MySQL GA clustering
Good day all I would just like to confirm the following please. I have a client who is running the free downloadable version of MySQL and they would like to go the clustering route for quite a couple of reasons. Does anybody know whether clustering is available with the downloadable version or is this only available with Enterprise? They would also like to know what they need for proper clustering in terms of disks (shared storage or local) memory (i found this on a website though) etc... and resouces they can look at on how to implement. I don't know clustering on MySQL at all so I will really appreciate some help on this. Regards Machiel

Apparently OpenMosix won't work with MySQL because MySQL uses Shared Memory. There is apparently a component called MAASK which might help.

Re: MySQL Web Clustering...
Go for a simple MySQL master - slave configuration. I'm runing 1 master 3 slaves for performance issues and doesn't have any problem at all for 1 year.. Of course in this case you should change some code in your webservers to direct SELECT queries to slave machine to gain performance on the master. I will also keep in touch with MySQL Cluster development and probably go for this in the near future.

Re: MySQL Web Clustering...
I currently run LVS (pre-distribution) on my farm, which gets about 100M hits/month. Good points about LVS are that it is completely rock solid, and runs on minimal hardware. I have never run MySQL behind it, as I think that would be a bit flaky for a live site. Probably worth checking out though. I would think that instead of LVS Load Balancing, server failover might be a more viable path for MySQL.

Re: MySQL Web Clustering...
Unless you have a specific need for it, you could save yourself a lot of trouble by putting select tables or databases or even clients on each server. This also means you don't incur the added overhead of keeping the database in sync, creating actions if a master goes down, etc. Then just tell client1 to use database5 as their hostname for example. Replication requires that updates go to the master, which requires client-side code, or an intermediate daemon which analyzes the statement and forwards the request. -Mike From: Peter J Milanese [EMAIL PROTECTED] To: Roy Nasser [EMAIL PROTECTED] CC: [EMAIL PROTECTED] Subject: Re: MySQL Web Clustering...

Re: MySQL Web Clustering...
The meaning of that was client-side being sending inserts/updates to the master server. This would be done in the program/script upon an insert query. A daemon could forward insert/update requests to a master and all others round-robin and simply pass packets. This is if you have to make it seamless. Would require some work to make one though. -Mike From: Jeff Smelser [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: MySQL Web Clustering...

Jeremy Thanks for the reply Jeremy. What i need to build are a mysql master server with two nodes both active at the same time. Don't know how this is called in english but we call it an HA active-to-active; while standard HA clustering is considered active-to-passive because only one node at time is working while the other one it will come up only if the first one is falling. I'm not a DBA and i know very little on setting up DB servers, but for what i have understand from the online documentation, if i use a slave server with db replication, when the master fails, the slave can only manage queries and not commits; I've also read that db replication fo the master servers will be supported starting at v.5.0 of mysql. Now, how i can achieve the active-to-active task? I've tought to put up two nodes with a shared disk-array where the db stands, and to share the processes between the two nodes using openmosix. What do you (and the others) think about that? Any advice is really welcome! :) Thanks in advance for any reply!

mysql and clustering
Hello to all, I'm requested to build an HA cluster for a mysql master server which is running on a redhat 8.0 box . Does anyone have done this before? I've though to use lvs or openmosix as clustering software. I'm interested on which clustering software you may have used, and to have a feedback of problems you may have encontered. Thanks!
