配置前提：
1.時間必須同步，建議使用ntp協議
2.節點之間必須要通過主機名互相通信；通信中使用的名字必須與其節點上"uname -n"命令展示出的名字一致
3.需要仲裁設備
4.雙方root用戶能基於ssh密鑰方式進行通信
5.本地資源必須能夠正常運行，本文將使用httpd作爲案例
注意：定義爲集羣服務中的任意資源都不能開機自動啓動，因爲他們將由CRM啓動
安裝方法：
[root@nod1 heartbeat1]# yum -y install net-snmp-libs libnet PyXML libltdl 注意配置epel源 [root@nod1 heartbeat1]# rpm -ivh heartbeat-2.1.4-12.el6.i686.rpm heartbeat-stonith-2.1.4-12.el6.i686.rpm heartbeat-pils-2.1.4-12.el6.i686.rpm Preparing... ########################################### [100%] 1:heartbeat-pils ########################################### [ 33%] 2:heartbeat-stonith ########################################### [ 67%] 3:heartbeat ########################################### [100%]

節點1：建立加密關聯
ssh-keygen -P ''ssh-copey-id -i .ssh/id_rsa.pub root@node2
[root@nod1 ~]# ssh nod2 'date';date 保持兩個節點時間同步Mon Oct 5 17:38:47 HKT 2015Mon Oct 5 17:38:47 HKT 2015
[root@nod1 ~]# scp /etc/hosts nod2:/etc/hosts 兩個節點的hosts文件保持一致hosts 100% 228 0.2KB/s 00:00

配置文件設置；
cd /usr/share/doc/heartbeat-2.1.4cp -p authkeys haresources ha.cf /etc/ha.d #將備用的配置文件拷貝到配置目錄中 ha.cf:heartbeat的主配置文件，authkeys:集羣信息加密算法及密鑰,haresources:heartbeat v1的CRM配置接口cd /etc/ha.d/chmod 600 authkeys 修改權限400或600
修改ha.cf配置：
vim ha.cflogfile /var/log/ha-log#logfacility local0mcast eth0 228.203.101.1 694 1 0 採用多播地址，本地組播地址：239.0.0.0-239.255.255.255，僅在特定的本地範圍內有效 node nod1.mageedu.comnode nod2.mageedu.com 加入高可用集羣的計算機ping 192.168.1.1 仲裁設備，判斷計算機是否可用的標準compression bz2 選擇壓縮
vim authkeys auth 1 1 sha1 343434349 設置加密，可以使用openssl rand -hex 6生成加密密碼
vim haresouces: nod1.mageedu.com 192.168.1.15/24/eth0/192.168.1.255 httpd Haresources文件用於指定雙機系統的主節點、集羣IP、子網掩碼、廣播地址以及啓動的服務等集羣資源s
scp -p authkeys haresouces ha.cf node2:/etc/ha.d/ 確保主機2 配置，文件屬性相同－p
service heartbeart start; ssh node2 'service heartbeat start'啓動服務，訪問外網地址能正常訪問
tail /var/log/ha-log 查看日誌
cd /usr/lib64/heartbeat/ ./hb_standby 不作爲主 ./hb_takeover 作爲主 資源轉化用
