I am new to Heartbeat all over a couple days.
Goal: Two Squid cache servers running in failover mode. When the squid
process dies on one server, failover to the other.
OS: RHEL5
Squid: 2.6Stable18
Heartbeat: 2.1.3 compiled from source
Server #1
Name: Squid1
eth0 = IP address on the local LAN, this is the IP that people should
use for squid, lets say 10.95.1.1 (this should be the same IP as the
failover, yes?)
eth1 = interface for heartbeats to the failover. This is using a x-over
cable to the eth1 on the other server. 192.168.1.1 /24
Server #2
Name: Squid2
eth0 = IP address on the local LAN, this is the IP that people should
use for squid, lets say 10.95.1.1 (this should be the same IP as the
failover, yes?)
eth1 = interface for heartbeats to the failover. This is using a x-over
cable to the eth1 on the other server. 192.168.1.2 /24
Both servers can ping each other over the xover
I currently have heartbeat fully running as per Alan's first "Installing
Heartbeat" screencast
ha.cf
use_logd yes
bcast eth1
node squid1 squid2
crm on
My haresources is blank for now , until i know how to do what I need.
crm_mon says:
============
Last updated: Fri Apr 18 14:50:58 2008
Current DC: squid1 (1691d699-2a81-4545-8242-b00862431514)
2 Nodes configured.
0 Resources configured.
============
Node: squid1 (1691d699-2a81-4545-8242-b00862431514): online
Node: squid2 (2422b230-22f2-451b-aa95-0b783eccab8d): online
If i start and stop heartbeat randomly on the servers crm_mon changes as
it should.
I have squid running on both servers.....How do I configure (based on my
info above) heartbeat to listen on each server and when squid process
stops to failover. Also, dont the IP's that my clients have to access
the squid server need to be the same on both servers? Any help would be
huge!
Thanks,
Nick
