How To Install RED5 Server on Centos 5.3

on August 16 | in Hosting / Servers, Linux | by | with 481 Comments

In this how to i will describe how to install RED5 server on Centos 5.3. This how to can be used to install RED5 server on Centos 4 and Fedora 8 – 11 as well. 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) 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/

3) 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

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: ”
$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


you will see red5 page like this


and demos can be find here.



You can use simple port tester tool that determines which ports the Flash Player is able to connect through to the Red5 server. Put your server address or IP in HOST when using port tester. You should get SUCCESS on RTMP or port 1935. If not please check your firewall.




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.

If you any question please use comments.

    @ heru minandar,

    First thing, thanks for providing your exact URL to your Red5 server, I can now use it and get free bandwidth. :)
    I highly recomment you remove that link ASAP.
    Second, you did not follow the instructions %100.
    Third, you cannot open the demos simply because you have not installed any.

    Install a ready-made application by clicking the red install link.
    Install ofla demo and then you will see the demo. I could have done this for you seeing you provided a link but I am not like that.

  2. Heru Minandar says:

    I already done with install oflademo because when I try again I get this message:
    Application oflaDemo already installed, please un-install before attempting another install

  3. red5 server says:

    Thanks for the useful information. I really need this topic to share with my friends

  4. al3x says:

    Running it as root is insecure.
    You need to lower privileges to user red5 (fore example).
    1. adduser -d/usr/local/red5 -s/bin/false red5
    into /etc/init.d/red5 add
    USER=”red5″ and in start) replace
    $DAEMON >/dev/null 2>/dev/null &
    daemon –user=$USER $DAEMON >/dev/null 2>/dev/null &
    then it should drop privileges to red5

  5. JuceLan says:

  6. Dean says:

    @ JuceLan

    Update ant

  7. Dean says:
