apache error saying permission denied.

i think www-data user dont have permission how could i resolved this?

error is

sh: /var/www/esm/symfony: permission denied

Check the permissions of the `symfony` file in your symfony root (`/var/www/esm`) — Grad van Horck, Sep 02 '11 at 09:55

You should look in the directory where your script is.

Use ls -la to show all files in the folder and their permissions (to execute php script file must have at least x bit assigned to www-data or its group).

Also all the parent directories up to / MUST have x bit assigned to user/group for apache to be able to change directory to.

Look. You have Tree structured Files system:

/var/www is in /var
/var/www/esm is in /var/www
/var/www/esm/symfony is in /var/www/esm

So www-data user should have the ability to Execute (x bit) all of that directories.

So when in / execute ls -l and look wheter /var has x bit for www-data user or it's group (drwxrwx---) and it owns this directory. When in /var execute ls -l an so on...

You can change permissions to 777 for every directory. But DO NOT use -R key. Just change permissions to the directory only.

i gave sudo chown -R www-data:www-data /var/www/esm/symfony permission still no luck – Roshan Wijesena Sep 02 '11 at 10:09
i checkd the apache error log found sh: /var/www/esm/symfony: permission denied – Roshan Wijesena Sep 02 '11 at 10:13
chown is not enough. check if all the files are readable, writeable and executable. To be shure you can run sudo chmod -R 777 /var/www/esm/symfony. But after fixing the problem for security reasons unused permissions shuld be removed. – s.webbandit Sep 02 '11 at 10:15
due to your apache log www-data can't access directory /var/www/esm/symfony. It means it can't EXECUTE this directory (or some of the parent directories). check x bit – s.webbandit Sep 02 '11 at 10:20

check Ececute bits to all the parent directories. Maybe apache can't simply change directory to /var – s.webbandit Sep 02 '11 at 10:20
im sorry i cant undetstand what should i do to make /var/www/esm/symfony executable – Roshan Wijesena Sep 02 '11 at 10:22

solved the problem for me! I'm using php-fpm and running it from an nginx server. just chmod 777 all directories up to your script! – jcfrei Nov 09 '11 at 11:44
