i have install lampp 1.8.1 in /opt/lampp.Everything is working fine.

i added my current user as owner to the htdocs folder so that i can write to htdocs folder.

then i created my symfony2 project. everything worked fine and i was able to run the configuration page properly.

but when i cleared the cache using command

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

the cache gets cleared but then there is permissions issue. when i try to access the same configuration page as before it gives me an error in browser:

" RuntimeException: Failed to write cache file "/opt/lampp/htdocs/Symfony/app/cache/dev/classes.php"."

but then when i change the permissions of the cache folder again using :

sudo chmod -R 777 app/cache

the page is again displayed properly

I dont want to change permissions everytime after clearing the cache. Is there a solution or am i doing something wrong?

What are the app/cache permissions and ownership ls -l app/cache after you clear the cache? – Richard Ayotte Feb 23 '13 at 1:39

See "Setting up Permissions" in My preferred way in Ubuntu is setfacl, it works (just need to install a package first time):

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

Do sudo apt-get install acl if there is no command setfacl on your host – userlond Oct 3 '15 at 4:02

if user don't have root privileges correct is

su root 
export user="changeToYouUsername"

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

this example

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

work only if current user have root and this is web log user (if we do it from root account - persmissions fail - it use $whoami as user name
