红帽全球峰会4.7. Configuring the load balancer resource agent
After creating the health probe, you must configure the load balancer resource agent. This resource agent runs a service that responds health probe requests from the Azure load balancer and removes cluster nodes that do not respond requests.
Prerequisites
- You have completed the process of creating an Azure load balancer.
Procedure
Install the
nmap-ncatresource agents on all nodes:# dnf install nmap-ncat resource-agents-cloudPerform the following steps on a single node:
Create the
pcsresources and group by using theFrontendIPload balancer for theIPaddr2address:# pcs resource create resource-name IPaddr2 ip="10.0.0.7" --group <cluster_resources_group>Configure the
load balancerresource agent:# pcs resource create resource-loadbalancer-name azure-lb port=port-number --group <cluster_resources_group>
