In the interest of starting some sysadmin discussion, I'm looking for
some help on setting up a load balancer.
I'm trying to get ldirector setup to load balance four bricks. I
think I'm trying to do something a bit unusual in that I'm only using
one load balancer. I'm not using heartbeat, but the man page for
ldirector says 'ldirectord typically is started from heartbeat but can
also be run from the command line'. I can start it, but I'm not
getting redirected to my apache brick heads.
Does anyone have any good resources on setting up ldirector? Has
anyone set it up on only one load balancer?
Not with Evergreen, but yes, I've used a single LVS host. I don't have
a specific resource, and some quick Googling didn't turn up what I
remember using when I got started.
From your notes, the ipvsadm output displayed suggests that the Apache
hosts are listening, at least on their local addresses.
When you say you're not getting redirected. Have you verified that with
something like: tcpdump port 80
Have you verified that they are also listening for traffic on the
virtual address? (172.29.120.84:80 or *:80)
If the tcpdump doesn't see any traffic arriving, then it's likely a
problem with the ldirectord host. If it is, then you've likely got an
Apache, or network issue on the web servers.
