Server :: High-Availability HTTP Load Balancer With HAProxy & Heartbeat On RHEL 5.4

Oct 15, 2010

I am trying to setup a High-Availability HTTP Load Balancer With HAProxy & Heartbeat using the below links.

I have all RHEL 5.4 servers hosted on VMWare.

[url]
[url]

This is the scenario, as given in the links as wells as my setup.

Load Balancer 1

Load Balancer 2

Web Server 1

Web Server 2

I have followed all the steps mentioned in the links religiously except the 2.2 here, in which it is asking to configure the vhosts. I could not really understand , what is to be placed in /etc/httpd/conf.d/vhosts.conf file and in which Web Server.

Due to this step only, I think I am failing in Failover test given in Point 4.1 here. I am able to open the webpage by [url] which gives the content of Web Server 1 (http1.example.com). But, when I try to shutdown the http service (to check failover), it does not shows the contents of Web Server 2 (http2.example.com)

Although, I am able to succeed in Failover Test 4.2, in which shared IP 192.168.0.120 switches when I try to start/stop the any of the Load Balancers.

Networking :: Load Balancer With Direct Routing - LVS-DIR

Jul 16, 2010

I am working on a load balancing project. The type of routing I am implementing is direct routing (LVS-DIR).

The following is a script that sets up the Linux Virtual Server (LVS) or the load balancer:

On both, the LVS and Real Server 1, the firewalls (iptables) are not running.

A few questions I have are:
1) On the LVS, is apache supposed to be running?
2) If so, what would be the ServerName for apache on the LVS?
3) What would be the ServerName for apache on the real server1, is it the server real IP or the VIP?

When I try to access the web content on real server1 in a browser on the LVS, I get Failed to Connect. A connection to the server cannot be established.

The load balancer has two NICS, eth0 and eth1. The real servers will connect to the load balancer via eth1, and the client will connect via eth0.

Server :: Setup Master / Master Mysql In HA Setup Without Use Of Load Balancer Provided By Host?

Mar 31, 2010

I have a load balancer with 2 web servers behind it. The web servers rsync with cloud storage to update their apache directories 1 time every hour. Apache is just running php pages that pull/push data to a DB so they dont need to be updated that often. However I need to figure out how to implement a Master/Master MySQL setup to have my web servers point to for the PHP stuff. I need to implement it without having a single point of failure. The Load balancers are useless for failover as they only detect availability based on Ping request. So putting a master/master setup behind a Load Balancer is out. what is the best way to setup the master/master mysql in a HA setup without the use of a load balancer provided by the host?

Networking :: Load Balancer - Ssh Sessions From A Single Head Node To Multiple Slave Nodes ?

Apr 7, 2010

My requirement is to route ssh sessions from a single head node to multiple slave nodes. So what i want is, for a client there is just one point of entry (master/head node) to ssh into, it evaluates the load on the slave nodes connected on to internal network and routes the ssh session, kind of a ssh load balancer. Do you have any idea what open source solution i can apply for my problem?

I have tried using LVS piranha, it works well for http and https load balancing but not for ssh load balancing.

Server :: Beowulf Cluster With Xen On IBM Bladecenter For Private Virtual Machine Farm

Feb 16, 2009

I'm probably dreaming, but I have a hobby project in mind that I would like feed I have an opportunity to purchase a 3 year old fully populated (14 x 3Ghz dual Xeon nodes) IBM bladecenter relatively inexpensively.I thought it would be fun to set it up as a beowulf cluster with open source xen and test the market to see what people would pay for Private virtual machines.

My thoughts are to use 64 bit Centos 5 as a base to get the beowulf cluster up and then load xen.I haven't really looked at the market but I figure I should be able to run 50 private virtual machines charging say $50 per month. I figure I can use rsync to backup the virtual machines to a different location. I plan to connect to linux based Network Storage running 3 x sata 1TB drives, probably via iSCSI. Along with the drive capacity currently on the blades I should get 2-3Tb online capacity over a Gbit network. (Cisco 14 + 4 network switch module)

I realise I have a bit of setup work to do and before I go investing a lot of time and a little money I'd appreciate some pragmatic advice as to why this may be a stupid venture.

Hardware :: Managing Mount Points For External Drive "farm"?

Sep 25, 2010

I have inherited a large number of external drives. Some are mechanical drives. Others are flash. Most are USB. Some are Secure Digital (SD) or Compact Flash (CF) or similar "media" cards. Currently, on connection, everything gets mounted automatically into a folder that is part of /media. If the drive has a "label", the mount point is /media/driveLabel. I don't want to guess or search for where this stuff gets mounted and so I'd like to "manage" all of this somehow. Q1: Are there any end-user, desktop tools to help manage a large pool of external drives?

I know that udev rules operate to accomplish the drive device creation, configuration and mounting in a automatic way. Q2: Are there any utilities that make it easy to administer where to mount drives, what to do when each drive gets mounted, how and when to notify the end user? and so on.

Fedora Networking :: How To Configure For Load Balancing

May 2, 2011

I have 3 machine each one is running ftp daemon(example), and have an application daemon which is monitoring load and can communicate with remaining servers. now for every new connection I can check load of each server and I want to redirect that socket connect request to least loaded server. that load balancer daemon should be able to do this at runtime without breaking any existing communication. This should work seamlessly with any application. How I can achieve it using any combination of Advance routing, VLAN, iptables LINUX.
