Minecraft

Currently the server is running 1.4.6-R0.4 Dev for our Minecraft server. We have now updated the plugins to be compatible with 1.4.6

Load Minecraft:

/usr/bin/java -Djline.terminal=jline.UnsupportedTerminal -client -Xmx7132M -jar craftbukkit.jar nogui -d yyyy-MM-dd HH:mm:ss -nojline

Load McMyAdmin:

tmux new-session -t minecraft
cd /home/user
./MCMA2_Linux_x86_64 | tee /var/www/sites/b*.co.uk/logs/ender*.log

If you want to connect from elsewhere to view the above output/console load the screen session:

ssh user@localhost -pXXXX
tmux ls
tmux attach 1 or minecraft

Using CTRL + D will quit screen and close any processes running within it. To exit safely do:

CTRL + B, let go, then press D on it's own.

When downloading a backup from McMyAdmin, it comes in the mcb format. Change it to .zip and you can then unzip it into a folder and restore to the server.

Chat

/tell PlayerName will whisper a message to a player. This option will not show in a console.

/msg PayerName will show it as YourPlayerName -> Me to the other Player but be private

Connection reset [Metrics]

Set opt-out to true in plugins/PluginMetrics/config.yml

This by default is false.

Configuration

Lava

Allowing lava seems to be easiest by creating a group that can do it and then doing:

# Allow lava buckets
[lavabucket]
allow
ignore-groups=Everyone
on-use=notify,log

The below method seems to fail

ignore-perms=worldguard.lavabucket.exempt
ignore-groups=admins,mods,Lava
on-use=deny,tell,notify,log

Current errors

None

Current issues

Enderman do not spawn. Likely issue with a plugin.

Essentials

Command reference

Find players home:

/home playername:home
/home <user>:<name>

Broken:

/home user:

Get user's coordinates

If you have Essentials, use /getpos PlayerName

Kill specific mob/s

/killall MobName (e.g. Blaze)

Mail players

/mail send FullPlayerName Message

To read the mail, do /mail read
To clear the mail, do /mail clear

Respawn at home instead of spawn

Change this:

When users die, should they respawn at their first home or bed, instead of the spawnpoint?

respawn-at-home: false

to

respawn-at-home: true

Set players home

WIP

Teleport player to you

/tpohere playername

Teleport to coordinates

/tppos x y z

Teleport to player

As OP, /tpo playername

As player, /tpa playername

Fixed errors

NoSplosion will cause Endermen to NOT spawn:

"Disables all explosions vanila or mods (tekkit etc...) and fire from destroying blocks as well as endermen from spawning. All explosions and fire still damage players but do not damage the environment."

Outdated version, install up-to-date version: http://dev.bukkit.org/server-mods/nocheatplus/

Install Feed The Beast on a Unix server

Add a user and make a directory specifically for the mod, e.g.:

add user ftb
mkdir server
cd /home/ftb/server
su ftb

Then do:

tmux new-session -n NameTheSession
su user
cd ~/server
wget http://www.creeperrepo.net/direct/FTB2/6ce418a51b200ece8cb3c509ba9e094a/modpacks%5EUltimate%5E1_0_1%5EUltimate_Server.zip
mv modpacks^Ultimate^1_0_1^Ultimate_Server.zip Ultimate_Server.zip
unzip Ultimate_Server.zip
vim ServerStart.sh

Edit the values as you see fit.

chmod +x ServerStart.sh
./ServerStart.sh | tee ftb.log

It will error out if you're already running a Minecraft server on the default port 25565. If it does, do CTRL + C. To change this,

vim server.properties

Set the server-port to something that is not 25565. Then make sure the user:group ownership is correct on the server folder and all files and directories below it.

./ServerStart.sh | tee ftb.log

CTRL + B then d to quit the tmux session.

Errors

If you get something like below, you likely need to disable some mods (for me it was mods/railcraft.jar and mods/MineFactoryReloaded.jar):

[SEVERE] [ForgeModLoader] Detected leaking worlds in memory. There are 4 worlds that appear to be persisting.
A mod is likely caching the world incorrectly
2013-04-23 15:54:59 [SEVERE] [ForgeModLoader] The world 7debb392 (world) has leaked.
2013-04-23 15:54:59 [SEVERE] [ForgeModLoader] The world 3e6abeb4 (world) has leaked.

Load MCMyAdmin and Minecraft on server start

ssh -p port user@localhost
crontab -e

Press insert and add:

@reboot screen -dmS minecraft /home/mc/MCMA2_Linux_x86_64

Then do:

:wq

You can then if you wish do:

exit
touch /etc/init.d/minecraftd ; chown user:user /etc/init.d/minecraftd
vim /etc/init.d/minecraftd

Lock chests

Use Lockette. To snoop in chest and to do this without message, edit this file:

/home/user/Minecraft/plugins/Lockette/config.yml

And edit the following:

allow-admin-snoop: true
broadcast-snoop-target: ''

Kill all MCMA processes

ps aux|grep MC|grep x86|awk {'print $2'}

Results of the above command.

for a in `!!`
for a in `ps aux|grep MC|grep x86|awk {'print $2'}`
> do
> kill -9 $a
> done
ps aux|grep MC|grep x86|awk {'print $2'}

McMyAdmin Licence Key Recovery

McMyAdmin help in console command:

/?

Migrate from one *nix server to another

scp / rsync the data in the Minecraft directory across. Then do:

apt-get install unzip
apt-get install openjdk-7-jre openjdk-7-jdk
cd /usr/local
wget http://mcmyadmin.com/Downloads/etc.zip
unzip etc.zip

Go to serverIPaddress:8080 in your browser. To login, check the details in McMyAdmin.conf. To change the password you need to stop McMyAdmin:

/quit in console

The file stores the password as MD5, to convert your password use this: http://www.md5hashgenerator.com/index.php

Multiverse

Create new world

/mv create worldname TYPE

Hide world name in chat

In /plugins/Multiverse-Core/config.yml set prefixchat: 'false' to prefixchat: 'true'

Import backup of world

Delete the uid.dat file in the <worldname> folder before importing.

Set world alias and name

Set alias:

/mvm set alias newname oldname

Set world name

It is best to backup and remove the world, change the folder name and re-import it using /mv import foldername WORLDTYPE, then add it to plugins/Multiverse-Core/worlds.yml

Note: Set original world to be zworld. world is an older backup before zzd with several users homes pasted in.

Teleport player to another world

/mv tp them worldname

This portal leads nowhere!

Do /mvlist

You will need to load your worlds that link together (e.g. world and world_nether)

Permissions

If you use PermissionsBukkit with McMyAdmin, if you make a change you normally need to restart the Minecraft server to get it to see the changes.

Security

To check when a player was last online, their IP address, what world they are in, do:

/seen playername

Useful:

screen -xr mcmonitor
CTRL A + D
screen -xr mysqlmcmon

cd /home/mc/Minecraft
cat server.log | grep "YYYY-MM-DD" | grep User | grep -v indestructible
cat server.log | grep User | grep -v 'indestructible\|fell from a high place'

Create the database:

mysql -p
create database hawkminecraft;
show databases;
use hawkminecraft
show tables;

This may be empty. If so (more than likely), log into your minecraft server and do /reload. Then go back into MySQL:

use hawkminecraft
show tables;
+-------------------------+
| Tables_in_hawkminecraft |
+-------------------------+
| hawk_players            |
| hawk_worlds             |
| hawkeye                 |
+-------------------------+
select * from hawk_players;
select * from hawk_worlds;
select * from hawkeye;
quit

And you can now do /hawk in game. To check a block, do /hawk tool , then left click a block and it will show you the block information.

Get table structure and players

desc hawkeye; select * from hawk_players;

Look at logs

select * from hawkeye ORDER BY data_id DESC LIMIT 100000;

See region information

/region info area

It should output something like:

Region: area, type: shape, Priority: X
Flags: use: ALLOW, mob-spawning: DENY (OR ALLOW)
Bound: (x) (z)

Set flyspeed

Default is 1

For yourself:

/flyspeeed 2

For others:

/flyspeed 2 playername

Update CraftBukkit

Stop the server, then do:

mv craftbukkit.jar versioncraftbukkit.jar
wget http://dl.bukkit.org/latest-rb/craftbukkit.jar

Or download the development/beta build and do:

mv craftbukkit-dev.jar craftbukkit.jar

Start the server

Log out and back into MCMyAdmin.

World Edit

Place .schematic files in /home/user/Minecraft/plugins/WorldEdit/schematics

Import them by doing:

//schematic load filename

Then you can do //paste in Minecraft to paste it into the world where you are.

World Guard

To protect an area, do:

//wand

Then click the first position then the second position with the wooden axe.

If you only do one layer, you can do //expand to go up or down, e.g.:

//expand UpValue DownValue up
//expand 10 0 up

This would expand up 10 blocks from the single layer but do 0 down.

Then do:

/region define newnameforarea owner

Owner can be left blank.

To get information on the area you just created, do:

/region info newnameforarea

Set flags

To set flags, see this page: http://wiki.sk89q.com/wiki/WorldGuard/Regions/Flags

To stop building and PvP but to allow use, you would do:

/rg flag areaname build deny
/rg flag areaname pvp deny
/rg flag areaname use allow
