Hi all,
We in the implementation of heartbeat with squid. we done the script for
starting squid during heartbeat takeover. But when the service (squid in
this case) is stopped, the heartbeat will not takeover. I saw that there
are some resource monitoring solutions are available, but i don't know
how to configure them. I have attached the sample configuration files
for your reference.
Please provide a solution for monitoring the service.
ha.cf file
---------
logfile /var/log/ha-log
logfacility local0
ucast eth0 192.168.1.45
auto_failback on
watchdog /dev/watchdog
node test1.mydomain.com
node test2.mydomain.com
haresources file
----------------
test1.mydomain.com 192.168.1.100 squid
authkeys file
------------
auth 2
2 sha1 HI!
Your help is very thankful,
