 Posted: Mon Jul 24, 2006 9:01 pm Post subject: Help with using LVS (heartbeat, ldirectord) please? |
 |
|
I'm using heartbeat with the ldirectord useflag.
Here's the setup. I have 6 mongrel servers (for simplicity sake, I'll refer to them as apache servers).
They will be behind a two node heartbeat loadbalancer. (2 seperate machines purposed to be ha-lb machines)
I've emerged heartbeat, here are my config files.
I actually only have lvs2 running at the moment, and I'll clone it across to lvs1 once I have everything running.
ha.cf (actually, I only include here the uncommented lines, to save space)
| Code: |
logfacility local0
bcast eth1 # Linux
auto_failback on
node lvs1 lvs2
|
haresources
| Code: |
lvs2 192.168.1.94/24/eth0 ldirectord
lvs2 192.168.1.95/24/eth1 ldirectord
|
ldirectord.cf
| Code: |
# Global Directives
checktimeout=3
checkinterval=1
#fallback=192.168.1.82:80
autoreload=yes
#logfile="/var/log/ldirectord.log"
logfile="local0"
#quiescent=yes
# A sample virual with a fallback that will override the gobal setting
virtual = 192.168.1.84:80
# real = 192.168.1.82:80 gate
# real=192.168.1.83 masq 10
# real=192.168.1.85 masq 10
# real=192.168.1.86 masq 10
# real=192.168.1.87 masq 10
real=192.168.1.88 gate
request="status.html"
receive="it works"
scheduler=wlc
persistent=300
protocol=tcp
|
Right now, I'm commenting out the other servers to see if I can just get one return.
Here's what I don't understand, first, are my config files correct?
This machine has 2 nic's, do I need to give the mongel cluster virtual ip to a second nic using ifconfig, or will this happen automatically?
Is IPtables necessary?
I'm completely stuck, let's pretend that I want to start from the very beginning, I have a set of webservers I want to loadbalance, and 2 machines I want to be lvs nodes, where do I go from there?
Many thanks,
Michael

First things first: have you already read the LVS HOW-TO and the part about setting up a new LVS service?
