Question

我正在尝试使用Ruby 2.2.2，Rails 4，Capistrano 3，Unicorn和Nginx进行部署。当我运行cap production deploy时，我收到一个错误，说明Unicon无法找到或访问“restart”命令的目录，在我的deploy.rb中阻止（我相信）这一行：

execute "/etc/init.d/unicorn_#{fetch(:application)}/unicorn_init.sh/#{command}"

错误：

SSHKit::Runner::ExecuteError: Exception while executing as deploy@0.0.0.0: /etc/init.d/unicorn_app/restart exit status: 126
/etc/init.d/unicorn_app/restart stdout: Nothing written
/etc/init.d/unicorn_app/restart stderr: /usr/bin/env: /etc/init.d/unicorn_app/restart: Permission denied

Deploy.rb

set :application, 'app'
set :repo_url, 'https://github.com/user/app.git'
set :deploy_to, '/opt/www/app'
set :user, 'deploy'
set :linked_dirs, %w{log tmp/pids tmp/cache tmp/sockets}


set :ssh_options, {
forward_agent: true,
port: 7822
}

namespace :deploy do

  %w[start stop restart].each do |command|
    desc 'Manage Unicorn'
    task command do
      on roles(:app), in: :sequence, wait: 1 do
        execute "/etc/init.d/unicorn_#{fetch(:application)}/unicorn_init.sh/#{command}"
      end      
    end
  end

  after :publishing, :restart

end

set :rvm_ruby_version, '2.2.2'
set :default_env, { rvm_bin_path: '/usr/local/rvm/bin' }
SSHKit.config.command_map[:rake] = "#{fetch(:default_env)[:rvm_bin_path]}/rvm ruby-#{fetch(:rvm_ruby_version)} do bundle exec rake"

任何人都可以帮助我吗？我很乐意发布任何遗漏的信息。

编辑：unicorn_init.sh：我知道此文件中引用了“testapp”，但此帖中的其他地方引用了app。请知道我的所有文件都与名称一致，我只是将其更改为帖子。

Unicorn Rails为每个命令寻找单独的文件/目录？
