安装ipvsadm
# yum install ipvsadm
即可。
或者其它办法安装：
1.下载2.4版本
# wght -c http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.24.tar.gz
# tar zxf ipvsadm-1.24.tar.gz
# cd ipvsadm-1.24
如果报错：
添加链接：
# ln -s /usr/src/kernels/2.6.18-238.el5-i686/ /usr/src/linux
如果kernels里面什么都没有，就运行如下命令进行安装内核
#yum -y install openssl openssl-devel
安装keepalived
#wget http://www.keepalived.org/software/keepalived-1.1.20.tar.gz
http://nhylovezyh.blog.运维网.com/images/editer/InBlock.gif#tar xzvf keepalived-1.1.20.tar.gz
http://nhylovezyh.blog.运维网.com/images/editer/InBlock.gif#cd keepalived-1.1.20
http://nhylovezyh.blog.运维网.com/images/editer/InBlock.gif#./configure --prefix=/usr/local/keepalived
http://nhylovezyh.blog.运维网.com/images/editer/InBlock.gif#make && make install正确完成安装会显示如下信息：Keepalived configuration ------------------------
Keepalived version : 1.1.20
Compiler : gcc
Compiler flags : -g -O2
Extra Lib : -lpopt -lssl -lcrypto
Use IPVS Framework : Yes
IPVS sync daemon support : Yes
Use VRRP Framework : Yes
Use Debug flags : No
然后对keepalived做以下操作：http://nhylovezyh.blog.运维网.com/images/editer/InBlock.gif#cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/
http://nhylovezyh.blog.运维网.com/images/editer/InBlock.gif#cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig
http://nhylovezyh.blog.运维网.com/images/editer/InBlock.gif#mkdir /etc/keepalived
http://nhylovezyh.blog.运维网.com/images/editer/InBlock.gif#cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
http://nhylovezyh.blog.运维网.com/images/editer/InBlock.gif#cp /usr/local/keepalived/sbin/keepalived /usr/sbin/ 里面的有些出入：安装完keepalive后，需要添加服务，不要使用下面的命令：
http://nhylovezyh.blog.运维网.com/images/editer/InBlock.gif#check --add keepalived 应该使用如下命令：
先查看：
# chkconfig --list keepalived
如果没有，就添加
# chkconfig --add keepalived
然后开启在查看：
# chkconfig --list keepalived
keepalived 0:关闭 1:关闭 2:关闭 3:关闭 4:关闭 5:关闭 6:关闭
发现是关闭的，然后设置开机启动，并查看
# chkconfig keepalived on
# chkconfig --list keepalived
keepalived 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
修改配置文件
