Like most games, Minecraft has a built-in mechanism to set authorised MineCraft players as administrators of the server. These are known as OP’s or operators which is a generic term used to call people who manage IRC servers, game servers or online forums.
An operator is one of the highest level of access any player can have on a Minecraft server
Managing OP Players
You can assign OP players by either use of your control panel, by console commands, or even ingame commands (by other already op-ed players)
Managing OP in MultiCraft
Firstly, ensure you’re on the control panel for your Minecraft server. Under the
Players page, you will find an
OPs tab. Any players added to this list will automatically be op-ed by our system. You may need to restart your server after changing players.
Assigning OP via Console or ingame commands
Using the command
/op you can assign or remove ops.
/op <playername> – to add a player as OP status
/deop <playername> – to remove a player from OP status
When using the web-based console, be sure to drop the
/ from the start of the command
Since the 1.7.10 snapshot release (13w19a), Operator Permission Levels were introduced into Minecraft, to give server administrators much more granular control over operator permissions. Each permission level is assigned various commands, and inherit all commands from the previous level. For example, a level 3 operator also has access to the commands from both level 2, and level 1. The highest possible operator permission level, is 4.
|Level||Highest level of access|
|Level 1||Ops can bypass spawn protection. No commands are assigned to this level of operator.|
|Level 2||Ops can use
|Level 3||Ops can use
|Level 4||Ops can use
