BigBlueButton 0.81基于Ubuntu 12.04LTS 64位安装
Installing BigBlueButton 0.81
These instructions assume you do not havea previous version of BigBlueButton installed.
If you are upgrading from BigBlueButton0.80 to 0.81, starthere.
1.Update your server
The following steps will install 0.81.
You first need to give your server accessto the BigBlueButton package repository.
In a terminal window, copy and paste thefollowing commands.
# Add the BigBlueButton key
wget http://ubuntu.bigbluebutton.org/bigbluebutton.asc-O- | sudo apt-key add -
# Add the BigBlueButton repository URLand ensure the multiverse is enabled
echo "deb http://ubuntu.bigbluebutton.org/lucid_dev_081/bigbluebutton-lucid main"| sudo tee /etc/apt/sources.list.d/bigbluebutton.list
Next, ensure that you havelucid multiversein yoursources.list. Do the following.
$ grep "lucid multiverse"/etc/apt/sources.list
If you have thelucid multiversein yoursources.list, you should see
deb http://us.archive.ubuntu.com/ubuntu/ lucidmultiverse
If you don't see the deb line forlucid multiverse, execute the following line to add this repository tosources.list.
echo "deb http://us.archive.ubuntu.com/ubuntu/ lucid multiverse"| sudo tee -a /etc/apt/sources.list
Before proceeding further, do adist-upgrade to ensure all the current packages on your server are up-to-date.
sudo apt-get update
sudo apt-get dist-upgrade
If you've not updated in a while, apt-getmay recommend you reboot your server afterdist-upgradefinishes. Do the reboot before proceeding to the nextstep.
2.Install LibreOffice
BigBlueButton uses LibreOffice to convertuploaded MS office documents to PDF. LibreOffice does a far better job ofconverting documents than the default OpenOffice packages in Ubuntu 10.04.
First, we'll install a stub package foropenoffice. This will serve as a placeholder for BigBlueButton's dependency onOpenOffice..
wget http://bigbluebutton.googlecode.com/files/openoffice.org_1.0.4_all.deb
sudo dpkg -i openoffice.org_1.0.4_all.deb
If you get an error in the above, check ifyou have openoffice.org-core installed. If so, remove all the existingopenoffice.org pacakges and try to install the above stub package again.
Next, we'll install LibreOffice
sudo apt-get install python-software-properties
sudo apt-add-repository ppa:libreoffice/libreoffice-4-0
sudo apt-get update
sudo apt-get install libreoffice-common
sudo apt-get install libreoffice
3.安装ruby组件之前，需要把一些兼容的依赖包加以安装，这样才能成功安装ruby.
l安装以下依赖包
l安装gcc编译环境：
a)$sudo apt-get installbuild-essential
b)为了成功编译gSOAP，您需要安装GTK+的开发文件和GLib库(libraries)。
$sudoapt-get install libgtk2.0-dev libglib2.0-dev
c)安装Checkinstall以便管理您系统中直接由源代码编译安装的软件。
$sudoapt-get install checkinstall
llibpq-dev
sudo add-apt-repository ppa:pitti/postgresql
sudo apt-get update
sudo apt-get install postgresql libpq-dev
sudo apt-get install libpg-de
apt-get install libxslt-dev libxml2-dev libpam-dev libedit-dev

4.Install Ruby
The record and playbackinfrastructure uses Ruby for the processing of recorded sessions.
Check if you have a previousversion of ruby install.
dpkg -l | grep ruby
If you already have rubyinstalled, check it's version
~$ ruby -v
ruby 1.9.2p290(2011-07-09 revision 32553)
If the version of ruby does notmatch the above, uninstallitbefore continuing.
5.Install ffmpeg
BigBlueButton uses ffmpeg toprocess video files for playback. To install ffmpeg, create a file calledinstall-ffmpeg.shandcopy and paste in the following script.
sudo apt-get install build-essential git-core checkinstall yasm texi2html libvorbis-dev libx11-dev libxfixes-dev zlib1g-dev pkg-config
LIBVPX_VERSION=1.2.0
FFMPEG_VERSION=2.0.1
if[!-d "/usr/local/src/libvpx-${LIBVPX_VERSION}"];then
cd /usr/local/src
sudo git clone http://git.chromium.org/webm/libvpx.git "libvpx-${LIBVPX_VERSION}"
cd "libvpx-${LIBVPX_VERSION}"
sudo git checkout "v${LIBVPX_VERSION}"
sudo ./configure
sudo make
sudo checkinstall --pkgname=libvpx --pkgversion="${LIBVPX_VERSION}"--backup=no--deldoc=yes --default
fi
if[!-d "/usr/local/src/ffmpeg-${FFMPEG_VERSION}"];then
cd /usr/local/src
sudo wget "http://ffmpeg.org/releases/ffmpeg-${FFMPEG_VERSION}.tar.bz2"
sudo tar -xjf "ffmpeg-${FFMPEG_VERSION}.tar.bz2"
cd "ffmpeg-${FFMPEG_VERSION}"
sudo ./configure --enable-version3 --enable-postproc --enable-libvorbis --enable-libvpx
sudo make
sudo checkinstall --pkgname=ffmpeg --pkgversion="5:${FFMPEG_VERSION}"--backup=no--deldoc=yes --default
fi
Next, run the commands
chmod +x install-ffmpeg.sh
./install-ffmpeg.sh
After the script finishes, checkthat ffmepg is installed by typing the commandffmpeg-version. You should see the following
$ ffmpeg -version
ffmpeg version 2.0.1
built on Sep1201302:02:28with gcc 4.4.3(Ubuntu4.4.3-4ubuntu5.1)
configuration:--enable-version3 --enable-postproc --enable-libvorbis --enable-libvpx

libswresample 0.17.102/0.17.102
6.Install BigBlueButton
We're now ready to install BigblueButton. Type
sudo apt-get install bigbluebutton
This single command is where all the magic happens. This commandinstallsallof BigBlueButton components with theirdependencies. The packaging will do all the work for you to install andconfigure your BigBlueButton server.
If you are behind a HTTP Proxy, you will get an error from thepackage bbb-record-core. You can resolve this bymanually installing the gems.
If you get an error message
......Error:FreeSWITCH didn't start
you can ignore it as we'll do a clean restart of all thecomponents in step 7.
7. Install API Demos
To interactively test your BigBlueButton server, you can install aset of API demos.
sudo apt-get install bbb-demo
You'll need the bbb-demo package installed if you want to join theDemo Meeting from your BigBlueButton server's welcome page. This is the samewelcome page you see atdev081 demoserver.
Later on, if you wish to remove the API demos, you can enter thecommand
sudo apt-get purge bbb-demo
8. Doa Clean Restart
To ensure BigBlueButton has started cleanly, enter the followingcommands:
sudo bbb-conf --clean
sudo bbb-conf --check
The--cleanoptionwill clear out all the log files for BigBlueButton. The--checkoptionwill grep through the log files looking for errors.
The output fromsudo bbb-conf --checkwilldisplay your current settings and, after the text, "Potential problems described below", print any potentialconfiguration or startup problems it has detected.
