 Pacemaker는 Heartbeat Network으로 구성되기 때문에 다음과 같이 `/etc/hosts` 파일에 IP를 설정한다.
 
+```bash
+# cat /etc/hosts
+
+127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
+
+::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
+
+172.16.0.211 zabbix211
+172.16.0.217 zabbix217
+```
+
+1. 패키지 설치 및 기본구성
+
+```bash
+# yum install pcs fence-agents-all
+# systemctl start pcsd; systemctl enable pcsd
+
+# echo 패스워드 | passwd --stdin hacluster
+# pcs cluster auth zabbix211 zabbix217
+
+# pcs cluster setup --start --name ZABBIX zabbix211 zabbix217
+# pcs cluster enable --all
+
+# pcs property set stonith-enabled=false
+# pcs property set no-quorum-policy=ignore
+```
+
+2. VIP 클러스터 리소소 구성
+
+```bash
+# pcs resource create PU-VIP IPaddr2 ip=61.100.0.244 cidr_netmask=32 nic=eth0 op monitor interval=10s timeout=30s on-fail=standby
+# pcs resource create PR-VIP IPaddr2 ip=172.16.0.244 cidr_netmask=32 nic=eth1 op monitor interval=10s timeout=30s on-fail=standby
+```
+
+3. Zabbix Server 요소별 리소스 구성
+
+```bash
+# pcs resource create HTTPD systemd:httpd
+# pcs resource create PHP-FPM systemd:rh-php72-php-fpm
+# pcs resource create GRAFANA systemd:grafana-server
+# pcs resource create ZABBIX systemd:zabbix-server
+```
+> GRAFANA는 Zabbix의 그래프 인터페이스를 개선하기 위한 연동이다. Grafana는 아주 훌륭한 그래프를 제공해 준다.
+
+4. 클러스터 리소스의 순서 제약조건을 구성
+
+```bash
+# pcs constraint order start PU-VIP then start PR-VIP
+# pcs constraint order start PR-VIP then start PHP-FPM
+# pcs constraint order start PHP-FPM then start HTTPD
+# pcs constraint order start HTTPD then start GRAFANA
+# pcs constraint order start GRAFANA then start ZABBIX
+```
+
+5. 요소별 리소스가 위치하는 제약조건을 구성
+
+```bash
+# pcs constraint colocation add PU-VIP with PR-VIP
+# pcs constraint colocation add PR-VIP with PHP-FPM
+# pcs constraint colocation add PHP-FPM with HTTPD
+# pcs constraint colocation add HTTPD with GRAFANA
+# pcs constraint colocation add GRAFANA with ZABBIX
+# pcs constraint location ZABBIX prefers zabbix211=100
+```
+
+!참고 : 다음은 Zabbix Proxy의 Pacemaker 구성내역이다.
+
+```bash
+# pcs resource create PU-VIP IPaddr2 ip=61.100.0.220 cidr_netmask=32 nic=eth0 op monitor interval=10s timeout=30s on-fail=standby
+# pcs resource create PR-VIP IPaddr2 ip=172.16.0.220 cidr_netmask=32 nic=eth1 op monitor interval=10s timeout=30s on-fail=standby
+
+# pcs resource create ZABBIX-PROXY systemd:zabbix-proxy
+# pcs constraint order start PU-VIP then start PR-VIP
+# pcs constraint order start PR-VIP then start ZABBIX-PROXY
+
+# pcs constraint colocation add PU-VIP with PR-VIP
+# pcs constraint colocation add PR-VIP with ZABBIX-PROXY
+# pcs constraint location ZABBIX-PROXY prefers zabbix-proxy224=100
+```
