Php Symfony 2.8-会话和细枝问题

我在没有ssh的主机上部署了symfony 2.8中的小应用程序。复制了所有没有缓存和日志的文件，克隆了数据库。 当我转到地址：address.com/web/app.php时，应用程序显示错误：

我将chmod777添加到缓存和日志目录中。

有什么想法吗？

这是一个典型的权限问题。您应该清除缓存，然后递归添加适当的权限，如下所示：

chmod -R 775 /cache

清除缓存并重试0775应该足够了我同意，只是从OP复制了权限，因为它不是问题的主要主题。在任何情况下，都应该正确设置对其project的所有文件的权限。OP已经声明他对缓存和日志目录进行了chmod。是的，我相信问题在于他没有递归地进行此操作，而只是在父目录中。我创建了新项目并进行了部署。工作所以我试着做一个新项目，并从旧项目中复制所有内容
