centos6.x下yum安装heartbeat

[[email protected] ~]# yum -y install heartbeat      #<===centos6.x下yum默认安装heartbeat版本是3.0.4，centos7.x下只能编译安装
[[email protected] ~]# cd /usr/share/doc/heartbeat-3.0.4/
[[email protected] heartbeat-3.0.4]# cp {ha.cf,haresources,authkeys} /etc/ha.d/
[[email protected] heartbeat-3.0.4]# cd /etc/ha.d/
[[email protected] ha.d]# chmod 600 /etc/ha.d/authkeys 
[[email protected] ha.d]# ip addr add 10.0.0.30/24 broadcast 10.0.0.255 dev eth0   #<===添加辅助VIP
[[email protected] ha.d]# cat ha.cf

[[email protected] ~]# netstat -lntup|grep heartbeat

[[email protected] ha.d]# chkconfig --add heartbeat
[[email protected] ha.d]# chkconfig --level 3 heartbeat on

以上是单台heartbeat服务器配置，生产中双机热备heartbeat配置文件{ha.cf，authkeys，haresources}内容是一样的，这里心跳线配置步骤省略....

如遇安装报错，查看 /var/log/ha-log日志排查错误即可，heartbeat相对来说还是简单的。
