logfacility local0
keepalive 2
deadtime 30
warntime 10
initdead 60
udpport 694
ucast eth0 192.168.238.133
auto_failback on
node linux-server
node linux-client
ping 192.168.238.1
respawn hacluster /usr/lib64/heartbeat/ipfail

respawn hacluster /usr/lib64/heartbeat/ipfail
yum install -y nginx
/etc/init.d/heartbeat start
环境测试
echo "this is heartbeat server11111111111111111111111111" > /usr/share/nginx/html/index.html 主机
echo "this is heartbeat server22222222222222222222222222" > /usr/share/nginx/html/index.html 备机
客户端浏览器访问192.168.238.100
出现“this is heartbeat server11111111111111111111111111" 正常
在服务器主机上添加一条防火墙规则，拒绝ping
iptables -A INPUT -p icmp -j DROP
客户端浏览器访问192.168.238.100
出现“this is heartbeat server22222222222222222222222222" 正常
删除刚才添加的防火墙规则
iptables -D INPUT -p icmp -j DROP
客户端浏览器访问192.168.238.100
出现“this is heartbeat server11111111111111111111111111" 正常
