kawaiiwolf Posted January 20, 2012 Posted January 20, 2012 Useful for anyone who wants to run their Tekkit server on a linux machine. It's a modified script from https://github.com/lhutton/minecraft-server-init-script and http://www.minecraftwiki.net/wiki/Server_startup_script. It requires rsync and screen and of course your latest java package. On a debian based system you can install it with update.rc <scriptname> defaults where <scriptname> is whatever is whatever you call this file. #!/bin/bash # User editable variables: # Always include the trailing slashes on directories! MINECRAFT="Tekkit.jar" # Name of your server jar file. This script supports vanilla and craftbukkit. MCPATH="/var/minecraft/server/" # Directory on disk of your MC server. Make sure your MINECRAFT jar file is located here. ARGS="-Xincgc -Xmx1024M -Xms1024M -jar" # Standard arguments for the minecraft server jar. USER="minecraft" # User your minecraft server runs under. BACKUPDIR="/var/minecraft/backups/" # Directory for backup tar files. # Various programs this script calls # Setup for Debian by default, you may need to update the location of these for other distros. JAVA="/usr/bin/java" SCREEN="/usr/bin/screen" DATE=$(date +%m-%d-%Y-%H:%M) TAR="/bin/tar" RSYNC="/usr/bin/rsync" # RAM Disk settings. # Don't use this if you don't know what you're doing! # See the README for me info RAMDISK=false # Set to true if you want to use a RAM disk, false to run from a hard disk. See README first. RAMDISKDIR="/path/to/ramdisk/" # The path where your RAM disk is mounted. already_running(){ if pgrep -u $USER -f $MINECRAFT > /dev/null then return 1 else return 0 fi } run_as() { WHOAMI=`whoami` if [ "$WHOAMI" == "$USER" ] then bash -c "$1" else su - $USER -c "$1" fi } start() { already_running if [ "$?" == "1" ] then echo "Minecraft already running ..." else if [ $RAMDISK == "true" ] then echo "Copying files to RAM Disk ..." setup_ramdisk echo "Starting $MINECRAFT ..." run_as "cd $RAMDISKDIR && $SCREEN -dm -S minecraft $JAVA $ARGS $MINECRAFT" sleep 7 else echo "Starting $MINECRAFT ..." run_as "cd $MCPATH && $SCREEN -dm -S minecraft $JAVA $ARGS $MINECRAFT" sleep 7 fi already_running if [ "$?" == "1" ] then echo "$MINECRAFT started." else echo "Error, $MINECRAFT could not be started.

THIS SCRIPT IS NOT WARRANTIED TO WORK PROPERLY OR AT ALL. PROVIDER(S) (i.e. me) ARE NOT LIABLE FOR ANY DAMAGE YOU MIGHT INVOKE UPON YOUR OR ANYONE ELSE'S MACHINE. If you have any questions as to what's going on in the script I'd be glad to help but the commands are fairly self-explanatory: Usage: minecraft-server {start|restart|save-all|backup|writetodisk|stop|command/cmd} The "cmd" code of is great value since it passes commands directly to the console without having to manually invoke the screen. Lets say you want to whitelist someone without having to edit the file/restart the server or promote a user within minecraft to op. You just type the command from your linux prompt/ssh session: /etc/init.d/minecraft-server cmd whitelist add SomePlayerName
milligannn Posted February 23, 2012 Posted February 23, 2012 Any chance you could tell me how to set this up? I connect to my dedicated server through a vnc server. its running debian and i dont understand how to use this to allow tekkit to install. please help? :)
kawaiiwolf Posted February 23, 2012 Author Posted February 23, 2012 This is a script to help automate running the server, not to install it. Usually to install you just untar the server.
pieiscool32 Posted February 23, 2012 Posted February 23, 2012 Well I used McMyAdmin, am I going to need this?
nukeguy19 Posted February 29, 2012 Posted February 29, 2012 im still not entirely sure wat the script does. is it possible to just use a script like the one for windows, like a .bat file?
kawaiiwolf Posted February 29, 2012 Author Posted February 29, 2012 im still not entirely sure wat the script does. is it possible to just use a script like the one for windows, like a .bat file? Yes, this is just a much more sophisticated version of that, handling things in a cleaner and more optimized way for a linux client. It runs with a bunch of command line options as well. Starting, stopping, opping a player/giving an item, all done through the interface (./script start, ./script start, ./script cmd op player, ./script cmd give player 1 64) etc.
Grasfer Posted March 1, 2012 Posted March 1, 2012 im still not entirely sure wat the script does. is it possible to just use a script like the one for windows, like a .bat file? Make a new file called start in Tekkit.jar folder, then chmod +x start Then you add this into the file with your favourite editor #!/bin/bash java -Xincgc -Xmx1536M -Xms100M -jar Tekkit.jar nogui and then you just ./start when you saved your file. If you want the server upp all time, type screen first then you ./start it. ctrl+alt+d to get back to your normal screen and the server should be up until it crash or you reboot server :)
