heartbeat之part03

基本的排錯步驟（從上往下）
ping 127.0.0.1ping的通說明tcp協議棧沒有問題
ping 主機地址 ping的通說明網卡沒有問題
ping 路由器默認網關 ping的通說明包能夠到達路由器
最後 ping DNS服務器地址
安裝heartbeat
 
 
 
 關閉兩臺的防火牆service iptables stop

[root@data-1-2 ha.d]# less ha.cf
ha.cf詳細說明
debugfile /var/log/ha-debug調試日誌存放位置
logfile  /var/log/ha/ha-log日誌存放位置
logfacility    local在syslog服務中配置經過local設備接收日誌
keepalive 2    指定心跳間隔爲2秒
deadtime 30    指定備用節點在30秒內沒有收到主節點的信號，就接收主機的資源
warntime 10    指定心跳延遲的時間爲10秒，當10秒鐘內備份不能收到主節點的心跳信號時，就往日誌
中寫入一個警告日誌，此時不會切換業務
initdead 120   指定heartbeart首次運行後，須要等待120秒才啓動主服務器
任何資源，改選項用於解決這種事情產生的時間間隔值，取值至少deadline的
兩倍，宕機啓動時會遇到綁定很慢，爲正常現象，這時改值長的緣由
#bcast eth指定心跳使用以太網廣播方式進行廣播，如使用兩個實際網絡
來傳遞心跳則#bcast eth0 eth1
mcast eth2 225.0.0.1 694 10 694是端口
auto_failback_on 用來定義主節點恢復後，是否將資源服務自動切回
node data-1-1 主機節/點主機名，能夠經過uname -n查看
node data-1-2備用節點名
crm no是否開啓cluster resource manager集羣資源管理功能

authkey權限必須600
能夠設置的認證方法crc,shal(比較好),md5
ha.cnf
