一、仅lvs服务器端安装
yum install ipvsadm openssl-devel popt popt-devel libnl-devel
cd /opt/src/
tar xzvf keepalived-1.2.7.tar.gz
cd keepalived-1.2.7
./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/
修改/etc/keepalived/keepalived.conf文件
[root@WEB ~]# cat /etc/keepalived/keepalived.conf
! Configuration File for keepalived

}

}

}

delay_before_retry 2
connect_port 80
}
}
real_server 192.168.1.68 80 {

TCP_CHECK {
connect_timeout 30
nb_get_retry 3
delay_before_retry 2
connect_port 80
}
}
}
[root@WEB ~]#
[root@WEB ~]# service ipvsadm start
[root@WEB ~]# service keepalived start
注意：
echo "1" > /proc/sys/net/ipv4/ip_forward
二、实际服务器端的操作
将网关设置为lanvip的地址192.168.1.88
三、lvs查看
ipvsadm -ln
ipvsadm -lnc
ipvsadm -l -n --stats
