## Command Permission Control

You can [edit the system environment settings](/en/deploy/settings.md) to set permissions for command nodes. When a command is initiated, if the user's permission level (administrator is `2`, regular user is `1`) is greater than or equal to the command node's permission level, the command can be successfully executed.
