Setting Permissions

I do not set any folder or file to 777.

In order that I, as a user, can edit files, while still allowing www-data to add, edit, delete files, I add my user to www-data and vice-versa. Modify below to fit your needs.

sudo usermod -a -G www-data $USER
sudo usermod -a -G $USER www-data

After doing this, you need to log out and then back in. Then I set ownership of website path. From the Pu-239 path.

sudo chown -R $USER:www-data ../Pu-239/

Then, I run set_perms.php to set the remaining permissions correctly.

sudo php bin/set_perms.php
