我一直在尝试在配备 Apache2、mysql、neo4j 的 vagrant box 中运行 Cakephp 应用程序，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，出现了这些错误。
这是调试日志:

我打开了所有权限(通过在 ./tmp 文件夹中执行“sudo chmod -R 777 .”)对/tmp 中的所有文件夹，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 session 文件。
Edits & New developments :所以，我意识到当代码与主机和 vagrant guest 操作系统共享时，代码中的 tmp 文件夹实际上已挂载，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、 session 等写入虚拟操作系统文件系统内的外部文件夹？
我尝试使用以下建议:http://singletonio.blogspot.in/2009/01/changing-tmp-directory-of-cakephp-so-it.html
但是，新的日志、 session 没有写在 ~/tmp 上(这是我设置缓存、 session 、日志文件夹的地方)？
你能帮帮我吗？
最佳答案
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
