Setting Up Your Pxe Server; Setting Up The Pxe Installation Software - Juniper MEDIA FLOW CONTROLLER 2.0.4 Installation Manual

CHAPTER 4 Installing Media Flow Controller with PXE

Setting Up Your PXE Server

Set up your PXE server configuration file with required information and, optionally, installation
options described in
To set up your PXE server for Media Flow Controller installation:
1. Put these two PXE install package files, both have the same <unique ID> string, into your
PXE server tree:
rootflop-mfc-<uniqueID>.img
vmlinuz-bootflop-mfc-<uniqueID>
2. Edit the PXE server configuration file on your system to make these available for booting
from. For example, if the uniqueID string in the Media Flow Controller filenames is 2.1.0,
and you place them in a directory named mfc-install, and you want to have the PXE
menu for using them be "mfc-install-2.1.0," then, on a Redhat Linux PXE server, edit
pxelinux.cfg/default to add a "LABEL" line, a "kernel" line, an "append initrd" line, and an
"IPAPPEND" line, as shown. You can add installation options on the "append initrd" line;
see "PXE Installation Options" on page 37
LABEL mfc-install-2.1.0
kernel mfc-install/vmlinuz-bootflop-mfc-2.1.0
append initrd=mfc-install/rootflop-mfc-2.1.0.img panic=10 noexec=off
console=ttyS0,9600n8 console=tty0 ramdisk_size=16384 rw
installopt=accept-eula
IPAPPEND 3
Note!
"PXE Installation Options" on page 37
3. Edit the bootmsg.txt file to add a line that references the label you used:
<uniqueLabel> <description text>
Using the values given, this would be:
mfc-install-2.1.0 Juniper Networks Media Flow Controller installation

Setting Up the PXE Installation Software

The described PXE server setup makes it possible to boot up an environment that allows you
to install from the actual Media Flow Controller distribution files. There are two distribution files
in the Media Flow Controller PXE installation package, a matched pair; one is the image*.img
file and the other is the manufacture*.gz file; the image*.img file is the same file you use for
upgrades. You need to put these both in a directory on a Web server so the machine being
installed can download the files via HTTP. It is best to put the two files in the same directory
where you put the rootflop and vmlinuz files (see Step
page 36).
Sample filenames for these are:
image-mfc-2.1.0-rc_5_10705_180.img
manufacture-mfc-2.1.0-rc_5_10705_180.tgz
For example, if the "append initrd" parameter you configured in the PXE configuration file, is
initrd=pxe/mfc-install/rootflop-mfc-2.1.0.img, then the HTTP URL where the image and
manufacture files are located should be:
http://<pxe_server_name>/pxe/mfc-install/
