So I have a question about heartbeat and ldirectord. This may be a simple question, but I don't know the exact answer so if I could get some help with this it would be greatly appreciated.
I am working on a project that has the following servers:
2 Linux directors each running ldirectord and heartbeat
3 web servers which are being load balanced via the Linux directors
Multiple other servers that the client has running for their business
There are 8 public or “virtual” IPs all used to get to various web pages, servers and services.
We will say the IPs range from 18.104.22.168 to 22.214.171.124 with netmask of 255.255.255.0
Internally they are running a standard 192.168.X.X network.
We are running a High Capacity High Availability and Load Balancing model for the setup using ldirectord and heartbeat. The picture below is a general setup
Anyways now down to the real question.
I am wondering if there is anything special we need to do with the /etc/ha.d/haresources
file to accommodate for all the extra IPs. Or does the /etc/ha.d/ldirectord.cf
file take care of the “virtual” IPs?
This is what the /etc/ha.d/haresources
and the /etc/ha.d/ha.cf
files currently look like.
bcast eth0 # Linux
mcast eth0 126.96.36.199 694 1 0
respawn hacluster /usr/lib/heartbeat/ipfail
apiauth ipfail gid=haclient uid=hacluster
What I am unsure of is if we need to add more IPs to the /etc/ha.d/haresources
file since the client wants to be able to get to all of their servers via a public IP being routed through the linux directors.... PLEASE HELP!
