How to Set Up BlueMap or Dynmap on Your Minecraft Server

Install the plugin

Maps need Paper or Purpur (Village or Kingdom). On Mods → Plugins, search for BlueMap or Dynmap, add it, and click Apply to server. See How to install plugins.

Add a plugin port

1. Open your world and go to Network.
2. Click Add a port. The panel gives you a port number and a link.
3. Each world can have up to 3 plugin ports.

Put the port in the config

Open Files and edit the plugin's config. Set the web port to the number from Network, and make it listen on all interfaces (0.0.0.0).

1. BlueMap: in plugins/BlueMap/webserver.conf, set port to your number. In plugins/BlueMap/core.conf, set accept-download: true.
2. Dynmap: in plugins/dynmap/configuration.txt, set webserver-port to your number and webserver-bindaddress to 0.0.0.0.
3. Save, then restart the world once from the Overview.

Open the map

Use the link on Network. The map only answers while the world is online. A sleeping world shows no map until someone joins.
