拓撲圖：

1、LVS配置腳本：

需要安裝：ipvsadm-1.24-10.i386.rpm

vi ?/etc/rc.d/init.d/lvsdr

#!/bin/bash

vip=192.168.0.116

web1=192.168.0.104

web2=192.168.0.114

./etc/rc.d/init.d/functions

case "$1" in

start)

echo "start

lvs-dr"

echo "1"

> /proc/sys/net/ipv4/ip_forward

ifconfig eth0:0 ${vip} broadcast ${vip} netmask 255.255.255.255

up

route add -host ${vip} dev eth0:0

ipvsadm -C

ipvsadm -A -t ${vip}:80 -s rr

ipvsadm -a -t ${vip}:80 -r ${web1}:80 -g

ipvsadm -a -t ${vip}:80 -r ${web2}:80 -g

ipvsadm

;;

stop)

echo "stop

lvs-dr"

echo "0"

>/proc/sys/net/ipv4/ip_forward

ipvsadm -C

ifconfig eth0:0 down

;;

*)

echo

"Usage:$0 {start|stop}"

exit 1

esac

service lvsdr start #啟動服務

service lvsdr stop?#停止服務

2、lvsweb1配置

vi?/etc/rc.d/init.d/lvsweb

#!/bin/bash

vip=192.168.1.116

./etc/rc.d/init.d/functions

case "$1" in

start)

echo "start lvs-web1"

ifconfig lo:0 ${vip} broadcast ${vip} netmask 255.255.255.255

up

route add -host ${vip} 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

;;

stop)

echo "stop lvs-web1"

ifconfig lo:0 down

echo "0"

>/proc/sys/net/ipv4/conf/lo/arp_ignore

echo "0"

>/proc/sys/net/ipv4/conf/lo/arp_announce

echo "0"

>/proc/sys/net/ipv4/conf/all/arp_ignore

echo "0"

>/proc/sys/net/ipv4/conf/all/arp_announce

;;

*)

echo "Usage:$0 {start|stop}"

exit 1

esac

啟動腳本：

[root@linux-2 local]# service lvsweb start

start lvs-web1

3、lvsweb2配置

vi ?/etc/rc.d/init.d/lvsweb

#!/bin/bash

vip=192.168.1.116

./etc/rc.d/init.d/functions

case "$1" in

start)

echo "start lvs-web2"

ifconfig lo:0 ${vip} broadcast ${vip} netmask 255.255.255.255

up

route add -host ${vip} 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

;;

stop)

echo "stop lvs-web2"

ifconfig lo:0 down

echo "0"

>/proc/sys/net/ipv4/conf/lo/arp_ignore

echo "0"

>/proc/sys/net/ipv4/conf/lo/arp_announce

echo "0"

>/proc/sys/net/ipv4/conf/all/arp_ignore

echo "0"

>/proc/sys/net/ipv4/conf/all/arp_announce

;;

*)

echo "Usage:$0 {start|stop}"

exit 1

esac

啟動腳本：

[root@linux-3 ~]# service lvsweb start

start lvs-web2

4，監控LVS (在LVS服務器上安裝)

1、安裝rrdtool工具

tar zxvf rrdtool-1.2.30.tar.gz

cd rrdtool-1.2.30

./configure --prefix=/usr/local/rrdtool

make&&make

install

echo “/usr/local/rrdtool/lib”

>>/etc/ld.so.conf

ldconf -v

2、安裝lvs-rrd

tar tar zxvf lvs-rrd-v0.7.tar.gz

mv lvs-rrd-v0.7 /var/www/html/lvs-rrd

3、配置lvs-rrd

cd?/var/www/html/lvs-rrd

vi?lvs.rrd.update (只需要配置指定的路徑即可)

RRDTOOL="/usr/local/rrdtool/bin/rrdtool"

IPVSADM="/sbin/ipvsadm"

WORKDIR="/var/www/html/lvs-rrd"

vi graph-lvs.sh

WORKDIR="/var/www/html/lvs-rrd"

RRDTOOL="/usr/local/rrdtool/bin/rrdtool"

GRAPHS="$WORKDIR/graphs"

WEBPATH="/lvs-rrd/graphs"

4、設置權限：

chown -R apache.apache graphs/

5 、使用crontab 更新

crontab -e

* * * * * /var/www/html/lvs-rrd/lvs.rrd.update 2>

/dev/null > /dev/null
