Is Setting Up A Linux Cluster Difficult?

Hy,
I am new to linuxquestion.org, however i am mid-level linux administrator.

As per my scenario, I want to cluster python and java services in two nodes running RHEL 6.4. Till now by watching tutorial I have seen application level clustering of linux for eg: webserver, mysql database and so on. However I haven't found any with python & java clustering.
I am already familiar with windows clustering having clustered ip of the two nodes. In my scenario, we have both the options open either going with active-active or active-passive cluster. So I want to some sort of idea to achieve linux os clustering and hence obtained clustered ip.
Further any idea on how this service will float from one node to another. Further, I cannot get to the fencing mechanism in Linux. Any idea for this will be helpful to understand.

Hope to get positive respond ASAP. Thanks in advance for those who help me with this.

how can i add k-means algorithm on zrp protocol ?????? in ns2?
I want to add k-means clustering alg. for ZRP protocol to make it run with the inter-zone routing protocol for inter clustering and with intra-zone for intra clustering. note that i am using ns-2.35/ubuntu10.04 and the ZRP was completely added to the simulator

can anyone please send me the clustering code of nodes in ns2?? THank you in advance

hello can i get source code of multi hop clustering for wsn in ns2

Hi,
I work in a company where job security isnt too great at the moment, so I'd like to learn new things, the main one being Linux.

Talking to a tech guy at work he says the best bet to replicate an office environment would be Red Hat, so I would like to install Red Hat Linux Enterprise V7 but am finding it difficult to find an open source website offering a free download for it.
Does anyone have a particular website they get their Linux from at all please?

Also, excuse this very ignorant question, but I'd like to set up a server within my Vmware Workstation 10 environment, plus 3 desktops - would that need Linux Red Hat server plus Linus Red Hat desktop software?

If the above has already been answered then I will happily follow a thread that you could point me too please instead?

Thanks in anticipation,
Clank

Hi!

I am running a script per nohup ./script.sh:
#!/bin/bash
Do.stuff -some_parameters &
Do.stuff -some_parameters

I have 64 cores at my disposal, so i start a script with 60 lines (ignoring 4 cores to be free for allday-jobs). I have to do this for ~800 jobs. A job is done within 20 hours, so each morning i come in, start a script with 60 lines, and come back the other morning.

Today i was thinking...would it be possible to query my jobs? So, whenever a core is free, start the next job from the list given in the script?




I know, i am expected to have already tried things out. But seriously, i cant. This is way beyond my skill level. I am just asking to avoid coming to the lab this weekend

Hello everyone, I am a beginner Linux user. I have a had very little experience with it and would very much like to know more. Eventually I want to have my computer running strictly Linux.

I have experimented with a few distributions but almost all of them have had issues with my current setup. I always have trouble setting up the drivers for my video card and mouse. I have dabbled in Ubuntu(primarily), Fedora and Linux Mint.

My question is which distribution would you all suggest I use based upon my specs.

My System Specs:
CPU: AMD Phenom II X4 925 @ 2.80 Ghz
RAM: 8 GB of DDR3
GPU: AMD Radeon HD 6870 w/ 1GB VRAM
Ethernet: Killer Xeno Pro 2100 & On-Board
Mouse: R.A.T 5

If anything else is needed to help determine the right distro please let me know.

All help is much appreciated.

I am considering on removing all OSX 10.6.8 from my old macbook then installing linux. It is a Mac 2.1 with an Intel Core 2 Duo, 1 processor 2 cores. 1 gig memory. What are your thoughts and or recommendations. The machine is a hardy one and I would love to prolong its life.

Best,
JPN

PS, my goal is to recycle all my old machines. I am old but not dead. I am a real newbie.

hi guys,

i have virtualbox running on centos 7
i want to install another centos7 vm
i googled and found a few sites that show setup
but none show your initial setup in virtualbox
when i want to create a new vm i am offered:
linux 2.2
linux 2.4 (32 bit)
etc etc

all look 32bit...i thought centos7 was 64bit...or is it just emulated?
the only logical choice i can see is either:
red hat (32 bit)
or linux 2.6 / 3.x (32 bit)

i know its only a vm and i can experiment without breaking things (only the vm install) but i have a bit of a time restraint...

Fresh Newbie to Linux. Used to be good at DOS commands. Used Norton Commander a lot. Now have to learn the ins and outs of Linux. Need help with subject. Thanks.
