Overview

This module will install McMyAdmin, a Minecraft control panel. Multiple instances can be installed.

Details

32-bit versions of McMyAdmin use Mono. If you install McMyAdmin 32-bit, your distro package will be installed. The 64-bit version of McMyAdmin includes configuration files, which will be placed in /usr/local/etc/

Minecraft itself requires Java, which can optionally be installed with this module by using the manage_java parameter.

This module installs an init script for each instance, which will launch McMyAdmin from within a screen session. This module can optionally install screen by using the manage_screen parameter.

If all goes well, you should be able to login to the McMyAdmin web interface after using this module.

Note: this doesn't configure McMyAdmin or initiate the Minecraft server installation - that is handled via the McMyAdmin web interface. The only thing configured is the listening address and port.

NEW: This module now supports multiple instances of McMyAdmin on the same server. You must explicitly provide a port number for each instance, however. Details below.

Usage Examples

Multiple instances

NOTE: It is up to you to specify non-conflicting webserver_port parameters for each instance. Additionally, any Minecraft server configured via the McMyAdmin web interface must choose unique ports.

include mcmyadmin

# This will create an instance on port 8080
# with a user/group/home named 'jbeard' and
# an init script called mcmyadmin.number1
mcmyadmin::instance { 'number1':
  webserver_port    => '8080'
  user              => 'jbeard',
  password          => '$ecret',
}

# This will create an instance on port 9090
# with a username, group, and home named 'somegame'
# and an init script called mcmyadmin.somegame
mcmyadmin::instance { 'somegame':
  webserver_port    => '9090'
}

Single Instance

To install a single instance (same behavior as previous versions of this module):

include mcmyadmin

# This will create an init script called 'mcmyadmin'
# The 'default' instance is for single instances
mcmyadmin::instance { 'default':
  webserver_port    => '8080',
  user              => 'jdoe',
  group             => 'jdoe',
  password          => 'hunter2',
}

mcmyadmin Class Parameters

install_arch

This determines which version of the McMyAdmin installer will be downloaded and installed. Default: '64' on x86_64/Linux systems; '32' on all others.

manage_java

Boolean: true/false

Whether to install Java or not. Required for Minecraft.

manage_screen

Boolean: true/false

Whether to install screen or not. The init script executes McMyAdmin within a screen session.

manage_mono

Boolean: true/false

Whether to install mono distro package. This is only relevant when install_arch isn't '64', which only applies to Linux. Note: EPEL is required on RedHat-like systems.

mono_pkg

Mono package to be installed. Default: mono-complete on Debian/Ubuntu. mono-core on RedHat/CentOS (EPEL is required). lang/mono on FreeBSD.

screen_pkg

Screen package to be installed. Default: RedHat/Debian: screen; FreeBSD: sysutils/screen

manage_curl

Boolean: true/false

Whether to manage the curl package or not. Defaults to false on Linux and true on FreeBSD. You probably don't need to change this. If you're running FreeBSD and are already managing the curl package with Puppet, set this parameter to false

The staging module that this module uses requires curl or wget to download the remote package, neither of which are installed by default on FreeBSD.

curl_pkg

curl package to be installed. curl on Linux and ftp/curl on FreeBSD. This parameter doesn't matter if manage_curl isn't set to true

staging_dir

Full path to the staging directory (see above). This should be persistent across reboots.

This is /opt/staging on Linux (as set by the staging module) and /var/tmp/staging on FreeBSD (as set by the mcmyadmin module)

You probably don't need to change this parameter.

Defined type: mcmyadmin::instance

The title/name you pass to this defined type will, unless other specified using the parameters below, will become the username, group name, password, home directory name, and an init script will be created called mcmyadmin.${name}

The name default is special, however, to preserve some level of backwards-compatability with single instances. If a default instance is declared, the init script will simply be called mcmyadmin

NOTE: Unfortunately, due to the way the staging module works, each instance will download its own copy of McMyAdmin.

webserver_port

Required. Port for the McMyAdmin web service to listen on.

webserver_addr

Address for the McMyAdmin web service to listen on. Default: + (all interfaces)

password

The password to use for the McMyAdmin web admin user. Default: ${name}

The user (unix) account on the system will not have a password set.

user

The user to operate as. A home directory will be created. Default: ${name}

group

Group to create. The user will be a member of this. Default: ${name}

user_shell

The shell for the user. Default: /usr/sbin/nologin

homedir

Path to the home directory. Default: /home/${name}

install_dir

Where McMyAdmin will be installed. Default: ${homedir}/McMyAdmin

mcma_run_args

Command-line arguments to pass to the MCMA binary when running.

Default: empty

mcma_install_args

Command-line arguments to pass to the MCMA binary when installing.

Default: empty

Backwards Compatibility

Previous versions of this module didn't support multiple instances of McMyAdmin on a single server. To replicate a single instance that you already have in place from a previous application of this module, see the Single Instance example above. For example, if you had the following previously:

include mcmyadmin

You would do something like:

include mcmyadmin

mcmyadmin::instance { 'default':
  port  => '8080',
}

The default instance is special in that it will keep a simple init script called mcmyadmin, rather than an instance-specific one.

Limitations

This has been tested on CentOS, Ubuntu, and FreeBSD 9.2 with pkgng.

The unzip tool is required, which isn't installed by default on some systems (Debian) and this module doesn't attempt to manage it.

FreeBSD Notes

This was tested with pkgng

You can use a pkgng provider by performing:

puppet module install zleslie-pkgng

and doing something like this on your system:

Package {
  provider => 'pkgng',
}

This will set pkgng to be the default provider for package installation.
