Clustering without external storage
I want to have MySQL database on two Linux servers (RHEL AS-4.
Can I have cluster of these two servers without using shared storage? I have 2*300 GB SCSI hard drive with RAID1 on each server. I want to have failover between these two servers. Please suggest. Thanks, Ajatiti |
You could do a master/slave relationship. I know you can set it up in php to failover to the slave if no response comes from the main database.
Essentially the slave database pulls queries from the main database to get its updates. Not ideal but should work in your case. |
What about using MySQL cluster?
It doesn't require external storage but it requires one server each for MySQL node, Data node and management node. Is it possible to have MySQL node, data node and management node on the same server with Linux? Then have backup server with MySQL, data node and management node on same server. So in this case we can have only two physical servers and no external storage. Is this possible? Thanks, Ajay |
