Change FOG Server IP Address

Procedural Steps

  • Follow appropriate steps for your Linux distribution to change the
    OS's IP address.
  • Update the ipaddress= field (and other fields if necessary) inside
    the /opt/fog/.fogsettings file .fogsettings
  • Rerun the installer, you'll need to use --recreate-CA and
    --recreate-keys keys as the installer provides a certificate
    with a Common Name based on the ip which will be shipped in the iPxe
    kernel and failed to load any https resources as the certificate
    isn't valid anymore.
  • Update the IP address inside /tftpboot/default.ipxe (look for the
    chain line i.e
    chain https://x.x.x.x/fog/service/ipxe/boot.php##params)
  • Update the IP address for the storage node on the FOG system where
    you changed the IP address Web Interface Storage Management
  • Update the IP address on a any master storage node that may
    reference this FOG server Web Interface Storage Management
  • (For master server) Update the FOG_WEB_HOST value Web Interface
    FOG Configuration FOG Settings Web Server FOG_WEB_HOST
  • (For master server) Update the FOG_TFTP_HOST value Web Interface
    FOG Configuration FOG Settings TFTP Server FOG_TFTP_HOST

Optionaly if you have configured a dhcpd:

  • Update IP addresses (fog and gateway) inside the
    /etc/dhcp/dhcpd.conf.
  • Don't forgot to check your /etc/export for nfs server as well as
    your apache2 configuration as the installer override it.
