<一,openStack service Components ​HA scheme design>


1.1,OpenStack ​services that are stateless​ include:

nova-api, nova-conductor, glance-api, keystone-api, neutron-api and nova-scheduler


1.2,OpenStack ​services that are stateful include:

Pacemaker interacts with applications through resource agents (RAs), of which it supports

over 70 natively. Pacemaker can also easily use third-party RAs. An OpenStack high-availability

configuration uses existing native Pacemaker RAs (such as those managing MySQL

databases or virtual IP addresses), existing third-party RAs (such as for RabbitMQ), and native

OpenStack RAs (such as those managing the OpenStack Identity and Image Services)
