Symfony 2 cache clearing issue

Question

My Symfony 2 website has recently been giving me problems when I try to clear the cache. I type the following command in the terminal:

php app/console cache:clear --env=dev

And get the following error:

[ErrorException]                                                                                                                                                                                                                                   
 Warning: rename(/var/www/corpsite/corpsite/app/cache/dev,/var/www/corpsite/corpsite/app/cache/dev_old): Directory not empty in /var/www/corpsite/corpsite/vendor/symfony/src/Symfony/Bundle/FrameworkBundle/Command/CacheClearCommand.php line 74  

So I change the permissions on that file to 777, and re-run the clear cache command, which gives me this error:

  [ErrorException]                                                                                                                                                                                                                         
  Warning: unlink(/var/www/corpsite/corpsite/app/cache/dev_old/twig/6b/e9/4491e41b895786689b86f32f446f.php): Permission denied in /var/www/corpsite/corpsite/vendor/symfony/src/Symfony/Component/HttpKernel/Util/Filesystem.php line 100  

I can get round the problem by deleting the 'dev_old' folder, but I want to solve the problem that is causing the issue.

P.S - I am aware the site is running in dev mode. The site has been live for 10 months and this has never been an issue before.

Any help is appreciated!

Answer 1

You need to get your access rights on both cache & logs folders. To do that, you can follow the indications given here : http://symfony.com/doc/current/book/installation.html#configuration-and-setup

There are several ways, depending on your OS (replace www-data with your apache user):

If it supports chmod +a:

$ rm -rf app/cache/*
$ rm -rf app/logs/*

$ sudo chmod +a "www-data allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs
$ sudo chmod +a "`whoami` allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs

Else, if it supports setfacl (see https://help.ubuntu.com/community/FilePermissionsACLs):

$ sudo setfacl -R -m u:www-data:rwX -m u:`whoami`:rwX app/cache app/logs
$ sudo setfacl -dR -m u:www-data:rwx -m u:`whoami`:rwx app/cache app/logs

Else, put those lines in the beginning of app/console, web/app.php & web/app_dev.php (not recommended):

umask(0002); // This will let the permissions be 0775

// or

umask(0000); // This will let the permissions be 0777

Answer 2

in Symfony3 folders with cache moved from app to var, so the command will be:

$ rm -rf var/cache/*
$ rm -rf var/logs/*
$ sudo chmod +a "www-data allow delete,write,append,file_inherit,directory_inherit" var/cache var/logs
$ sudo chmod +a "`whoami` allow delete,write,append,file_inherit,directory_inherit" var/cache var/logs
