I've never used ldirectord; I wrote some of my own utilities and rewrote a
bit of mon so that both will read from real simple (seven lines maybe) ifcfg
files in the /etc/sysconfig/network-scripts directory in RH. (like
ifcfg-ipvslvs0 sorta stuff)
BUT... I was wondering...
You see -- a big reason why I don't use things like ldirectord is because I
load balance 1024+ virtual servers (which are mainly web virtual hosts) onto
four identical real servers. Most programs like ldirectord would require me
to setup 1024 entries in some configuration file in order for me to do what
I need done.
The way I've setup my system is allowed mon (and the other scripts which
setup the ipvs for me) to respond to subnets. That is, I can say that my
virtual server is 216.69.196.0/22 which should be balanced onto servers A,
B, C, and D. Then alerts inside mon as well as ifup/ifdown files which
recognize this automatically bring the whole subnet up or down balanced onto
those four servers that I also put in that same configuration file.
Basically I'm asking if ldirectord (or any other package) supports this sort
of mechanism... The ability to load balance a subnet rather than just one
signel virtual server.
I apologize if ldirectord does have this ability and my laziness to not read
any of its documentation has left me in the dark, but I'm guessing it does
not.
This was also one of my biggest complaints with all of the commercial load
balancers I've used (LocalDirector, BIG/ip, etc.) -- in order to what I'd
need to do, I'd have to do a whole lot of configuration by hand (or MAYBE by
some script). The LocalDirector wouldn't even allow me to do it on its
console. Because of memory constraints, I would only be able to tftp such a
huge configuration onto it.
Anyway -- I'm just curious.
All the best --
