Enabling

Nginx does not start on its own. To get Nginx running, type:

systemctl start nginx
systemctl enable nginx

Firewall

If you are running a firewall, run the following commands to allow HTTP and HTTPS traffic:

firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload

Create some users

Its safer to create another user to own the directories which is not the owner of the Nginx process.

groupadd www-data
useradd -g www-data -s /sbin/nologin -M www-data

SELinix

If the port or top level directory is changed then the following lines need to be added.

setsebool httpd_can_network_connect on –P
chcon -Rt httpd_sys_content_t /var/www/wordpress
semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/wordpress(/.*)?"
restorecon –R –v /var/www/wordpress
