RealSystems Helix Universal Server

The Helix Universal Media Server is the only universal platform with support for live and on-demand delivery of all major file formats, including Real Media, Flash, Windows Media, QuickTime, MPEG 4, MP3, and more. It also accepts live encoder connections for these file formats, increasing content creation flexibility and preserving investments in automated encoding systems.

A full or 30-day trial version of the software is available.

Installation

Download the Helix Universal Server software.

The software is found at the RealNetworks Web site. Be sure to select the correct Operating System for your Virtual Private Server. Note that there is a free 30 day evaluation version, but you will need to purchase a license if you want to continue using Real Server.
- Download Helix Universal Server
Connect to your Virtual Private Server via Telnet or SSH and create an install directory for Real Server.
```
% cd
```
```
% mkdir ~/usr/local/real
```
Upload the Installation software (in BINARY format, if you are using FTP) to this new install directory.
If you entered the registration information correctly when downloading the software, a Real Server license key file will be E-Mailed to you by RealNetworks. RealNetworks offers the following advice for uploading your license key:

Your license file for your Helix Universal Server will be corrupted if it is transferred from one computer to another via FTP as a text document. Doing so will cause changes in the file to the degree that the checksum the Helix Universal Server runs on the installed license file at startup will fail, and the Helix Universal Server will not start. The file can be successfully transferred via FTP as a binary document.
Run the setup utility by issuing the following commands (the example is the file for FreeBSD installation. Change the filename to the name of the file you downloaded from RealNetworks):
```
% cd ~/usr/local/real
```
```
% chmod 755 rs900-freebsd4-ia32.bin
```
```
% ./rs900-freebsd4-ia32.bin
```

The installation program will now run, stopping when it needs further information (outlined below).

Enter directory path to the RealServer license key file
```
/usr/home/LOGIN/usr/local/real/LICENSE-NUMBER.lic
```

Accept End User License Agreement

Choose "Accept" to accept the terms of this
license agreement and continue with RealServer setup.
If you do not accept these terms, enter "No"
and installation of RealServer will be cancelled.
[Default: Accept]:

Enter the complete path to the directory where Helix Server is to be installed. You must specify the FULL pathname of the directory and have write privileges to that chosen directory.
```
/usr/home/LOGIN/usr/local/real
```
Enter a username and password you will use to access the web-based RealSystem Administrator, the RealSystem monitors, and RealSystem live encoders
```
Username: (we suggest you use your VPS login)
Password: (we suggest you use your VPS password)
```

Enter PNA, RTSP, HTTP, and RealServer Administrator, connection port numbers

NOTE: Before accepting the defaults, please verify the ports you select are not already being used, or will interfere with ports in use, on your server. For all of the ports, you must choose a port number greater than 1024.

PNA connections. These connections have URLs that begin with "pnm://"[Default: 7070]:
RTSP connections. These connections have URLs that begin with "rtsp://"[Default: 554]: 5540
HTTP connections. These connections have URLs that begin with "http://"[Default: 80]: 8080

The RealSystem Administrator port will be initialized to a random value for security. Again, verify that selecting this port will not interfere with ports already in use.

The following RealServer configuration will be displayed:

Admin Username:         LOGIN
Admin Password:         PASSWORD
Monitor Password:       PASSWORD
Encoder Username:       LOGIN
Encoder Password:       PASSWORD
PNA Port:               7070
RTSP Port:              5540
HTTP Port:              8080
Admin Port:             1472 (random value)

Enter [F]inish to begin copying files, or [P]revious to go back to the previous prompts: F

NOTE: If there is an error in the list displayed, type P. This will take you back to the username prompt in the installation. For your convenience, the information you originally entered is now the default.

When the setup utility gives you the option to start RealSystem Administrator, type "No". Before you can start the RealServer you must make one other addition to the configuration file

Add the following lines to the end of the rmserver.cfg file:

<List Name="IPBindings">
<Var Address_01="0.0.0.0"/>
</List>

Start the Helix server
```
% Bin/rmserver -m 32 rmserver.cfg
```
You should also add the following line to your Virtual Private Server rc file (~/etc/rc ) so RealServer will automatically start in case of a host machine reboot.
```
~/usr/local/real/Bin/rmserver -m 32 ~/usr/local/real/rmserver.cfg
```

Did It Work?

To make sure Helix Server is running correctly, connect to the RealSystem Administrator using the following URL:

http://YOUR_DOMAIN.NAME:1472/admin/index.html

NOTE: "1472" is the random setting for the RealSystem Admin port used in the example above. Substitute the port number selected by the system/you when you ran the setup utility.

After successfully logging in to the Helix Server, the Admin page will display. The menu on the left will display the following links:
