如何部署轨2.3.2应用程序与Capistrano从顶部(值)?

Question

免责声明：我是个新手上路轨道和Capistrano(但中间体。净C#开发)试图了解更多信息。

我已经有了最艰难的时候得到一Capistrano发展的进程设置。这是我迄今为止对于我的部署。rb：

set :application, "MyAppName"
set :domain, "domainname"
set :user, "userid" 
set :repository,  "svn+ssh://#{user}@#{domain}/home/#{user}/svn/#{application}/trunk"
set :rails_env, :production
set :chmod755, %w(app config db lib public vendor script tmp public/dispatch.cgi public/dispatch.fcgi public/dispatch.rb)
set :deploy_to, "/home/#{user}/apps/#{application}"
set :use_sudo, false
set :deploy_via, :checkout
set :group_writable, false
default_run_options[:pty] = true
role :app, domain
role :web, domain
role :db,  domain, :primary => true

这是我的Capfile:

load 'deploy' if respond_to?(:namespace) # cap2 differentiator
Dir['vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }
load 'config/deploy'

namespace :deploy do

  task :restart, :roles => :app do
    run "#{current_path}/script/process/reaper --dispatcher=dispatch.fcgi"
  end

  desc "Set the proper permissions for directories and files on HostingRails accounts"
  task :after_deploy do
    run(chmod755.collect do |item|
      "chmod 755 #{current_path}/#{item}"
    end.join(" && "))
  end

end

1. 轨2.3.2没有脚本/程目录，以便重新启动的任务不在所有的工作。我怎么解决这个问题？
2. 有没有一种方法来设定RAILS_ENV变中的环境。rb"生产"当部署应用程序("集：rails_env,：生产"不这样做)?
3. 此外，我错过了什么别从2这些文件吗？

Answer 1

这是我的部署。rb，这还没有真正被更新，在很长一段时间。我运行两个sed命令设置的环境内，我:after_update_code的任务。我肯定有一个更简单的方法来做到这一点，但这是我目前的方法。

require 'erb'

before "deploy:setup", :db
after "deploy:update_code", "db:symlink" 
after "deploy", "deploy:cleanup"

def prompt_with_default(var, default)
  set(var) do
    Capistrano::CLI.ui.ask "Enter #{var} [#{default}] : "
  end

  set var, default if eval("#{var.to_s}.empty?")
end

default_run_options[:pty] = true 

set :rake, "/usr/local/bin/rake"

set :user, "your username"
set :application, "application name"
set :repository,  "svn repository path"
set :host, "domain name"
set :db_host, "DB host name"
set :db_user, "DB user name"
set :db_prefix, "any DB name prefix your host might require"
set :rails_env, "production"

set :deploy_to, "/home/username/rails/#{host}" # your deployment directory

role :app, host
role :web, host
role :db,  host, :primary => true

set :use_sudo, false
set :checkout, "export"

#
# TASKS
#
desc "Tasks to execute after code update"
task :after_update_code, :roles => [:app, :db, :web] do
  # Make sure we're running in production
  run "sed -i -e '/ENV.*RAILS_ENV/s/# //' #{release_path}/config/environment.rb"
  run "sed -i -e '/ENV.*RAILS_ENV/s/production/#{rails_env}/' #{release_path}/config/environment.rb"

  # Add banned IPs
  deny_lines = []
  File.readlines("#{release_path}/config/banned_ips").each {|ip|
    deny_lines << "deny from #{ip}"
  }

  ip_ban_block = <<EOBAN
# Bannination
order allow,deny
#{deny_lines.join}
allow from all
EOBAN

  run "sed -i -e 's/# BANNED IPS/#{ip_ban_block}/' #{release_path}/public/.htaccess"

  run "chmod +x #{release_path}/script/runner" 
  run "chmod +x #{release_path}/script/process/reaper" 
  run "chmod +x #{release_path}/script/process/spawner" 
  run "chmod 755 #{release_path}/public/dispatch.*" 
end

desc "Restarting after deployment"
task :after_deploy, :roles => [:app, :db, :web] do
  run "cd #{current_path} && rake RAILS_ENV=production db:sessions:clear tmp:clear"
  # fix permissions
  run "dos2unix #{release_path}/public/dispatch.*"
  run "dos2unix #{release_path}/public/.htaccess"
  run "chmod -R 755 #{release_path}"
  run "chmod -R 775 #{release_path}/log #{release_path}/tmp #{release_path}/script"
  run "find #{release_path}/ | xargs touch"
  run "touch #{deploy_to}/current/public/dispatch.fcgi"
end

desc "Restarting after rollback"
task :after_rollback, :roles => [:app, :db, :web] do
  run "touch #{deploy_to}/current/public/dispatch.fcgi"
end

namespace :db do
  desc "Create database yaml in shared path" 
  task :default do
  prompt_with_default(:db_password, "")
  db_config = ERB.new <<-EOF
base: &base
  adapter: mysql
  port: 3306
  host: #{db_host}
  username: #{db_user}
  password: #{db_password}

development:
  database: #{db_prefix}#{application}development
  <<: *base

test:
  database: #{db_prefix}#{application}test
  <<: *base

production:
  database: #{db_prefix}#{application}production
  <<: *base
EOF

    run "mkdir -p #{shared_path}/config" 
    put db_config.result, "#{shared_path}/config/database.yml" 
  end

  desc "Make symlink for database yaml" 
  task :symlink do
    run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml" 
  end
end

有一次我设定了我的变量，我有个庆典脚本，运行：

svn export $svn_path . --force
cap deploy

这就要问我为我的密码两次。一旦出口从SVN，并且一旦作为一种提示，以自动生成的数据库。在阳明海运所共享的道路。

Answer 2

更新我的回答，见#3...

我不用FastCGI部署，但一些东西，想到:

1. 该进程的脚本已经搬出轨的核心并进入 一个插件, 你可以抓住从想.

2. 看看我的部署。rb文件，则可能需要通过RAILS_ENV环境，可变成剧本可以通过命令行类似的：

   run #{current_path}/script/process/reaper RAILS_ENV=#{rails_env} --dispatcher=dispatch.fcgi

3. 编辑：实际上，它是有点奇怪有你的任务在Capfile而不是部署。rb-虽然在看 这纹在Capistrano谷歌群, 它不是完全不悦。给你你的团队，我想。

希望这点你在正确的方向。
