    Dear All,

    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.


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

    Load Balancer 1
    Hostname: lb1.example.com

    Load Balancer 2
    Hostname: lb2.example.com

    Web Server 1
    Hostname: http1.example.com

    Web Server 2
    Hostname: http2.example.com

    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 :scratch:, 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 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 switches when I try to start/stop the any of the Load Balancers.

    Waiting for your precious answers. Thanks in advance.

    Best Regards,

    Hello People,

    I have solved it.

    I had mistakenly used IP in /etc/httpd/conf/httpd.conf of Web Server 2 (http2.example.com). I should have used
