ruby-on-rails – capistrano git部署：无法创建工作树目录：权限被拒绝

我正在使用git和capistrano与乘客一起部署.我一直在试图做这项工作几个小时,并没有取得多大进展. cap deploy：安装程序正常,但是cap部署失败并出现权限问题.我尝试在我的切片上更改权限/所有权,但它仍然失败.

require 'bundler/capistrano'
set :user,'some_user'
set :domain,'example.com'
set :applicationdir,"/home/some_user/public_html/example"
set :port,30000

set :scm,'git'
set :repository,"ssh://git@123.45.678.910:50000/home/git/example"
set :branch,'master'
set :scm_verbose,true

# roles (servers)
role :web,domain
role :app,domain
role :db,domain,:primary => true

# deploy config
set :deploy_to,applicationdir
set :deploy_via,:remote_cache

# additional settings
default_run_options[:pty] = true  
ssh_options[:forward_agent] = true

# Passenger
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
end

导致以下错误：

解决方法

不确定这会有多大帮助,但在部署：setup之后我总是遇到权限问题

运行deploy：setup时,它会为您创建初始目录.但是它创建的那些文件夹通常由root拥有(在我的大多数情况下都是如此).

webapp/
  shared     root:root
  releases   root:root

为了解决这个问题,我将把这些新文件夹的所有权更改为将要使用的用户.

webapp/
  shared     myuser:myuser
  releases   myuser:myuser

完成后,我将继续我的部署：更新
