Unable to write cache file

Check that your cache/ and your log/ directories is writable by your web server.

I am sorry I have to reopen this, Fabien, although as a minor bug. It has indeed to do with permissions, but not so trivially, since cache/ and log/ are set to 777 soon after symfony init-project is invoked and no one ever changes it.

It must be something else and it may also depend on php or apache configurations, but it happens right after the init-project and init-app symfony commands on a standard server configuration that is hosting another working symfony project; it may well discourage people from going further with symfony, so I think it deserves a bit of attention from the community.

Activating track_errors and changing "@mkdir" into "@mkdir or die", into the sfFileCache->setCacheDir() method, the 'Permission denied' error keeps coming out.

safe_mode is turned off and open_basedir is set to no value as far as php configuration is considered. (see http://askeet.palomarlab.net/test.php for details)

chmod -Rf 777 cache log

Ok, SELinux was the problem. The server is a FC4 with SELinux turned on.

chcon -Rt httpd_user_content_t [dir]

does the trick.

Turning SELinux off works, too. Maybe a small note in the manual could help.

i got this after reading every informations here my config is correct

i got OpenBSD my log and cache dirs are set to www:www and 777 either to be sure and still the same any help how to resolve this issue

This is not a symfony bug but a particular config issue. Please refer to the forum for problems about installation.

I got this same problem when meta-following the instructions here: http://www.symfony-project.com/content/book/page/project_creation.html

chmoding 777 the cache and log directories wasn't enough. After getting the error I had to go back and chmod -Rf them, presumeably after some part of the process re-created directories in there that didn't have proper permission. None the less, it seems to me that it is just a permission issue caused by removing and recreating the directories.
