Vagrant 中的 Cakephp：无法创建会话、缓存、缓存模型

Question

我一直在尝试在 vagrant box 中运行一个 Cakephp 应用程序，它配备了 Apache2、mysql、neo4j，以及应用程序运行所需的一切。该站点正在打开，当我尝试在本地登录时，它给了我一堆错误。

这是调试日志：

我打开了对 /tmp 中所有文件夹的所有权限（通过在 ./tmp 文件夹中执行“sudo chmod -R 777.”），但错误仍然存​​在。不确定为什么应用程序无法在 tmp 目录中创建新的会话文件。

编辑和新开发：所以，我意识到由于代码与主机和 vagrant guest os 共享，代码中的 tmp 文件夹实际上已安装，这可能是原因对于未授予权限的错误。

现在问题已简化为如何在 /vagrant/ 文件夹之外创建一个“tmp”文件夹，并将所有日志、缓存、会话等写入虚拟操作系统文件系统内的该外部文件夹中？

我已尝试使用以下建议：http://singletonio.blogspot.in/2009/01/changing-tmp-directory-of-cakephp-so-it.html

但是，新的日志、会话并没有写入 ~/tmp（这是我设置缓存、会话、日志文件夹的地方）？

你能帮帮我吗？

我所做的是将开发服务器中的 Apache 用户从“www-data”更改为“vagrant”。

编辑 /etc/apache2/envvars:

export APACHE_RUN_USER=vagrant
export APACHE_RUN_GROUP=vagrant
