在安装heartbeat、corosync以及pacemaker这些Linux-HA软件时，没有一个可靠的yum源对于安装者简直就是一场噩梦，光是那一大串rpm包就不知道到哪儿下载去，就算是费了九牛二虎之力把所有需要的包都找到了，版本对不对？操作系统支不支持？每个rpm包又需要哪些依赖？想想就奔溃了！本博主之前刚好配置过一些软件的HA，这里不妨把用到的yum源分享出来，供刚接触Linux-HA软件的人参考。该yum源的使用也很简单，将其拷贝到/etc/yum.repos.d/下面，替换之前的Cent-Base.repo。
# CentOS-Base.repo
#
# The mirror system uses theconnecting IP address of the client and the
# update status of each mirror topick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually pickingother mirrors.
#
# If the mirrorlist= does not workfor you, as a fall back you can try the
# remarked out baseurl= lineinstead.
