is a server-management script for UNIX and Linux powered Minecraft servers.

Features include:

* Run multiple Minecraft worlds.
* Start, stop, and restart single or multiple worlds.
* Create, delete, disable, and enable worlds.
* Includes support for additional server types: [Forge]
(http://www.minecraftforge.net/),

[SpigotMC](http://www.spigotmc.org/wiki/spigot/), etc.
* Users automatically notified of important server events.
* LSB and systemd compatible init script,
allows for seamless integration with your server's startup and shutdown
sequences.
* Map worlds using the [Minecraft Overviewer](http://overviewer.org/)
 mapping software.
* Automatically backup worlds, remove backups older than X days,
and restart worlds.
* Update the server and client software automatically.
* Send commands to a world server from the command line.

## Prerequisites for installation
Ensure that you have done the following before installing MSCS:

### Required Programs
We've made an attempt to utilize only features that are normally installed in
most Linux and UNIX environments in this script. However, there may be a few
requirements that this script has that may not already be in place:
* Java JRE     - The Minecraft server software requires this.
* Perl         - Most, if not all, Unix and Linux like systems have this
                 preinstalled.
* libjson-perl - Allows the script to read JSON formatted data.
* Python       - Required by the Minecraft Overviewer mapping software.
* GNU Make     - Allows you to use the Makefile to simplify installation.
* GNU Wget     - Allows the script to download software updates via the
                 internet.
* rdiff-backup - Allows the script to efficiently run backups.
* rsync        - Allows the script to efficiently make copies of files.
* Socat        - Allows the script to communicate with the Minecraft server.
* Iptables     - Although not explicitly required, a good firewall should be
                 installed.

If you are running Debian or Ubuntu, you can make sure that these are
installed by running:

    sudo apt-get install default-jre perl libjson-perl python make wget rdiff-backup rsync socat iptables

### Configuring the firewall / NAT
If you have a firewall installed on your computer, or a router using NAT
installed in your network, you will need to route some ports to your server.
Instructions on how to accomplish this are beyond the scope of this document,
but here are some things you will need to know:
* The default port for the Minecraft server is: `25565`.
* If you wish to run multiple world servers using this script, you may
  want to open a range of ports (for example `25565 - 25575`).
* If you are using [BungeeCord](http://www.spigotmc.org/wiki/bungeecord/),
  you will most likely need to only open the default port: `25565`.

See the [iptables.rules](iptables.rules) file for a very basic set of rules
that you can use with the Iptables firewall.

### Mapping software
The script uses the [Minecraft Overviewer](http://overviewer.org) mapping
software to generate maps of your worlds.  Minecraft Overviewer is a
command-line tool for rendering high-resolution maps of Minecraft worlds. It
generates a set of static html and image files and uses the Google Maps API to
display a nice interactive map.

Please see 

## Installation
### Downloading the script
The easiest way to download the script is to make a clone of the [git
repository](https://github.com/MinecraftServerControl/mscs.git).
You must have git installed first. To install git:

    sudo apt-get install git

Then:

    git clone https://github.com/MinecraftServerControl/mscs.git

Note that it will be downloaded into the current directory which you are
working in.

##### Other ways to download

* Get the latest stable [release]
(https://github.com/MinecraftServerControl/mscs/releases).

* Get the development version as a [zip file]
(https://github.com/MinecraftServerControl/mscs/archive/master.zip):

    wget https://github.com/MinecraftServerControl/mscs/archive/master.zip

### Configuration

Navigate to the `mscs` directory that you just downloaded.  Configuration can
be done with the included Makefile in Debian and Ubuntu like environments by
running:

    sudo make install

This will give the user you created in the config (by default, the user is
called `minecraft`) access to write in the `/opt/mscs` folder.

If you get a permission error, please see the [troubleshooting]
(#troubleshooting) section.

#### Manual Configuration
If you wish to configure the script manually, please visit the [wiki page]
(https://github.com/MinecraftServerControl/mscs/wiki/Manual-Configuration).

### Updating MSCS
Periodically Minecraft Server Control Script is updated to address bug fixes
and add new features. The easiest way to fetch the latest update, assuming you
used [the easiest way to install the script](#downloading-the-script), first
`cd` into the folder where you downloaded MSCS. Then, type:

    git pull

You can alternatively use [one of the other methods](#other-ways-to-download)
to download the latest version.  Just `cd` into the folder containing the MSCS
download to continue.

Once you have the latest version of MSCS downloaded, type:

    sudo make update

## Getting started guide
So you successfully installed the script--great!

At first, you probably want to [create a new world](#creating-a-new-world) or
[import an existing world](#importing-an-existing-world) into the script.

Then, you might want to adjust the
[world properties](#adjusting-world-properties), adjust the
[global server properties](#adjusting-global-server-properties), and enable any
other [server software](#enabling-forge-bungeecord-and-other-server-software)
as needed.

### Creating a new world
The command to create a new world is:

    mscs create [world] [port] <ip>

Where `world` is the name of the world you specify,
and `port` is the server port (by default, use `25565`).
`ip` is optional and will be used if you wish to bind a world server to a
specific network interface (e.g. `127.0.0.1` to enforce local access only).

Afterwards, start the server via `mscs start [world]` where `world` is the
name of the world. The world will then shut down because you have to accept
the EULA.

The EULA can be found in `/opt/mscs/worlds/myWorld` where `myWorld`
is the name given to the world you created.

After accepting the EULA simply start the server using the same command above,
and you're all set!

### Importing an existing world

You just need to create a new directory in the worlds folder for the world you
wish to import. Suppose the world you wish to import is called `alpha`, you
would create a new folder in `/opt/mscs/worlds` with the same name as the
world, then copy the data files over to that new directory.

IMPORTANT: make sure the world that you are importing is not currently
running.

If the directory containing the world `alpha` you wish to import looks like
this:

    $ ls
    alpha
    banned-ips.txt
    banned-players.txt
    crash-reports
    logs
    ops.txt
    server.properties
    white-list.txt

You can just copy your world into the worlds directory:

    mkdir /opt/mscs/worlds/alpha
    cp -R * /opt/mscs/worlds/alpha

After you've copied the world files, you will want to [create a world entry
into MSCS](#creating-a-new-world) using the name of the world and the port
that you wish the world to use:

    mscs create alpha 25565


#### Renaming world folder
If you would like to rename the `alpha` folder
(the one that is the parent folder of the actual world) to a different name,
follow the steps below.

IMPORTANT: make sure the world that you are importing is not currently
running.

In this example we want to rename the `alpha` folder to `vanillaMC`:

    mkdir /opt/mscs/worlds/vanillaMC
    cp -R * /opt/mscs/worlds/vanillaMC
    mv /opt/mscs/worlds/vanillaMC/alpha /opt/mscs/worlds/vanillaMC/vanillaMC

After you've set up the file structure, [you can now create a world entry
into MSCS](#creating-a-new-world) using the name of the world and the port
that you wish the world to use:

    mscs create vanillaMC 25565

### Adjusting global server properties
Default values in the script can be overridden by adding certain properties to one
of the `mscs.defaults` files. The `mscs.defaults` files can be found found in one
of three places depending on how the script is being used. When using the `mscs`
script, the `mscs.defaults` file can be found at `/opt/mscs/mscs.defaults`. When
using the `msctl` script in [multi-user mode](https://github.com/MinecraftServerControl/mscs/wiki/Configuring-MSCS-for-multiple-users), the `mscs.defaults` file can be found at either `$HOME/mscs.defaults` or `$HOME/.config/mscs/mscs.defaults`.

For more information on the various properties, see the [wiki page](https://github.com/MinecraftServerControl/mscs/wiki/Global-Server-Settings).

#### Default global server properties
Below are the default global server properties. You can add one, none, or all
of the properties below to one of the `mscs.defaults` files and adjust it to
your liking.

    mscs-location=/opt/mscs
    mscs-worlds-location=/opt/mscs/worlds
    mscs-versions-url=https://launchermeta.mojang.com/mc/game/version_manifest.json

    mscs-maps-location=/opt/mscs/maps
    mscs-maps-url=http://minecraft.server.com/maps

### Adjusting world properties
Each world server can override the default values in a similar manner by
adding certain properties to the world's `mscs.properties` file. The
`mscs.properties` file can be found in every world folder (for instance, if
you had a world called `myWorld`, the path would be
`/opt/mscs/worlds/myWorld/mscs.properties`). This file allows you to adjust
many different properties for each world you have.  By default, the file only
has one line in it: `mscs-enabled=true`.

The following properties are available:
* mscs-enabled - Enable the world server (true or false).
* mscs-version-type - Assign the version type (release or snapshot).
* mscs-client-version - Assign the version of the client software.
* mscs-client-jar - Assign the .jar file for the client software.
* mscs-client-url - Assign the download URL for the client software.
* mscs-client-location - Assign the location of the client .jar file.
* mscs-server-version - Assign the version of the server software.
* mscs-server-jar - Assign the .jar file for the server software.
* mscs-server-url - Assign the download URL for the server software.
* mscs-server-args - Assign the arguments to the server.
* mscs-initial-memory - Assign the initial amount of memory for the server.
* mscs-maximum-memory - Assign the maximum amount of memory for the server.
* mscs-server-location - Assign the location of the server .jar file.
* mscs-server-command - Assign the command to run for the server.

The following variables may be used in some of the values of the above keys:
* $JAVA - The Java virtual machine.
* $CURRENT_VERSION - The current Mojang Minecraft release version.
* $CLIENT_VERSION - The version of the client software.
* $SERVER_VERSION - The version of the server software.
* $SERVER_JAR - The .jar file to run for the server.
* $SERVER_ARGS - The arguments to the server.
* $INITIAL_MEMORY - The initial amount of memory for the server.
* $MAXIMUM_MEMORY - The maximum amount of memory for the server.
* $SERVER_LOCATION - The location of the server .jar file.

#### Default world properties
Below are the default properties for the world. You can add one, none, or all
of the properties below to the `mscs.properties` file and adjust it to your
liking.

    mscs-enabled=true
    mscs-version-type=release
    mscs-client-version=$CURRENT_VERSION
    mscs-client-jar=$CLIENT_VERSION.jar

#### Enabling Forge, BungeeCord, and other server software
Please visit the [wiki](https://github.com/MinecraftServerControl/mscs/wiki/Server-Customization-Examples)
for additional information.

## Scheduling backups and other tasks
All MSCS tasks can be automated using [**cron**](https://en.wikipedia.org/wiki/Cron),
a scheduler software that can run programs on a set interval of time. Whether
it be backups, restarts, mapping, or any other `mscs` command, it can be
scheduled using `cron`.

### Scheduling backups
Below is an example of one way you could setup backups via `cron` to backup a
world every 2 hours:

Edit the crontab file for the `minecraft` user using `sudo`:

    sudo crontab -e -u minecraft

Page down until you get to an empty line. Then paste the following:

    # Define PATH
    PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

    # Run mscs backups
    0 */2 * * *  mscs backup myWorld

* We define the PATH because `cron` doesn't do it for us.

* `0 */2 * * *` is the time interval to backup. This particular expression
  means backup every 2 hours. You can change this to 3, 4, 5, etc to backup
  every X amount of hours. You can also backup according to days, minutes,
  seconds, the time of the day, and more. See [the wiki page](https://github.com/MinecraftServerControl/mscs/wiki/Backup-and-Restore)
  for more information.

* `myWorld` is the name of the world you wish to backup. Omitting this will
  backup all worlds.

* The backups will be saved in `/opt/mscs/backups`.

### Removing backups after X days
You can specify how long to keep backups by changing the
`mscs-backup-duration` property in the `mscs.defaults` file (see
[adjusting global server properties](#adjusting-global-server-properties)
).

### Scheduling restarts
You can schedule restarts for the server following the same method as outlined
in [scheduling backups](#scheduling-backups). Simply change the scheduled
command to:

    mscs restart <world>

Where `<world>` is the name of the world you wish to restart (omit for all
worlds).

### Scheduling mapping
You can also schedule mapping using the same method outlined in
[scheduling backups](#scheduling-backups). Simply replace the command with:

    mscs map <world>

Where `<world>` is the name of the world you wish to map (omit for all
worlds).

## Installing Overviewer (the mapping software)

Overviewer is the mapping software that MSCS uses. 
It has pretty straightforward documentation to download and install the software:

* [Debian/Ubuntu](http://overviewer.org/debian/info)
* [RHEL/CentOS/Fedora](http://overviewer.org/rpms/info)

> __NOTE:__ Once you follow the install page, come back here for further instructions.
> Don't read the "Running the Overviewer" section, as it will differ in MSCS.

You can also [download](http://overviewer.org/downloads) premade binaries for
supported systems, or build your own binary from source if needed.

### Configuring Overviewer

Overviewer currently requires a free Google API key. You can obtain one 
[here](https://developers.google.com/maps/documentation/javascript/get-api-key). 
On the webpage, Select the blue "Get a Key" button. Then, follow the prompts.
You can create a new project or use the already-made "My Project" to obtain
the API key--it doesn't matter. Copy this key, you'll need it. Then,
download the script found [here](https://github.com/Zeromusta/docker-spigot-overviewer/blob/master/rootfs/usr/local/bin/ov_keyfix)
and paste your API key into the `AddString="&key="` line, so that it looks like `AddString="&key=00000000000000000"` where the
zeroes are your API key. Once you've ran this file, Overviewer should work. You also want to run this whenever Overviewer is updated.

In the `mscs.defaults` file (one will be created if you haven't created one manually), 
you'll find various Overviewer mapping settings which you change to your liking.
We've listed the map-related settings below:
(see [adjusting global server properties](#adjusting-global-server-properties) if you're confused where the file is)
    
* `mscs-overviewer-bin`: This is the location for the Overviewer binary.                                                                                                                       If you manually installed Overviewer to another location, you can enter the location here.
* `mscs-overviewer-url`: A clickable link for users in chat to view the overviewer website.
* `mscs-maps-location`: The location to store the generated maps. Change this value
   to your web-server folder, e.g. `var/www/` (or symlink your web-server folder to this value).
* `mscs-maps-url`: The link to be displayed in chat to view the maps when mapping is complete. 

After you've changed the settings, run:

    mscs map <world>

Where `<world>` is the name of the world you would like to get mapped.
Omit the world name to map all worlds.

If you get a `Permission denied` error, please see the [Troubleshooting section](#troubleshooting).

Please note that in order for the map to update new changes in the world,
you need to run Overviewer periodically.
Please see [scheduling mapping](#scheduling-mapping) for more information.

### Changing the Default Rendering Settings

By default, we've set up MSCS to render the overworld, the nether, the end, and cave systems 
with Overviewer's "normal" render settings. However, Overviewer has many different render 
modes which you can apply to as many or as few dimensions of your world(s) as you like.

All you have to do is change the config file, which is located at 
`/opt/mscs/worlds/myWorld/overviewer_settings.py`, where `myWorld` is the name of your world.

To view more information on render modes and how to customize the config file, 
[click here](http://docs.overviewer.org/en/latest/config/#examples).

### Troubleshooting

#### Permission denied when attempting to run `mscs create ...`
