Server

Minecraft servers allow players to play online with other people. They may either be run on a hosted Minecraft server service, a dedicated server, a VPS or a home machine. This is not a list of servers.

General recommendations

Server requirements

 * The more memory your computer has, the better. It's recommended to have more than 2 GB, that way plenty of ram is left over for the operating system, and you have the possibility of allocating more to the Minecraft server.
 * Minecraft servers, as of 1.0.0, can use multiple cores, so now they won't sit idle.

Server commands and known issues
The server commands page has a list of useful commands.

See the known bugs page for known single/multiplayer issues.

Special note: Atheros and Realtek network adapters are known to not work well with Minecraft in general. If you experience a total loss of internet (requiring a reboot), or constant disconnects, check and see if you have either brand of network adapter installed. If you do, you can try updating the driver for the device directly from the manufacturer. If a driver update does not fix the issue, the general solution is to buy a new adapter (anything from Intel is recommended as a replacement).

Setting up a server

Types of Servers
There are numerous kinds of Minecraft servers, usually distinguished by the level used in them or how players in them are supposed to behave. Many special types of servers rely on the use of map editors.

Survival
Standard servers usually have relatively regular maps, allowing players to build or destroy whatever they want (though griefing is often against servers' rules).

Creative
Usually a server that allows players to make what ever they want, more focused on building and griefing is not allowed.

Roleplay
A server, usually with a normal map, where players are encouraged to take on roles like Mayor, Blacksmith, Cook, and act as them in the game. These servers often attempt to simulate settlement in some foreign land or similar, and require the gathering of resources to build structures. There are generally factions that can be made in these servers.

PvP
A server where players are encouraged to fight versus other players (thus the appellation PvP, meaning Player versus Player). Stealing is sometimes allowed.

Hardcore PvP
A type of server which is like PvP, but fully allows griefing.

Prison
In prison servers, there typically is no wilderness, and player must earn money in order to advance in the prison. There are servers that have freedom at the advancement line, in which there you are released.

Challenge
Usually these servers have some sort of a challenge, such as surviving underwater, or living in a small box with few materials.

Delete Player
If you want to delete a player from the game, you can remove the player's .dat file. Navigate to the Minecraft home directory, open the map folder, open the player's folder, and delete the PLAYERNAME.dat file. This will cause the player to start over at the spawn point with no inventory. The player's changes to the world will be unchanged along with any inventory stored in chests. This will not ban the player that has been deleted.

Edit Player
If you don't want to delete a player completely, but want to remove something from him or move him to a different spot, or even give him an enchanted item, you can edit the PLAYERNAME.dat file with NBTedit simlar to how you would a level save. (Only the player needs to be offline. No server restart needed.)

Creating backups

 * 1) Enter save-all into the console or /save-all in Minecraft (as a server op).
 * 2) Copy the world save file to create the backup. DO NOT MOVE IT! (No server restart needed)

Death messages
Death messages are broadcast to everyone on the server upon a player's death. These messages relate to how the player died and are intended to be humorous. Death messages were added in Beta 1.8 Pre-release.
