403 after changing root, but permissions look correct

I’ve been struggling with this for a few hours.

I installed nginx 1.4.6 on Fedora 20. The test page displayed fine. I
changed the root, leaving all other configuration the same, and I get a
403
Forbidden error.

If I look at the permissions for the original test page and the new
page,
they appear identical.

Working test page:
namei -om /usr/share/nginx/html/index.html
f: /usr/share/nginx/html/index.html
dr-xr-xr-x root root /
drwxr-xr-x root root usr
drwxr-xr-x root root share
drwxr-xr-x root root nginx
drwxr-xr-x root root html
-rw-r–r-- root root index.html

Not working:
namei -om /var/www/html/index.html
f: /var/www/html/index.html
dr-xr-xr-x root root /
drwxr-xr-x root root var
drwxr-xr-x root root www
drwxr-xr-x root root html
-rw-r–r-- root root index.html

The error log seems to be what I would expect as well:
2014/03/23 12:45:08 [error] 5490#0: *13 open()
“/var/www/html/index.html”
failed (13: Permission denied), client: XXX.XX.XXX.XXX, server:
localhost,
request: “GET /index.html HTTP/1.1”, host: "
ec2-XXX-XX-XXX-XXX.compute-1.amazonaws.com"

The Nginx config has “user nginx” - I tried using root and it made no
difference. I also made user ngnix the owner & group of the files, but
that
didn’t work. If I move the index file from /var/www/html to
/usr/share/nginx/html (the test file location) it works fine making me
suspect the path, but as I said, permissions appear correct.

Any help would be very much appreciated. Thanks!

I’ve included the config file below just in case:

}

Turns out this was my fault. I was using “sudo service nginx start”
instead
of just “sudo nginx.”

Having just had a similar problem with migrating a MySQL database, I
suggest that you check whether SELinux/Apparmor is running.

Why prople think it’s ok to use a program that can be switched off in an
instant to improve their ‘security’ is and always will be a mystery to
me!

Cheers,

Steve
