  • In this post I’m going to take a look at a two-node CentOS 7 Apache active/passive cluster using mostly packages in the Red Hat cluster suite.  In case you don’t already know, CentOS is created by making use of the source packages provided by Red Hat Enterprise Linux (RHEL). 

  • In my last post, I went through the steps to build an active/passive Apache web hosting cluster on CentOS 7.  Building on the same platform, I’m going to add replicated block storage to our cluster by utilizing DRBD

  • If you have been following along, in my last two posts we successfully set up an active/passive Apache cluster on CentOS 7 and then we added shared storage. The storage I chose was local storage. In this post, I'll be replacing that with iSCSI shared storage and adding MySQL (actually MariaDB).
