Bootstrapping Galera Cluster the new way
A while ago it was pretty inconvenient to start a complete Galera Cluster from scratch. Rolling restart an such things are already working well but bootstrapping was a pain.
With Galera v2.2 new functionality came in. We tried it out and it did not work as documented. :-( Thanks to Teemu's help we found there was a documentation bug in the Galera documentation.
The settings which were working for us are:
wsrep_cluster_address = "gcomm://192.168.1.2,192.168.1.3?pc.wait_prim=no"
And when all 3 nodes of the Galera Cluster are started and ready to join you can run:
SET GLOBAL wsrep_provider_options="pc.bootstrap=1";
I hope we can go life on Thursday with the new Telco VoIP Cluster for 2500 employees...
Have fun and enjoy an even better Galera Cluster for MySQL!
