安装步骤如下：
ln -s /usr/src/kernels/2.6.9-89.0.9.EL-smp-x86_64/ /usr/src/linux
2.6.9-89.0.9.EL-smp-x86_64与uname -a内核配对。
下载
wget http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.24.tar.gz
wget http://www.keepalived.org/software/keepalived-1.1.15.tar.gz

安装
tar zxvf ipvsadm-1.24.tar.gz
cd ipvsadm-1.24
make && make install
cd ..
tar zxvf keepalived-1.1.15.tar.gz
cd keepalived-1.1.15
注意项

Centos5.0以下需要修改以下configure才能通过。
vi /usr/src/linux/include/linux/types.h
/*
typedef __u16 __bitwise __sum16;
typedef __u32 __bitwise __wsum;
*/

./configure
make && make install

cp /usr/local/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/
cp /usr/local/etc/sysconfig/keepalived /etc/sysconfig/
mkdir /etc/keepalived
cp /usr/local/etc/keepalived/keepalived.conf /etc/keepalived/
cp /usr/local/sbin/keepalived /usr/sbin/

service keepalived start

为了配合LVS平台，还需如下操作
1、安装RRDTOOL
2、配置master端流量rrd数据采集
cd /home
wget http://tianyalvs.googlecode.com/files/lvs-rrd.tar.gz
tar -zxvf lvs-rrd.tar.gz
vi lvs-rrd/lvs.rrd.update
根据用户实际情况来修改如下参数

引用

RRDTOOL="/usr/bin/rrdtool"
IPVSADM="/sbin/ipvsadm"
WORKDIR="/home/lvs-rrd/performance"

3、定制采集作业
*/2 * * * * /home/lvs-rrd/lvs.rrd.update 2> /dev/null > /dev/null

4、LVS管理平台端会定期来捉取performance中的*.rrd文件，用户可以通过ssh或ftp，系统默认采用rsync+ssh方式，配置可参考实践rsync+ssh实现代码同步

问题总结
1、make keepalived时提示：
make[2]: Leaving directory `/home/install/lvs/keepalived-1.1.15/keepalived/core'
make[2]: Entering directory `/home/install/lvs/keepalived-1.1.15/keepalived/check'

*/

2、master、backup的/var/log/messagse显示
Nov 23 17:46:41 SN2008-06-070 Keepalived_vrrp: receive an invalid ip number count associated with VRID!
Nov 23 17:46:41 SN2008-06-070 Keepalived_vrrp: bogus VRRP packet received on eth0 !!!

解决：

修改 virtual_router_id 的值，与网络中不能重复。

3、在/var/log/messages中Keepalived_vrrp不生效，即无vrrp日志。
解决：

重新编译源码包，可能是由于修改types.h后才configure。
