Startup & Variables

The Configuration tab controls how your server boots: the startup command, the variables the template exposes (game version, memory, extra flags), and a form editor for the server’s config files.

Prerequisites

Section titled “Prerequisites”
  • A server you can access, with the server.update permission to change the startup command, variables, and template config files.
  • A restart after the change — most games read these values only at boot.

Change a startup variable

Section titled “Change a startup variable”
  1. Open your server’s Configuration tab and find the Startup variables section.
  2. Edit the value. Variables render as a text box, a number box, or a toggle depending on their type; required variables are marked with *.
  3. Select Save. A Reset button appears while you have unsaved changes and discards them.
  4. Restart the server — startup variables only take effect at boot.

Values are validated as you type: a bad number, a missing required value, an out-of-range value, or a value outside the allowed list is flagged under the field, and the save is rejected with the offending fields marked.

Change the startup command

Section titled “Change the startup command”
  1. In Configuration, edit the Startup command field. Templates use placeholders such as {{MEMORY}} and {{PORT}} that the panel fills in at boot.
  2. Select Save.
  3. Select Reset to default to restore the template’s original command. When your command differs from the template, the template default is shown below the field as a clickable link that restores it.

Edit config files

Section titled “Edit config files”

The Config files section loads the files the template declares (for example server.properties) and lets you edit them in a Form or Raw view, with a search box to jump to a key. Select Save config to write the file. Files not declared by the template are edited through Files instead.

Rules

Section titled “Rules”
  • Only change what you understand. A bad startup flag or config value is the most common self-inflicted reason a server enters a boot loop.
  • Memory variables must stay within the server’s allocated limits — the game cannot use more than the server owns.
  • If the server worked before your change and boot-loops now, revert the last edit first and ask questions later.

Templates define what is editable

Section titled “Templates define what is editable”

Which variables exist, their defaults, and their allowed values come from the server’s template (set by your administrator). If a template exposes no startup variables, the section stays empty. If you need a variable the template does not expose, ask your administrator.
