Recursive write permissions on files and folders: Prestashop installation

Question

I am trying to install Prestashop in my Linux machine. But it says

Recursive write permissions on files and folders:
~/config/
~/cache/
~/log/
~/img/
~/mails/
~/modules/
~/themes/default/lang/
~/themes/default/pdf/lang/
~/themes/default/cache/
~/translations/
~/upload/
~/download/
~/sitemap.xml 

And I got some red cross marks in it. But I gave a 777 permission to the prestashop directory chmod -R 777 prestashop.

Answer 1

I know this is old but best way is to do the following:

sudo chown -R user:www-data /var/www/prestashop
sudo chown g+w -R /var/www/prestashop

The above gives user access make sure you add user to www-data group 1st g+w gives write permissions to group

Answer 2

Change the ownership of the files under Prestashop directory to allow web-server user to write

sudo chown -R www-data:www-data /var/www/prestashop

Disable SELinux (better to configure SELinux to allow prestashop directory to do his stuffs)

setenforce 0 

Answer 3

On Ubuntu Linux: you need to give the apache web server (whose user name and group name is www-data) permission to do stuff on the files in the filesystem under prestashop.

# cd /var/www/prestashop
# chown -R www-data *
# chgrp -R www-data *

Refresh the prestashop install page and that particular problem should be gone.
