Permission problems running WordPress on Nginx

Question

I recently set up a new droplet using the “LEMP on 14.04” stack on DO, and I’m experiencing some issues with permissions for when uploading images or updating plugins in the WordPress admin. I figure this has to do with ownership of the folders. The plugins and uploads folders are currently set to 755. I have one user and group on the server, both named root. How would I easily solve this - adding a secondary group / user and then granting new ownership of the folder?Setting any of the folders to 777 makes everything work but I don’t want that for security reasons.

The issue is likely because your files are owned by root. Your nginx process would be running as the user “www-data” and so it would not have the needed access to these files. You can change the ownership of your files using the command:

chown -Rf www-data:www-data /usr/share/nginx/html

Using the path to your web root if it is different from the one shown.

Simply put, you need to have nginx run PHP-FPM.

You can look at how to do that by going to the config part in this how-to:

Basically, the part you want:

Edit /etc/php-fpm.d/www.conf
change user and group:

user = nginx
group = nginx

restart PHP-FPM, then you can just run this on your folder (Change “/path/to/your/website” to the actual path):

cd /path/to/your/website; find . -type d -print0|xargs -0 chmod 755; find . -type f -print0|xargs -0 chmod 644; chown nginx:nginx * -R
