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

[[email protected] ~]# 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

[[email protected] ~]# route add -host 10.0.10.8 dev eth2   互相添加路由

[[email protected] ~]# route add -host 10.0.10.7 dev eth2   互相添加路由

更新yum源：

[[email protected] ~]# mkdir /home/oldboy/tools -p

[[email protected] ~]# cd /home/oldboy/tools

[[email protected] tools]# wget http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

[[email protected] tools]# rpm -ivh epel-release-6-8.noarch.rpm

[[email protected] yum.repos.d]# rpm -qa|grep epel        检查是否已安装上

epel-release-6-8.noarch

[[email protected] yum.repos.d]# sed -i ‘s#keepcache=0#keepcache=1#g‘ /etc/yum.conf  是否留下软件包

[[email protected] yum.repos.d]# 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：

[[email protected] ha.d]# 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

crm  no

authkeys配置文件

[[email protected] html]# echo chenjisong|sha1sum

8e901fca8d58aa2e2b315b4af1769ffe54e5257a  -

[[email protected] ha.d]# cat authkeys

auth 1

1 sha1 8e901fca8d58aa2e2b315b4af1769ffe54e5257a

[[email protected] ha.d]# chmod 600 authkeys

haresources 配置文件

[[email protected] ha.d]# 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

[[email protected] ha.d]# /etc/ha.d/resource.d/IPaddr 10.0.0.17/24/eth0 start

[[email protected] ha.d]# ip a|grep 10.0.0.17

inet 10.0.0.17/24 brd 10.0.0.255 scope global secondary eth0

[[email protected] ha.d]# /etc/ha.d/resource.d/IPaddr 10.0.0.18/24/eth0 start

[[email protected] ha.d]# 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
