Is it possibe to have a small Web Server on My Cloud?

I’ve stopped using Apache2, my Apache2 config file is now per WD’s default untouched. IIRC you need to setup in the conf.d instead because of WD’s settings. Also if you do this you also need to include all WD’s config file e.g. the rewrites else the Dashboard will break.

What kind of sites you’re running on the Ubuntu that you want to migrate to MyCloud? And why do you need Bind9? You can run virtualhosts without Bind9. I suggest you switch to Nginx altogether, refer to my mods here: [APP] WebHosting for firmware V4+ (10/2015)
