Hi!
Ok, Apache balancing requests. Another option is LVS without Apache
nither mod_load_balancer / mod_proxy_balancer. the problem: the user
with session is going always to the same backend web server. This is not
real balancing for me.
It would do that only if you tell Apache to support sticky sessions.
But actually this is a standard practice to direct all request for the
same session to the same serfver.
The major problem is do real balancing between servers and keeping user
session alive. I'm wondering if could be done with DRBD (shared disk) as
you say. Thre are two way to store sessions, on DB or Disk. Sessions on
DB is trivial, no problem. Sessions on disk, if are shared with DRBD
then maybe the question is solved?
Yes if you do want to do that kingf of load balancing.
Is for a shared hosting and users choose the way they develop. We
couldn't say users to store sessions on DB or Disk
As I said the standard practice is to use sticky sessions and have
shared storage with presistent sessions for failover case if one node
dies.
thanks, Cheers!
