewhoelter.com/2020/11/10/deploying-ruby-on-rails-for-ubuntu-2004.html

Ответ №2:

Вам нужно добавить это в свой Capfile в соответствии с документами

install_plugin Capistrano::Puma::Daemon # If you using puma daemonized (not supported in Puma 5 )

Приветствия

Ответ №3:

bundle exec cap --tasks --trace работает

 cap puma:make_dirs                  # Create Directories for Puma Pids and Socket
cap puma:nginx_config               # Setup nginx configuration
cap puma:phased-restart             # phased-restart puma
cap puma:restart                    # restart puma
cap puma:start                      # Start puma
cap puma:status                     # status puma
cap puma:stop                       # stop puma
cap puma:workers:count              # Add a worker
cap puma:workers:less               # Worker--
cap puma:workers:more               # Worker

но cap <environment> deploy сбой

Исправлено: добавить bundle exec в cap <environment> deploy команду

Что изменилось?: Я использовал oh-my-zsh bundler плагин with, который автоматически загружается bundle exec в мою оболочку, но недавно я удалил его, чтобы ускорить запуск терминала

1. Спасибо за ответ. Извините, я попытался удалить rbenv для установки rvm, и теперь у меня другие проблемы… Я возвращаюсь к первому проекту, который был развернут пять лет назад и выпущен, но без capistrano и puma, как и раньше, с passenger. Но плохой идеей было попробовать изменить мой менеджер версий…
