In this tutorial/howto we install the Mumble-Ruby-Pluginbot into a users home directory. No system services are used.
How much time will you need?¶
This tutorial works well using copy and paste if you want one bot only. If you want more bots, read the note boxes and warning boxes :)
After 10 to 20 minutes it should be finished, depending on your servers internet connection.
How will it look like?¶
This will be the directory structure when this howto is completed:
/home/botmaster/ ├── mpd1 │ ├── playlists │ ├── mpd1.log │ ├── mpd.conf │ ├── mpd.fifo │ ├── pid │ ├── state │ ├── sticker.sql │ └── tag_cache ├── (optional) more mpd directories ... mpd2, mpd3, etc. ├── logs ├── music │ └── downloadedfromyt │ └── downloadedfromsc │ └── [...] ├── src │ └── certs │ └── nameofyourbot_cert │ └── [...] │ └── mumble-ruby │ └── mumble-ruby-pluginbot │ │ └── scripts │ │ └── mumblerubypluginbot.service │ │ └── overwrite_conf.rb │ │ └── manage.sh │ │ └── updater.sh │ │ └── [...] │ └── bot1_conf.yml │ └── (optional) more bot<number>_conf.yml │ └── [...] ├── temp │ └── youtubeplugin │ └── bandcampplugin │ └── [...] [...]
On Arch Linux only: Install and set up system package dependencies¶
Install the following dependencies as root or via sudo:
pacman -S libyaml opus zlib openssl git mpd mpc tmux automake \ autoconf libogg psmisc util-linux libtool curl base-devel wget aria2
On CentOS 7 only: Install and setup package dependencies¶
Install the following dependencies as root:
yum install libyaml opus-tools wget aria2 libyaml-devel git opus-devel \ zlib zlib-devel openssl-devel mpd libmpc tmux automake autoconf libtool \ libogg-devel gmp-devel dialog unzip bzip2
On Debian/Ubuntu based Distributions only: Install and set up system package dependencies¶
Install the following dependencies as root or via sudo (please not that this is one command, copy and paste all four lines):
apt-get install curl libyaml-dev git libopus-dev \ build-essential zlib1g zlib1g-dev libssl-dev mpd mpc tmux \ automake autoconf libtool libogg-dev psmisc util-linux libgmp3-dev \ dialog unzip ca-certificates aria2
The message about
no database /var/lib/mpd/tag_cache can be ignored. The database will be created as soon as you start the MPD server.
As we do not need the system wide MPD it can be disabled. To do this open the file
/etc/default/mpd as root or via sudo and change
false. At the next system start it will not be started any more.
On newer distributions instead of editing the file you need to disable the MPD service by running the following command as root or with sudo:
systemctl disable mpd systemctl stop mpd
Create a user which should contain all the relevant bot structures¶
It is crucial that you use the same username as in this tutorial. Otherwise you need to manually adapt most scripts and configuration files to another username.
As root or via sudo:
All relevant scripts will run within this user context.
Now it is the time to log in as your new user with:
su - botmaster
All the following steps are done as the user botmaster.
Create all needed directories and subdirectories for MPD and the bot(s)¶
Create a directory for the source code and scripts:
Create a direcotry for log files:
Create a directory for the certificates:
Create a directory for the music:
Create a directory for the temp files:
Create the directories for bot 1:
mkdir -p ~/mpd1/playlists
Note that you can use more than one bots with this tutorial. Just create a new directory structure for every additional bot, for example with:
mkdir -p ~/mpd2/playlists
and so on.
Install and set up ruby and all needed libraries¶
We are using RVM (Ruby Version Manager) to install a local version of Ruby instead of using a system wide installed Ruby which may be too old.
First get and add the GPG key of RVM:
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
We need at least Ruby 1.9.x, here we use the latest stable version:
curl -L https://get.rvm.io | bash -s stable
Now we need to tell our current shell to use rvm:
Disable autolibs so that rvm doesn’t ask for root - we already installed all the dependencies earlier:
rvm autolibs disable
The next command should print nothing, if it does print something, login as root and install those:
Now we install the latest stable version of Ruby:
rvm install ruby --latest
Set up a Ruby environment¶
Now setup the environment for Ruby:
rvm --create use @bots
Get and build mumble-ruby and ruby-mpd and other dependencies¶
Now we download the source code of Mumble-Ruby and build it:
cd src git clone https://github.com/dafoxia/mumble-ruby.git mumble-ruby cd mumble-ruby rvm use @bots gem build mumble-ruby.gemspec rvm @bots do gem install mumble-ruby-*.gem
Install ruby-mpd so that the bot can control MPD:
rvm @bots do gem install ruby-mpd rvm @bots do gem install crack
Download and set up celt-ruby and libcelt¶
For compatibility reasons the bot uses slightly modified versions of CELT which need to be built with the following steps:
cd ~/src git clone https://github.com/dafoxia/celt-ruby.git cd celt-ruby rvm use @bots gem build celt-ruby.gemspec rvm @bots do gem install celt-ruby cd ~/src git clone https://github.com/mumble-voip/celt-0.7.0.git cd celt-0.7.0 ./autogen.sh ./configure --prefix=/home/botmaster/src/celt make make install
Download and set up opus-ruby¶
Do the following commands:
cd ~/src git clone https://github.com/dafoxia/opus-ruby.git cd opus-ruby rvm use @bots gem build opus-ruby.gemspec rvm @bots do gem install opus-ruby
Download and set up mumble-ruby-pluginbot¶
Do the following commands:
cd ~/src git clone https://github.com/MusicGenerator/mumble-ruby-pluginbot.git cd mumble-ruby-pluginbot
We need a configuration file for the manage script:
cp templates/manage.conf ~/src/manage.conf
Now we create a copy of the config that we will use:
cp templates/override_config.yml ~/src/bot1_conf.yml
This approach has the advantage that this config file contains only the variables you want to change. All the other variables not set in your bot1_conf.yml are used from the ~/src/mumble-ruby-pluginbot/config/config.yml file and all plugins/*.yml files. See here for details.
You should now edit the bots configuration file named “bot1_conf.yml” with your favorite editor:
… and adapt at least the following settings to your needs:
- mumble -> host
- mumble -> port
- mumble -> username
- mumble -> password
- Note: This password is optional only and not needed if you want to register the bot as an admin on your server.
- mumble -> channel
- Note: This channel name is the one your bots tries to enter when getting a .gotobed
- mumble -> bitrate
- Note: If you set a higher bandwidth than your server can handle the bot automatically reduces its bandwidth to fit the servers needs.
The rest of the configuration file should be fine.
For every additional bot you need to copy the original config file and edit it, for example for bot 2 do:
cd ~/src/mumble-ruby-pluginbot cp templates/override_config.yml ~/src/bot2_conf.yml
Now edit ~/src/bot2_conf.yml and change at least the following variables:
- main -> logfile to “/home/botmaster/logs/bot2.log”, and so forth
- main -> fifo to “/home/botmaster/mpd2/mpd.fifo”, and so forth
- mumble -> name to “anything different then for bot1”, and so forth
- plugin -> mpd -> port to 7702, and so forth
Set up MPD (Music Player Daemon)¶
Copy the configuration file for your local MPD:
cp ~/src/mumble-ruby-pluginbot/templates/mpd.conf ~/mpd1/mpd.conf
For every additional bot you must increase the number of ~/mpd1/… by one. For a second bot use:
cp ~/src/mumble-ruby-pluginbot/templates/mpd.conf ~/mpd2/mpd.conf
Then open the downloaded
mpd.conf file and substitude every occurence of
mpd2. Also increase the port from 7701 to 7702, 7703, etc.
For experts only: Explanations about the configuration file and additional settings you may want to have…
You can see the configuration file at here..
Instead of the default sample rate of 44100 this config uses 48000 which is the sample rate Mumble clients use. And we need a mono signal.
The mixer type is set to software so that the volume in MPD can be changed without the need of a real soundcard.
You can enable volume normalization by adding the following line to the mpd config file:
Set up the script to start your bot(s) and MPD instance(s)¶
Change into the mumble-ruby-pluginbot directory:
The Bash script named
manage.sh in the scripts directory is used to start all your bots and your MPD instance(s).
Make it executable:
chmod u+x ~/src/mumble-ruby-pluginbot/scripts/manage.sh
Also make the update script executable:
chmod u+x ~/src/mumble-ruby-pluginbot/scripts/updater.sh
If you created more than one bot in this tutorial open the file ~/src/manage.conf and add every additional bot (its number) to the value of BOTS_ENABLED. For example if you created two bots, set the value to “1 2”. When you created three bots set it to “1 2 3”.
Without modification the scripts starts only bot 1, for every additional bot modify ~/src/manage.conf.
Install a custom version of youtube-dl¶
You don’t want to rely on the distributions version of an old youtube-dl so you must setup an own.
Only on Arch Linux: Install dependencies for youtube-dl¶
As root or with sudo install:
pacman -S imagemagick ffmpeg python
Only on CentOS 7: Install dependencies for youtube-dl¶
As root install:
yum install ImageMagick python ffmpeg
Only on Debian/Ubuntu based distributions: Install the dependencies (if ffmpeg is available for your distribution)¶
First install as root or via sudo the following system packages:
apt-get install imagemagick ffmpeg python
Only on Debian/Ubuntu based distributions (OPTIONAL): Install the dependencies (if ffmpeg IS NOT available for your distribution)¶
On some distributions the package ffmpeg was replaced by libav-tools; install this if ffmpeg is not available.
Install as root or via sudo the following system packages:
apt-get install imagemagick libav-tools python
Also create the symlink so that the plugin can find it:
ln -s /usr/bin/avconv /usr/bin/ffmpeg
Login as botmaster¶
If not already logged in as botmaster, then do:
su - botmaster
Install the youtube-dl script¶
The youtube plugin needs youtube-dl; download it and make it executable:
curl -L https://yt-dl.org/downloads/latest/youtube-dl -o ~/src/youtube-dl chmod u+x ~/src/youtube-dl
Almost done, start your bot(s) for the first time¶
You almost finished; now you can run your bot(s):
When the bot(s) appear on your server, register it/them and start working with it/them. Try
.help as the first command.
If the bot does not connect refer to Known problems.
Set up bot to start automatically on system startup¶
Start everything automatically – if your system is NOT systemd¶
Add the following lines to
/etc/rc.local before the
exit... line to start your bot(s) when your system starts:
su - botmaster -c "/home/botmaster/src/mumble-ruby-pluginbot/scripts/manage.sh start" &
The bot will start automatically on the next system start.
Start everything automatically – if your system is systemd¶
Run the following command as root:
cp /home/botmaster/src/mumble-ruby-pluginbot/templates/mumblerubypluginbot.service /etc/systemd/system/ systemctl enable mumblerubypluginbot
The bot will start automatically on the next reboot.
Thats it, you are done :)
Controlling the bot(s) from your shell¶
To restart your bot(s) run:
To stop your bot(s) run:
To watch log files in real time run:
To get the current status of your bot(s) run:
