Hello list, I am planing to design high-available mysql servers which serve as one single virtual mysql server to application servers. My criteria is:
1. HA(High Availability) Due to mission critical services, we hope the mysql clusters can provide high availability to application servers. In the hardware term, I think hardware raid or software raid is necessary, but which is recommended in mission critical case? In the application/software term, I hope to have load-balancing among mysql servers. Also, I'd like to have fail-over design in it. 2. replication Now we know there's one-way replication in mysql-3.23(ok, maybe two-way replica. is also possible), how reliable is the built-in replication function in mysql-3.23? Can I rely on hardware syncronization solutions like storage appliance solutions? The service based on it(mysql) is not quite mission critical, but we just do not want to lose the high availability. I ask here just want to know how possible can I build a high-available mysql clusters with considerable scalebility. Any ideas are hightly welcome. -- Patrick Hsieh <[EMAIL PROTECTED]> GPG public key http://pahud.net/pubkeys/pahudatpahud.gpg -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
