我已经成功部署了Ruby on Rails应用程序，并遵循资产pipe道指南来设置资产编译和压缩。 看来我的服务器日志中出现caching问题。
看来我有一个权限被拒绝时试图mkdircaching文件夹？ 这里发生了什么？ 我该如何解决这个问题？
nginx /日志error.log …

我的nginx.conf的一部分…

在nginx.conf设置一个user指令：
user www-data;
然后更新您的应用程序的权限，以便由此用户拥有：
sudo chown -R www-data /var/www/redmeetsblue
注意：另外请注意，如果您正在使用capistrano或其他部署系统，那么您现在也必须更新该配置以使用同一个用户。
