Replication using DRBD
In this recipe, we are going to cover block level replication using DRBD for Postgresql.
Getting ready
A working Linux machine is required for this setup. This setup requires network interfaces and the cLusterIP. These steps are carried out in a CentOS version 6 machine. Having covered the PostgreSQL setup in previous chapters, it is assumed that the necessary packages and prerequisites are already installed.
We will be using the following setup in our hierarchy:
Node1.author.org
uses the LAN IP address10.0.0.181
and uses172.16.0.1
for crossoverNode2.author.org
uses the LAN IP address10.0.0.182
and uses the IP address172.16.0.2
for crossoverdbip.author.org
uses the cluster IP address10.0.0.180
