heartbeat實現高可用集群（2）

[[ heartbeat v2 + crm ]]

環境
   node1 192.168.1.35
   node2 192.168.1.36
   fip 192.168.1.81
   daemon httpd
ha web service
 ip httpd
node1&2
# vim ha.cf
 crm on
# cd
# rpm -ivh heartbeat-gui-2.1.4-12.el6.x86_64.rpm
# service heartbeat start
node1&2
# crm_mon 顯示當前crm集群狀態
# ss -tnlp
 mgmtd :5560
# rpm -ql heartbeat-gui
 /usr/bin/hb_gui
 note:hb_gui運行要以特定用戶登陸才能做配置
# tail /etc/passwd
 hacluster:x:496:493:heartbeat 
# echo "queen" | passwd --stdin hacluster
node1
# hb_gui
 -Linux HA Management Client
   -Connection(登陸)
   -Resources(定義資源)
       -native webip IPaadr 192.168.1.81 
       -native webserver httpd
       -group webservice (要使用組要先定義組，再定義資源)
   -Constraints(約束)
       -colocation webser_with_webip INFINITY false
       -orders webserver_after_webip INFINITY 
note：刪除：先刪約束，后刪資源
