Failover/Loadbalance

RT Users

Hi All

I am looking for a solution of RT3.2.2 with Mysql 4.0.13 (or higher that
RT recommends) under Solaris 8 to setup as Loadbalance/failover/cluster through the WAN.
I know mysql 4.1.x supports clustering. Not sure if Apache does anything
like that or not. But just to stick with RT’s recommendation I think
mysql 4.1 is not recommended yet.

Has anyone done any setup similar to this?

Any feedback is appreciated.

Thanks

FYI MySQL 4.1.x ‘clustering’ is VERY limited and VERY early stage. It is
an ndb based memory only system so doesn’t ‘scale’ for large datasets.

Mysql’s clustering probably wouldn’t be much good for RT, last I heard
their clustering solution required your entire dataset to be loaded into
RAM, so unless you have a very small database (or A LOT of RAM) this
probably wont work.

Mysql also offers replication, using a single master and many slaves, I
believe this would however require a bit of work in RT3, as it would
need separate database handles for reads and writes I believe.
