服务器文件夹无法写入缓存,Capifony Symfony2无法写入缓存文件

使用capistrano将开发环境部署到外部开发服务器时,始终会出现以下错误：

RuntimeException: Failed to write cache file "/var/www/xyz.co.uk/app/cache/dev/classes.php".

然后,我必须登录到开发服务器并删除我的app / cache / dev /目录.

这是我的development.rb文件：

server 'x.xx.xx.xxx', :app, :web, :db, :primary => true

ssh_options[:port] = 1234

ssh_options[:forward_agent] = true

set :deploy_to, "/var/www/xyz.co.uk"

set :symfony_env_prod, "dev"

set :branch, "develop"

# Need to clear *_dev controllers

set :clear_controllers, false

和我的deploy.rb文件：

set :stage_dir, 'app/config/deploy' # needed for Symfony2 only

set :stages, %w(production staging development)

require 'capistrano/ext/multistage'

set :application, "xyz.co.uk"

set :user, "root" # The server's user for deploys

set :normalize_asset_timestamps, false

set :repository, "git@github.com:xyz/xyz.co.uk.git"

set :scm, :git

set :keep_releases, 3

set :use_sudo, false

set :web_path, "web"

set :shared_files, ["app/config/parameters.yml"]

set :shared_children, [app_path + "/logs", web_path + "/uploads"]

set :use_composer, true

set :update_vendors, true

set :dump_assetic_assets, true

set :deploy_via, :remote_cache
