Building and installing a Red5 server on a Linux box.

Adding a new user

First we create a new user for the Red5 service.

server:~> adduser red5

and deactivate the interactive shell.

red5:x:10xy:10xy:,,,:/home/red5:/bin/false

Installing a Red5 server on a Linux server.

Building a Red5 installer

To get a grip on Red5 we import the source into an IDE and build the server locally using the current stable release (as of May 2010 this is version 0.9.1).

server:~> svn checkout http://red5.googlecode.com/svn/java/server/tags/0_9_1
server:~> mv 0_9_1 red5-server-0.9.1
server:~> ln -s red5-server-0.9.1 red5-server-0.9.x

Look into the interior of the server, adapt code as needed.

server:~> cd red5-server-0.9.x
server:~> ant dist

Create a

server:~> ant dist-installer

Or download the latest release from http://code.google.com/p/red5/ if the binary distribution is all you need.

Add a Red5 server startup script

Based on the /etc/init.d/skeleton a startup script for the installation above could look like this:

#! /bin/sh
### BEGIN INIT INFO
# Provides:          red5-server
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog

# Short-Description: Red5 server script

Starting the Red5 server manually

With the red5-server startup script the Red5 server should start with uid=red5.

server:~> sudo /etc/init.d/red5-server start

Point your web browser to http://localhost:5080/ to verify the basic installation:

Making Red5 script run at boot time

server:~> update-rc.d red5-server defaults
