Separate TFTP and DHCP Server
Separate TFTP and DHCP Server
In this setup, the TFTP server and the DHCP server are hosted on a separate server. The TFTP server holds the PXE boot files including the Linux Kernel, boot file system image, and pxe config files. The DHCP server is the server that assigns the clients with IP addresses and network connection information.
In this setup we will have two servers:
- Server A: This is the 'Master' server which will host Apache, MySql, NFS and HTTP
- Server B: This server will host TFTP and DHCP
In our example, both of these servers need to have a fresh install of Fedora. They will both need static IP addresses, in our example we will use:
- Server A: 192.168.1.50
- Server B: 192.168.1.51
On both nodes, download the FOG installation package from:
http://sourceforge.net/project/showfiles.php?group_id=201099
On Server A install FOG, when you are prompted with:
Would you like to use the FOG server for dhcp service? [Y/n]
Select "n" to not start DHCP on that server.
After installation is complete navigate to:
http://localhost/fog
and install the FOG schema.
On server A go to:
System -> Administration -> Services
Uncheck and Stop the following Services:
- dhcpd (should already be stopped.)
- xinetd
- vsftpd
On Server B install FOG, but this time install the dhcp service.
On server B go to:
System -> Administration -> Services
Uncheck and Stop the following Services:
- FOGMulticastManager
- httpd
- mysqld
On server B open:
/var/www/html/fog/commons/config.php
Copy the value from TFTP_FTP_PASSWORD
Then open
/tftpboot/pxelinux.cfg/default
Replace all instances of web=x.x.x.x/fog/ with the the ip address of Server A.
Now on Server A, open:
/var/www/html/fog/commons/config.php
Replaced the value from TFTP_FTP_PASSWORD on Server B.
To test your configuration, navigate to
http://192.168.1.50/fog
login as:
Username: fog Password: password
Create a host and then attempt to create a task, if everything works correctly you should see a file created on Server B in the directory /tftpboot/pxeconfig.pxe/ name with the mac address of the host.
