#tail /var/log/messages如果不启动从服务器，所以启动了主服务器以后要启动从服务器
原因：我想到一个问题，我记得上课的时候我只启动主上的heartbeat，从还为启动的时候，主上是不会启动vip和nginx服务的，这是因为，主有一个判断，只有当从节点一切准备就绪时，主才会正常工作。因为它要保证HA集群的可用性，如果从连heartbeat服务都不开启，只能说明这是一个单点，所以它要罢工！

# rm -f /etc/sysconfig/network-scripts/ifcfg-eth1 删掉eth1

但是从上ip addr，还是存在eth1的提示，但是已经把eth1这个网卡删除了应该就没问题了

PS：ha.cf上的ucast试验用eth0，线上建议用不同的网卡eth1或者用串口把两个连起来，什么是串口
