heartbeat-pils-2.1.3-3.el5.centos.x86_64.rpm
heartbeat-stonith-2.1.3-3.el5.centos.x86_64.rpm
PyXML-0.8.4-4.x86_64.rpm 系统环境：
CentOS 5.4 64-bit
HA1 10.0.0.108
HA1 10.0.0.109
web1 10.0.0.110
web2 10.0.0.111
VIP 10.0.0.100
ipvsadm-1.24安装
rpm -ivh ipvsadm-1.24-10.x86_64.rpm
/sbin/ipvsadm heartbeat 安装
rpm -ivh heartbeat-pils-2.1.3-3.el5.centos.x86_64.rpm
rpm -ivh heartbeat-stonith-2.1.3-3.el5.centos.x86_64.rpm
rpm -ivh PyXML-0.8.4-4.x86_64.rpm
rpm -ivh heartbeat-2.1.3-3.el5.centos.x86_64.rpm 注：若heartbeat一次未安装好，再装一次
rpm -q heartbeat -d //查看安装路径
echo "service heartbeat start" >> /etc/rc.localhttp://www.elain.org/wp-includes/js/tinymce/plugins/wordpress/img/trans.gif
配置heartbeat
cd /usr/share/doc/heartbeat-2.1.3/
cp authkeys ha.cf haresources /etc/ha.d/
cd /etc/ha.d
vi authkeys
#去掉注释 设置校验模式
auth 1
1 crc
#2 sha1 HI!
#3 md5 Hello!
echo "10.0.0.108HA1" >>/etc/hosts
echo "10.0.0.109HA2" >>/etc/hosts
vi haresources
#添加：（约44行下面）
HA1 10.0.0.100 vip.sh
vi ha.cf
#去掉注释（约95行）
bcast eth0
#去掉注释并修改（约125行）
ucast eth0 10.0.0.109
#去掉注释并修改（约215、216行）
node HA1
node HA2
chmod 600 authkeys
vi /etc/init.d/vip.sh
#/sbin/bash!
ifconfig eth0:0 10.0.0.100 broadcast 10.0.0.100 netmask 255.255.255.255 up
route add -host 10.0.0.100 dev eth0:0
#setup ipvs
ipvsadm -C
ipvsadm -A -t 10.0.0.100:80 -s rr
ipvsadm -a -t 10.0.0.100:80 -r 10.0.0.110 -g
ipvsadm -a -t 10.0.0.100:80 -r 10.0.0.111 -g
ipvsadm HA2的配置和HA1一样，可以直接上传HA1的authkeys ha.cf haresources三个文件
sftp 10.0.0.108
cd /etc/ha.d
get authkeys ha.cf haresources
quit 修改HA2中ha.cf里（约125行）为：
ucast eth0 10.0.0.108 把vip.sh放到LVS服务器
vi /etc/init.d/vip.sh //放到这里开机自启动
chmod 755 /etc/init.d/vip.sh
/etc/init.d/vip.sh
echo "service heartbeat start" >> /etc/rc.local lvs.sh
#/sbin/bash!
ifconfig lo:0 10.0.0.100 broadcast 10.0.0.100 netmask 255.255.255.255 up
route add -host 10.0.0.100 dev lo:0
echo "1">/proc/sys/net/ipv4/conf/lo/arp_ignore
echo "2">/proc/sys/net/ipv4/conf/lo/arp_announce
echo "1">/proc/sys/net/ipv4/conf/all/arp_ignore
echo "2">/proc/sys/net/ipv4/conf/all/arp_announce
sysctl -p web1web2安装WEB服务
安装过程略
注：
把lvs.sh放到WEB服务器
#vi /etc/init.d/lvs.sh //放到这里开机自启动
#chmod 755 /etc/init.d/lvs.sh
#/etc/init.d/lvs.sh 得出结论：
不断刷新10.0.0.100，会轮流显示web1和web2页面
