Hi, I have a working 2 node HA setup running on CentOS 6.5 with a very simple Apache webserver with replicated index.html using DRBD 8.4. The setup is configured based on the "Clusters from Scratch" Edition 5 with Fedora 13.
I now with to replace Apache with a MySQL database, or just simply add it. How can I do so? I'm guessing the following: 1 . Add MySQL service to the cluster with a "crm configure primitive" command. I'm not sure what the params should be though, e.g. the configfile. 2. Set the same colocation/order rules. 3. Create/initialize a separate DRBD partition for MySQL (or can I reuse the same partition as Apache assuming I'll never exceed its capacity?) 4. Copy the database/table into the mounted DRBD partition. 5. Configure the cluster for DRBD as per Chapter 7.4 of the guide. Is this correct? Step by step instructions would be appreciated, I have some experience in RHEL/CentOS but not in HA nor MySQL. Thanks! -- - Goi Sihan gois...@gmail.com
