Hello
I have installed pacemaker and corosync on my redhat el5 with the
clusterlabs repository:
http://clusterlabs.org/rpm/epel-5/clusterlabs.repo
The installation worked fine, just needed to install some dependencies but
all ok :)
So now my question. I need the build a high-available web cluster with
loadbalancing,
on my old machines I used heartbeat version 1, ldirectord and ipvsadm,
works great :)
Now I need to replace heartbeat version 1 with corosync+pacemaker (please
don't ask why)
Here more details about my infrastructure
The 2 loadbalancer that I need to configure with pacemaker/corosync
pacemaker1.lenux.local IP: 192.168.33.210 (live)
pacemaker2.lenux.local IP: 192.168.33.211 (stand-by)
virtual IP: 192.168.33.240
3 webserver (are in the same network)
www1.lenux.local IP: 192.168.33.241 (virtual IP: 192.168.33.240)
www2.lenux.local IP: 192.168.33.242 (virtual IP: 192.168.33.240)
www3.lenux.local IP: 192.168.33.243 (virtual IP: 192.168.33.240)
Ok, installed pacemaker and corosync on both loadbalancer..after that I
configure corosync like this (also on both loadbalancer):
aisexec {
user: root
group: root
}
totem {
version: 2
token: 5000
token_retransmits_before_loss_const: 20
join: 1000
consensus: 7500
vsftype: none
max_messages: 20
secauth: off
threads: 0
clear_node_high_bit: yes
interface {
ringnumber: 0
bindnetaddr: 192.168.33.0
mcastaddr: 226.94.1.1
mcastport: 5404
}
}
logging {
fileline: off
to_syslog: no
to_stderr: no
debug: on
timestamp: on
}
service {
# Load the Pacemaker Cluster Resource Manager
name: pacemaker
ver: 0
}
now I need to add the ldirectord (already configured and located in
/etc/ha.d/ldirectord.cf) resource to pacemaker with the crm tool...but I
don't know how? I need to add the virtual IP and the ldirectord service
that can swap to the other loadbalancer on failure. I read the hole wiki
without finding the right answear..I hope someone can help me!
Thanks
Regards
Juan
