How to install Red5 Server with Tomcat

Download Java from http://www.sun.com
Install java into a folder such as /opt/red5/jdk-1.6.0
Set JAVA_HOME point to that folder

export JAVA_HOME=/opt/red5/jdk-1.6.0

Download Tomcat from http://tomcat.apache.org/
Extract Tomcat into a folder such as /opt/red5/

cd /opt/red5
wget http://mirror-fpt-telecom.fpt.net/apache/tomcat/tomcat-6/v6.0.18/bin/apache-tomcat-6.0.18.tar.gz
tar -xf apache-tomcat-6.0.18.tar.gz

Download Red5 package from http://osflash.org/red5
The package that we should download is the WAR package http://www.red5.fr/release/0.7.0/war/Red5War_0.7.0.zip
Extract the package into a folder such as /opt/red5/

cd /opt/red5
wget http://www.red5.fr/release/0.7.0/war/Red5War_0.7.0.zip
tar -xf Red5War_0.7.0.zip

The 3 WARs file will be extracted
- ROOT.war: the main Red5 application
- admin.war: the Red5 admin page
- echo.war: the echo sample application
Move 3 WARs into tomcat/webapps folder

cd /opt/red5
mv ROOT.war admin.war echo.war apache-tomcat-6.0.18/webapps

Remove the default ROOT application of Tomcat

cd /opt/red5/apache-tomcat-6.0.18/webapps
rm -rf ROOT

Create a start-server.sh file for easy to startup with following content

export JAVA_HOME=/opt/red5/jdk-1.6.0
export CATALINA_HOME=/opt/red5/apache-tomcat-6.0.18
export PATH=$JAVA_HOME/bin:$PATH
cd $CATALINA_HOME
./bin/startup.sh

Start Tomcat with start-server.sh

cd /opt/red5
./start-server.sh

Open the browser and browse to the following URL http://[ip]:8080/
The Red5 welcome page will be displayed
You can test the RTMP broadcast via web at http://[ip]:8080/demos/ofla_demo.html or via client application such as VideoLAN rtmp://[ip]/oflaDemo/DarkKnight.flv
You might want to create the stop-server.sh to stop Tomcat with following contents

export JAVA_HOME=/opt/red5/jdk-1.6.0
export CATALINA_HOME=/opt/red5/apache-tomcat-6.0.18
export PATH=$JAVA_HOME/bin:$PATH
cd $CATALINA_HOME
./bin/shutdown.sh

The trojan modify some registry at TcpIp service and maybe it also adds some Windows service for monitoring...
