Question

我尝试使用带有nginx，passenger和postresql的ubuntu 16.0.4部署到服务器。现在，当我第一次部署时，它一直工作，直到capistrano运行rake db：migrate。

RBENV_VERSION="2.3.3" RAILS_ENV="production" ; $HOME/.rbenv/bin/rbenv exec bundle exec rake db:migrate )
 DEBUG [c5c99ee8]   == 20160922103610 AddSignToUsers: migrating ===================================
 DEBUG [c5c99ee8]   -- add_column(:users, :sign, :string)
 DEBUG [c5c99ee8]   rake aborted!
 DEBUG [c5c99ee8]   StandardError: An error has occurred, this and all later migrations canceled:

PG::UndefinedTable: ERROR:  relation "users" does not exist

我明白这是因为我没有创造这些表格。我是capistrano和奇迹的新人。我需要为此编写单独的任务吗？

继承我的deploy.rb

# Change these
server '83.241.146.21', user: 'deploy', roles: %w{app db web}
set :repo_url,        'git@bitbucket.org:gjores/prognoser.git'
set :application,     'prognoser'


# Don't change these unless you know what you're doing
set :pty,             true
set :use_sudo,        false
set :stage,           :production
set :deploy_via,      :remote_cache
set :deploy_to,       "/home/deploy/prognoser"
set :ssh_options, {:forward_agent => true}
on :start do    
  `ssh-add`
end


## Defaults:
# set :scm,           :git
# set :branch,        :master
# set :format,        :pretty
set :log_level,     :debug
set :keep_releases, 5

## Linked Files & Directories (Default None):
 set :linked_files, %w{config/database.yml}
 set :linked_dirs,  %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
namespace :deploy do
#   task :db_schema_load do 
#     on roles(:db) do
#       within release_path do
#         with rails_env: (fetch(:rails_env) || fetch(:stage)) do
#           execute :rake, 'db:schema:load'
#         end
#       end
#     end
#   end

# end
# namespace :deploy do
#   desc "Make sure local git is in sync with remote."
#   task :check_revision do
#     on roles(:app) do
#       unless `git rev-parse HEAD` == `git rev-parse origin/master`
#         puts "WARNING: HEAD is not the same as origin/master"
#         puts "Run `git push` to sync changes."
#         exit
#       end
#     end
#   end

  desc 'Initial Deploy'
  task :initial do
    on roles(:app) do
      before 'deploy:restart'
      invoke 'deploy'
    end
  end

#   desc 'Restart application'
#   task :restart do
#     on roles(:app), in: :sequence, wait: 5 do
#       invoke 'puma:restart'
#     end
#   end

#   before :starting,     :check_revision
#   after  :finishing,    :compile_assets
#   after  :finishing,    :cleanup
#   after  :finishing,    :restart
 end

# ps aux | grep puma    # Get puma pid
# kill -s SIGUSR2 pid   # Restart puma
# kill -s SIGTERM pid   # Stop puma

尝试使用命令加载模式：

RAILS_ENV=production rake db:schema:load

首次将rails app部署到服务器capistrano
