Hi, Heartbeat can give you solutions for that.. The only real problem is indeed the storage which you want to be synchronized. High Availability clusters should provide a way for having shared storage (i.e. scsi disk / JBOD connected to two servers), while the main node is down, the other will mount the disk.
(Note that there's a big risk if two nodes mount the same storage. The cluster should be connected with at least two internal cables so it could monitor each node even when main network is down) Anyway you'd better read some in www.linux-ha.org . Also note that RedHat has its own HA cluster solution (pirhana I think) which comes with their RH Advanced Server, which I have no experience with. - Oren On Thu, 2003-09-25 at 02:42, Sagi Bashari wrote: > Hello > > We are running a website that is written in PHP and is using a MySQL > database.
