"Linux" "Services" "Openstack" Installation and Deployment (3. Cluster software corosync,pacemake,pcs)

1. Introduction:

Official cluster configuration document: https://docs.openstack.org/ha-guide/controller-ha-pacemaker.html

2. Installation:

In fact, management tools to use CRMSH or PCs are OK, but as redhat, I still choose PCs, but the installation process a bit of a problem

The default Python-clufter version is 0.50, but installing PCs requires more than 0.59, so if you've installed Python-clusfter, please uninstall them yourself.

Yum Remove Python-clufter

Do not install the classmate please do
