2) Download and Install Ant (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
wget http://mirrors.kahuki.com/apache/ant/binaries/apache-ant-1.8.0-bin.tar.bz2
tar jxvf apache-ant-1.8.0-bin.tar.bz2
mv apache-ant-1.8.0 /usr/local/ant

3) Export Variables for Ant and Java

export ANT_HOME=/usr/local/ant
export JAVA_HOME=/usr/lib/jvm/java
export PATH=$PATH:/usr/local/ant/bin
export CLASSPATH=.:$JAVA_HOME/lib/classes.zip

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=$PATH:/usr/local/ant/bin’ >> /etc/bashrc
echo ‘export CLASSPATH=.:$JAVA_HOME/lib/classes.zip’ >> /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 http://red5.googlecode.com/svn/java/server/trunk/ 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

The init script code also be viewed below. following script on works with fedora or redhats, for ubuntu edit cron with command ‘crontab -e’ and add  ‘@reboot cd /usr/local/red5/ ; ./red5.sh & >/dev/null 2>&1’ and now reboot

# 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

chmod a+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.
