# Minecraft
|
|
|
|
Self-host one or multiple servers.
|
|
|
|
## Setup
|
|
|
|
### Whitelist
|
|
|
|
#### Method 1: Docker
|
|
In the `itzg/minecraft-server` env vars in docker, add the following to enable and configure whitelist.
|
|
```
|
|
ENABLE_WHITELIST: "TRUE"
|
|
WHITELIST: "player1,player2,player3"
|
|
```
|
|
Note: The whitelist is additive, so if you set it to `[player1]` and later `[player2,player3]`, you'll end up with a whiltelist accepting all 3 players.
|
|
|
|
Edit the whitelist in `whitelist.json` in the server directory.
|
|
|
|
#### Method 2: Manual
|
|
After first time startup set `enforce-whitelist=true` in `server.properties`.
|
|
|
|
Then, create `whitelist.properties` in the server directory with the following contents:
|
|
```
|
|
[
|
|
{
|
|
"uuid": "player_uuid",
|
|
"name": "player_username"
|
|
}
|
|
]
|
|
```
|
|
|
|
#### Method 3: In Game
|
|
After first time start go into `server.properties` and set `enforce-whitelist=true`.
|
|
Add users via server commands (`whitelist add NAME`).
|
|
|
|
#### Plugins/Mods
|
|
|
|
### Plugins
|
|
SinglePlayerSleep: `https://www.spigotmc.org/resources/singleplayersleep.68139/`
|
|
Dynmap: `https://www.spigotmc.org/resources/dynmap%C2%AE.274/`
|
|
NoEndermanGrief: `https://www.spigotmc.org/resources/no-enderman-grief2.71236/`
|
|
ajLeaderboards: `https://www.spigotmc.org/threads/ajleaderboards.471179/`
|
|
|
|
#### Updating Plugins
|
|
It's very easy, just obtain the new jar file for the updated plugin, stop server and swap old jar in `plugins/`.
|
|
|
|
Most plugins should not need to regenerate their data, so you can leave it as is.
|
|
|
|
## Maintenance
|
|
|
|
### Backups
|
|
Take backups periodically, we got griefed once and only survived because of a backup.
|
|
|
|
Create Tar archive:
|
|
```
|
|
cd location_of_mc_files
|
|
tar -czvf ~/1970.01.01-world-backup.tar.gz world world_nether world_the_end server.properties whitelist.json spigot.yml
|
|
```
|
|
And move to a safe place.
|
|
|
|
### Periodic Restarts
|
|
You might want this because the JVM might start hitting memory limits if too much is going on.
|
|
|
|
You can configure scheduled restarts by configuring `crontab` to periodically restart the container.
|
|
Edit crontab: `sudo crontab -e`
|
|
Add: `0 2 * * * docker restart minecraft-2023 minecraft-creative`
