LVS and RT

RT Users

Hello,

We have been playing with different redundant architectures.

The system we are trying now is comprised of:
1- Two front end servers running an LVS based proxy system. Proxy to
RT and also other apps.
2- The two previous servers load balance to two RT servers.
3- The RT servers talk to a MySQL Master/Slave setup.

We are trying to understand how Mason/Perl/RT are managing end user
sessions. We are getting session mix-ups. User A becomes User B…

Any experience with such a setup? Or any enlightenment on how user
sessions work in RT?

Thanks
Thierry

Are you storing your sessions in the database with an INNODB table,
or are they stored in the filesystem?

I would say you need to add some persistence on your lvs side. We do this with something else and keep persistence for a while (like 4 hours, more than normal), this way its balanced to a degree, users within a certain time frame are returned to the same server. When dealing with web sessions you are probably going to have to do this.-----Original Message-----
