ruby-on-rails - Capistrano 部署瘦服务器

Question

一直在使用 Capistrano 在我的服务器和我的开发机器之间进行自动部署。我几乎已经配置好了，只是 Capistrano 似乎无法使用 bundle exec 命令启动我的服务器。我总是收到以下错误：

编辑：配置文件现在位于 /var/www/apps/current/thin.yml

...
  * 执行“sudo -p 'sudo 密码：' bundle exec thin start -C /var/www/thin.config.yml”
    服务器：[“85.255.206.157”]
    [85.255.206.157] 执行命令
 ** [out :: 85.255.206.157] 找不到 Gemfile
    命令在 216 毫秒内完成
失败：“sh -c 'sudo -p '\\''sudo 密码：'\\'' bundle exec thin start -C /var/www/thin.config.yml'” on 85.255.206.157

只复制了相关的最后一部分。文件等的整个复制工作正常。它只是启动似乎失败的集群。这是我处理所有 Capistrano 内容的 deploy.rb 文件：

编辑：该文件已修改为以下内容：

require "bundler/capistrano"

# define the application and Version Control settings
set :application, "ESCO Matching Demo"
set :repository,  "svn://192.168.33.70/RubyOnRails/ESCO"
set :deploy_via, :copy

# Set the login credentials for Capistrano
set :user, "kurt"

# Tell Capistrano where to deploy
set :deploy_to, "/var/www/apps"

# Tell Capistrano the servers it can play with
server "85.255.206.157", :app, :web, :db, :primary => true

# Generate an additional task to fire up the thin clusters
namespace :deploy do
  desc "Start the Thin processes"
  task :start do
    sudo "bundle exec thin start -C thin.yml"
  end

  desc "Stop the Thin processes"
  task :stop do
    sudo "bundle exec thin stop -C thin.yml"
  end

  desc "Restart the Thin processes"
  task :restart do
    sudo "bundle exec thin restart -C thin.yml"
  end

  desc "Create a symlink from the public/cvs folder to the shared/system/cvs folder"
  task :update_cv_assets, :except => {:no_release => true} do
    run "ln -s #{shared_path}/cvs #{latest_release}/public/cvs"
  end
end

# Define all the tasks that need to be running manually after Capistrano is finished.
after "deploy:finalize_update", "deploy:update_cv_assets"
after "deploy", "deploy:migrate"

编辑：这是我的 thin.yml 文件

编辑： 现在正在发生以下问题：

在最后一步从我的系统运行 cap deploy 命令时，我收到 Cannot find GemFile 错误：服务器的启动
不执行迁移
我似乎也无法手动启动集群了。只有一个瘦实例正在启动。

更新：这是我部署到的服务器的 gem env 设置。该信息是通过使用 cap shell 然后运行以下命令获得的：

终于解决了这个问题......首先为了让捆绑应用程序与环境服务器很好地配合，下面的脚本做了它应该做的事情：

require "bundler/capistrano"
default_run_options[:pty] = true

# define the application and Version Control settings
set :application, "ESCO Matching Demo"
set :repository,  "svn://192.168.33.70/RubyOnRails/ESCO"
set :deploy_via, :copy
set :user, "kurt"
set :deploy_to, "/var/www/apps"

# Tell Capistrano the servers it can play with

server "85.255.206.157", :app, :web, :db, :primary => true

# Generate an additional task to fire up the thin clusters
namespace :deploy do
  desc "Start the Thin processes"
  task :start do
    run  <<-CMD
      cd /var/www/apps/current; bundle exec thin start -C config/thin.yml
    CMD
  end

  desc "Stop the Thin processes"
  task :stop do
    run <<-CMD
      cd /var/www/apps/current; bundle exec thin stop -C config/thin.yml
    CMD
  end

  desc "Restart the Thin processes"
  task :restart do
    run <<-CMD
      cd /var/www/apps/current; bundle exec thin restart -C config/thin.yml
    CMD
  end

  desc "Create a symlink from the public/cvs folder to the shared/system/cvs folder"
  task :update_cv_assets, :except => {:no_release => true} do
    run <<-CMD
      ln -s /var/www/shared/cvs /var/www/apps/current/public
    CMD
  end
end

# Define all the tasks that need to be running manually after Capistrano is finished.
after "deploy:finalize_update", "deploy:update_cv_assets"
after "deploy", "deploy:migrate"

该脚本可以很好地导航到所需的部署结构并执行控制精简过程所需的命令。问题是 cd 命令在以 sudo 运行时没有完成。这背后的原因是 cv 仅存在于 shell 中，而不是 sudo 的已知命令。

第二个问题是精简配置。由于thin.yml 上有一个小类型，瘦服务器无法启动。下面的脚本会启动一个由 4 个瘦服务器组成的集群，该集群在端口 4000 -> 4003 上运行。

max_conns: 1024
require: []

environment: production
max_persistent_conns: 512
servers: 4
daemonize: true
chdir: /var/www/apps/current

伙计，找出 GEM_HOME 或 GEM_PATH 指向的位置。一定是它。
