I have established a 3-nodes Percona XtraDB Cluster and it works.
I think it may happen that mysqld on one node stops due to various reasons and so I think it may be necessary to use supervisor to manage mysqld for this situation. I have searched a lot but couldn’t find someone does this with Percona XtraDB Cluster. And adding supervisor to manage the cluster makes establishing cluster difficult.
So is there a need to use supervisor to manage mysqld for XtraDB Cluster? And if it’s neccessary, how to do it?
