Run FastCGI as user, not root.
After reading this, why isn't the example in this wiki set to use the "http" user instead of root.
In step 3 for PHP
the folder /srv/http/nginx does not exist. It should be /usr/share/nginx/http shouldn't it?
systemd fails to start php-fpm with settings in this article
systemd gave error "Failed to get D-Bus connection". To fix, change the following in /etc/php/php-fpm.conf :
;error_log = log/php-fpm.log
error_log = /var/log/php-fpm.log
Not sure if this is confirmed, but seems to be common. Source: Installing Nginx With PHP5
Does anybody with wikiskills want to make the changes? I am new to wiki editing.
