Question

我正在使用Capistrano 2.12.0运行Rails 3.2.x应用程序。我已经从github /版本控制中取出了我的database.yml，并在/home/deploy/myapp/shared/config/database.yml下手动放置了一份副本

我试图让deploy.rb使用before:assets:precompile对此文件进行符号链接，以便在发布目录中对该文件进行符号链接，然后部署就可以继续。这是我得到的错误：

/Users/james/.rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1/gems/capistrano-2.12.0/lib/capistrano/configuration/callbacks.rb:103:in `on': please specify either a task name or a block to invoke (ArgumentError)

这是我的deploy.rb的样子：

deploy.rb

require "bundler/capistrano"
set :whenever_command, "bundle exec whenever"
require "whenever/capistrano"
set :shared_children, shared_children + %w{public/uploads}
server "72.14.181.22", :web, :app, :db, primary: true

set :application, "myapp"
set :user, "deploy"
set :deploy_to, "/home/#{user}/#{application}"
#set :deploy_via, :remote_cache
set :use_sudo, false
set :rails_env, "production"


set :scm, "git"
set :repository, "git@github.com:james/#{application}.git"
set :branch, "master"


default_run_options[:pty] = true
ssh_options[:forward_agent] = true

after "deploy", "deploy:cleanup" # keep only the last 5 releases
after "deploy:update"
before "deploy:assets:precompile", "config_symlink"

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
  desc "reload the database with seed data"
  task :seed do
    run "cd #{current_path}; bundle exec rake db:seed RAILS_ENV=#{rails_env}"
  end
end

task :config_symlink do
  run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
end

基本上我需要做的是在资源预编译之前将/home/deploy/myapp/shared/config/database.yml符号链接到/home/deploy/myapp/current/config/database.yml，这样数据库就可以了访问。

我确定这里有一些语法错误但可以真正使用一些帮助。我希望保持database.yml不受版本控制，直接将其保留在myapp / shared / config中，并在部署时将其符号链接以用于安全目的。

最长的时间我以为我一直这样做，但显然我没有这样做，所以我需要弄清楚这一点。

我非常感谢任何帮助，因为我不想在github /版本控制中使用database.yml。

我认为我有这个工作。它看起来像我原来的deploy.rb，我正在调用after "deploy:update"，但没有传递任何东西到回调，所以它是轰炸我。我已经清理了我的deploy.rb文件并测试了部署到登台服务器，它似乎有效。

deploy.rb已更新

require "bundler/capistrano"
set :whenever_command, "bundle exec whenever"
require "whenever/capistrano"
set :shared_children, shared_children + %w{public/uploads}
server "72.14.181.11", :web, :app, :db, primary: true

set :application, "myapp"
set :user, "deploy"
set :deploy_to, "/home/#{user}/#{application}"
#set :deploy_via, :remote_cache
set :use_sudo, false
set :rails_env, "production"


set :scm, "git"
set :repository, "git@github.com:james/#{application}.git"
set :branch, "master"


default_run_options[:pty] = true
ssh_options[:forward_agent] = true

before "deploy:assets:precompile", "config_symlink"
after "deploy", "deploy:cleanup" # keep only the last 5 releases

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
  desc "reload the database with seed data"
  task :seed do
    run "cd #{current_path}; bundle exec rake db:seed RAILS_ENV=#{rails_env}"
  end
end

task :config_symlink do
  run "ln -nfs #{deploy_to}/shared/config/database.yml #{release_path}/config/database.yml"
end

Capistrano符号链接database.yml任务错误
