HeartBeat

To set up Heartbeat/Clustering two nodes are mandatory. You will also need 2 "Public IPs" and 2 "Internal IPs"

There are 3 configuration files that will need to be created and configured.

- authkeys (encrypted passphrase, This will be identical on both master and slave)
- haresources (defines master, This will be identical on both master and slave)
- ha.cf ( defines master,slave,internal IP,etc, This will be different on each server)

1. Get updates

2. Configure Private IP

- vi /etc/network/interface
- add eth1 with private ip info
- /etc/init.d/networking restart

2. Install Heartbeat

3. Navigate to Heartbeat Directory and create "authkeys"

- vi /etc/heartbeat/authkeys
  - auth 1
  - 1 sha1 yourpassphrasegoeshere
- chmod 600 /etc/heartbeat/authkeys (must not be 'world' readable or else Heartbeat will fail)

4. Navigate to the Heartbeat Directory and create "haresources"

5. Navigate to Heartbeat Directory and create "ha.cf" on the master and edit the following lines

logfacility daemon

keepalive 2

deadtime 15

warntime 5

initdead 120

udpport 694

ucast eth1 ##This is where your Slave Private IP goes##

auto_failback on

node master ##Hostname of Master##

node slave ##Hostname of Slave##

respawn hacluster /usr/lib/heartbeat/ipfail

use_logd yes

6. Restart heartbeat

7. Navigate to Heartbeat Directory and create "ha.cf" on the slave and edit the following lines
