Rasperry PI :: IPVS on Fedora Remix 18-2
28-01-2013.
1. - Hardware Requirements - 1x per each PI: for | what | why | Vendor ----------------------------------------------------------------------------------- USB Path | Powered USB HUB | Multible USB dev | i.e Belkim IPVS Cluster sync | GPIO RS232 Serial adaper | avoid split brains | https://www.adafruit.com/products/954 Linux Console | usb serial Adapter | Serial Console | multible , look for an linux supported one 2. USB Ethernet 100MB | usb ethernet adapter | Heartbeat sync | multible , look for an linux supported one The 2. usb ethernet may optional . read the http://www.linuxvirtualserver.org/software/ipvs.html pages. Myself hate not stable clusters ;-) . You need an Serial NULLmodem kabel - Google "serial null modem cable" , or look for an local vendor nearby. 2. - Software Requirements : Debian 6 for PI seems NOT deliver the IPVS Modules . Fedora Remix 17/18 seems to deliver the IPVS Modules . As kernel recompile take 6-9h, and i wanted no manual kernel updates, I chosed FC remix 18 rasp !! 3. IPVS Planing IPVS Beginners : RTFM - read the Fucking manuals :-) -> http://www.linuxvirtualserver.org/docs/ha/heartbeat_ldirectord.html -> http://www.linuxvirtualserver.org/software/ipvs.html -> http://www.linux-ha.org/wiki/Pacemaker -> http://www.linux-ha.org/wiki/Heartbeat .. some more wikis exist On Internet for detailed HowTows. 4. IPVS with PI - Hardware setup A -> setup 2 Pi with FC 18 rasp , Both the same config B -> change serial console to /dev/USB01 for this you need to update the boot config , change console= to an USB tty. see this page : http://www.irrational.net/2012/04/19/using-the-raspberry-pis-serial-port/ C -> install an GPIO RS 232 adapter i.e https://www.adafruit.com/products/954 i.e http://wolfpaulus.com/journal/embedded/raspberry_serial D -> Plug an Serial Nullmodem Cabel between the both GPIO RS 232 adapter see : http://en.wikipedia.org/wiki/Null_modem see : http://www.linux-archive.org/centos/188608-cluster-heart-beat-using-cross-over-cable.html Test with minicom : https://nmi.cs.wisc.edu/node/878 If the test hast been succeed in both directions , then you ready to use it for the "ANTI SPLIT BRAIN " crossover heartbeat cable. RTFM.. 5 -> install required IPVS RPMs: [root@lb1 ha.d]# rpm -qa | egrep -e '(ipvsadm|pacemaker|drbd-|httpd-|mon.armv5tel|bind-)' | egrep -v '(libmicro|rpcbind)' bind-dyndb-ldap-2.3-2.fc18.armv5tel drbd-pacemaker-8.3.13-1.fc18.armv5tel bind-lite-devel-9.9.2-6.P1.fc18.armv5tel drbd-8.3.13-1.fc18.armv5tel pacemaker-cli-1.1.8-3.fc18.armv5tel ipvsadm-1.26-6.fc18.armv5tel bind-sdb-9.9.2-6.P1.fc18.armv5tel bind-to-tinydns-0.4.3-9.fc18.armv5tel drbd-heartbeat-8.3.13-1.fc18.armv5tel pacemaker-doc-1.1.8-3.fc18.armv5tel pacemaker-libs-devel-1.1.8-3.fc18.armv5tel pacemaker-cluster-libs-1.1.8-3.fc18.armv5tel bind-libs-9.9.2-6.P1.fc18.armv5tel bind-chroot-9.9.2-6.P1.fc18.armv5tel bind-pkcs11-9.9.2-6.P1.fc18.armv5tel drbd-utils-8.3.13-1.fc18.armv5tel drbd-bash-completion-8.3.13-1.fc18.armv5tel pacemaker-libs-1.1.8-3.fc18.armv5tel pacemaker-1.1.8-3.fc18.armv5tel bind-license-9.9.2-6.P1.fc18.noarch bind-9.9.2-6.P1.fc18.armv5tel bind-devel-9.9.2-6.P1.fc18.armv5tel drbd-udev-8.3.13-1.fc18.armv5tel bind-libs-lite-9.9.2-6.P1.fc18.armv5tel bind-utils-9.9.2-6.P1.fc18.armv5tel pacemaker-cts-1.1.8-3.fc18.armv5tel 6. HA Setup Bring IP apache, bind on each LB. Setup Minimalistc test pages as Wikis suggest Setup NTP Both LB require to have the same date & Time !! Setup i.e Bind as local cache, this speedup lookups for ldirectord. Bring UP heartbeat , configure it Bring UP ldirectord , configure it TEST the cluster , poweroff one LB node, the second must take over ! Asume you have allready REAL servers setup , so start using them Follow i.e http://www.linuxjournal.com/article/9838 / http://www.linuxvirtualserver.org/docs/ha/heartbeat_ldirectord.html ALL well done ?, have FUN ;-) Cheers.
