Networking :: Clustering RHEL 5.2 Server?
Mar 2, 2010My current project environment setup is having a single server, running on RHEL 5.2, that is constantly receiving incoming data (video and text) over a periodic interval e.g. every 30 minutes. Initial in-house testing projected the server will be generally busy, so we decided to incorporate a second server for load balancing purposes. So now, server A and B will need to be clustered. Once that is done, incoming data will balance out between the two server (or at least that is what I will like to achieve. Note, I'm aware that at the switch side, I'll need to do some additional configuration and that part is covered).
I've been reading on Red Hat Cluster Suite and the Linux Virtual Server (LVS) seems the way to go. However, I noted that the LVS solution require at least a two-tier solution, and that would incur 3 additional servers instead of just 1. So here's my questions:- I looked around and probably know the answer, but I'm gonna ask anyway. Is there a one-tier solution for LVS i.e. have anyone tried or whether it's even feasible. From my reading, it don't seem so but just want another opinion. Is there any other way for me to do the clustering (for load-balancing) without LVS?
Sidenote: I'm currently looking at Ultra Monkey and will be trying out in a while. However, the project I'm doing would be rolled out to live site eventually, and my customer is kind of....particular. I'm just wondering if there's a software/application (that need to be purchased) and comes with support.
Server :: Figure Out Ho To Setup EC2 Clustering?
Mar 16, 2010I am trying to figure out ho to setup EC2 clustering. I am seeing heartbeat as an option. I need something that will monitor the state of a daemon, and not if a daemon is running. For example, say I want httpd to be high availability. Does heartbeat monitor if httpd is not in a hung state, or does it simply do a ps -e |grep httpd? So my question is, how does heartbeat work?

Mar 14, 2011I added the "@clustering" and "@kvm" keywords to my ks.cfg file but during installation, an error about not being able to find either of these packages popped up and it wasn't installed.
I do see the Cluster and VT directories in my redhat_es5.4 directory along with the Server directory. The rest of the files install just fine.
In doing some net and forum searching, I find a reference to a base.repo file that lists the directories but I'm not sure if it's related to creating a yum repository or if not, should it have been created in the redhat_es5.4 directory.
While I've built kickstarts for several years and am comfortable with the file, this is the first time I'm working with rpms outside the main Server path.

CentOS 5 Server :: Web Server Clustering With Centos5.2
Mar 22, 2009To clustering my web server so that it becomes Highly available. Its currently running php, apache and mysql with no redundancy in place. I want to be clustered so that if one node goes down then the second one will automatically take over. I have done that with HA in RHEL but I want to use centos clustering solution for this. Also how willl they share the web contents and mysql database among two nodes I have no idea. I have managed a iscsi target to store contents but it doesn't work as expected.
View 1 Replies View RelatedServer :: Clustering Mail Servers (CentOS/Amazon EC2)?
Feb 23, 2011I'm looking to set up a clustered mail server, I kind-of know how I'm going to do it but wanted to check if there was a better way. So we have 3 mail servers, running as EC2 instances on Amazon AWS. We were going to achieve clustering by giving all three a shared EBS storage device to store the mail. The mail would be received by any of the three servers (Via postfix) and could be retrieved from any of the three servers (via dovecot). For receiving mail (SMTP), the domains would have 3 MX records pointing to each of the servers but for sending and retrieving mail (SMTP and POP3/IMAP) the three servers would have one DNS A record with 3 IPs associated (I know when using this method for web-servers, the load gets distributed among the IPs under that record but I'm not sure if this will work for SMTP/POP3/IMAP).
What we want is to have 3 servers that share the load equaly but are completely redundant for all services (POP3, IMAP and SMTP). We also need to be able to scale upwards so if we need to add more servers we can do easily. Also the servers must be perfectly synchronized at all times.

Jun 16, 2011I'm trying to get an HTPC going, but I don't have any money to purchase a new computer. I have 2 desktops in my possession that I am trying to use: 1 is a 2.4 GHz with a 128 MB Radeon 9800 PRO video card (I think) and 1.5 GB RAM (the system is about 8 years old, but I built it top of the line for back then). The second system is a 3.2 GHz dual core with on board video and 2 GB RAM.The problem is, neither system will run 1080p video's without dropping hundreds of packets producing very choppy audio/video. I was wondering if it is possible to cluster these two systems together to harness both their processing power to run 1080p video? I would just jump in and attempt it, but as I have been reading, it looks like processes aren't actually shared across PC's, but auto determined which PC it will run on based on load, which is an issue since neither can cleanly run the 1080p video.

View 1 Replies View RelatedGeneral :: HA / LB Clustering With Specific Software Requirements?
Jun 16, 2010I am looking to build up a HA/LB linux cluster with specific software requirements. For hardware, I have a number of dual xeon PE 2650s and would like to use them as efficiently as possible. These are 32bit systems, I anticipate scaling up to 64bit systems when I have a tested, working solution in place. For distro, I am familiar with CentOs, Gentoo and Ubuntu but unsure as to which would be the best foundation, although leaning towards CentOs. For software, I need to realise all the services provided by xampp (Apache, MySql, PHP, Perl, FTP), plus Red5 flash media server.
My current train of thought is;
6 physical servers; 2 Directors/Heartbeat, 2 Apache, 2 Red5
Gigabit private network for connecting the nodes.
CentOs 5.5 on all nodes.
DRDB across the 2 Apache nodes for Apache, MySql, PHP.
DRDB across the 2 Red5 nodes for Red5.

Server :: Can Boot RH 5 After P2V
Aug 10, 2010I have P2V a physical Linux to a Virtual machine, but i cannot put this VM to boot
I have 2 partitions with 240Gb
In the VM they are LVMs
If I use a RecoverCD i can see both LVMs in the VolGroup00
But my problem is I cannot put the first to boot, since advanced Linux is not my skills I need I little help
Is what I see in my shell booting with KNOPPIX
>pvs
>/dev/sda2 VolGroup00 lvm2 -a 232Gb
>/dev/sdb1 VolGroup00 lvm2 -a 233Gb
Here I think the sda2 is the boot volume, since KNOPPIX is using sda1
I can mount the VolGroup00/LogVol00 into the /mnt/sda1 and check the files etc, but I need to put this as the boot when the Linux boots
In the sda1 that I mounted I can look the fstab and is like this
/dev/sda2 VolGroup00/LogVol00 / - ext3
LABEL=boot /boot - ext3
devpts /dev/pts - devpts
tmpfs /dev/shm - tmpfs
proc /proc - proc
sysfs /sys - sysfs
