CakePHP 2.x SplFileInfo warning due to cakeshell

Question

I wrote a cakeshell script that I plan to use with cronjob. running it manually (during testing), sometimes my site will trigger a SplFileInfo warning, for example:

Warning: SplFileInfo::openFile(/var/www/flat/app/tmp/cache/persistent/myapp_cake_core_file_map): 
failed to open stream: Permission denied in /var/www/flat/lib/Cake/Cache/Engine/FileEngine.php on line 313

Warning (512): SplFileInfo::openFile(/var/www/flat/app/tmp/cache/models/myapp_cake_model_default_flat_list):

Warning (512): _cake_model_ cache was unable to write 'default_flat_list' to File cache [CORE/Cake/Cache/Cache.php, line 309]

Warning (512): _cake_model_ cache was unable to write 'default_flat_list' to File cache [CORE/Cake/Cache/Cache.php, line 309]

What happened? and how to fix it?

If I check the tmp directory for cache and persistent, some of the files are under root privileges. This is the reason?

[root@Apps103 persistent]# ls
total 40K
-rw-rw-r-- 1 apache   43 Apr 22 17:49 myapp_cake_core_cake_
-rw-rw-r-- 1 root     43 Apr 23 10:01 myapp_cake_core_cake_console_
-rw-rw-r-- 1 root     43 Apr 23 10:01 myapp_cake_core_cake_dev_
-rw-rw-r-- 1 apache   43 Apr 23 10:26 myapp_cake_core_cake_dev_en-us
-rw-rw-r-- 1 apache   43 Apr 23 10:26 myapp_cake_core_cake_en-us
-rw-rw-r-- 1 apache   43 Apr 23 10:26 myapp_cake_core_default_en-us
-rw-rw-r-- 1 root   4.3K Apr 23 10:01 myapp_cake_core_file_map
-rw-rw-r-- 1 root   4.3K Apr 23 10:01 myapp_cake_core_method_cache

I tried the solution at this link SplFileInfo :: openFile (/ app / tmp / cache / persistent / cake_core_cake_console _): could not open the stream: Permission denied in / lib /.../ FileEngine.php line 293

I put this in bootstrap

Cache::config('default', array(
    'engine' => 'File',
    'mask' => 0666,
));

// short  
Cache::config('short', array(
    'engine' => 'File',
    'duration' => '+1 hours',
    'path' => CACHE,
    'prefix' => 'cake_short_'
));

// long
Cache::config('long', array(
    'engine' => 'File',
    'duration' => '+1 week',
    'probability' => 100,
    'path' => CACHE . 'long' . DS,
));
