How to edit server.properties

The server.properties file controls basic Minecraft server behavior such as MOTD, gamemode, difficulty, player slots, whitelist, online mode, and view distance.

Common files or settings

server.properties
ops.json
whitelist.json
banned-players.json
world/

Open the file manager

Open your server in the VialStack panel, go to Files, and open server.properties in the main server folder.

Edit one setting per line

Change values after the equals sign. For example, use motd=Welcome to my server or max-players=20.

motd=Welcome to my server
max-players=20
difficulty=normal
white-list=true

Save and restart

Save the file, then restart the server so Minecraft reloads the settings.

Quick checks

Back up before changing saves or major settings.
Restart after saving config changes.
If it fails, read the first error in the latest log.
