Ubuntu Servers :: Setup An Apache Web Cluster Using Red Hat Cluster Suite
Sep 1, 2011I am working in a project that needs to set up an Apache Web Cluster. The cluster needs to be High-availability (HA) cluster and Load-balancing cluster. Someone mentioned the use of Red Hat Cluster Suite, but, honestly, I can't figure out how it works, I haven't been able to configure it correctly. The project currently have two nodes, but we need to support at least three nodes in the cluster.

Nov 6, 2010I am trying to build GFS2 cluster with 2 or 3 Fedora 14 nodes, but I've encountered some problems from the start. First luci does not work at all in Fedora 14. There is no luci_admin and even if I manage to start luci service, I get a blank white screen when I try to open it from the browser. I've googled a bit and found that I'd might be able to setup GFS if I manage to build cluster.conf manually and start the cluster suite, but I cannot find documentation on how to create cluster.conf anywhere. If anyone knows how to setup GFS2 without a cluster suite or how to configure cluster.conf.

Apr 28, 2010I'm trying to build a Fedora 12 cluster to run DHCP on top of two servers using pacemaker and drbd. The pacemaker runs great but i'm having the hardest time getting DRBD installed.
My kernel version is 2.6.32.11-99.fc12.i686.PAE First i tried to [root@dhcp-primary drbd]#yum install drbd this doesn't give me everything because apparently the kernel module for DRBD must be built from source. so i unpacked drbd-8.3.6.tar.gz and tried :

Ubuntu Servers :: Setup A Cluster Using Heartbeat?
Jun 29, 2010I am currently trying to setup a cluster using heartbeat. Unfortunatly it does not do what I want to do. I am using heartbeat 2.1.4-11 on a readhat system. I am using the the cib for configuration. What I want to do is the following: I have two Nodes. I want to run a clone resource on both nodes. It's named I want to run as a clone. This works fine.Additionally I want to have two virtual IP adresses. One should be set on Node 1 the other on Node 2. This works fine as well. I want to set dependencies between the resources. And this is where I have problems. What I want to achive: In case named is not able to run on a node, the vIP should switch to the other node (which then will have both vIPs). In case both nodes are able to run named, there should be one vIP on each node. Sounds simple, but does not work.Accourding to the heartbeat docu this an be achieved by using

Fedora Servers :: Setting Up A Cluster For Scientific Computing?
Mar 2, 2010I want to set up a cluster for scientific computing (mainly statistical stuff with R). I have a few conceptual questions. First, is there a difference between a Beowulf cluster and a cluster that has single-system image ("SSI," e.g. using openSSI or LinuxPMI)? If so, what's the difference? Second, if there is a difference between Beowulf and SSI, which one is better for scientific computing? Third, does using Eucalyptus make sense for scientific computing or is this more suitable for IO-oriented operations such as web service or databases
View 2 Replies View RelatedRed Hat / Fedora :: Use Storage On Multiple Servers As A Single Cluster?
Apr 20, 2011Can ANYONE point me in the right direction on how to use storage on multiple servers as a single cluster?I thought storage cluster was for that but, after much googling, and even more help from here, I don't think that achieves my goal. My goal is to have multiple servers share a file system, to act as somewhat of a network raid, so if node-A goes down the files are available on other nodes, and hopefully so when the capacity of the nodes are reached I can add nodes to expand the "cluster".
View 6 Replies View RelatedUbuntu Servers :: Create Script To Keep Machine Cluster Synced Properly Until Failover
Apr 26, 2010I've been reading up on clustering a bit and want to create simple 2 machine cluster of which the 2nd one will turn on and take over traffic at the previous machine's IP (I'm aware there will be a couple minutes of downtime while the failover server boots). I've looked into doing a simple DNS round robin, but I think both machines would need to be online all the time for this to function correctly. I've also looked into linux-HA and GlusterFS but both seem a little intense for the simple failover I'm trying to achieve. One catch if approaching with DNS round robin... the server that I want to setup with a failover also operates as a DNS server. Anyone know the simplest way to complete this? One idea I had (that seemed like a bit of manual work): Create script that runs every 60 secs through CRON on firewall (running pfsense) and have it check if master-server is up. If it's not, it will send a WOL signal to the slave, which has a mirrored image of the first. the problem I have with that is I will also need to create a script to keep both synced properly which seems almost impossible if one is shut down until failover (my thought was periodic rsyncs.) Perhaps creating a FS to direct all files to for the master/slave would be the only way around that.

May 19, 2011I am trying to install a Red Hat cluster on my servers. In order to configure an heart bit between the servers I must give a valid multicast address. I wanted to know if there is a way to validate a multicast address before using it. For example if it is already in use i don't want to use it.
I read a little about it and there is a Perl module called IO::Socket::Multicast: [URL] There is a tool called mcasttrest.pl: [URL] Oracle use it to test multicast. But I am not sure what will do the trick in Red Hat cluster.

Fedora Servers :: Put Together A Sort Of Home "cluster" System?
Mar 5, 2011I was wondering if and how it would be possible to put together a sort of Home "cluster" system. pecifically, I wanted to make it so I would have a central server and a few computers, where the central server holds the home folders and settings of each user, and each user can log in to any of the computers using a standardized login (into the server), where anyone could log in with their account on any of the few computers - and their home folder (Desktop, Documents, Music, etc) would automatically be there.
Also if possible, would there be some way to centralize the applications that show up on each "client"?

Feb 12, 2010I've looked all over the web, but don't see an answer to my particular case. I'm in GParted in Ubuntu Live CD 9.10 amdx64 To prep for Ubuntu install, I'm attempting to resize and re-partition my second hard drive which was FORMERLY my primary boot drive for Vista before it crashed a few days back. It is CURRENTLY my Vista User data file and is about 250Gb in size. The drive is a SATA 500Gb total.
But GParted now all of a sudden gives me several "Cluster accounting failed at blah blah: missing cluster in $Bitmap" error messages. Is there a good way to 'fix' these errors? (besides reformatting it) I deleted the long-winded background, so let me know if you need more info. Short version: I installed vista by reformatting my 120Gb data drive as the primary master now. Then I plugged in my 'previous' 500Gb Sata drive, and pointed Window's User folder to my old User folder, and voila, was back up and running in Vista... minus all my programs. but now, both drives are recognized by GParted as "boot" drives.

View 1 Replies View RelatedUbuntu :: Cssh Not Reading Cluster Tags From .csshrc File?
Feb 8, 2010When using cssh, I define some cluster tags in my local .csshrc file. Other parameters seem to be picked up by cssh, but the tags are not.I have no /etc/clusters or /etc/csshrc files. I create a fresh, default .csshrc file and append a line like:myhost = frodoWhen executing "cssh myhost", I get: Can't call method "name" on an undefined value at /usr/bin/cssh line 988This is the same message I get if I make up some destination, like: "cssh doesnotexist". So it looks like rather than picking up the tag "myhost" from .csshrc, and translating the command to "cssh frodo", it does a dns lookup on myhost.I've tried making a /etc/csshrc file like this (but without the equal sign), but that doesn't work either. This is all on Ubuntu 9.10 with cssh version 273.
