[ClusterLabs] Which fence agent is needed for an Apache web server cluster?

[Jason Long]

Hello,
How To Configure High-Availability Cluster on CentOS 7 / RHEL 7 tutorial In "https://www.itzgeek.com/how-tos/linux/centos-how-tos/configure-high-avaliablity-cluster-on-centos-7-rhel-7.html" address, used below command:

# yum install pcs fence-agents-all -y

Is "fence-agents-all" package needed?

Thank you.
