问题四：在主机上启动heartbeat时，用ip add命令一直查看不到虚拟ip。

解决方案：
问题一:
错误日志提示：Client child command [/usr/lib/heartbeat/ipfail] is not executable。意思是这个文件不是可执行文件。则用find / -name ipfail命令去查找了一下ipfail这个文件，发现它是在usr/lib64/heartbeat/ipfail 这个目录下，因此在配置HA集群的时候要注意所使用的centos是32位还是64位的。用uname -i  进行查看.
问题二：
chmod 600 authkeys即可
问题三：
ERROR: Current node [133] not in configuration!表示节点不在配置文件中。主要要考虑主机名的配置上是否一致则对/etc/ha.d目录下的三个文件进行authkeys、authkeys、ha.cf
vim haresourses 
(node点)132  192.168.116.135/24/eth0:1 nginx
vim ha.cf
auto_failback on
node 133（node点）
node 132(node点)

ping 192.168.116.2
就是将所有用到的master和slave名字的地方都进行查看。主要不要忘记配置下hosts。
问题四：
注意查看下系统的80端口是否被占用
贴上所有相关的配置
