We are starting with a fresh Ubuntu 9.04 install (using ubuntu-9.04-server-amd64.iso). The only software selected during installation was OpenSSH Server.

After installation, assign a static IP address and log in remotely with putty (see Ubuntu Setting Static IP Address).

Execute the following command to update apt packages:

sudo apt-get update

Install Subversion so you can download code from google code:

sudo apt-get install subversion

Press Y for yes

Repeat to install java package:

sudo apt-get install java-package

Repeat to install java jdk:

sudo apt-get install sun-java6-jdk

When the Sun License Agreement page comes up, use the right arrow key to select OK and press Enter to continue

Press the Left Arrow and select Yes to agree

Repeat to install ant

sudo apt-get install ant

Next we will download Red5 source code from googlecode. Create a temporary directory to download the code

mkdir -p ~/svn/red5

Change directories to go to the red5 code directory

cd ~/svn/red5

Now execute the following command to download the code:

svn checkout http://red5.googlecode.com/svn/java/server/trunk/ red5-read-only

Execute the following two commands to set environment variables in order to compile the code:

export JAVA_HOME=/usr/lib/jvm/java-6-sun

export ANT_HOME=/usr/share/ant/

Change directories to the red5-read-only directory:

cd ~/svn/red5/red5-read-only

Execute the ant command to compile the code:

/usr/share/ant/bin/ant

The source code will be compiled into the dist directory. This will take a couple minutes.

Next, we will create a permanent directory where the final red5 installation will go:

sudo mkdir /usr/share/red5

Change directories to the dist directory:

cd ~/svn/red5/red5-read-only/dist

Copy all of the files to the new red5 directory:

sudo cp -R * /usr/share/red5/

Change directories to the new red5 directory and change permissions on the red5 startup script to allow it to be executed:

cd /usr/share/red5

sudo chmod 755 red5.sh

Execute the following command to start the red5 server:

/usr/share/red5/red5.sh &

After server starts up, you can access the web console by entering the following URL in your browser:

http://IPADDRESS:5080

If this screen comes up your installation was a success. Follow the instructions thru the web console to install and test out the demos.
