heartbeat部署指南
两台机器的环境:data-1-1 eth0 10.0.0.7 eth1 172.16.1.7 eth2 10.0.10.7
data-1-2 eth0 10.0.0.8 eth1 172.16.1.8 eth2 10.0.10.8
# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.10.7 data-1-1
10.0.10.8 data-1-2
# route add -host 10.0.10.8 dev eth2 互相添加路由
# route add -host 10.0.10.7 dev eth2 互相添加路由
更新yum源：
# mkdir /home/oldboy/tools -p
# cd /home/oldboy/tools
# wget http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
# rpm -ivh epel-release-6-8.noarch.rpm
# rpm -qa|grep epel 检查是否已安装上
epel-release-6-8.noarch
# sed -i 's#keepcache=0#keepcache=1#g' /etc/yum.conf是否留下软件包
# yum install heartbeat* -y 都需要安装heartbeat软件及其依赖
启动脚本:/etc/init.d/heartbeat
配置文件目录：/etc/ha.d
资源控制目录：/etc/ha.d/resource.d
核心的配置文件：authkey haresource ha.cf
配置文件模版放置目录：/usr/share/doc/heartbaeat-3.0.4
ha.cf配置文件：
# cat /etc/ha.d/ha.cf
debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility local0
keepalive 2
deadtime 30
warntime 10
initdead 60
udpport 694
mcast eth0 225.0.0.1 694 1 0
auto_failback on
node data-1-1
node data-1-2
crmno
authkeys配置文件
# echo chenjisong|sha1sum
8e901fca8d58aa2e2b315b4af1769ffe54e5257a-
# cat authkeys
auth 1
1 sha1 8e901fca8d58aa2e2b315b4af1769ffe54e5257a
# chmod 600 authkeys
haresources 配置文件
# cat haresources
data-1-1 IPaddr::10.0.0.17/24/eth0 ====虚拟IP
data-1-2 IPaddr::10.0.0.18/24/eth0 ====虚拟IP
# /etc/ha.d/resource.d/IPaddr 10.0.0.17/24/eth0 start
# ip a|grep 10.0.0.17
inet 10.0.0.17/24 brd 10.0.0.255 scope global secondary eth0
# /etc/ha.d/resource.d/IPaddr 10.0.0.18/24/eth0 start
# ip a|grep 10.0.0.18
inet 10.0.0.18/24 brd 10.0.0.255 scope global secondary eth0
两台机器上面安装httpd
然后启停heartbeat服务，查看ip漂移过程
