Blue Linux installation over NFS


Blue Linux can be installed from a centrally located server.Unattended installations from an installation server are highly convenient if you must (re)install, upgrade, tune a large number of networked clients, or install Blue Linux on machines that are geographically dispersed, or do not have access to a cd-rom drive. The installation source and configurations for your client machines are centrally located, making them easier to maintain.

Server Configuration

You must have a system that has access to a cdrom drive or a copy of the Blue Linux installation cd. This system must have DCHP installed and configured.

DHCP Configuration

On your install server, create a Lizard directory structure under lizard in your network installation source directory. With this, your lizard directory is parallel to your CD mount points. This is the default location where Lizard looks for this information. The DHCP entry needs to specify the location in the filename entry. A sample DHCP entry in /etc/dhcp/dhcpd.conf appears as the following:

default-lease-time            21600;
max-lease-time                21600;
    
option subnet-mask            255.255.255.0;
option broadcast-address      192.168.0.255;
option routers                192.168.0.254;
option domain-name-servers    192.168.0.254;
option domain-name            "bluelinux.org";
option root-path              "192.168.0.254:/share/BlueLinux/cd1/";
    
shared-network WORKSTATIONS {
    subnet 192.168.0.0 netmask 255.255.255.0 {
    }
}
    
group	{
    use-host-decl-names       on;
    
    host ws001 {
        hardware ethernet     00:E0:18:E0:04:82;
        fixed-address         192.168.0.1;
        filename              "/share/BlueLinux/cd1/";
    }
} 



In this case, the installation source directory appears as the following:

/share/BlueLinux/lizard
/share/BlueLinux/cd1

If DHCP is not currently setup for this system, or you want to override the DCHP settings, you can use the er=asknet parameter at the command line to specify the hostname,IP address, netmask, broadcast address, default router, DNS server, and NFS installation server and path. To install from an installation server, use the boot parameter lizard=auto with the boot disk.
