How To Install And Configure Apache Openmeetings 2.2.0 on CentOS 6.5

 

Openmeetings is an open-source video-conferencing, instant messaging, white board, screen sharing, collaborative document editing project from Apache foundation. In order to install it on CentOS, we need several prerequisites. Some of them are part of the CentOS repository and some of them need to be downloaded and compiled. First, let’s install the packages from the CentOS repo.

1.yum install wget telnet gcc-c++ zlib-devel libjpeg-devel freetype-devel
giflib-devel ghostscript ImageMagick unzip sox libreoffice mysql mysql-server

The following will be installed:
  • wget for retrieving files using HTTP, HTTPS and FTP.
  • telnet client for checking and troubleshooting port connectivity
  • gcc-c++ a GNU C++ compiler
  • zlib-devel a compression library
  • libjpeg-devel a library for reading and writing JPEG files
  • freetype-devel is a library used to produce vector and bitmap fonts
  • giflib-devel a library  to load and save GIF images
  • ghostscript is a interpreter for PostScript language and PDF
  • ImageMagick is a software suite to create, edit, compose and convert bitmap images
  • unzip is a program to compress (zip) and extract (unzip) files
  • sox is a general purpose sound file conversion tool
  • libreoffice is a suite of Office programs (calc, spreadsheet, word) a fork from OpenOffice
  • mysql is an open-source SQL database.
    We have to configure mysql to start on boot and do some initial configuration.
    1   
    2
    3
    chkconfig mysqld on
    service mysqld start
    mysql_secure_installation
 Now, let’s create the database that will be used for openmeetings. Change ‘your password’ with a password that you want to use for the mySQL user openmeetings. This user will have full rights to the database.

mysql –u root –p
CREATE DATABASE openmeetings DEFAULT CHARACTER SET 'utf8';
GRANT ALL PRIVILEGES ON openmeetings.* TO 'openmeetings'@'localhost' IDENTIFIED BY 'your_password' WITH GRANT OPTION;
quit


The next step is to download the prerequisites that are not part of the CentOS repo. We will use /tmp directory as a staging area. First, we’ll install swftools, a collection of utilities for working with Adobe Flash files.

cd /tmp
wget http://www.swftools.org/swftools-0.9.2.tar.gz
tar xvf swftools-0.9.2.tar.gz
cd swftools-0.9.2
./configure --libdir=/usr/lib --bindir=/usr/bin
make
vi swfs/Makefile

There is a bug in the Makefile that won’t allow us to properly compile the utilities. Just remove “-o -L” in two rm lines.

Save and quit with “:wq!” and then install it.

2
make install
cd ..

We need to install jodconverter, which is an utility that automates conversions between Open Office and Libre Office documents, then install lame, which is a MP3 encoder and finally install ffmpeg which is a toolset to record, convert and stream audio and video.



wget http://jodconverter.googlecode.com/files/jodconverter-core-3.0-beta-4-dist.zip
 
unzip jodconverter-core-3.0-beta-4-dist.zip
wget http://downloads.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz?r=http%3A%2F
%2Fsourceforge.net%2Fprojects%2Flame%2Ffiles%2Flame%2F3.99%2F&ts=1392491323&use_mirror=hivelocity
mv lame-3.9* lame-3.99.5.tar.gz
tar xvf lame-3.99.5.tar.gz
cd lame-3.99.5
./configure --libdir=/usr/lib --bindir=/usr/bin
make
make install
cd ..
wget http://ffmpeg.org/releases/ffmpeg-1.1.1.tar.gz
tar xvf ffmpeg-1.1.1.tar.gz
cd ffmpeg-1.1.1
./configure --libdir=/usr/lib --bindir=/usr/bin --enable-libmp3lame --disable-yasm
make
make install
cd ..


openmeetings heavily relies on Java and when we installed Libre Office we installed OpenJDK. But, we need Oracle Java JRE. Let’s install it. First, check the installed version.




java -version

Install and compile.

cd /tmp
wget --no-cookies --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com" "http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-x64.tar.gz"
tar xvf jdk-7u51-linux-x64.tar.gz
mv jdk1.7.0_51 /opt
vi /etc/profile.d/java.sh


Enter these lines and save the file.


export JAVA_HOME=/opt/jdk1.7.0_51
export PATH=$PATH:$JAVA_HOME/bin
export JRE_HOME=/opt/jdk1.7.0_51/jre
 
Check what we have.


ls -la /etc/alternatives/java*
alternatives --install /usr/bin/java java /opt/jdk1.7.0_51/bin/java 1
alternatives --config java

Select “2″ and hit Enter to select the Oracle JRE. Then do:


java -version

You should see the correct version now.

java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode)

Finally, let’s install openmeetings.


mkdir /openmeetings
cd /openmeetings
wget http://mirror.sdunix.com/apache/openmeetings/2.2.0/bin/apache-openmeetings-2.2.0.tar.gz
tar xvf apache-openmeetings-2.2.0.tar.gz
rm apache-openmeetings-2.2.0.tar.gz
Get the Java mySQL connector.


cd /tmp
wget http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.0.8.tar.gz
tar xvf mysql-connector-java-5.0.8.tar.gz
cp mysql-connector-java-5.0.8/mysql-connector-java-5.0.8-bin.jar /openmeetings/webapps/openmeetings/WEB-INF/lib
cd /openmeetings/webapps/openmeetings/WEB-INF/classes/META-INF
cp mysql_persistence.xml persistence.xml
Edit persistence.xml file and change the username and password with the username and password that you used when you created the mySQL database.
Go back to the install folder.


cd /openmeetings/webapps/openmeetings
cp -R /tmp/jodconverter-core-3.0-beta-4 .
cd /openmeetings
Finally, start the streaming server.



sh red5.sh
If everything goes well, you should see a bunch of output from the servlets.
Wait for 3-4 minutes until you see that the output stabilizes, make sure that port 5080 is open and then go to:
You should see this welcome page.




Click Continue with STEP1 and you should see this screen.



Enter the mySQL credentials, type the admin e-mail, choose the time zone and scroll all the way down and click Install. The rest of the fields can be ignored and you can configure them later. If you switch to the terminal, you’ll see a lot of activity.

Once completed, you’ll be greeted that the installation is complete. Click the Enter the Application link.


Log with the admin credentials.


 This is the main screen.





Go to Administration | Configuration and make sure that you have the following values properly configured.
  • SWFTools Path = /usr/bin
  • ImageMagick Path = /usr/bin
  • FFMPEG Path = /usr/bin
  • SoX Path = /usr/bin
When you start the conference, make sure you test your audio/video equipment.

Finally, if you want to start the servlet automatically, create the following file.


vi /etc/init.d/red5

#
#!/bin/sh -e
#
# chkconfig: 2345 20 80
# description: Startup script for Red5/openmeetings
 
export RED5_HOME=/openmeetings/
start_red5="$RED5_HOME/red5.sh"
stop_red5="$RED5_HOME/red5-shutdown.sh"
  
start() {
        echo -n "Starting Red5: "
        ${start_red5} &
        echo "done."
}
stop() {
        echo -n "Shutting down Red5: "
        ${stop_red5}
        echo "done."
}
  
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  restart)
        stop
        sleep 10
        start
        ;;
  *)
        echo "Usage: $0 {start|stop|restart}"
esac
  
exit 0
 
And make it run at boot.


chmod +x /etc/init.d/red5
service red5 stop
chkconfig red5 on
service red5 start


That's IT. Enjoy UR Self with Apache OpenMeeting!!!
