Symfony 部署权限错误

我正在我的服务器上进行第一次部署，但是我在permisions方面遇到了问题。

我正在使用 jenkins 部署我的构建步骤如下所示：

 echo '
  parameters:
     database_driver: pdo_mysql
     database_host: %database.host%
     database_port: null
     database_name: symfonyapp
     database_user: %database.user%
     database_password: %database.password%
     mailer_transport: smtp
     mailer_host: 127.0.0.1
     mailer_user: null
     mailer_password: null
     locale: cs
     secret: 08b6b8f6548a96bd1ff1533ec02e39ae
  '> app/config/parameters.yml
export SYMFONY__DATABASE__USER=user
export SYMFONY__DATABASE__HOST=localhost
export SYMFONY__DATABASE__PASSWORD=secret
composer.phar install --optimize-autoloader
php app/console cache:clear --env=prod --no-debug
php app/console assetic:dump --env=prod --no-debug
touch app/logs/prod.log
chmod -R 777 app/cache
chmod -R 777 app/logs

但是我收到此错误并且不知道为什么，因为我设置了所有内容，文件夹日志和缓存也是可写的
