Behind a reverse proxy

myMPD could be hosted behind a reverse proxy to add features like http2 and authentication.

Configure myMPD to disable ssl and listen on localhost on port 8080.

printf "false" > /var/lib/mympd/config/ssl
printf "8080" > /var/lib/mympd/config/http_port
printf "127.0.0.1" > /var/lib/mympd/config/http_host

The reverse proxy should be configured to:

In this examples myMPD is proxied behind the path /mympd.

Nginx

location /mympd/ {
  proxy_pass http://127.0.0.1:8080/;
  proxy_redirect / /mympd/;
}

Apache

Basic setup with proxypass

To access mympd behind apache2 enable following modules, e.g. with a2enmod:

Add the following to a existing or a new virtual host:

ProxyRequests Off 
ProxyPreserveHost on
ProxyVia On

ProxyPass /mympd/ws/ ws://127.0.0.1:8080/ws/

Redirect /mympd /mympd/
ProxyPass /mympd/ http://127.0.0.1:8080/
ProxyPassReverse /mympd/ http://127.0.0.1:8080/

Basic Password Authentication

To add basic password authentication create a new htpasswd file sudo htpasswd -c <path/to/htpasswd/file> <username to access mympd>

Or append an existing htpasswd file sudo htpasswd <path/to/htpasswd/file> <username to access mympd>

for example: sudo htpasswd -c /etc/apache2/.htpasswds mympd

Then add the following to your mympd Location in your apache virtualhost configuration file

AuthType Basic
AuthName "Authentication Required" # or add any type of identifier you prefer
AuthUserFile <path/to/htpasswd/file> # for example /etc/apache2/.htpasswds
Require valid-user

for example:

<Location "/mympd/">
  AuthType Basic
  AuthName "Authentication Required" # or add any type of identifier you prefer
  AuthUserFile <path/to/htpasswd/file> # for example /etc/apache2/.htpasswds
  Require valid-user
</Location>

See https://wiki.apache.org/httpd/PasswordBasicAuth for more information

Simple Access Control

To limit acces to mympd to the local network, add the following to the location directive adjusting for your own network:

Require host localhost 
Require ip <ipaddress>
Require ip <ip range/netmask> # ex 192.168.1.0/24

See https://httpd.apache.org/docs/2.4/howto/access.html for more information
