I'm building a LAMP stack with Puppet, so far it's been great for doing the 'roads and sewers' standard build bits.
I'm a bit unsure how to use it to manage e.g. the MySQL active-passive pair we plan to use, though. Need a bit of guidance from veterans I think. It's not HAed, we just want a spare DB node I can point the php apps at while patching the primary. If I was to apply a 'master' class to one node and a 'slave' to the other, how would failover be managed? Is that something outside Puppets reach, or would you switch the roles in manifests, or turn off Puppet while things fail over, or something else? There's a similar issue with NFS docroots; I have 2 NFS backend servers that I can see from my webservers, and it's easy to tell puppet to manage the mount. But I'm not sure whether I should be switching the mounts via Puppet manifests, or another mechanism. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
