Each node is edited haproxy.cfg.
This is just a test haproxy, so only load balancing for dashboard, actually dashboard is not installed on the node.


Because the cluster resource needs to be bound to the VIP, the kernel parameters of each node need to be modified:
# echo ' net.ipv4.ip_nonlocal_bind = 1 ' >>/etc/sysctl.conf
# sysctl-p


Increase the Haproxy service resources in the cluster:
# CRM Configure primitive Haproxy lsb:haproxy op monitor interval= "30s"
"Lsb:haproxy" represents the Haproxy service.

ERROR:lsb:haproxy:got no meta-data, does this RA exist?
ERROR:lsb:haproxy:got no meta-data, does this RA exist?
ERROR:lsb:haproxy:no such resource agent
Still want to commit (y/n)? N

It seems that the CRM command does not recognize the "haproxy" service. See what services CRM is currently able to identify:
# CRM RA List LSB
Netconsole Network

Netconsole and network are located in the/ETC/RC.D/INIT.D directory, which is the only service script Centos7 by default, presumably to create a service script for haproxy in this directory (each node):
# Vi/etc/rc.d/init.d/haproxy

The contents are as follows:
#!/bin/bash

Case "$" in
Start
Systemctl Start Haproxy.service
;;
Stop
Systemctl Stop Haproxy.service
;;
Status
Systemctl status-l Haproxy.service
;;
Restart
Systemctl Restart Haproxy.service
;;
*)
Echo ' $ = Start|stop|status|restart '
;;
Esac


Remember to grant executable permissions:
chmod 755/etc/rc.d/init.d/haproxy


Reconfirm that the CRM command recognizes "Haproxy":
# CRM RA List LSB
Haproxy Netconsole Network
Already have haproxy, the service haproxy Status command is also available, try to create a Haproxy service resource again.

MYVIP (OCF::HEARTBEAT:IPADDR2): Started controller2
Haproxy (lsb:haproxy): Started Controller3

Currently Haproxy resources on the node Controller3, on the Controller3 view Haproxy service status, is active:
# Systemctl Status-l Haproxy.service


Defining Haproxy and VIPs must be run on the same node:
# CRM Configure colocation haproxy-with-public-ips Infinity:haproxy MYVIP

Define to take over VIP before starting Haproxy:
# CRM Configure Order HAPROXY-AFTER-VIP MANDATORY:MYVIP Haproxy

Deploying Haproxy instances on the control nodes of OpenStack has become a consensus. The number of instances is preferably odd, such as 3, 5, and so on.
