RHEL安装heartbeat报错： heartbeat: udpport setting must precede media statements

环境如下：

[root@master ~]# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 5.5 (Tikanga)
[root@master ~]# uname -a
Linux master 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
[root@master ~]# 

安装Heartbeat-2.1.3，出现如下错误：

看不懂什么意思，然后google查，无功而返，仔细查看原来的安装指导，发现里面有提到authkeys配置文件权限必须为600，

灵光一闪：难道是因为这个？但怎么看都不像啊。。。。。。

虽然怀疑，但还是抱着死马当活马医的想法，尝试了一下，oh my god， 果然解决了！

[root@master ha.d]# service heartbeat start

至于原因，没有时间详细研究，有兴趣的同学可以试试。
