Hi Heiko,
yes, that does it! (you need to add the flag to the libipvs/Makefile,
too).
Another thing that is 'new' in that context:
we needed to
export PERL_LWP_SSL_VERIFY_HOSTNAME=0
somewhere, otherwise SSLeay complains about certificate verification
errors. I'm not sure if there is a way to avoid this kind of mismatch
when you use ldirectord to redirect https to a battery of backends.
Anyway, we put the environment variable in ldirectord's init.d script. I
don't know if that should be there by default, or how to make this bit
of trivia known to fellow users...
I'll submit my modifications to save-config later on, along with a bunch
of other trivial mods (we implemented the status option to some init.d
script (named, openvpn, ldirectord, httpd, nrpe, firewall and xntpd) as
we have built a really cool heartbeat2 cluster :-)
Don't expect this before a few weeks though, as I'm pursuing a different
mission now (vacation ;-))
Thanks and all the best,
Frank
