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:

screen -S minecraft /home/user/MCMA2_Linux_x86_64

or

cd /home/user
screen -S minecraft ./MCMA2_Linux_x86_64

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

ssh user@localhost -pXXXX
screen -ls
screen -xr minecraft

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

CTRL + A, 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.

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

The /sethome command successfully sets a players home point, but sleeping in their bed does not. - To investigate
On death, players spawn back at original spawn instead of their home. - To investigate

Respawn at home instead of spawn

Change this:

1. 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

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'}

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

Security

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

/seen playername

Log everything:

Install Hawkeye.

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)

Tools

ASCII SSH Bukkit Menu (via screen)
Init script

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.
