sentora cluster

[Me.B]

Been thinking a while over sentora cluster. It was amazing challenge and idea.

A lot of issues but I think got the solution:

1. master node with full sentora install.

2. /var need to be on glusterfs (hmm logs) or maybe be only /var/sentora/hostdata

3. db on mariadb Galera or mysql. upgrade the main db to cluster.

4. install sentora stack on slave and upgrade db to cluster mode and same glusterfs setup to replicate data.

We may need too a small script on slave for apache conf rebuild or symlink it /var/sentora. same over dns data if needed.

sessions will be replicated. and all users data/bd's.

We could that way cluster web and email services.

Cluster could share load and survive disk failor but would be down if config messed up or hack.

I need to test this soon.
