A High-Availability Load Balancer With HAProxy/Heartbeat on RHEL 5.4

[vikas027]

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.

http://www.howtoforge.com/high-avail...rtbeat-fedora8
http://www.howtoforge.com/high-avail...eat-fedora8-p2

This is the scenario, as given in the links as wells as my setup.
Shared IP: 192.168.0.120

Load Balancer 1
Hostname: lb1.example.com
IP: 192.168.0.110

Load Balancer 2
Hostname: lb2.example.com
IP: 192.168.0.111

Web Server 1
Hostname: http1.example.com
IP: 192.168.0.112

Web Server 2
Hostname: http2.example.com
IP: 192.168.0.113

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 http://192.168.0.120/ 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.

Waiting for your precious answers. Thanks in advance.

Hello People,

I have solved it.

I had mistakenly used 192.168.0.112 IP in /etc/httpd/conf/httpd.conf of Web Server 2 (http2.example.com). I should have used 192.168.0.113.
