It also works really well with the browser extension and mobile apps. Assuming you have a Heimdall server for example, your configuration file may be created as follows: And, assuming that the server is located at, populate it as follows: Now, nginx only looks at /usr/local/etc/nginx/nginx.conf when inspecting configuration, so we have to tie everything we’ve just done in there.

The server block redirects all HTTP traffic to HTTPS to ensure that the SSL/TLS configuration we set up is being used, and the include statement imports the server blocks from all of the virtual domain configuration files. Since the rest of this procedure involves making some decisions about whether or not to use SSL/TLS termination, we’ll discuss it here.
