permissions error running Console/cake

I'm trying to run the cake console application for the first time. From the cake app folder I am running Console/cake then I get the following output

PHP Warning:  SplFileInfo::openFile(/var/www/virtual_host.com/public_html/app/tmp/cache/persistent/myapp_cake_core_file_map): failed to open stream: Permission denied in /var/www/virtual_host.com/public_html/lib/Cake/Cache/Engine/FileEngine.php on line 314

I tried modifying Config/core.php with the following based on this other SO question

Cache::config('_cake_core_', array(
    'engine' => $engine,
    'prefix' => 'cake_core_',
    'path' => CACHE . 'persistent' . DS,
    'serialize' => ($engine === 'File'),
    'duration' => $duration,
    'mask' => 0666
));

Cache::config('_cake_model_', array(
    'engine' => $engine,
    'prefix' => 'cake_model_',
    'path' => CACHE . 'models' . DS,
    'serialize' => ($engine === 'File'),
    'duration' => $duration,
    'mask' => 0666
));

but it didn't change anything.

Anyone know what permissions I need to change? Is it normal to need to change the permissions on a clean install? (except for app/tmp I know that's normal)

回答1:

make the ownership DevinCrossman:www-data of your whole cake directory sudo chown -R DevinCrossman:www-data . while standing in the root of the vhost.

the webserver (member of www-data) needs to be able to write in app/tmp

回答2:

The files in app/tmp are created with mode 664, so users belonging to www-data (or the group Apache runs with) are allowed to change them. file-permissions cache

So running:

sudo adduser mich www-data
newgrp www-data

solved the problem for me.

HTH

回答3:

Maybe should also

sudo adduser www-data mich

so that cache files created by mich can be accessed by www-data
