Configuring High Availability
|
|
=============================
|
|
|
|
|project| supports high availability of the controller services using
|
|
Pacemaker. To enable this feature, you need at least three controller
|
|
nodes, enable Pacemaker as the resource manager and specify an NTP
|
|
server.
|
|
|
|
Creating an environment file and adding the following arguments to your
|
|
`openstack overcloud deploy` command will do the trick::
|
|
|
|
$ cat ~/environment.yaml
|
|
parameter_defaults:
|
|
ControllerCount: 3
|
|
|
|
-e environment.yaml -e /usr/share/openstack-tripleo-heat-templates/environments/puppet-pacemaker.yaml --ntp-server pool.ntp.org
