java -version

Installation of LibreOffice

OpenMeetings will need LibreOffice to convert to pdf the uploaded office files.

We install it:

yum -y install libreoffice libreoffice-headless

Installation of  necessary packages and libraries  

We install packages and libraries that we´ll need later:

  (Only one line with space between 1ª and 2ª)

yum install -y libjpeg libjpeg-devel ghostscript freetype freetype-devel  unzip gcc gcc-c++ ncurses ncurses-devel make zlib zlib-devel libtool bison bison-devel openssl-devel bzip2 bzip2-devel fileroller git autoconf automake pkgconfig tomcat-native nmap nano

yum install -y flash-plugin

Compilation of FFmpeg

Install Nux Dextop Yum Source
Because CentOS has no official FFmpeg rpm package. However, we can do this with a third-party YUM source (Nux Dextop).

For CentOS 7

rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm

For CentOS 6

rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
rpm -Uvh http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-2.el6.nux.noarch.rpm

Install FFmpeg and FFmpeg Development Kit

yum install ffmpeg ffmpeg-devel -y

Test whether the installation is successful

ffmpeg

I have a good script here can be installed directly...

wget https://github.com/syavingc/Scripts/blob/master/shell/install_ffmpeg.sh
chmod +x install_ffmpeg.sh 
./install_ffmpeg.sh

Installation MariaDB database server

We build a file-repository to download MariaDB data server.

For Centos 6.x  64 bit:                                                                                                                                            

vim /etc/yum.repos.d/MariaDB.repo

...copy and paste in:

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

We install it:

yum -y install MariaDB-server MariaDB-client

...do a backup of  the configuration file; and make a newone:

mv /etc/my.cnf /etc/my.bak
cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

...and run MariaDB server:

service mysql start

Give a password to mariadb root . Please, replace new-password by your own whish.

mysqladmin -u root password new-password

Make a database for OpenMeetings. User password must be of 8 digits minimum:

mysql -u root -p

...will ask for the root password we does just now:

MariaDB [(none)]> CREATE DATABASE open40 DEFAULT CHARACTER SET 'utf8';          

With this command, we has created a database called open40, though you can choose another name to your whish.

Now we create a user with all the permission on this open40 database.

(Only one line with space between both)

MariaDB [(none)]> GRANT ALL PRIVILEGES ON open40.* TO 'hola'@'localhost' IDENTIFIED BY '1a2B3c4D' WITH GRANT OPTION;                   

open40 .....…........ name of the database

hola        .....…........ user for that database                                                

1a2B3c4D  ..............password of that user

You can change the data...but remember it! Later we´ll need it.

Leave MariaDB:

MariaDB [(none)]>  quit     

Installation of OpenMeetings

We´ll install OpenMeetings in /opt/red540. All the following information will be based on this directory.

Call to our folder of installation red540.

Make the folder:

mkdir /opt/red540
cd /opt/red540

...and download the OpenMeetings file:

wget http://apache.miloslavbrada.cz/openmeetings/4.0.0/bin/apache-openmeetings-4.0.0.zip
unzip apache-openmeetings-4.0.0.zip

...save the unloaded file to /opt:

mv apache-openmeetings-4.0.0.zip /opt

Download and install the connector between OpenMeetings and MariaDB:

cd /opt                                             

    (Only one line without space between both)

wget http://repo1.maven.org/maven2/mysql/mysql-connector-java/5.1.42/mysql-connector-java-5.1.42.jar

...and copy it to where must be:

 cp /opt/mysql-connector-java-5.1.42.jar /opt/red540/webapps/openmeetings/WEB-INF/lib

 Now we are going to configure OpenMeetings for our database in MariaDB:

vim /opt/red540/webapps/openmeetings/WEB-INF/classes/META-INF/mysql_persistence.xml

 

chmod 640 /opt/red540/webapps/openmeetings/WEB-INF/classes/METAINF/mysql_persistence.xml

Script to launch red5-OpenMeetings

We´ll download the script to run Red5-OpenMeetings:

cd /opt
wget https://cwiki.apache.org/confluence/download/attachments/27838216/red5-2

...copy it to where must be:

cp red5-2 /etc/init.d/

...concede execution permission:

chmod +x /etc/init.d/red5-2         

If you made the installation in any other different path to /opt/red540, please edit the script and modify the line:

RED5_HOME=/opt/red540

...to

RED5_HOME=/your-path-installation

Run red5-OpenMeetings

Restart mariadb:

service mysql restart

...and run red5-OpenMeetings. Please, be connected to Internet, so the run will be quick:

/etc/init.d/red5-2 start                                                                                                  

...wait untill the text “CleanupJob.cleanRoomFiles”, it is the last in the shell. Then, go with the browser to: 

Browser    http://localhost:5080/openmeetings/install

...there will appear a page similar to this one:

...press on  (>) button(bottom), and will show the default database configuration with Derby,

but we employ MySQL (MariaDB):

 

...then, scroll and Choose DB type to MySQL:

 

...will show the database name we made in step 11.

If you`ve choose any other different name for this, will show equally.

Now we must introduce the user name we did for our data base, at the step 8, and his password:

Specify DB user   =   hola

Specify DB password   =  1a2B3c4D

Please, press    (>)  button, and we´ll go to:

 

Here, we must introduce a user name for OpenMeetings, and his password. This must have 8 digits minimum, and at least 1 special symbol like:   + ( % # !    ...etc.

Username  =     a-name   ...this user will be administrator.                                

Userpass    =     a-password ...for the previous user.

Email         =     email-adress ...of the previous user.

User Time Zone   =    country where is this server

Name         =     example-openmeetings  ...group name to choose.

Press the button   (>)  and will lead us to a new page (below) where you can select the language for your OpenMeetings server, as well as other options such as the configuration of the mail server being used to send invitations or meetings from OpenMeetings.

A valid example to configure the mail server with Gmail, is as follows:

(replace john@gmail.com with your real Gmail account)

Mail-Refer                                                   ==      john@gmail.com

SMTP-Server                                              ==      smtp.gmail.com

SMTP-Server Port (default Smtp-Server Port is 25)                              ==      587                                                                  

SMTP-Username                                        ==      john@gmail.com

SMTP-Userpass                                          ==      password of john@gmail.com

Enable TLS in Mail Server Auth              ==      ...turn green the button to activate

...the rest we you can modify it as you like it.

Now press the button    (>)and a new page will appear:

Here we´ll introduce the respective paths for the image, video, audio and conversion of uploaded files:

 ImageMagick Path     ==    /usr/bin

FFMPEG Path             ==    /usr/bin

SOX Path                     ==   /usr/local/bin

jodconverter                                      ==   /usr/lib64/libreoffice    (64bits)                                                                                         

Once completed the paths, please click the       (>)  button and move on to another page that would be to activate the SIP.

 We will leave it as is, unless you want to activate it knowing what it does:
