Tutorials/Server startup script

This is an example of possible Minecraft server startup and maintenance script for GNU/Linux distros.

Pre-Requisites
Screen package must be installed. On CentOs and Red Hat-based distributions: yum install screen On Debian based systems such as Ubuntu: apt-get install screen

Download
To download the script with wget, run the following (WATCH OUT SCRIPT NEEDS WORK): wget -O minecraft "http://minecraft.gamepedia.com/Tutorials/Server_startup_script/Script?action=raw"

Requirements

 * screen

Installation
Use your favorite editor to create file called minecraft in /etc/init.d/ and paste the script above in that file.

Edit the USERNAME and MCPATH -variables according to your setup. If you use a wrapper script, change INVOCATION to start it instead of starting the server directly.

Make sure the newly created file has required permissions You can set the permissions by running: chmod a+x /etc/init.d/minecraft

Then run (on Debian-based distributions) update-rc.d minecraft defaults

Starting with Debian 6.0, the insserv command is used instead, if dependency-based booting is enabled: insserv minecraft insserv will produce no output if everything went OK. Examine the error code in $? if you want to be sure.

On CentOs and RHEL(Redhat enterprise Linux) You will need to add the process into the chkconfig list chkconfig manages startup scripts under systemd chkconfig --add minecraft To check if the process is done correctly use the ntsysv command keep scrolling until you see the minecraft process if you don't repeat the the chkconfig command. to add required symbolic links. Note: your system will most likely warn you that the script does not meet all requirements. The script will however work.

You can also setup an entry in your crontab to backup the server. A sample crontab to backup every half hour on the hour, and 30 minutes into the hour:

crontab -e and add this 0,30 * * * * /etc/init.d/minecraft backup
 * Using the user account you want the work done under, run:

If the above attempt went poorly because you do not know how to use vi, try: VISUAL=/usr/bin/nano crontab -e

Uninstall
(In debian based GNU/Linux distribution) update-rc.d -f minecraft remove (In CentOs/RHEL) chkconfig --del minecraft

Usage
The script may be invoked via the following command on most systems, where "(command)" will be "stop", "start", "restart", or any of the other options it supports. /etc/init.d/minecraft (command) On most RedHat- or Debian-based distribution where the `service` command is available, it should be invoked as: service minecraft (command) To view the screen, use: screen -r

To exit the screen, use: CTRL+a+d

Extra information
If you still want to view the live log file, use this command in the server directory. tail -f logs/latest.log
