Capistrano：my.server.ipadress上不存在链接文件database.yml
在我尝试通过capistrano将我的应用程序部署到我的服务器后，我收到以下错误消息：
DEBUG [605f198a] Finished in 0.084 seconds with exit status 1 (failed). ERROR linked file /home/deploy/myrailsapp/shared/config/database.yml does not exist on xx.xxx.xx.xxx (Backtrace restricted to imported tasks) cap aborted! SSHKit::Runner::ExecuteError: Exception while executing as deploy@xx.xxx.xx.xxx: exit SystemExit: exit Tasks: TOP => deploy:check:linked_files (See full trace by running task with --trace) The deploy has failed with an error: Exception while executing as deploy@xx.xxx.xx.xxx: exit 我的deploy.rb是：
set :deploy_to, '/home/deploy/myrailsapp' 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 desc 'Restart application' task :restart do on roles(:app), in: :sequence, wait: 5 do execute :touch, release_path.join('tmp/restart.txt') end end after :publishing, 'deploy:restart' after :finishing, 'deploy:cleanup' end namespace :deploy do after :restart, :clear_cache do on roles(:web), in: :groups, limit: 3, wait: 10 do # Here we can do anything such as: # within release_path do # execute :rake, 'cache:clear' # end end end end
我尝试了这个tut https://www.gorails.com/deploy/ubuntu/14.04 ，这是我第一次尝试使用capistrano。
只需手动创建/home/deploy/myrailsapp/shared/config/database.yml文件并进行调整即可。
Capistrano不会创建（或管理）开箱即用的配置文件。 因此，您应该手动执行或自动使用自己的Capistrano脚本， Puppet ， Chef ， Ansible工具。
由于我更喜欢将我的文件放在部署服务器上，我使用此任务将配置文件中的配置文件部署到应用服务器上的链接文件目录。
这使用rsync，因为我使用capistrano-rsync进行部署。
namespace :deploy do task :copy_config do on release_roles :app do |role| fetch(:linked_files).each do |linked_file| user = role.user + "@" if role.user hostname = role.hostname linked_files(shared_path).each do |file| run_locally do execute :rsync, "config/#{file.to_s.gsub(/.*\/(.*)$/,"\\1")}", "#{user}#{hostname}:#{file.to_s.gsub(/(.*)\/[^\/]*$/, "\\1")}/" end end end end end end before "deploy:check:linked_files", "deploy:copy_config"
使用capistrano-rails 1.2.3，如下所示，将其添加到deploy.rb
## Linked Files & Directories (Default None): set :linked_files, %w{config/database.yml config/secrets.yml config/nginx.conf} set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
