RED5 is open source flash server written in java supports streaming audio/video, recording client streams, shared objects, live stream publishing etc.

1) Download and Install Java

RED5 server depends on Java. CentOS 5.3 comes with OpenJDK 1.6 and install it using yum.

yum -y install java-1.6.0-openjdk java-1.6.0-openjdk-devel

2) Export Variables for Ant and Java

export ANT_HOME=/usr/local/ant
export JAVA_HOME=/usr/lib/jvm/java
export PATH=$PATH:/usr/local/ant/bin

Also export these variables in /etc/bashrc to become available for every user login or for any terminal opens.

echo ‘export ANT_HOME=/usr/local/ant’ >> /etc/bashrc
echo ‘export JAVA_HOME=/usr/lib/jvm/java’ >> /etc/bashrc
echo ‘export PATH=$PATH:/usr/local/ant/bin’ >> /etc/bashrc

3) Download and Install Ant & Ivy (Apache Project)

Ant will need to compile RED5 server code. Ant comes in binary form, so just download and install it in /usr/local directory.

cd /usr/src
tar jxvf apache-ant-1.8.2-bin.tar.bz2
mv apache-ant-1.8.2 /usr/local/ant
cd /usr/src
svn co ivy
cd ivy
ant jar
cp build/artifact/jars/ivy.jar /usr/local/ant/lib/

4) Download and Install RED5 Server

Here the latest version available for RED5 is 0.7 on site but download from google code using svn as the tarball of 0.7 on site is missing some of the files.

cd /usr/src
svn checkout red5
mv red5 /usr/local/
cd /usr/local/red5
ant prepare
ant dist

you will see a ton of lines, but you should get at last


that’s mean its install and now copy the conf directory from dist/ and test the red5 installation.

cp -r dist/conf .

If it shows Installer service created in the last then everything is fine here, press ctrl+c and move to next step to create init script.

5) Init Script

Now we will create init script for red5 to start, stop and restart easily.

vi /etc/init.d/red5

download and copy / paste code in it. The init script code also be viewed below.

# For RedHat and cousins:
# chkconfig: 2345 85 85
# description: Red5 flash streaming server
# processname: red5

# Source function library
. /etc/rc.d/init.d/functions

[ -r /etc/sysconfig/red5 ] && . /etc/sysconfig/red5


case "$1" in
	echo -n $"Starting $PROG: "
	cd $RED5_HOME
	$DAEMON >/dev/null 2>/dev/null &
	if [ $RETVAL -eq 0 ]; then
		echo $! > $PIDFILE
		touch /var/lock/subsys/$PROG
	[ $RETVAL -eq 0 ] && success $"$PROG startup" || failure $"$PROG startup"
	echo -n $"Shutting down $PROG: "
	killproc -p $PIDFILE
	[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$PROG
	$0 stop
	$0 start
	status $PROG -p $PIDFILE
	echo $"Usage: $0 {start|stop|restart|status}"

exit $RETVAL

Enable executable permission

chmod +x /etc/init.d/red5

Now start the service

/etc/init.d/red5 start

Check status

/etc/init.d/red5 status
red5 (pid  XXXXX) is running…

Again you can do stop, restart.

6) Test

Now test the RED5 installation by opening following URL in browser


7) Toubleshooting.

When you run ./, it will show you Installer service created. Thats mean everything runs fine and red5 server is up. But if you went to port_tester.swf using demos above or your application shows connections FAILS, this is an issue of RTMPT and RTMPTS. You can see it by running


output trancated

[INFO] [main] org.red5.server.tomcat.TomcatLoader – RTMPT server bean was not found
[INFO] [main] org.red5.server.tomcat.TomcatLoader – RTMPS server bean was not found

output truncated

If you see this you have to uncomment the RTMPT and RTMPTS TomcatLoader in/usr/local/red5/conf/red5-core.xml

vi /usr/local/red5/conf/red5-core.xml

Search for a lines

<!– RTMPT –>
<bean id=”rtmpt.server” class=”” init-method=”init” lazy-init=”true”>

Remove the <!– from start of <bean and –> from end of </bean>

Same goes for RTMPS

<!– RTMPS –>
<bean id=”rtmps.server” class=”” init-method=”init” lazy-init=”true”>

Remove the <!– from start of <bean and –> from end of </bean>

Restart the red5 services and connection fails problem will be fixed.
