Assuming you have 2 NICs, one should be configured for your "normal" network and the other as a private network between your clustered nodes (via the crossover cable). Now, let's open a terminal and use curl to access the Floating IP on a 1 second loop. The preferred host is the node that should run the associated service(s) if the node is available. The master holds all the resources until a failover, at which time the slave takes over. http://sauvblog.com/cannot-open/cannot-open-include-file-delay-c-no-such-file-or-directory.html
Getting Started The first thing you'll need is two computers. You'll then learn how to avoid performance degradation and any risk of the sudden disappearance of a service on a server. We'll use vi:

If you don't have a domain name right now, you should use the Floating IP address instead. http://marc.info/?l=linux-ha-dev&m=101429780411627&w=2 The watchdog function provides a way to have a system that is still minimally functioning, but not providing a heartbeat, reboot itself after a minute of being sick.

Note: This tutorial only covers setting up active/passive high availability at the gateway level. http://sauvblog.com/cannot-open/cannot-open-transaction-log-file-no-such-file-or-directory.html Note: This file must be the same on both nodes! If you want to extend your Heartbeat setup, the next step is to replace the example Nginx setup with a reverse-proxy load balancer. For ring topologies, number of hops allowed in addition to the number of nodes in the cluster.
If you try andstart it as non-root then this will happen. If you do that, you'll have services running on both nodes and when you re-connect the heartbeat, a bit of chaos.... CentOS 5.x uses "el5" in rpm package names, just like RHEL 5.x. http://sauvblog.com/cannot-open/cannot-open-include-file-cmath-no-such-file-or-directory.html Next, type "cat /proc/misc | grep watchdog" and note that number (should be 130).
Check /usr/src/linux/.config for "CONFIG_IP_ALIAS=y" if you don't have it, you'll have the line "CONFIG_IP_ALIAS is not set". The "work" I am contributing is mostly compiling bits and pieces from other HA documents (such as Volker Wiegand's Hardware Installation Guide) into a document that can help novices get started If this all works, you've got availability.

Create authkeys File The authorization key is used to allow cluster members to join a cluster. The example node names are "primary" and "secondary", which matches what we named the Droplets. In addition to guides like this one, we provide simple cloud infrastructure for developers. Once your hardware is in order, you must install your OS and configure your networking (I used Red Hat).
