Corosync and HA-proxy

We will use corosync to create a virtual IP-address which is shared by two systems. One of the systems has the virtual IP-address. If the system goes down, the other system will take over the virtual IP-address. HA-proxy will be running on each of the hosts relaying incoming HTTP-requests to two webservers.

  • 192.168.1.47 virtual IP-address
  • 192.168.1.48 haproxy01
  • 192.168.1.49 haproxy02

Software

        mcastaddr: 239.192.1.1
}
