php - Cakephp could not create tmp folder -

i'm using vagrant setup centos 6.6 x86_64 virtual os. have installed apache , cakephp it.

i have let apache run vagrant user , in vagrant group. , vagrant's vagrantfile has line config.vm.synced_folder "./gym", "/var/www", mount_options: ["dmode=777", "fmode=777"].

after run index.php, cakephp report error:

php warning: /var/www/gym_new/app/tmp/cache/persistent/ not writable in /var/www/cake_2_6/cake/cache/engine/fileengine.php on line 385

php warning: _cake_core_ cache unable write 'file_map' file cache in /var/www/cake_2_6/cake/cache/cache.php on line 328

so open fileengine.php there code trigger error:

/**  * determine cache directory writable  *  * @return bool  */     protected function _active() {         $dir = new splfileinfo($this->settings['path']);         if (configure::read('debug')) {             $path = $dir->getpathname();             if (!is_dir($path)) {                 mkdir($path, 0775, true);             }         }         if ($this->_init && !($dir->isdir() && $dir->iswritable())) {             $this->_init = false;             trigger_error(__d('cake_dev', '%s not writable', $this->settings['path']), e_user_warning);             return false;         }         return true;     } 

i think permission has no problem create brand new php under webroot:

$path = "/var/www/gym_new/app/tmp/cache/"; if(mkdir($path, 0775, true) && is_dir($path) && is_writable($path)) {     echo "true"; } else {     echo "false";     $error = error_get_last();     echo $error['message']; } 

my code runs perfect , folders (tmp , cache) created successful. same code in cakephp cannot go through. there have missed? the cakephp file outside of webroot, dose cause problem ?

the problem if (configure::read('debug')).

i found haven't set debug non-zero value, cakephp won't create folders don't exist.
