Question

尝试通过gem Capistrano将我的应用部署到托管时遇到问题。通过SSH密钥授权一切正常。我有下一个错误：

(Backtrace restricted to imported tasks)
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as hosting_yurta24@calcium.locum.ru: scp: /tmp/yurta24/git-ssh.sh: Permission denied
scp: /tmp/yurta24/git-ssh.sh: Permission denied

我的deploy.rb文件是：

lock '3.4.0'

require 'net/ssh/proxy/http'

sshproxy = Net::SSH::Proxy::HTTP.new('x.x.x.x', 8080)
set :ssh_options, { :proxy => sshproxy }

    application = 'yurta24'
    login = 'yurta24'
    $user = 'hosting_' + login
    $server = 'calcium.locum.ru'
    rvm_ruby_string = '2.1.5p273'
    deploy_to = "/home/#{ $user }/projects/#{ application }"
    unicorn_conf = "/etc/unicorn/#{ application }.#{ login }.rb"
    unicorn_pid = "/var/run/unicorn/#{ $user }/#{ application }.#{ login }.pid"
    unicorn_start_cmd = "(cd #{ deploy_to }/current; rvm use #{ rvm_ruby_string } do bundle exec unicorn_rails -Dc #{ unicorn_conf })"

    set :application, application 
    set :repo_url, "https://github.com/verrom/yurta24.git"
    set :deploy_to, deploy_to
    set :pty, true
    set :default_env, { path: "/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/usr/local/rvm/bin" }

  namespace :deploy do
  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
    end
  end

  after :publishing, :restart

  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
    end
  end
end

我的production.rb文件是：

connect_to = "#{$user}@#{$server}"
role :app, [connect_to]
role :web, [connect_to]
role :db,  [connect_to]
set :enable_ssl, true

Answer 1

由于这是一个权限问题，它可能是许多事情之一;但是，请确保您的用户“hosting_yurta24”拥有/ tmp目录

$ sudo chown hosting_yurta24 /tmp

这可能是因为当您创建此用户时，您没有为其分配管理权限。

关于您的第二个问题，capistrano报告您的VPS上没有database.yml文件。我猜你也没有secrets.yml。以下是创建它们的方法：

首先确保你有这两个目录。如果您还没有它们，请创建它们：

/home/hosting_yurta24/projects/yurta24/shared/config
/home/hosting_yurta24/projects/yurta24/log

第一个目录将保存您的项目和数据库配置。第二个目录对于应用程序保存日志至关重要。他们都必须在那里！

现在！ cd进入/home/hosting_yurta24/projects/yurta24/shared/config并创建两个文件

database.yml
secrets.yml

在database.yml中粘贴以下内容：

production:
  adapter: postgresql                # if your using postgresql
  encoding: unicode
  pool: 5
  timeout: 5000
  database: yurta24_production       # database name
  username: postgres                 # database username
  password: password                 # database password
  host: localhost

返回本地计算机，进入rails项目目录，然后从终端输入：

rake secret

终端应该转储一长串字符串和数字。这是你的申请秘密。复制它，然后复制到你的VPS secrets.yml：

production:
  secret_key_base: apsifq193uq8djf1jqe8er18jee9jd8eqeh8fqe8fqehh8qehfq    # paste your secret here

希望这有帮助。

Answer 2

无法向该/tmp文件夹添加适当的用户权限。

但是，更改临时路径是可行的。将此添加到您的deploy.rb：

set :tmp_dir, "/home/deploy"

SSHKit :: Runner :: ExecuteError权限被拒绝
