安装ipvsadm
[root@localhost lvs]# yum install ipvsadm即可。
或者其它办法安装：
1.下载2.4版本
[root@localhost lvs_keepalived]# wght -c
[root@localhost lvs_keepalived]# tar zxf ipvsadm-1.24.tar.gz
[root@localhost lvs_keepalived]# cd ipvsadm-1.24
如果报错：
添加链接：
[root@localhost ipvsadm-1.24]# 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
#tar xzvf keepalived-1.1.20.tar.gz #cd keepalived-1.1.20 #./configure --prefix=/usr/local/keepalived #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
#cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/ #cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig #mkdir /etc/keepalived #cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/ #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：
#check --add keepalived 应该使用如下命令：
先查看：
[root@localhost keepalived-1.1.20]# chkconfig --list keepalived
如果没有，就添加
[root@localhost keepalived-1.1.20]# chkconfig --add keepalived
然后开启在查看：
[root@localhost keepalived-1.1.20]# 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
[root@localhost keepalived-1.1.20]# chkconfig keepalived on
[root@localhost keepalived-1.1.20]# 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
