Hi,
With Pacemaker 1.0.4 and Heartbeat 2.99, I need to create a
configuration which does the following (for example with 2 nodes):
* apache running on every nodes
* nginx running on every nodes
* an IP address running on one node only
This scheme is easy to produce (one clone for apache, one for nginx, a
standalone resource for the IP).
Now that's where the things get interesting, I want to relocate the IP
address on another node _if_ nginx fails on the node on which the IP runs.
That's where I'm completely lost. I think I should add a colocation
rule, but I fail to see which one. I've read the Colocation explained
documentation and the other documentations, but it's still unclear how
to model the colocation.
The simplest thing I could think about would be to make a group of IP
nginx, but in this case nginx doesn't run on every nodes.
Can someone help me?
Thanks!
