rails 4 mina部署失败

我正在部署使用mina部署的rails 4应用程序.我的部署脚本是

require 'mina/bundler'
require 'mina/rails'
require 'mina/git'
require 'mina/rvm'    # for rvm support. (http://rvm.io)

set :domain,'someplace.com'
set :deploy_to,'/home/deploy/projects/website'
set :repository,'[e-mail]:someone/repo.git'
set :branch,'master'

set :identity_file,"#{ENV['HOME']}/.ssh/id_rsa"
set :user,'deploy'    # Username in the server to SSH to.

set :shared_paths,['config/database.yml','config/credentials.yml','log','tmp']

task :environment do
  invoke :'rvm:use[ruby-2.1.0@default]'
end

task :setup => :environment do
  queue! %[mkdir -p "#{deploy_to}/shared/log"]
  queue! %[chmod g+rx,u+rwx "#{deploy_to}/shared/log"]

  queue! %[mkdir -p "#{deploy_to}/shared/config"]
  queue! %[chmod g+rx,u+rwx "#{deploy_to}/shared/config"]

  queue! %[touch "#{deploy_to}/shared/config/database.yml"]
  queue  %[echo "-----> Be sure to edit 'shared/config/database.yml'."]

  queue! %[touch "#{deploy_to}/shared/config/credentials.yml"]
  queue  %[echo "-----> Be sure to edit 'shared/config/credentials.yml'."]
end

desc "Deploys the current version to the server."
task :deploy => :environment do
  deploy do
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:assets_precompile'

    to :launch do
      queue "touch #{deploy_to}/tmp/restart.txt"
    end
  end
end

当我部署为’mina deploy’时,我得到错误

解决方法

如果没有ssh进入服务器,请确保创建了shared / tmp目录

$mkdir /home/deploy/projects/website/shared/tmp

确保你也拥有正确的权限.drwxr-XR-X
