关于这意味着什么,文档似乎有点稀疏。

我正在尝试设置由多级 capistrano 脚本部署的应用程序。

编辑:我正在尝试将相同的应用程序两次部署到同一台服务器。唯一真正的区别(除了 git 分支)是我想将每个副本部署到不同的文件夹。第一个实例是一个登台,我可以在与第二个实例完全相同的环境中测试应用程序,第二个实例是一个生产实例。capistrano 能做到这一点吗?

我运行暂存部署没有任何问题。但是,当我运行任何指定生产阶段的任务时(例如部署:设置,在这种情况下),我收​​到以下错误:

`deploy:setup' is only run for servers matching {:except=>{:no_release=>true}}, but no servers matched

这是我的 Deploy.rb

require "rvm/capistrano"
require "bundler/capistrano"
require "capistrano/ext/multistage"

#server "direct.measuremyho.me", :web, :app, :db, primary: true

set :stages, %w{staging production} # Set staging and production environment
set :default_stage, "staging" # Use staging environment as the default one to prevent accidentally deploying to production 

set :application, "mmh"
set :user, "mmh"
set :deploy_via, :remote_cache
#set :deploy_to, "/var/www/#{application}"
set :use_sudo, false
set :keep_releases, 3

set :scm, "git"
set :repository, "git@localhost:#{application}.git"
set :local_repository, "git@direct.measuremyho.me:#{application}.git"
#set :branch, "master"

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

after "deploy:update_code", "deploy:migrate"
after "deploy", "deploy:cleanup"

namespace :deploy do
  %w[start stop].each do |command|
    desc "#{command} nginx server"
    task command, roles: :app, except: {no_release: true} do
      sudo "#{try_sudo} service nginx #{command}"
    end
  end

  desc "restart passenger server"
  task :restart, roles: :app, except: { no_release: true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end

  task :setup_config, roles: :app do
    # link the nginx config file in the app
    # sudo "ln -nfs #{current_path}/config/nginx.conf "\
    #      "/opt/nginx/conf/nginx.conf"
    # make the shared rails config directory
    run "mkdir -p #{shared_path}/config"
    # ftp the database.yml file to that directory
    put File.read("config/database.yml"), "#{shared_path}/config/database.yml"
    # make the shared uploads directory
    run "mkdir -p #{shared_path}/uploads"
    # tell the user to edit database.yml
    puts "==> IMPORTANT!!! Now edit database.yml in "\
         "#{shared_path}/config <==="
  end

  after "deploy:setup", "deploy:setup_config"

  task :symlink_config, roles: :app do

    run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
    run "rm -rf #{release_path}/public/uploads"
    run "ln -nfs #{shared_path}/uploads #{release_path}/public/"
  end

  after "deploy:finalize_update", "deploy:symlink_config"

end

我的登台.rb

set :application_directory, "staging"
set :rails_env, "staging"
set :main_server, 'direct.measuremyho.me'
set :branch do
  default_tag = `git tag`.split("\n").last
  tag = Capistrano::CLI.ui.ask "Tag to deploy (make sure to push the tag first): [#{default_tag}] "
  tag = default_tag if tag.empty?
  branch = "release/#{tag}"
  branch
end

# Do not modify
# Set up the server
server "#{main_server}", :web, :app, :db, :primary => true
set :deploy_to, "/var/www/mmh/#{application_directory}" 

我的生产.rb

set :application_directory, "production"
set :rails_env, "production"
set :main_server, 'direct.measuremyho.me'
set :branch, "master"

# Do not modify
# Set up the server
server "#{main_server}", :web, :app, :db, :primary => true
set :deploy_to, "/var/www/mmh/#{application_directory}" 

我的问题是,为什么要设置这个?此外,我可以做些什么来避免设置这个变量,以便我可以使用部署命令。

如果我错过了任何相关信息,请告诉我。

我现在通过替换以下行解决了这个问题:

server "#{main_server}", :web, :app, :db, :primary => true

和:

server "#{main_server}", :web, :app, :db, :primary => true, :no_release => false

在我的 production.rb 文件中。

但是,这是一个 hacky 解决方案,我想了解我应该如何正确地将 rails 应用程序两次部署到同一台服务器,以用于暂存和生产目的。或者,为什么我不应该这样做,以及替代方案是什么。所以,我没有回答这个问题。

我试图通过提供一个包含其步骤的教程来扩展这个有用的答案,以及设置一个自托管的 git 存储库而不是 github 和部署脚本,以便在同一服务器上暂存和生产应用程序版本。所以这个问题回答了这个过程的一个关键部分。我试图了解在这种情况下的最佳实践是什么。

欢迎评论;我会将它们添加到此答案中。
