(besides bindung to IN_ADDR_ANY = all addresses).

This is a disadvantage in HA Cluster configurations, where a cluster
framework stops/starts stand-alone mysql instances (non-NDB) on
physical servers within a cluster.

Within such frameworks, you don&#039;t want to bind to IN_ADDR_ANY
but rather to specific IP adresses (Sun speak: locical hostname addresses)
in order to allow the cluster framework to switch two instances of
an application onto the same cluster node (with the same (standard)
port number).

This is currently possible with mysql, but only for exacly one IP address
per mysql instance.

In situations where you need more than one IP address for an HA
instance, you either have to bind to IN_ADDR_ANY and somehow
make sure that no two mysql instances will run on any cluster node
at the same time, or find other means by which to provide the second
address (tcp forwarder, NAT on a firewall - whatever).

Both solutions are not ideal, so this feature request is for a configuration
option allowing more than one IP address to be specified.
