Installation

We;ll be using Centos 6.5 to setup OpenMeetings.

Update system:

# yum update

First of all modify Selinux Security level to permissive mode.

vi  /etc/selinux/config

Set SELINUX value as Permissive.

SELINUX=Permissive

Start Installing required packages:

# yum install wget gcc-c++ unzip zlib-devel libjpeg-devel freetype-devel giflib-devel ghostscript ImageMagick sox gedit wget

Make sure that LibreOffice is installed.

Configure MySQL Database for OpenMeetings

Create database password for root user:

# yum install mysql-server mysql
# service mysqld  start

Create MySQL password for root:

# mysqladmin -u root password "password"

Create database database named ‘openmeetings’ and a database user ‘openmeetings’, assign password to that user.

# mysql -u root -p 
mysql> CREATE DATABASE openmeetings DEFAULT CHARACTER SET 'utf8';
Query OK, 1 row affected (0.00 sec)
mysql> CREATE USER 'openmeetings'@'localhost' IDENTIFIED BY 'openmeetings';
Query OK, 0 rows affected (0.00 sec)
mysql> GRANT ALL PRIVILEGES ON openmeetings.* TO 'openmeetings'@'localhost';

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

Now we need to install various add on  tools required to configure openmeetings.

Install LAME

It is an open source tool used to compress audio to mp3 format.

# curl -L -O http://downloads.sourceforge.net/project/lame/lame/3.99/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

Install swftools

Tool is required to support .swf file formats.

cd /opt

# wget http://www.swftools.org/swftools-2013-04-09-1007.tar.gz

# tar -xvf swftools-2013-04-09-1007.tar.gz

# cd swftools-2013-04-09-1007

# ./configure --libdir=/usr/lib --bindir=/usr/bin

# make

# make install

Install Jodconverter

A document converter which converts various office formats.

# /opt

# wget http://jodconverter.googlecode.com/files/jodconverter-core-3.0-beta-4-dist.zip

# unzip jodconverter-core-3.0-beta-4-dist.zip

Install ffmpeg

A tool used to convert and stream audio, videos.

# 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

Download and configure JAVA MySQL Connector

A tool used to connect OpenMeetings with mysql.

# 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

Finally install openmeetings:

# mkdir /openmeetings && cd /openmeetings 
# wget http://ftp.cixug.es/apache/openmeetings/3.0.7/bin/apache-openmeetings-3.0.7.zip

Unzip package:

# unzip apache-openmeetings-3.0.7.zip

Now copy .jar file from Mysql-connector folder to /openmeetings/webapps/openmeetings/WEB-INF/lib.

# cd ~/mysql-connector-java-5.0.8
# cp mysql-connector-java-5.0.8-bin.jar  /openmeetings/webapps/openmeetings/WEB-INF/lib

Go to /openmeetings/webapps/openmeetings/WEB-INF/classes/META-INF/ and get backup of persistence.xml.

# cd /openmeetings/webapps/openmeetings/WEB-INF/classes/META-INF/
# cp persistence.xml persistence.xml.backup_rku

Rename mysql_persistence.xml to persistence.xml:

# cp mysql_persistence.xml persistence.xml

Edit persistence.xml and provide username and password details

#nano persistence.xml

Sample Output:

 
<property name="openjpa.ConnectionDriverName" value="org.apache.commons.dbcp2.BasicDataSource" />
<property name="openjpa.ConnectionProperties"
value="DriverClassName=com.mysql.jdbc.Driver
, Url=jdbc:mysql://localhost:3306/openmeetings?autoReconnect=true&amp;useUnicode=true&amp;createDatabaseIfNotExist=true&amp;cha$
, MaxActive=100
, MaxWait=10000
, TestOnBorrow=true
, poolPreparedStatements=true
, Username=openmeetings
, Password=openmeetigns" />
<property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema" />
<property name="openjpa.Log" value="DefaultLevel=WARN, Runtime=INFO" />

Ok, now you are very close to finalize Apache Openmeetings server configuration.

Navigate to /openmeetings folder and run red5.sh script:

# cd /openmeetings
# ./red5.sh

After script run is over do not close terminal and run apache service through new terminal.

# service httpd start

Open Browser and type <ip_addr>:5080,  a welcome window will appear, proceed to next screen.

Note: One important thing to note is that I got error while running red5.sh script with updated Java version, but when I tried to configure this application with older version i.e. 1.7, it worked successfully.

Have Fun!
