| − | Installfest "Services" is an working proof-of-concept by [[User:Bseklecki | Brian A. Seklecki]] and [[User:trodgers | Ted Rodgers]] to provide high performance servers for Linux Distro Boot, Install Media, and Updates retrieval via a local FTP/HTTP/RSYNC/NFS mirror within the Installfest event LAN.
| + | The service runs on local hardware in the LAN. Having local install/update mirrors avoids the need for [[WPLUG]] attendees to consume Commodity Internet (commercial upstream Internet Connectivity) at the [[InstallFest]] venue. |

| + | The current configuration will provide PXE extensions via DHCP requests. The PXE code in the BIOS will TFTP download the 1st/2nd stage bootloader from the server. Currently the system is configured to hand out Fedora 10 i386 bootloader code to all clients. <br> |
| | | | |
| − | The current configuration of services provides a PXE environment. There PXE magic is a simple 'next-server' and 'boot-file' flags provided to the client via an extended attribute via DHCP offer reply (DHCP options 66/150).
| + | Specific client MAC addresses can get specific bootloader code upon request. <br> |
| | | | |
| − | The PXE code in the BIOS of your device will translate extra data into a TFTP client download the 1st/2nd stage boot loader from the server. Currently the system is configured to hand out Redhat/Fedora 'intermediate' boot loader clients from the [http://www.syslinux.org/wiki/index.php/The_Syslinux_Project Syslinux] project. <br>
| + | After the boot loader starts, select DHCP auto network configuration (DHCP will renew from the BIOS to the OS). <br> |

| − | = Behind the Scenes =
| |
| − |
| |
| − | The system is run on a Redhat6 or Fedora16+ system (previously NetBSD)
| |
| − |
| |
| − | The system is composed of:
| |
| − | * TFTP Service (defaults to an export of path ''/var/lib/tftp'' with read-only permissions)
| |
| − | * PXE Loader file system directory hierarchy
| |
| − | * PXE Loader menu config file
| |
| − | * Various bootloader code manually located in /var/lib/tftp (from various install CD/DVD images)
| |
| − | * Apache server and Media/Update directory hierarchy
| |
| − |
| |
| − | More details soon.
| |

| |
| − | == Setup ==
| |
| − |
| |
| − | After a base install, RHEL6 and F16 often lack a yum repo for the DVD media.
| |
| − |
| |
| − | * '''server% sudo vim /etc/yum.repos.d/rhel-media.repo
| |
| − |
| |
| − | [rhel6-media]
| |
| − | name=RHEL-$releasever - Media

| |
| − | enabled=1
| |
| − | gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
| |
| − |
| |
| − | * Install the various packages:
| |
| − |
| |
| − | '''server% sudo yum install xinetd tftp-server dhcp syslinux'''
| |
| − |
| |
| − | * Enable TFTP Service
| |
| − |
| |
| − | '''server% sudo vim /etc/xinetd.d/tftp && /sbin/service xinetd restart"
| |
| − | disable = no
| |
| − |
| |
| − | * Copy the various syslinux files into place
| |
| − |
| |
| − | '''server% sudo cp /usr/share/syslinux/{pxelinux.0,vesamenu.c32} /var/lib/tftpboot'''
| |
| − | '''server% mkdir /var/lib/tftpboot/pxelinux.cfg'''
| |
| − |
| |
| − | * Populate the default config with a menu
| |

| |
| − |
| |
| − | '''NOTE:''' Setup a menu item for each distro. They vmlinuz and initrd will be relative to ''/var/lib/tftp'' and should reside in sub-directories.
| |
| − |
| |
| − | * For each distro (rhel58,rhel62) copy the ''vmlinuz'' and ''initrd.img'' from the install (not the LiveCD) media
| |
| − | '''server% sudo mkdir -p /var/lib/tftpboot/rhel62 && cp /media/cdrom/isolinux/{initrd.img,vesamenu.c32} /var/lib/tftpboot/rhel62'''
| |
| − |
| |
| − | * TFTP boot and load your end user device (permutations for i386/x86_64 will be required)
| |
| − |
| |
| − | * Install Apache for the local media and updates service
| |
| − |
| |
| − | NOTE: Make sure that ~500 gigs of space is available on '''/export'''
| |
| − |
| |
| − | * Setup /etc/httpd/conf.d/wplug-services.conf
| |
| − |
| |
| − | [Sample Soon]
| |
| − |
| |
| − | * Setup a cron job to rsync a local copy of the redhat updates:
| |
| − |
| |
| − | '''server% mkdir -p /export/services/linux/rhel/62 /export/services/linux/fedora/16'''
| |
| − |
| |
| − | * Setup IPTables rules to permit inbound on 67,68,68, etc for DHCP/BOOTP and TFTP
| |
| − |
| |
| − | % sudo iptables -L
| |
| − | ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh
| |
| − | ACCEPT udp -- anywhere anywhere state NEW udp dpt:tftp
| |
| − | ACCEPT udp -- anywhere anywhere state NEW udp dpts:bootps:bootpc
